Archive for December 2023What Is an EGR Valve? (EGR Valve Service)Posted December 17, 2023 7:22 AMIf 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:
Depending on its condition, the EGR valve can be cleaned or it may need to be replaced. Consult with your service advisor to see what options are recommended to you. The EGR system is part of your vehicle's pollution and emissions control equipment. If you care about keeping our planet's atmosphere clean, you'll want to make sure it's doing its job—for everyone's benefit. Lakeside Certified Auto Things Aren't Always What They SeemPosted December 10, 2023 7:27 AMIf you drive, you know at some point, something's going to go wrong with your vehicle. And sometimes, it's pretty easy to figure out what's wrong, like a flat tire. But sometimes your vehicle's symptoms can be really puzzling. One driver in OH was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual. He was trying to figure it out, but none of it made any sense. His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator. It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems. You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree. That caused a tiny crack in his rear stoplight. That crack had gone unnoticed until that July day. Turns out a summer rain allowed water to seep into the taillight casing, so this time when he drove to work, there was enough moisture inside it to cause his stop light to stick on. When the stop light is on, the car's computer is programmed to act as if the driver is pressing the brakes. It also disables the cruise, accelerator and cruise control when the brakes are on, producing all of the symptoms. Replacing the stop lamp switch fixed everything. So, while some things that go wrong with your vehicle are pretty obvious, many seemingly defy all logic. That's when a trained technician can scope things out, replace the right part and get you going again. Lakeside Certified Auto

The Right Oil for the Season (Engine Oil Viscosity)Posted December 3, 2023 10:32 AMAs the temperatures plunge, certain types of engine oil may not flow as easily as they did when it was warmer. Makes sense, doesn't it? Just like molasses gets thicker as the temperature goes down, engine oil does the same thing. So, maybe you're wondering if you have to change your oil as the seasons change so it's just the right thickness to lubricate your engine parts. How well engine oil flows is called its viscosity. There are different types of oil—some that have just one viscosity and others called "multigrade" oils. Here's the difference. A single viscosity oil will flow better when it's hot but not as well when it's cold. A multigrade oil is engineered so that its flow properties at cold temperatures are different than they are at warm temperatures. In other words, a multigrade oil can start out in colder temperatures acting like a thinner oil and then behave like a thicker oil when it's warm. That's a pretty cool trick and it's why multigrade engine oil is used in nearly all vehicles. Your vehicle's manufacturer has the correct viscosity of oil for your particular model included in the owner's manual. Another choice you have to make when it comes to engine oil is whether you use conventional oil, synthetic oil or a blend of the two. Synthetic oils have some advantages over conventional, such as resisting breakdown better and withstanding higher temperatures. Check with your service advisor to see which viscosity and type of oil is recommended for your vehicle. It's important that in cold weather, the oil flows through your engine at the right thickness so that parts are being properly lubricated. That will make sure you'll get good fuel economy and performance, no matter what the temperature is.
