The future is now: helpful car diagnostic apps and more

Mechanic using laptop photoEver since 1996, On-Board Diagnostics generation two (OBD-II) has required all new vehicles manufactured in the United States to have self-diagnostic and reporting capabilities. This gives you access to the status of your vehicles’ systems in real time using a standardized series of diagnostic trouble codes (DTCs).

This is accomplished through a 16-pin connector mounted near the instrument panel that provides four-digit codes for four main areas: P for powertrain; U for computer; C for chassis; and B for body.

Car apps 1Diagnostic scanning tools make DIYing it so much easier – and here are apps that you can access from your smart phone to help you do diagnostics right. Use the app on the road, order the appropriate car parts and you’re off and running on your latest car repair.

Actron U-Scan and more

With U-Scan from Actron, you can discover the cause of the check engine light by plugging a device in your vehicle’s adapter and reading the relevant code definitions. With the QuickCheck™ feature, you can use your Android or Apple device to read the codes appearing on your vehicle, and then, when appropriate, erase them to turn off the check engine light. You can also monitor your emissions status, and maintain a log of vehicle tests and procedures and more.

Advanced features include:

  • Powertrain enhanced data ($7.99 per vehicle or $15.99 for all these manufacturers for most vehicles that are 1996 or newer: GM, Ford, Chrysler, Honda, Hyundai, Nissan and Toyota): Get access to Powertrain codes and definitions. U-Scan’s freeze frame data describes the vehicle’s conditions at the time when the trouble code first appeared. More than 300 sensor/data items are available.
  • ABS codes and definitions ($5.99 per vehicle or $29.99 for all listed manufacturers): Discover the likely causes of ABS warning lights.
  • CodeConnect® ($12.99 per vehicle or $39.99 for all vehicles): More than 4.3 million fixes are available in this database, verified by ASE-certified technicians. Note: You must first purchase the powertrain enhanced data and/or ABS codes and definitions before buying and using CodeConnect.
  • Airbag codes and definitions ($7.99 per vehicle or $39.99 for list manufacturers): Access the most likely causes of airbag warning lights.

It never hurts to compare. In The 6 Best On-Board Diagnostics (OBD) Apps for your Car, you can get more information on other similar apps.

What’s next: car key apps?

In June 2015, the New York Times published an article titled The Future of Car Keys? Smartphone Apps, Maybe, predicting how the car key and fob might evolve. Right now, if you own a Tesla, BMW, General Motors or Volvo, you might already own a key fob that allows you to start the engine, unlock doors, turn on heat and monitor the battery remotely. With the PEPS keys (passive entry, passive start), you don’t even need to remove the fob from your pocket. Its very nearness to the car allows you to unlock doors with a touch, and to start the car with a button push.Car apps diagram

What’s next?

Experts don’t believe that a smartphone app will replace a key, not when a slow data network or dead phone battery would keep you out of your car. Plus, who wants to pay a monthly data subscription plan, which would likely be part of the deal, if you only got what a car fob previously provided? Especially with the complications provided by slow data networks and dead phone batteries? What would be the point?

Hakan Kostepen, the executive director for product planning strategy for Panasonic Automotive Systems, says that keys will eventually carry driver preferences, such as seating positions and favorite audio choices, even when you’re in a rental car. A smartphone app could work with the key data to recommend places to visit, eat and so forth, based on your known preferences.

Finally, Audi and Volvo are experimenting with groceries and packages being delivered to car trunks and the owner being notified. Car key usage would be authorized for a one-time use.

Exclusive Coverage: DuPont Registry HQ Cars & Coffee

DuPont 4

The crisp morning air greets a diligent car fan on a Saturday morning when the garage opens at 6:14 AM. It’s time for DuPont Registry Headquarters Cars & Coffee in St. Petersburg, Florida. The early morning car fanatic pulls off a cover and backs the 1965 introductory-year Porsche 911 onto the driveway. A quick dust off and it’s ready to go. This car doesn’t see the light of day often but the roads are quiet and the crowds are calm, so there’s no better time than now.

What is the DuPont Registry Headquarters Cars & Coffee event? Let us set the scene.

The DuPont Registry website lists “highline luxury cars for sale by auto dealers and private owners. In addition, consumers can search for wheels, car accessories, tuning, racing schools, exotic car rentals, and a wide variety of products/services for the enthusiast.” On certain designated days – such as the Cars & Coffee event held most recently on Saturday, July 18, 2015 – you can visit the physical location and see luxury cars, up close and in person.

DuPont 9We attended that event and had a chat with the organizers of the ten-year-strong show. Its success and popularity originally came through word-of-mouth advertising. While an event now typically draws in a few hundred cars, DuPont Registry doesn’t charge admission – not even for parking. They also give back to the community, allowing a local church to join them to sell coffee and doughnuts to the crowd.

DuPont 18Popularity of the events, organizers tell us, definitely has seasonal cycles. Fall and spring are busy times, while the winter and dead of summer are for diehards only. During more well-attended events, organizers have their work cut out for them. Not only do the local law enforcement need to be on board, but fans have to behave appropriately.

The good news: Cars & Coffee at DuPont has no end in sight. As long as the fans keep the cars on the road and the sheriff is on board, the show will go on.

More Cars & CoffeeDuPont 3

Across the country, Cars & Coffee monthly car meets have been popping up at an incredible rate. In fact, some popular events have even outgrown their venues, including one of the most highly acclaimed Saturday morning shows, located in Irvine, California. As the event kept growing, it outgrew its humble location in 2015, becoming too massive to remain a calm and fun-for-everyone event.DuPont 20

Cars & Coffee events offer a unique atmosphere that is addicting for car lovers who want to see the rare and eclectic – and to talk to the owners of these uncommon cars (and bikes!) who truly treasure them. One of the bigger events is the Amelia Island Concours d’Elegance.

The best part of one of these shows: meeting new people and hearing the story about a car, where it came from, where’s it been. Give someone a good cup of coffee and a few doughnuts, and you’ll have that person talking in no time.DuPont 14

Looking towards the future

Coming up this fall, the DuPont Registry Headquarters will host another type of event because, when Mr. DuPont wants more shows, his team will deliver. You can count on that.

Here’s a hint … just think cars, stars, and a show fit for the big screen.

Editor’s note: So what if your daily driver isn’t as glamorous as the ones shown above. You can still ensure it rides right and looks good with parts and tools from Advance Auto Parts. Buy online, pick up in-store in 30 minutes.

Does the Type of Gasoline You Use Really Matter?

gasoline pump photo

If you’re paying too much at the pump, read on as our Mechanic Next Store explores the mysteries behind gasoline pricing and octane ratings.

When it comes to gas for your vehicle, is it all the same? Is there a difference between the “name brands” of Exxon, Mobil, Shell versus the “grocery store gas” at Kroger or WalMart or even the less common “off-brand” names sold at discount stations with odd-sounding names that include “Kangaroo,” “Pure,” or “Liberty”?

And what about the different grades of gas available at starkly different prices. Call it what you will – regular, mid-grade, premium, 87, 89, 93, or even “V-Power” if you happen to be filling up at a Shell station. By choosing one fuel over another, are you risking damaging your engine in the interest of saving money?

Let’s start with the easy answer. Unless the station attendant is bringing your gas out in a metal bucket or dispensing it from a pump with a glass globe on top so you can see the “quality” or lack thereof, like they did at the earliest gas stations, there’s little difference in quality no matter where you buy gas. Gas quality today is regulated and legally required to contain certain levels of detergents, octane, ethanol and other ingredients. And while “name brand” gas might contain more engine-cleaning detergents, there’s a good chance that the gas found at “off-brand” stations was actually produced by the same name-brand manufacturers you know. Save some money and buy gas where it’s convenient for you and easiest on your wallet and comfort level.

The bigger, and age-old question and debate on most motorists’ minds is, “do I need to spend more money on a higher grade fuel, and if so, which one, and why?” There are generally three grades of unleaded gasoline available at nearly all U.S. gas stations, regardless of name, with the price per gallon rising in tandem with the fuel grade. Depending on what you drive, these grades matter.

To make an informed decision, you need to first understand what those numbers mean. The results might surprise you. Spoiler alert – a higher number doesn’t necessarily mean the gasoline supercharges your engine.

The three numbers in question are simply octane ratings, which mean nothing to most drivers unless they’re a chemical engineer, or work in the petroleum industry. When crude oil is refined (cracked) into gasoline and other byproducts, the end results are products composed of hydrocarbon chains of varying lengths. For example, methane has one carbon atom, propane has three, hexane six, and octane eight. Thanks to Mother Nature, it turns out that octane – technically iso-octane – with its eight carbon atoms and 13 hydrogen atoms, resists detonation really well, as compared to, say, heptane, which ignites fairly easily. An 87-octane rating means the gas is composed of 87 percent octane and 13 percent hexane and/or other ingredients. Pushing the “91” button at the pump delivers gas that’s 91 percent octane, and so forth. You get the picture.

Fascinating – but what’s this got to do with your engine, and possibly saving some dollars at the pump? Simply put – as the octane rating goes up, so too does the gasoline’s ability, when mixed with air in the engine’s cylinders, to withstand compression without spontaneously detonating or igniting. In gasoline engines, the air/fuel mixture inside the cylinder is supposed to ignite only when a small flame is sparked by – you guessed it – the spark plug. As that small flame gradually grows and spreads out within the cylinder, the air/fuel mixture should ignite in one detonation. Problems arise, mainly in the form of an audible “knock”, when more than one detonation occurs within the cylinder. And that “knocking” or “pinging,” or “pinking” if you’re in the U.K., can be more than just an annoyance and rob your engine of power – it can also destroy it, quickly or over time.

As that initial flame grows, pressure and heat within the cylinder rise. Under the right circumstances, those increases will cause the air/fuel mixture that hasn’t yet been reached by the flame to detonate, resulting in two detonations – one from the flame and a spontaneous one from the increased pressure and heat. The knocking sound results.

Most modern vehicles have knock sensors on the engine that can tell when a knock is about to occur and can adjust the spark’s timing just enough to prevent the premature explosion. A higher octane fuel is better able to withstand the increased pressure or compression, thus preventing spontaneous detonation.

Does your vehicle need higher octane?

But that doesn’t answer the question of which engines need higher octane fuel. It’s a question with several answers. For starters, high-performance engines need higher octane fuel. That’s because the engine’s designers engineered it to generate higher compression within the cylinder and increased power. Higher pressure and lower octane, however, isn’t a good match.

To help determine what octane rating your vehicle needs, start by looking in the owner’s manual. Other good sources are two lists in this article that specify which vehicles require premium gas and those for which it’s just a recommendation. For example, Acura’s MDX, RDX and RLX are all on the “premium-required” list, as are Audi’s A4 through A7, several BMW models, Chevy’s Camaro and Corvette, the Dodge Viper, and numerous other vehicle manufacturers and models. On the “premium-recommended” list are again Acuras and Audis, Ford’s Escape, Subaru’s WRX and several Volvos. High-performance engines that require a higher-octane fuel and don’t get it will deliver decreased power and performance.Gas prices photo

Still other drivers determine whether they need a higher octane fuel through experimentation. If the vehicle runs great on 87 with no knocking, pinging, or performance issues, and choosing the lower grade fuel doesn’t run afoul of any warranty requirements or specific manufacturer guidelines, why spend the extra money on a higher octane fuel?

Knocking or spontaneous detonation can be caused by other factors as well. For starters, the environment can be the culprit. Areas with high temperatures and low humidity can increase knocking and the need for higher octane. So too can vehicle age. Older vehicles can have a buildup of carbon within the cylinder, creating hot spots that lead to pre-ignition. These deposits can also decrease cylinder volume leading to higher pressures. Other culprits include a malfunctioning EGR system that increases cylinder temperature or an improper or malfunctioning spark plug. Increased load – like those that occur when towing or during steep uphill climbs – higher RPMs, or a malfunctioning cooling system that results in higher engine operating temperatures can also bring on the knocking.

Leaded gas and older vehicles

Many drivers will remember another choice available at the pump in addition to the three grades available today – leaded or unleaded fuel. Around the 1920s, a partnership between GM and ESSO, now Exxon, discovered that adding tetraethyl lead (TEL) to fuel helped raise the octane ratings above what they were listed at by increasing the compression ratio. Leaded fuel also came with the added benefit of helping protect soft valve seats, like those found in many 1970s-era vehicles and earlier.

During engine operation, heat from combustion gases causes valves to temporarily weld themselves to valve seats, if only for a tiny fraction of a second. Each time the weld between the two is broken, minute metal pieces from the soft valve seat are torn away, attaching to the valve. Over time, these deposits oxidize and further harden, inflicting damage on the valve seat as the valve continually hammers down. Lead in fuel helped prevent the two from welding, reducing valve seat recession or wear. Unfortunately, lead – which was spewing from the exhaust of millions of vehicles worldwide by that time – is bad for the environment and devastating to human health, which is why it was gradually phased out beginning in the 70s.

Fuel additives

That begs the question of what’s a 1970’s muscle-car owner to do to prevent damage in the absence of leaded fuel, short of spending a lot of money to install hardened valve seats or replace a cast-iron head with an alloy one? For starters, don’t overwork your engine, turn consistently high RPMs, or let her get too hot. And, consider adding a lead substitute with anti-wear properties to your gas tank.

For the rest of you, consider using one of the countless octane boosters available, most of which are designated as being safe for turbos, oxygen sensors and catalytic converters, if your vehicle needs it.

And remember two things. If you hear some knocking and there’s no one at your door, it might be time to switch to a higher octane fuel. On the other hand, if the vehicle manufacturer doesn’t specify high octane and there aren’t any performance issues, save some money by sticking with a lower octane fuel, and purchasing it where you want.

All About Karting Vehicles (some call them go karts!)

Go kart 2

Today’s go karts are anything but greasy kids stuff. Read on to discover what makes these these mechanically impressive machines tick.

Some people love go kart racing – simply called “karting” by the true blue fans – because of the competition. Others love it for the family atmosphere at events. Still others love it because of the vehicles themselves – and, if you’re a DIYer, you’ll probably want to know just how these racing machines are constructed.

Recreational participants sometimes construct their own vehicles, while competitive racers must purchase factory-made ones. It’s all about safety. Racers on big tracks reach speeds of up to 152 miles per hour in professional-grade karts that typically weigh 165 to 175 pounds (75 to 79 kilograms).

Here’s more…

Engines

“The TaG division,” says John Ferris, president of the World Karting Association, “is the most popular. TaG stands for ‘touch and go’ and its vehicles have an electric start, like a car, while the other divisions need an external starter, like Indy cars. TaG vehicles have water-cooled engines, while the rest have air-cooled ones.”

Typically, backyard / amusement park karts are powered by 4-stroke engines or electric motors, while racing karts use small 2-stroke or 4-stroke engines. “All classes of racing,” John says, “allow the owner to work on the engine – or to hire someone else to do so – by putting in new pistons or rings and the like. Some classes allow for rebuilding of engines that include modifications to make the kart go faster.”

The sport has evolved over the years and here is just one way in which that’s true. “Classes that allow modifications used to be the most popular,” John explains. “In these open classes, you could modify however you wanted – at least within certain limits. Local Saturday tracks, sometimes called outlaw tracks, still have those classes, but there is no tinkering in the big races. Those races are like NASCAR with strict specifications for engines.”

When people do modify engines, they typically take a factory built one and bring the specs up to the limits, perhaps by raising ports – or by lowering ports. “You can’t add extra ports,” John cautions, “because you need to use stock engines.”

More specifically:

  • 4-stroke engines are typically air-cooled, with about 5 to 20 HP. Manufacturers include Briggs & Stratton, Tecumseh, Kohler, Robin and Honda.
  • More powerful 4-stroke engines are manufactured by Yamaha, TKM, Biland and Aixro (Wankel), offering up 15 to 48 HP.
  • 2-stroke engines are built by WTP, Comer, IAME (Parilla, Komet), TM, Vortex, Titan, REFO, TKM, PRD, Yamaha and Rotax, ranging from about 8 HP for a single-cylinder 60 cc unit to more than 90 HP for a twin 250 cc.
  • The most popular classes use TaG 125 cc units, which are electronically limited to 16,000 RPM.

Suspension

Karts do not come with any sort of suspension system. In fact, shock absorbers and springs are banned from the vehicles, according to John. “Instead,” he says, “the frame of the vehicle itself serves as suspension. A kart’s chrome tubing creates spring and flex, allowing the vehicle to spring and come back.”

Chassis

Although the chassis needs to be flexible enough to serve as suspension, as mentioned above, it must also be stiff enough not to break. In general, a stiffer chassis is preferable for dry conditions, while a more flexible chassis is preferable in wet and/or other poor traction conditions.

To find which chassis – and accompanying engine – is appropriate for World Karting Association events, see the chart at the bottom of this page.

Transmission

Because karts do not have a differential, the chassis is designed so that the inside rear tire lifts off the ground when cornering. “Karts are intentionally designed this way for speed,” John says, “so the inside tire doesn’t slow you down when you race. You may not notice as the tire lifts when you corner, but it does.”

Tires

Tires and wheels are significantly smaller than on a typical car, with Bridgestone, Dunlop and Maxxis making tires, along with kart-specific manufacturers such as MG, MOJO and Vega. Just like with cars, there are different types of tires for varying weather conditions. On a dry track, slicks are appropriate. Slicks range from very soft compositions that provide maximum grip to much harder ones that are longer lasting but provide less grip.

Rain tires are used in wet weather, and are also known as “wets.” These are narrower tires than slicks and are not permitted in all racing classes. John points out that many organizations specify how soft your tires are allowed to be.

MiscellaneousGo Kart

More sophisticated karts contain monitoring systems that keep track of RPM, lap timing, number of laps, best lap, cooling system temperature, exhaust gas temperature, g-force (lateral and longitudinal acceleration), throttle position, steering wheel position, brake pressure and more.

DIY

If you’re interested in building your own kart for recreational karting, Popular Mechanics offers advice. This article shares how you can build your own kart for $689.15 in just one day, offering sites that provide the materials and resources that you’ll need. Remember that, if you’re interested in more serious racing, homemade karts are not permitted.

Mark your calendars: 46th Swigart Meet August 7-9, 2015

Swigart 2 If you’re looking for a place to display your antique or classic car and spend a weekend with like-minded people, consider adding the annual Swigart Meet in Huntingdon, Pennsylvania to your schedule. Not only will you see plenty of outstanding cars at the meet, but you can then go into the nearby museum to see even more incredible vehicles, including rare – and even unique – cars.

Prior Swigart Meets have featured the following cars:

  • 1925 Packard four-door sedan
  • 1968 Honda Dream motorcycle
  • 1979 Lincoln Continental Mark V Limousine (formerly owned by Conrad Hilton)
  • 1960 Austin Healey Sprite
  • 1976 Pontiac Trans-Am Coupe
  • 1999 Plymouth Prowler

Find photos and more information about the 2014 meet here. And, if you attend in 2015, be sure to visit the museum that co-sponsors the meet.

William E. Swigart, Jr. Automobile Museum

The National Association of Automobile Museums has only given out three Lifetime Achievement Awards: to Henry Ford, William F. Farrah (National Automobile Museum) and W. Emmett Swigart.

  1. Emmett Swigart may have been the first person to recognize the value in collecting old cars, first sharing his collection in 1920, after watching beat up vehicles being dismantled for parts. This was an era when many entrepreneurs tried their hand at car manufacturing, with typically small production runs – most of which haven’t been in production for a long time now.

He passed on his love of unique cars to his son, William E. Swigart, Jr., who opened the William E. Swigart, Jr. Automobile Museum in Huntingdon, Pennsylvania.

Swigart 1While at the museum

Billed as the oldest museum for automobiles, it contains rare cars, including these three one-of-a-kind treasures:

  • 1936 Duesenberg 12-cylinder Gentlemen Speedster with 160 hp; a Lycoming L-head, V-12 engine; 390.8 ci; and 3 speed manual transmission. Two of these cars were built, but one was lost in a fire. The one in the museum was previously owned by actor Jackie Coogan.
  • 1916 Scripps-Booth, a luxury vehicle built in Detroit; this was the year that Scripps-Booth merged with the Sterling Motor Company, with a goal to build 12,000 cars in just one year.
  • 1920 Carroll Six: one of the previous owners, Eric Johnson, used scrap airplane parts from a WWII PT19 Fairchild trainer engine to repair the vehicle; more about the Carroll Six later.

This is the only museum with two Preston Tucker vehicles, located side-by-side, including his hand built 1947 Tin Goose Prototype. Plus, this museum may have the largest license plate and radiator emblem collection in the country.

Overall, there are approximately 200 vehicles in the collection, with 35 to 40 on them on display at any one time. Other rare cars include:

  • 1930 Model J dual-cowl phaeton, a “straight-eight” with dual overhead cams and 265 hp
  • 1903 Curved Dash Oldsmobile, one of 3,924 of this model built in this year, the third year of production for the company
  • 1910 Winton Six Model 17-B, with 48.6 hp and a cost of $3,000 when brand new (more than $73,000 in today’s dollars)

Carroll SixCarroll Car 1

Advance Auto Parts did a bit of digging into the story behind the Carroll Six. Why? Because it was built by one of the 70 to 80 entrepreneurs who manufactured cars in the Cleveland area during the early 20th century – and because there is only one known example left in the world.

To that end, car historian Bob Kayle provided us with the January-March 1991 issue of The Bulb Horn, the publication of The Veteran Motor Car Club of America. Through this resource and a handful of others, we discovered that:

  • Charles F. Carroll, an attorney, successful advertising professional and inventor, announced his new car in Lorain, Ohio’s Times Herald on January 13, 1920.
  • He rented factory space, created blueprints, gathered car parts and persuaded wealthy local stockholders to invest in his dream.
  • “Two bodies will be furnished, one a close coupled five passenger touring car and the other a roadster, and will be finished in either Carroll green or Burgundy red. The wheelbase is 131” and it will have an aluminum body upholstered in leather. The six-cylinder engine develops 48 hp and has enclosed overhead valves. Full equipment includes six disc wheels, Fisk cord tires, permanent type top, and trunk with a built-in rack.”
  • The roadster never came into being and the wheelbase was scaled down to 128”.

Distribution was a big problem for early car manufacturers, but Carroll quickly secured a partner in San Francisco, Fred W. Hauger, who planned to sell this car in 11 states, plus the Hawaiian Islands.

One hundred and six cars were scheduled for 1920, although it’s unlikely that the production goal for this “attractive and even a bit racy” vehicle was reached. The car had a:

  • radiator that was set back seven and a half inches from the front axle
  • body, hood and fenders that were “pleasingly curved”
  • swept-back windshield that gave it a slightly futuristic look

The car was not cheap ($3,895 or more than $45,000 in today’s dollars) but it did come with leather-covered steel top, side curtains, long running boards with dual side-mount spare tires, Bijur starting and lighting, and a K.W. ignition system.

Some Carroll cars were allegedly ruined when they were shipped to California without antifreeze. When the weather turned cold, the engines were ruined, a serious financial blow to the company. By May 1922, the company was out of money and one of the investors was said to help himself to four cars, plus a partially built one, plus some parts as his self-determined repayment. Although there are rumors of four Carroll cars still being in existence, only the one at the Swigart museum is a certainty.

Crucial Cars: Chevy Tahoe

Red Chevy Tahoe 1

From timeless icons to everyday essentials, Crucial Cars examines the vehicles we can’t live without.

In this installment, the Mechanic Next Door takes on the feature-rich Chevy Tahoe.

Kelly Blue Book voted the 2015 Chevrolet Tahoe The Best Buy of the Year among full-size SUVs. ALG awarded it first place in the full-size SUV category. Car and Driver named it the Editors Choice in Full-Size Crossovers/SUVs, and the Texas Auto Writers Association selected Tahoe as the Full-Size SUV of Texas (doesn’t it go without saying that everything in Texas is full-size?) at the Texas Truck Rodeo.

The Tahoe has impressive numbers to go along with those awards and accolades. Tahoe sales increased 88 percent in January of this year compared to the same time period last year, and in the large SUV category, Tahoe sales year-to-date in April were nearly double that of its closest competitor – second-place Chevy Suburban.

Clearly, the Chrvrolet Tahoe has what drivers want, especially when gas prices are low.

Tahoe was born in 1994 for the ’95 model year, springing from the Chevrolet Blazer and capturing MotorTrend’s Truck of the Year Award in just its second year. Shorter than its Suburban brother, Tahoe shared until 2000 the similar GMT400-series platform with Suburban, as did the Yukon, Escalade, Blazer and C/K trucks.

In the 20 years since Tahoe’s debut, consumer demands and tastes have evolved, as has vehicle technology – so much so that today’s Tahoe bears little resemblance to its first predecessor, other than its name.

A quick look inside Tahoe’s interior leaves little doubt what’s front and center on consumers’ wants and needs list, and it’s not just cup holders. We can’t live without our electronics, and Tahoe’s amenities ensure we don’t have to.

Available 4G LTE Wi-Fi Technology accommodates the simultaneous connection of up to seven devices so every passenger remains connected, even on the road. All those devices need power, which they’ll have no trouble finding, thanks to 13 charging stations (airport waiting area planners, take note) as well as the availability of wireless charging and a three-prong, 110-volt outlet for laptops and larger devices. Six of those 13 charging stations are USB ports and there’s Bluetooth capability that can also attach up to seven devices with Chevy’s MyLink system.

Controlling MyLink is accomplished with the swipe of a finger on an eight-inch, color touch screen that features customizable icon locations. Hidden behind the touch screen is a secret compartment for storing small items, accessible only by entering a password on the screen.

Yes, Tahoe has class and style, right down to its instrument cluster, which Chevy describes as being “designed after high-end watches.”

When Tahoe drivers need to haul something other than precious human cargo, there are 94.7 cubic feet of cargo space, and second and third-row seats that fold flat. Chevy also boasts that Tahoe has “the fastest power-release second-row and power-folding third-row seats of any competitor.” Because that’s important when you’re in a big hurry to…..remove or fold your seats?White Chevy Tahoe 1

In addition to a hands-free liftgate that opens with a gentle kicking motion thanks to a sensor hidden under the rear bumper, Tahoe also features keyless entry as well as starting, bringing the engine to life with just the push of a button. Passengers will have difficulty hearing that engine, or any other external noise for that matter, as Chevy claims this is “the quietest Tahoe ever.” Sound-dampening material has been added pretty much everywhere, including in the engine compartment, wheel liners, dash and floor, and there’s an “acoustic-laminated windshield” along with triple-sealed inlaid doors.

All this peace and quiet and style sit atop available 22-inch aluminum wheels with premium paint and chrome inserts, or 20 inchers or even 18’s on the LS and LT models.

Stepping up into a Tahoe – particularly one riding on 22’s – is made easier with the by retractable side assist steps with perimeter lighting. While that lighting is a nice touch, the heavy-duty illumination comes in the form of projector-beam headlamps and rear LED tail lamps that really light up the night, with high-intensity discharge (HID) lamps available on the LTZ model.

Even with gas prices being low, fuel economy is still top of mind for most drivers, and Tahoe delivers about what you’d expect for a vehicle of this size – EPA Estimated Fuel Economy of 16 MPG around town and 23 or 22 – depending if you’re piloting the two- or four-wheel drive version, respectively – on the open road.

That 26-gallon fuel tank is feeding a 5.3-liter EcoTech3 V-8 that features active fuel management which takes four cylinders offline when their power isn’t needed, direct injection for more power and fuel efficiency with reduced emissions, and variable valve timing for maximum power and efficiency. All this engine technology churns out an impressive 355 HP and 383 lb-ft torque that are capable of towing 8,500 lbs.

And, let’s not forget what’s most important – safety. Seven airbags, collision alerts, lane departure warnings, automatic front braking, side-blind zone alert, rear cross traffic alert, rear park assist, rear-vision camera, and a theft-protection package help protect and prevent.

Available in three models, an LS, LT, and LTZ, Chevy calls it, “the most advanced Tahoe ever,” and they’re not kidding. But first you’ll have to decide on what you need and what you can afford. MSRP is $46,300 and there is a list of add-on accessories – 58 to be exact – in nine categories covering everything from interior or exterior cargo management to electronics to security and protection.

Tahoe’s all grown up and has class and style, making it a perfect match for drivers with similar qualities.

Car customization photoIf you’re looking for an inexpensive way to customize your car, then consider headlight, turn signal and taillight tinting. You can add a touch of personalization quickly, as long as you have a few basic materials, including the tinted film – and a steady hand.

But – and we can’t stress this enough – be sure to check with your state laws before adding any sort of film to your lights! And, the reality is that, if you travel to another state in this vehicle, you may have to face some challenges with law enforcement there if their laws – or enforcement of them – differ.

Here is a quick look at how to tint your headlights using vinyl from a roll:

Meanwhile, here are easy-to-follow instructions that use:
• soap
• paper towels
• heat gun
• squeegee
• spray bottle
• tinting film
• craft knife

Although tinting of your headlights, turn signals and taillights is inexpensive compared to many other customization options, it’s important to get quality vinyl – and that it’s transparent so that the light output is not dulled, which can be dangerous. Be cautious of spray products that create cool looks but produce dulled lighting that makes road driving hazardous.

Window tinting laws – can you do it or not?

There is a website specifically dedicated to sharing tinting laws by state, with the following cautions:

Every state has different laws, rules, regulations and guidelines and we are offering concise data for legally allowed window darkness and reflection for each of the 50 states. While we provide generic state tint law information, note that every district or county may have its own specific restrictions, exemptions or regulations. You should verify our information yourself with your local DMV or other law enforcement authorities.”

As an example, here are applicable laws for sedans in California:

Tint darkness for sedans:

  • Windshield: Non-reflective tint is allowed on the top 4 inches of the windshield.
  • Front Side windows: Must allow more than 70% of light in.
  • Back Side windows: Any darkness can be used.
  • Rear Window: Any darkness can be used.

Tint reflection for sedans:

  • Front Side windows: Must not be more reflective than a standard window.
  • Back Side windows: Must not be more reflective than a standard window
  • Side Mirrors: Dual side mirrors are required if the rear window is tinted.
  • Restricted Colors: California tint laws do not permit using red, amber or blue tint colors.
  • Certificates: Manufacturers of film do need to certify the film they sell in the state and the driver is required to have the certificate in his/her possession.
  • Stickers: State law does require a certificate or a sticker from the installing company and the manufacturer’s name and address.
  • Medical Exceptions: California law doesn’t allow any medical exemptions that would allow you use special tint.

Although California does not provide for any medical exceptions, some states do for people with sun allergies or other skin conditions. Different laws apply in California for vans and SUVs. And, here is information about window tinting in California directly from their DMV. We recommend that you look at the DMV information pertinent to your state before you begin.

Top reasons to tint your car windows

First of all, it can look really cool! We don’t need any experts to verify that for us. As for the rest of the benefits listed for window tints, keep in mind that many people who are knowledgeable about tinting also sell the product and we have not found independent studies that verify these claims. Many of them, of course, just make good sense.

• Sun glare can be dangerous. Yes, you can wear sunglasses, but you can lose them or break them. Tinting helps you to drive more safely without needing another glare-cutting accessory.

• Tinting provides more privacy. This means that people can’t readily see what you have in your car, helpful when you’ve gone shopping – or accidentally left your wallet or purse or cell phone, laptop or other in-demand device inside. Most people are honest, sure, and wouldn’t think of breaking in to steal your belongings, but the tinting will help protect you from people who might.

• Tinting provides protection to your upholstery, keeping your car interior cool enough to help prevent warping, fading and cracking. Plus, it feels cooler and more comfortable when you’re sitting on it.

• These treatments make your windows more shatterproof. This can help protect you and your passengers in an accident as the tint can keep pieces of broken glass together and prevent them from getting into your eyes or slicing your skin. Window tinting can save you money if an object crashes into one of your windows, for the same reason (tinting holding pieces of glass together).

You can stay cool! You can reduce the heat inside your car significantly with tinting. A cooler interior means that you’ll have less need of your air conditioning – and less air conditioning means that you’ll use less gasoline.

• You can reduce UV rays with quality car tinting. Prolonged exposure to UV rays have been associated with skin damage, up to and including skin cancer. We have not seen any scientific studies that show a reduction in risk by using window tints, but common sense says it could have a helpful effect. Window tinting comes in a variety of variable light transmissions (VLTs) and, the smaller the number, the darker the tint – and the smaller amounts of light that is let through.

Choosing the right tint for your windows

Typical VLT choices – from least tinted to most – are 70%, 50%, 35%, 25% and 5%. As with all products, there are higher quality films and lesser quality ones. Higher quality ones are said to fade and crack less often. You can purchase an auto tinting kit with pre-cut pieces to fit your windows precisely. Or, you can purchase the tint material in a roll and cut the film yourself.

Why You Should Keep Your Engine Clean

Dirty car engine photo

Our Mechanic Next Door runs down the top six reasons–and foolproof steps–for cleaning your vehicle’s engine.

If you’ve ever purchased a new or used vehicle from a dealer or prepped for a car show, you know just how clean an engine compartment can look. The metal gleams, the black hoses glisten, and you can touch any surface and not come away covered in dirt, grease or oil. Conversely, every driver knows that it doesn’t stay that way long as things get nasty under there in a hurry – a fact we’re reminded of every time the hood’s popped to check fluids, do some work, or investigate a disturbing new noise, vibration, or smell.

Drivers clean their vehicles’ interiors and exteriors, but by and large tend to ignore the engine compartment, allowing grit and grime to accumulate over the years and miles. Whether you don’t clean under there because you don’t know how and are afraid you’ll damage something, or you’re a seasoned do-it-yourselfer but just don’t think it’s important, consider these thoughts and tips on engine cleaning.

Why do it?

Sure, a clean engine looks great, but that’s just one of the reasons for tackling this project. Here are some reasons you may not have thought of for cleaning your engine and engine compartment:

  • It’s easier to spot potential trouble before it becomes a major problem. If your engine is filthy, you’re not going to know if that small fluid leak has been there forever, or if it just appeared. Clean engines make leaks, cracks and other problems easier to spot.
  • Remove road salt and debris that can lead to corrosion if they’re allowed to accumulate.
  • Remove debris that can cause hot spots to form on the engine and its components, shortening their lives.
  • Prevent the buildup of combustible materials, such as leaves or oil, that are fire hazards on the road and in the garage.
  • A clean engine is more enjoyable to work on and look at.
  • A vehicle with a clean engine and engine compartment has a higher resale value.

Make it shine.

Ask ten different DIYers how to clean an engine and you’ll get 10 different answers. It’s not rocket science, but it’s also not something you should dive into without possessing some knowledge. Back in the day, the preferred method of cleaning an engine was to steam clean it. Cheap, easy, and it got the job done. Times change, as do engines, and steam cleaning isn’t the best option any longer because of the sensitive electronics in the engine compartment. Fortunately, there’s an alternative today – engine cleaners.

First, browse the various engine cleaning and degreasing products available. There’s water-based, solvent-based, gel, foam, spray bottles, aerosol cans – you name it. I prefer a solvent-based cleaner because it cuts through grease and grime better than a water-based one, which translates to less effort and elbow grease for me trying to scrub away stubborn dirt. I also migrate toward gel-based engine cleaners because I like the way they stick better to vertical surfaces, giving the cleaner’s scrubbing action more time to work on the surface, and me more time to do something else.

How engine cleaners work is a mystery to me, mainly because I’m not a chemist. The Material Safety Data Sheet (MSDS) for Gunk Foamy Engine Brite Cleaner includes propane, 2-butoxyethanol, aromatic petroluem naptha, isobutene, and petroleum base oil as ingredients. I don’t know what they do, except work well, but I imagine the solvents and other ingredients break down the grease and grime and reduce its surface tension, making it easier to wash away.

In addition to choosing a cleaner/degreaser, you’ll also want to pick up a drip pan and some absorbent pads. Why? A lot of oil and other chemicals will be rolling off your engine when you clean it and this hazardous cocktail shouldn’t be going onto your driveway, into a storm water drain, or seeping throughout the ground. Instead, capture the dirty fluids on the pads and drip pan, allow the pads to sit in the sun until the water evaporates, and then find a local recycling center that accepts both the used pads and the oily water from the drip tray.

Once you have all your supplies, use an air compressor or can of compressed air to first blow away any loose debris that may have accumulated under the hood.

Next, start the vehicle and let the engine warm up – but just a little. You want it warm to help break up the grease when the cleaner is applied, but not so hot that you can’t touch it and that it presents a fire danger when sprayed with a solvent or when oil and grease start moving around. Also, a hot engine sprayed with cold water is a sure-fire way to damage an engine and other vehicle parts.

Once it’s warmed up and the engine is off, wrap all visible electronic connections and components in plastic wrap or plastic bags to prevent water from damaging them. Cover the alternator and all filters and the air intake as well.

Position the drip pan and absorbent pads under the engine, then apply the engine cleaner – following the manufacturer’s instructions – and wait for the magic to happen. While the cleaner is working, look for any areas that have a lot of grease or dirt and scrub those spots with a plastic-bristle brush or rag.

Once the cleaner has been on there for the recommended period of time, rinse it and the dirt off gently. Engine cleaning is not a job where you want to use a car wash hose or home pressure cleaner because the water pressure is too high and could force moisture into sensitive engine parts. Instead, use a gentle spray from a garden hose, being sure to avoid electronic components as much as possible. Once the rinse is complete, the compressed air will come in handy again to blow any water out of crevices where it may have accumulated.

When you’re satisfied with the appearance, remove the plastic coverings applied earlier, start the engine and let it reach operating temperature to help evaporate any remaining water.

When the engine has cooled, apply a rubber or vinyl protectant to hoses and plastic components. Then, step back and admire your very clean, very shiny, and very satisfying engine bay, and ask yourself why you waited so long to clean your engine.

Mudding Anyone?

Truck mudding photoOur resident Gearhead gets down and dirty with the fine art of Mudding.

Remember when you were a little kid and the idea of playing in the mud outside after it rained got you hyped? Pushing your toy cars and trucks through the mud puddles while you did your best to enunciate the sound of a beefed-up engine was one of life’s simple joys. Well, now you’re a grown-up with a rugged four-wheel-drive rig and maybe you want to kick up some summer mud, albeit on a much grander and exciting scale. Here’s a video that gives you a taste of what a blast this sub-category of off-roading can be.

Jeep_Wrangler  photoChoose your weapon
To probably nobody’s surprise, the most popular mud tamer is the modern-day Jeep Wrangler and its very similar old-school forebears, Jeep’s CJ-5 and CJ-7. Compact dimensions, plenty of ground clearance, stout four-wheel-drive components and room in the wheel wells for large off-road tires are key reasons these iconic Jeeps reign supreme.

But they are far from the only good choices. Older Toyota Land Cruisers (the more basic four-door SUV styles as well as the Jeep-like FJ40) are very capable and durable rigs, as are the first- and second-generation Ford Broncos. Of course, 4WD pickup trucks are solid picks too, though the massive, full-size ones can sometimes prove too bulky in off-road environments with narrow trails. As such, we favor compact, more maneuverable pickups such as the Ford Ranger, Nissan Frontier and Toyota Tacoma. One might also consider a Land Rover Defender, though aces off road, they tend to be rather pricey.1988_Toyota_Land_Cruiser photo

Mudding 101
Depending on the scenario, simply popping your truck into 4WD and driving on through the muck as if you’re on pavement may not be sufficient. As with any type of challenge, there are proper techniques that separate the hackers from those that know what they’re doing. As such, thanks to the pros at off-road.com, fourwheeler.com and allstate.com, we’ve come up with a six-pack of tips to make sure that you move through the mud.

1) Don’t go it alone. Having at least one other person with a truck and recovery gear (such as a powerful winch) provides peace of mind, as well as a helping hand (and truck) should you get stuck.

2) Air down your tires. Lowering your tires’ pressure increases surface area and allows the tires to flex and grab traction better than when they’re fully-aired up for on-road use. Dropping down to 18 to 20 psi should be about right.

3) If it looks like a rather deep mud puddle / bog you’re attempting to negotiate, you might want to hop out and go on recon first. Grab a long stick and check it out on foot, poking the stick in various spots to get an idea of the mud’s consistency, its depth and if there are any large rocks or tree roots lying below in wait.

4) Take the proper line. If others are also having fun in the muddy playground, watch and take note of the line they’re taking as they work their way through. Usually going straight is best, but there may be some obstructions or stickier points that may dictate using a different, more traction-friendly line that somebody else has demonstrated.

5) If your vehicle has a low range, then start out in 4WD low. This will obviously maximize your traction and torque at the low speeds you’ll be using to make your way through the mud.

6) Take it easy. Throwing up 15-foot high rooster tails of muddy water at higher speed may look cool in commercials, but you could lose control and end up doing some damage or stalling out your engine. It’s slow and steady that wins this race. As the experts say and as with other types of off-roading, you should go as slow as possible but as fast as necessary to keep moving forward. Momentum, not speed, is your best friend here.

So you’ve discovered that you really dig playing in the mud. Fortunately, so do a lot of other off-road enthusiasts. Reading the various online forums for tips on where to go, how to set up your vehicle and how to improve your skills will help you enjoy your mucked up adventures even more. We suggest also checking out enthusiast sites such as mudtrails.com and offroadworld.net, which are also great for finding new friends that share this dirty passion.

Editor’s note: After you’ve gotten your fill of summer mudding, be sure to hit up Advance Auto Parts for a wide selection of wash and wax products.

 

Crucial Cars: Eagle Talon

1990 eagle talon tsi photoFrom timeless icons to everyday essentials, Crucial Cars examines the vehicles we can’t live without.

In this installment, Street Talk puts the spotlight on a rare but desirable bird in the sport compact segment – the Eagle Talon

One of a set of automotive triplets, the Eagle Talon is a rather rare bird in the sport compact car arena. Indeed, can you remember the last time you saw an Eagle Talon flying down the road? Yet this product of American and Japanese parents was one of the more interesting choices in its segment. Along with its aggressive, head-turning styling it offered available turbocharged power and all-wheel drive, the latter two features giving it a wheel or two up on the more popular kids in this class, the Honda Civic, Acura Integra and Nissan 240 SX.

The Eagle has hatched
Debuting for 1990 along with its Plymouth Laser and Mitsubishi Eclipse triplet siblings, the Eagle Talon was a product of a joint venture between Chrysler and Mitsubishi. All built in the U.S. at the “Diamond Star Motors” plant located in Normal, Illinois, these three cars shared similar sporty hatchback styling and Mitsubishi mechanicals. The base Eagle Talon came with a 2.0-liter, 16-valve four with 135 horsepower, while the TSi and TSi AWD versions packed a turbocharged 2.0-liter sporting 190 and 195 horses, respectively. Transmission choices consisted of a five-speed manual and four-speed automatic. Initially at least, unlike the Laser and Eclipse, the Talon didn’t sully its image with a price-leading, 92-hp stripper version. With 135 hp, even that base Talon provided peppy performance, but we know you’re probably thinking: “Yeah, that’s great, but tell me about the turbo!”

In 1990, squeezing nearly 200 horsepower from a four-cylinder turbocharged engine was big news. And thanks to the stout low- and mid-range grunt that a turbo provides, this meant blowing off less-muscular rivals from Honda, Toyota and Nissan was a breeze. Capable of sprinting to 60 mph in less than 7 seconds and running down the quarter mile in the low-15-second range, a Talon TSi was a genuine thrill ride back in the early ‘90s.1993 eagle talon tsi photo

Offering all-wheel drive to more effectively put that power to the pavement provided an edge in handling, especially in foul weather conditions. The AWD version of the TSi also featured a more sophisticated rear suspension (multi-link versus torsion beam) as well as limited-slip center and rear differentials. Outfitted with a set of Bridgestone Blizzaks and a ski rack, a Talon TSi AWD was a skier’s or snowboarder’s dream.

Changes from 1990 through 1994 were mostly minimal. Notable highlights included, for 1992, slightly revised front- and rear-end styling and a switch from pop-up headlights to exposed units. The following year saw the debut of a declawed Talon. Dubbed the DL, this downgraded version shared its 92-hp engine and sparse standard features list with its entry-level Diamond Star siblings. The previous “base” Talon essentially continued as a new “ES” trim level.

Eagle Talon Version 2.0
As with the Eclipse, the Talon was redesigned for 1995 (the Laser was dropped after 1994). The two cars looked even more similar than before. One might argue that the Talon had more handsome styling, with a larger set of tail lights that helped minimize the heavy, “loaded diaper” rear bumper look of its Mitsu relative.

More importantly, performance was boosted via a pair of more powerful engines. Seen in the new entry-level “ESi” trim, the 2.0-liter non-turbo four now made 140 horsepower, while the turbocharged versions seen in the TSi and TSi AWD made 210 hp (205 with the automatic transmission). As such, acceleration times were a few tenths or so quicker, meaning a TSi AWD could hit 60 in about 6.3 seconds and rip through the quarter mile in the high 14-second range.

1995 eagle talon tsi photoSadly, the Eagle Talon, and indeed the Eagle brand itself, would soar no more after 1998, having been discontinued after that model year. The biggest changes for these second-generation models took place for 1997, when once again Eagle debuted a stripped-out base model that deleted the ESi’s rear spoiler, audio system and intermittent wipers. Thankfully, this entry-level version did not substitute a weaker engine as it had in the past. That year also saw rear drum brakes replace the previously standard rear discs in non-turbo models, while the TSi AWD version got larger (17-inch versus previous 16-inch) alloy wheels. A larger front badge and rear spoiler are the more notable visual clues to these later second-gen Talons.

Endangered species
Should you be a fan of these exciting Eagles and want to capture one, you’ll likely find that task fairly difficult given that they were last produced nearly two decades ago. Still, that doesn’t mean impossible. Checking out the enthusiasts sites, such as DSMtalk and DSMtuners can provide a wealth of information, such as the most effective and economical mods, as well as classified ads for the cars themselves. And there’s always craigslist, eBay and bringatrailer.com, where your chances of finding an unmodified example are likely much greater than doing so on the dedicated sites.
