As you know, today’s vehicles rely on a lot of computers in them to keep them running clean and efficiently. Those computers depend on information delivered by several sensors throughout the engine and exhaust system. And one of the most important is the oxygen sensor. Known as the O2 sensor for short, it looks for too much unburned oxygen that has made it into the exhaust. That signals something isn’t right with the engine’s air-fuel mixture. The sensor sends signals to the engine’s computers, which can then make adjustments to make sure the engine is running as it was designed to. Some vehicles can have several O2 sensors, and since they can measure oxygen at various points in the combustion/exhaust process, the computers can pinpoint where the problems lie. For example, an O2 sensor can detect how much oxygen is coming out of the engine’s combustion chamber, and another one can measure oxygen coming out of the catalytic co ... read more

What's the dif? To an automotive technician, it's the differential, a part of your vehicle that helps direct power from the engine to the wheels. The differential is a gearbox that enables the drive wheels to turn at different speeds (they do that when you turn). Inside the differential is a fluid that makes sure those gears and other parts are lubricated since there are a lot of metal moving parts in there. (Your vehicle may have more than one differential in it depending on the drivetrain.) As you can imagine, it's important that the lubricant in those differentials do its job. Otherwise, the gears may be damaged by heat and friction. The more you drive your vehicle, the more likely it is for that lubricating fluid to break down. So, it's important to have the differential fluid exchanged every so often. Your vehicle's manufacturer recommends how often your model should have that done, but a common interval is every 30,000-60,000 miles/50,000 km ... read more

Maybe your vehicle feels like Breaking Bad. In other words, when you brake, things are bad. You may find it takes you a longer distance to stop, you feel a vibration, or it’s pulsating when you depress the brake pedal, or perhaps your vehicle pulls to one side. Those can be symptoms of failing brake drums. While a lot more vehicles these days have disc brakes, many vehicles still have brake drums, almost always in the rear wheels. The drum is a cast iron shallow cylinder that surrounds the other parts, including curved brake shoes that press pads against the drum to slow you down or stop the vehicle. Any time you have things going wrong with your brakes, you should get them fixed soon. Safely operating any vehicle depends on having the brakes be able to slow and stop you dependably. It can make the difference between avoiding a collision and having one. When you bring your vehicle in, a technician will inspect your braking system. Depending on ... read more

There's something you can do that helps your tires last longer, wear more evenly and your vehicle handle better. "Sign me up," you say! Wondering what that is? It's aligning your wheels, and it will literally point you in the right direction when it comes to a better and safer driving experience. When your vehicle was designed, the engineers made sure your tires were all pointing the same way by designing the suspension to make optimal contact with the road. That way the ride is smooth, you don't feel vibrations or shimmying and your vehicle travels in a straight line, without pulling to one side or the other. Unfortunately, your vehicle is not brand new; time and distance take their toll. After hitting countless bumps, potholes, or the occasional curb, your suspension gets knocked a little out of kilter. Those precise angles the engineers planned on for your vehicle? They get out of whack Uneven or premature tire wear is one of the first signs your alignment may be o ... read more

Engine air filters may not seem like a big deal, but when they’re clogged up with dirt, dust, and insects, your engine could wind up choking for air and not delivering you the power and performance it was designed to give. There are actually a couple of air filters in your vehicle. One filters the air going into the cabin (the cabin air filter), and the other filters air going into the engine. That engine filter is the one we’re talking about. After several months and long distances traveled, your engine air filter accumulates the junk it’s preventing from getting into your engine. You may notice your engine misfiring, your acceleration may not be what it used to be, it may make strange noises, and the Check Engine light may come on. When you notice any of those signs, it’s time to bring in your vehicle to have us figure out what’s going on. We’ll visually inspect your air filter. Keep in mind that your vehicle’s manufacturer ... read more

You may have heard about an important part of your vehicle's engine called a timing belt, and many know that if that belt breaks, it can cause some very serious engine problems. Not all vehicles have them, and the ones that do generally have smaller engines. The timing belt keeps the engine synchronized so that every time a spark plug fires, the crankshaft, camshaft, pistons, and valves are all working together. Timing belts will eventually have to be replaced, and most vehicle manufacturers recommend when that should be. Typically, it's around every 60,000-100,000 miles, or 100,000-160,000 km. It's a good idea to stick to your vehicle's schedule or be alert for signs that the timing belt may be failing prematurely. Some of those symptoms? Maybe your engine won't even turn over when you try firing it up. You might hear a ticking or banging sound under the hood. Perhaps you spot an oil leak or notice the engine misfiring. If any of those are happenin ... read more

No, ERG isn’t the sound a pirate makes. It’s a part in your vehicle that recirculates exhaust gas to reduce certain gases and pollutants in the atmosphere. In fact, ERG stands for “Exhaust Gas Recirculation.” One gas our vehicles may make when they burn fuel is nitric oxide, which can play a big role in creating smog and acid rain. It’s better for our planet if our vehicles aren’t spewing that into the air. One inventive way of reducing it is by taking the exhaust and channeling it back to the vehicle’s air intake system. When it travels through the engine again, its composition is changed, and it comes out cleaner. It also helps the engine be more efficient. The EGR valve can fail after a while, and some signs you may notice are the engine is miss firing, it may suddenly lose power or your Check Engine light may come on. You may also see your fuel economy decrease or hear your engine knock. A bad EGR valve ... read more

When you are pointing your vehicle straight down the street, it should go straight. That’s pretty straightforward, right? Sometimes, though, you may notice you have to keep adjusting the steering wheel to keep going straight. While that could be caused by many different issues, one possibility is that you have a failing or bent control arm. Another sign is that when you brake, your vehicle pulls to one side or the other. Sometimes your suspension may sound noisy, especially when you’re traveling on rough surfaces. A damaged control arm may also make it almost impossible for you to get a good wheel alignment. The control arms are part of your suspension, and some vehicles have upper control arms and lower control arms. Not all have the same number of control arms, but one thing is important: If you have worn bushings on your control arms or a worn-out ball joint, the control arm on the other side should also be replaced. The rubber b ... read more

A driver called in to the shop the other day saying his European sports sedan had an odd problem. He was driving when his car started to slow down. Applying more throttle didn't help. He pulled over to the side of the road, shut the engine off and waited a few minutes before starting it up again. It ran fine… for a couple of minutes. Then the same thing happened. He was able to finally get home by stopping and restarting, and he was calling to see if we could take a look at it. Turned out it was one of his car's fuel filters that choked up with debris so badly that enough fuel couldn't get through it. When he stopped the car, enough fuel could flow through the unpressurized fuel line to supply enough fuel for a couple of minutes when he restarted his car. But then the pressure would cause things to clog again. There are other symptoms that point to a failing fuel filter. Perhaps your engine misfires, your vehicle is hard to ... read more

It's safe to say that most drivers take their brakes for granted. You press on the brake pedal and the vehicle slows down or stops. It's easy to see why it is so important for your vehicle's brakes to be working correctly. Brakes are an important safety feature of any vehicle. When it comes to your brakes working correctly, maintaining them regularly will ensure that you will always be able to slow or stop your vehicle in any situation, whether on a sunny day on dry pavement or a bad weather day on slippery surfaces. And that is why regular brake service is such a sound investment for all drivers. The combo of brakes" and "surprises" doesn't usually end well. You might already know about some of the parts of your braking system. Terms familiar to you might be pads, rotors, and calipers. In short, the calipers press the pads, which in turn contact the rotors. The resulting friction slows your vehicle. Another type of brake uses a drum and brake ... read more
