Your gasoline engine goes through some exhausting work. Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve. Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes. Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine. Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air. That way the unburned fuel could go through the engine again and produce p ... read more

If someone tells you to put the brakes on something, you know it means stop. And stopping is one of the most important safety maneuvers you can do in any vehicle. That means your brakes have to work properly. Let's face it. You stop dozens of times every time you drive. And over time, that takes its toll on your brakes. Friction is what stops your vehicle. Most newer vehicles have disc brakes, and the parts that wear out the fastest are those that rub against each other every time you stop, the rotors and the pads. The rotors are discs that rotate with the wheels, and the pads are removable surfaces that make contact with the rotors to slow or stop your vehicle. Bits of both wear off each time you stop, and when enough of either (or both) lose too much material, your brakes become unable to safely slow or stop your vehicle. The pads usually are the parts that wear out first. Signs that your brakes might be getting worn are: Y ... read more

You may live in a region where roads become pockmarked with craters known better as potholes. They're caused by moisture seeping through a compromised road surface that can freeze, expand and literally punch holes in the road. And when your vehicle hits one of those holes that's big enough, the impact can flatten a tire, bend a wheel or tear apart a suspension component. To minimize pothole damage, leave enough room between you and the vehicle in front of you so you can see the road surface and any upcoming potholes. That way you'll have time to slow down and steer around them. Also, if you see what looks like a puddle of water, it may be hiding a pothole underneath, so treat it as if was a pothole. If you keep your tires inflated to the manufacturer's specifications, they're more likely to withstand hard impacts. And the slower you're going when you hit a pothole, the less likely you are to break something. But if you do find you've hit ... read more

Here's a part of your vehicle you probably don't think about much: lug nuts. They're what fasten your wheels onto your axles. Pretty important, right? In order to take the wheels off your vehicle to service the brakes, rotate the tires, etc., the lug nuts have to be in good shape so a wrench will grip them tightly. Because lug nuts are on your wheels, they are exposed to all the elements of the road (salt, water, grime) and really take a beating. Unfortunately, some manufacturers have made them out of two different metals. Underneath is the working part of the lug nut, made of steel. On top is the decorative (the "good looking") part, made out of chrome, stainless steel or aluminum. After a while, the steel part begins to corrode and expands. That changes the shape of the outer cap, sometimes rounding off the hexagonal edges and making it hard (if not impossible) to either loosen or tighten the lug nuts since the wrench won't fit any more.  ... read more

Nobody has to tell you that computers are a part of so many things in our lives. Smartphones, kitchen appliances, vacuum cleaners, televisions. You name it—it has a computer in it. And your vehicle is no exception. The earliest cars relied on the technology of their time, and there was no such thing as a computer. But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems. There are various sensors throughout modern vehicles that measure thousands of data points. When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car. It displays certain codes that help technicians track down the culprit. But it's not just the diagnostics that are computerized. Everything from your vehi ... read more

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated. If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident. All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS. One system uses small sensors in the tires that continually check the pressure in each tire. That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire. Another system works with your antilock brake system to measure the size of your vehicle’s tires. When one wheel is going faster than another, it will spin faster. A computer sees that and alerts ... read more

The brake rotor, or disc, is attached to your wheel. The brake pads rub on the rotor to slow your car when you are driving in TRUCKEE.Rotors can warp, crack or become misaligned. They can also be damaged by worn out brake pads that scratch grooves into the surface. These conditions result in less contact surface for the brake pads, leaving you with reduced braking power.Over time and miles, rotors can also wear down below safe specifications. It is important for TRUCKEE drivers to know that simply replacing brake pads on a wheel with a bad rotor will not solve the problem. Depending on their condition, rotors may be resurfaced or replaced.Brake noise or a pulsation in the brake pedal are signs of potential brake problems that should be addressed right away. If you have any brake concerns, please have your friendly and professional The Auto & Tire Doctor Inc tech perform a thorough inspection.Give us a call.The Auto & Tire Doctor Inc12000 PIONEER TRLTRUCKEE, CA 96161 ... read more

You know how exposing your skin to sunlight can cause sunburn and other unhealthy things. Sunlight can also create major problems for your headlights. After they've been exposed to ultraviolet light, acrylic headlights can yellow and fog due to oxidation. And when that happens, less light can pass through the plastic, reducing the effectiveness—and safety—of your headlights. It's not just the UV light that causes headlights to turn cloudy. Road grime and debris gets kicked up and can scratch the plastic, diffusing the light that should pass through them when they're clear. Plus, when your vehicle was new from the factory, the headlights had watertight seals all around to prevent moisture from getting into them and fogging them up with water vapor. Just like clouds can hide the sun, tiny water molecules can diffuse the light from your headlight bulbs. Sure, you could buy replacement parts and start fresh. But the good new ... read more

If you've ever felt your vehicle hesitate, go, then hesitate again, you might think there's something wrong with the transmission. After all, it's not moving smoothly down the road. But there are plenty of malfunctions that can cause those symptoms, one of them being something you may have never heard of: the EGR valve. EGR stands for Exhaust Gas Recirculation. It's a system that channels small amounts of exhaust back into the engine to cool down the cylinders and reduce polluting gases. Those include nitrogen oxides that can cause smog. The EGR valve regulates how much of the vehicle's exhaust gas is recirculated. After years and long distances traveled, that valve can get clogged or fail. Sometimes the EGR valve can stick open. When the EGR valve isn't working properly, your vehicle can start releasing those nitrogen oxides and pollute the air. The symptoms of a malfunctioning EGR valve include: Engine losing power Engine idling roughly Pinging and knoc ... read more

Every one of us has a little procrastinator inside us. Some put off getting our teeth cleaned. Others put off answering our emails. Yet others put off calling friends and family (sorry, Uncle Joe). And there are those of us who put off getting our vehicle's service done, whether it's a repair or regular maintenance. You may make the excuse that you don't have time, it can wait until tomorrow, you have other things to do. Well, there are some things you should NEVER put off when it comes to your vehicle because that procrastination could have dire consequences down the road. The biggest one is changing your oil. Yes, it's one of those things you may hear somebody nag you about, but changing your vehicle's oil regularly is probably the one thing that will do the most to keep things running smoothly… and well. It's the lubricant that keeps metal engine parts from wearing out. Oil doesn't last forever and it gets dirty, so you have to swap it out for fresh every so often. How often ... read more
