Seems like these days, we're hearing about more and more electric or hybrid vehicles. Keep in mind that conventional gasoline internal combustion vehicles have important electrical components, too, and it's important to make sure they're operating at their peak. In a vehicle with a gasoline engine, the part that keeps the battery charged is the alternator. It converts the mechanical energy created by the engine into electrical power. To do that, a shaft in the alternator has a pulley on one end that's driven by a belt that is turned by the engine. A series of magnets then spins around coiled wires and it creates alternating current, or electricity. Your vehicle uses that to charge the battery that, in turn, keeps other electrical components in your vehicle working. Here are a few signs that the alternator isn't doing its job right. The battery keeps going dead, your instrument panel's battery light is on (it looks like a rectangle with a - and + inside and ... read more

Driving along, your exhaust system's rumbling so loud that people turn and stare at you pass by. You're wondering when the police are going to pull you over for illegal noise. Your mind immediately thinks, aha! A broken muffler. Well, your exhaust system is composed of many more parts than just a muffler. Your engine makes power because of thousands of tiny explosions from detonating fuel. Those explosions make a racket, so engineers came up with a system that acoustically dampens that sound in addition to getting rid of harmful exhaust. In the engine is the exhaust manifold that looks like several pipes that join up into one pipe. It directs exhaust to the catalytic converter. The catalytic converter converts harmful gases into less harmful gases using certain chemical reactions. Then comes the muffler that has baffles inside to quiet the sounds of your engine noise. Finally: the tailpipe. All of those pipes and parts are joined together by cl ... read more

When the weather turns cold, it's nice to crank up the furnace and enjoy the heat. But if your home's furnace doesn't work, it's not too comfortable. Same goes with your vehicle. When the heater's not working, things can get miserable. It could also signal some major problems, which we'll discuss later. A vehicle's heating system is fairly complicated. It's made up of several parts, including a blower motor/fan, a heater core and some mechanical and electrical components. In basic terms, a vehicle's engine warms up coolant which is then sent to the heater core (which is kind of like a small radiator) behind the dash. That blower motor sends cold air through the heater core which heats up the air. Voila! Heat. Diagnosing problems in this system takes a trained mechanic because of the different possible issues. Your heater core may need replacing; they are sometimes in tight spots and may be difficult to work on. Another possible problem could be a defective thermostat, which regulates h ... read more

Winter and freezing temperatures present challenges for different parts of your vehicles. For example, winter tires give you better traction on snow. But some parts of your vehicle that may need special attention for winter are your windshield wipers. You may have found yourself in the middle of a snowstorm when your windshield wipers are doing nothing but streaking slush that ices up on contact on the glass. Now you're more blind than you were before! Obviously being able to see during a snowy or icy winter event is important for the safe operation of any vehicle. So keeping your windshield and rear window clean can go a long way to guarantee you can see your surroundings. Let's start with the wipers. Blades that are good for hot weather may not be robust enough for freezing weather. You can buy special winter wiper blades that stay flexible during sub-zero temperatures. The stiffer frames that hold them have a rubber covering that prevents ice and ... read more

There's lots of good information to read in books and online. You might not know that you can also "read" your tires and learn a lot about what shape they're in and if they are in need of attention. It's important to know how your tires are doing because a tire failure can be very dangerous to you, your passengers and others on the road near you. You read your tire by looking at the surface that rides on the road, where the tread is. Check out the outer and inner edges. If you notice there's more wear on the inner or outer edge than on the rest of the tread, your vehicle could be out of alignment. Wear on an inner or outer edge could mean your wheels are leaning too much to one side. When you see this, visit our service center soon to have the alignment checked. What about if both edges are worn? That could be a sign that you don't have enough air in that tire. In an underinflated tire, the middle is not contacting the road surface as much as the edg ... read more

You may notice that when you get your vehicle's oil changed, your service adviser may recommend that you have your tires rotated at the same time. The reasons are simple. That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road. There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns. For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern. The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front. For all-wheel and four-wheel drive vehicles, use the X pattern. The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front. For front-wheel dri ... read more

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most. Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails. It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon). That makes it hotter, so it then goes through a condenser that cools it off. Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator. That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day. Of all these parts, one that does a lot of work is the compressor. It has to compress that refrigerant and circulate it through the system. It turns on and off several t ... read more

If you notice that your headlights are flickering at night, that's something to pay attention to. While there could be many different things that could cause that problem, one possibility is your vehicle's alternator. The alternator takes mechanical energy from the engine and turns it into electricity, in essence a generator. The current it makes charges the battery and supplies power to the vehicle's electrical systems. An alternator is made up of several different parts: a pulley, magnets, coil wires, brushes and a voltage regulator. While your vehicle is running, these parts get a good workout and, after time, they begin to wear out. Other symptoms of a failing alternator include your vehicle's lights dimming, the power windows going up and down more slowly than they used to, your power seats not moving quite as fast as before. Another sign of a worn out alternator is engine stalling. Vehicles with fuel injection require a certain amount of power, and w ... read more

If every road was straight and smooth, we wouldn't have to worry much about wheel alignment. But they're not, so we do. Hitting potholes or driving on rough pavement can knock your vehicle out of alignment and you'll notice it in one of several ways. Your steering wheel may not be centered when you're driving straight ahead, or your vehicle may pull to one side. You may find your tires wearing on one side or they may squeal. All are signs that could point to you needing an alignment. Your wheels should be perpendicular to the road and parallel with each other. If not, your tires will wear out faster and your vehicle won't go straight on a level straightaway. In alignment, there are several factors that must be checked. One is camber. Your wheels should be straight up and down if you look at them from the front. If not, you'll wear your tires unevenly on one side. Another factor is caster, the angle of the steering pivot. Most vehicles have what ... read more

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away. Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs. While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket. Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight. But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak. You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on. All those are signs of leakage and time to bring your vehicle in for our technicians to check out. In some vehicles, taking ... read more
