Memphis Auto Repair

When your experienced Allen's Automotive Center technician changes your oil, he will also inspect your air filter. You shouldn't need a new air filter at every oil change, but you will need to change it regularly. Heed your technician's auto advice if they tell you to change your air filter.An air filter does what its name implies: it filters stuff out of the air. Air is drawn into your engine through the filter because your engine needs air to burn fuel. If the filter weren't there, a lot of dust and debris would come into the vehicle engine with the air when you are driving around Memphis. That dust and debris would get hot, burn and produce all kinds of ash and gumminess that would eventually clog up your engine. Drop in an air filter and voilá! Problem solved. But air filters themselves get clogged up with all the junk they clean out of the Memphis air. This doesn't allow the junk into the vehicle engine, but it d ... read more

Would you be surprised to learn that about half of the passenger cars in Europe have diesel engines? You might also be surprised to learn that most manufacturers produce a variety of diesel-fueled cars for purchase abroad.Diesel-fueled vehicles haven't been as popular in the North American markets like Tennessee. But that won't be true for long. North Americans are seeing a lot more diesel-fueled vehicles on the road. And we're not talking about buses and trucks. These vehicles will be passenger cars, pick-ups and SUV's.There are two reasons for this. The first is a recent change in environmental laws that have upgraded emissions standards for diesel fuel in North America. Diesel fuel in North America used to have higher sulfur content than European fuel, meaning that it was a dirtier fuel to burn. That was okay for larger vehicles, but the lighter-weight engines in passenger vehicles just couldn't tolerate it.But that high sulfur content is now a thing of the pa ... read more

Memphis area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.

Now Memphis drivers can't always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle's perspective. What kind of roads will you be traveling – winding Tennessee byways? Purple mountain majesties or fruited plains? What weather conditions are you likely to encounter? How far will you travel each day? How much weight will you be hauling – passengers and luggage? Pulling a trailer, roof top carrier or ATVs? Will it be dusty? Prepared with answers to these questions, you can schedule a trip inspection at Allen's Automotive Center in Memphis to help you

Memphis area residents may remember when the U.S. government's “Cash for Clunkers” program made a splash on the news scene. People were offered incentives to trade in old vehicles for new, in the interest of better and improved air quality from reduced emissions.But a lot of Memphis drivers want to hang onto their old clunkers. They're dependable and they're paid for. Owners would love to see the odometers on those vehicles turn past 200,000 miles (320,000 km), as long as the repair bills don't get too expensive.There are a lot of vehicles on Tennessee roads that have run past the 200,000 mile (320,000 km) odometer reading. Is there something that their owners are doing that keeps these vehicles on the road? Or did they just win the “lemon lottery,” and luck out by getting a particularly good vehicle? Not surprisingly, most of these owners have something in common. They never skip an oil change. Can keeping a vehicle on the road for ... read more

Have you ever seen a ballet performance? Have you wondered how all of those dancers manage to travel all over the stage jumping and twirling and never crash into each other? That's the job of a choreographer.Our auto engines are also highly choreographed. Pistons travel up and down inside cylinders. Valves at the tops of the cylinders open to let air and fuel in or exhaust out. These valves have to open and close at precisely the right time or the engine will run poorly if at all. The movement of the valves and pistons must be in harmony with each other. This choreography is the job of the timing belt or timing chain.Timing belts, or chains, rotate the shafts that control the opening and closing of the valves. Timing chains are metal and durable enough that they may never need to be replaced.Most vehicles, however, use a timing belt. Timing belts are tough and flexible, and considering the work they do, they last a long time for Memphis auto owners . But they do wear out. If they ... read more

For those of you in Memphis, Tennessee who pay attention to these things, you may have been hearing about the new direct injection engines and want to learn more about them. Some deliver the power of a V8 with the economy of a V6.For example, in one family of engines the conventional V6 makes about 250 horsepower. The direct injection version of the same engine makes over 300 horsepower and gets essentially the same fuel economy. The turbocharged version makes over 350 horsepower.So what are the differences from a conventional engine?The core difference is in the fuel injection system. The system most vehicles use now is called a port injection system. The fuel injector squirts fuel into a port just outside the cylinder where it's then drawn into the engine with the air.With a direct injection system, the injector squirts the fuel directly into the cylinder. The gain in power and economy come because fuel injected directly into the cyli ... read more

Hello Memphis, let's talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Memphis folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.Pre-1963, gasoline engines had a hose that let the  fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you i ... read more

When Memphis drivers think about preventive maintenance, what usually comes to mind is oil, fluids and brakes. We don't generally think about our shocks or struts, but these auto parts keep our tires on the road.Memphis drivers don't think about shocks as often as oil changes because shocks and struts last a long time and wear out slowly. They don't need to be checked as often as our brake pads or air filters. By the time your shocks have 50,000 miles (80,000 kilometers) on them, their performance will have noticeable degraded. If you want to restore the handling and ride designed for your vehicle, try replacing your shocks and struts.Of course, if you drive off-road around Memphis, carry heavy loads, tow a trailer or put in a lot of mileage on poor driving surfaces, your shocks or struts will wear out more quickly. You'll need to replace them more often or upgrade to better shocks.Your suspension system uses springs and shocks to absorb the “shocks” and vib ... read more

Most Memphis drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Memphis vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, ca ... read more
