Archive for December 2020A Non-Starter (Alternator Problems in Cold Weather)Posted December 27, 2020 7:41 AMAs the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad. But there's one more component to keep an especially sharp eye on during winter: your alternator. The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity. That includes the battery, which needs charging to keep its power topped off. The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity. It is connected to the engine by belts and pulleys. In cold weather, the material the belt is made from is less flexible than it is in warm weather. That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move like they do when the weather's warmer. With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it's cold. You may have a warning light on your instrument panel that looks like a battery. If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it's complicated. Pinpointing the cause involves testing the battery and charging system with diagnostic equipment. If it does turn out to be an alternator, there are options besides replacing it with a brand new, original equipment part. Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather. Take care of your charging system and it will take care of you. Lakeside Certified Auto Don't Be Shocked (Shock Absorbers)Posted December 20, 2020 8:56 AMIf you've ever ridden down a rough road on your bicycle, you know how hard a ride it can be. Yet drive down the same road in your car, truck or SUV and it miraculously will smooth out the ride. That's because it is equipped with shock absorbers. They are built to dampen impacts from road irregularities. But after taking hundreds of hits from potholes, railroad tracks and curbs, your shock absorbers can wear out. Besides the rough ride that can cause, there are other ways your vehicle's performance can be affected. When it comes to braking for example, you may take a longer distance to stop. That's because shocks help keep your tires in contact with the surface of the road. If the shocks aren't working properly, the tires won't make contact like they should. So when you slam on the brakes, your vehicle will take longer to stop. Consider what worn out shocks are doing to your tires. Since the bumps aren't being dampened as much, your tires can bounce up and down more. That can produce a problem of uneven wear called cupping. And when you start out from a stop, your vehicle may not have the traction it should since the shocks aren't keeping them down on the road as you accelerate. If you have front wheel drive, you may lose some steering control on acceleration. Obviously, many of these things involve safety concerns. Pay attention to any deterioration in your vehicle's ride quality. If your vehicle is starting to bounce up and down and its ride feels bumpier than before, head on over to your vehicle service facility and get your suspension checked out. Do the same if steering response isn't as good as it used to be. Notice that your vehicle nose dives when you brake? Are your tires wearing in an unusual manner? All are signs that your shocks may be on their last legs. If the last time you replaced your shocks was 50,000 miles/80,000 kilometers ago, a technician should evaluate them. Don't be "shocked" if it's time for new ones.
