Don't you hate it when you hear that squeal from under the hood when you're zipping down a busy MEMPHIS road? It usually means there is a problem with the serpentine belt. The serpentine belt powers a lot of engine accessories. It runs the alternator - which charges the battery; the water pump - which cools the engine; the air conditioning and the power steering pump. All are pretty important parts. It is called a serpentine belt because it snakes around a bunch of engine components. Serpentine belts are amazingly tough. They can last for years and go long distances. Like all moving parts, however, they eventually wear out. If your belt breaks while you are driving around MEMPHIS, everything will come to a halt within minutes. You need to stop the vehicle immediately or it will overheat, potentially causing engine damage. You can be sure that it won't happen at a convenient time or place. (As if there was a convenient time or place!) You might even need to get your veh ... read more

Modern vehicles in and around MEMPHIS run on 12 volt electrical systems. 12 volts is enough to get the job done for MEMPHIS drivers without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks windows and sun roofs. And then us TN drivers have all the power outlets for our cell phones, computers and DVD players.We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off.Fortunately, battery technology has given MEMPHIS drivers resilient batteries that are able to meet these strenuous requirements. But the fact is, batteries just wear out over t ... read more

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at Winchester Tire & Alignment. At high speeds on TN freeways, the pressure can build up to the point that gaskets and seals start to leak. Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.This is much better for ai ... read more

Ever heard the sad tale of a staggeringly steep repair bill from a broken timing belt? Bad news. Let's take a lesson from their woes and remember to think about our timing belt.First, let's review what a timing belt does. The top part of the engine over the cylinders is called the cylinder head. The head contains the valves. There's at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two will open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves - that's 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It's called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything's in sync.The timing belt is a toothed rubber belt. But some vehicles use ... read more
