You've likely heard how important oil is to your vehicle's engine. Did you know that there's one part that's responsible for holding that oil so you can use it every day? It's called the oil pan, and it sits at the bottom of the engine. The oil pan is a vital, though simple, part of your engine's lubrication system. Oil circulates through parts of your engine to keep them lubricated. It reduces friction so everything works smoothly. Without oil, friction would quickly destroy your engine. The oil pan keeps that oil contained in the lubrication system, so it's important that the oil doesn't leak out. Since it's a metal part attached to another metal part, there is a gasket between the oil pan and the part of the engine it attaches to. Various things can put stress on the oil pan and gasket, including weather extremes, the speed you're traveling and the condition of the oil. You may drive over a couple of bad roads and kick up debris onto your oil pan. All this wear and tear, heat and ti ... 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

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

If your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you. No, really, it is. So listen to what it's saying and you could avoid a much more costly repair down the road. A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on. One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels. Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. Think of it. Hydraulic power steering has many components that need to work in tandem. The power steering fluid may be too old and contaminated. Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening. Other causes of grinding while turning can be problems with the suspension in the front. Yo ... read more

Colder weather brings out the worst in a vehicle's battery. On a very cold day, you may have experienced that your engine cranks slowly when starting. But while it may be the battery itself, it may also be the parts that transfer the power to other the other electrical components, the battery cables. After all, you have to have some way to get the current out of the battery and out to where it needs to go. Battery cables have a couple of enemies: corrosion and age. You may have looked under the hood and noticed a light-colored powder or crust around the terminals. That's what happens when acids corrode the ends of the battery terminals. Corrosion inhibits the connection and may reduce the amount of power getting to the electrical accessories to the point where they are not working correctly, if at all. Here are some symptoms of problems with your battery cables. You might notice a clicking sound when you turn the key, some of your vehicle's electrica ... read more

If your vehicle creaks and squeaks when you drive down the road, it may mean that some of the metal parts are rubbing against each other and need to be lubricated. Those could be parts of the suspension, steering system and the drivetrain. Years ago, most vehicles had to have their chassis (what you think of as the frame) regularly lubricated. Newer vehicles are made with what some call "lifetime lubrication," but there are still parts of the chassis that need to be maintained with lubricants. Your service advisor can help you know when that needs to be done. In your owner's manual, the vehicle's manufacturer lists components that need regular maintenance. Things like u-joints, steering joints, sway bars, bushings and joints in the suspension. Some of them may have that "lifetime lubrication," while others may not. When you bring your vehicle in for service, a technician will look for any parts that have grease fittings. They will inspect these components ... read more

There's a segment of the TRUCKEE area population that's not committed to proper vehicle maintenance. Now, the ignition system in your vehicle is electronic and controlled by the engine management computer. Spark plugs rarely get fouled and will last for as much as 100,000 miles (160,000 kilometers). So tune-ups used to force you in to The Auto & Tire Doctor Inc for service, and while you were there you just took care of whatever else was on the list.
Also, in recent years, a large percentage of new vehicles in TRUCKEE have been leased. These folks plan on turning the vehicle in after two or three years, so they haven't focused on the maintenance that helps a vehicle last longer.
Given all that, what's the benefit to keeping up with factory scheduled maintenance? Well, your vehicle will perform better and return better fuel economy.
Those benefits pay for themselves as they go along. The big plus is that&n ... read more

You know you have an accelerator pedal; step on it and your vehicle is supposed to go. But did you know there is a part in your vehicle that keeps track of where the throttle is? It's called the Throttle Position Sensor, or TPS. The TPS is a sensor that helps your vehicle figure out the right mix of air and fuel is reaching your engine. It does that by keeping track of the throttle and sending that information to your vehicle's computer. Other factors play a role in how well your engine is performing, including air temperature, how fast the engine is turning over and air flow. When the TPS isn't working right, you may find your vehicle won't accelerate or doesn't have the power you're expecting when you press on the accelerator. In some cases, it may accelerate on its own. Sometimes your vehicle won't go over a certain speed. Your Check Engine light may go on. Any of these symptoms should be checked out soon. If your TPS stops working rig ... read more

When it comes to oil changes, things are really changing. Most newer vehicles require synthetic oil, and while it costs more than conventional oil, it doesn't need to be changed as often. When conventional oil was the only game in town, you changed your oil every 3,000 miles/5,000 km. But as technology in newer vehicles has rapidly changed, so has oil technology. Synthetics have been around since the seventies. Even though they start with a conventional oil base, they are engineered in a chemical processing plant with properties that allow them to keep your engine lubricated at very high temperatures. They are more uniform and consistent. Synthetic oil doesn't break down as easily, so it lasts longer than conventional oil. And synthetic oil can flow more easily, even in extremely low temperatures. As you can see, it has performance advantages at both temperature extremes. Generally, in recent years automakers have been shipping most of their vehicles ... read more
