As 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 mu ... read more

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs. While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak. You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out. In some vehicles, taking ... read more

The heat is on, and your vehicle takes a beating when it is.  Several of your vehicle's systems are under extra stress in hot weather, so here are a few to make sure are getting the care and maintenance they need. It makes sense that the cooling system is one to make sure is in top shape.  Vehicle breakdowns in summer are often due to a problem with one of the cooling system's components.  Coolant levels have to be up to specs, the ratio of coolant to water must be correct and the hoses, pumps, belts and radiator must all be working properly in order to prevent vehicle overheating. Summer is also hard on your air conditioning system.  You might find that no air is blowing out of the vents or maybe only hot air is coming out.  Air conditioning equipment is best diagnosed and repaired by a trained and experienced technician.  The problem could be in any number of components, including the condenser, compressor or blower motor. You may think the battery gets ... read more

Think of how many times you put your foot on your vehicle’s brake pedal every day.  And think of how much you rely on your brakes to slow down and stop your momentum.  When it comes to safety systems, your brakes are at the top of the list, and that’s why it’s so important to keep them in top condition. Brakes are something you make sure you keep maintained before they start showing signs of problems. Some of those signs are a grinding sound when you step on the brake pedal, your vehicle pulling to one side when you brake, you don’t feel your brakes stopping you as quickly as they used to, or you notice the brake light is illuminated on your instrument panel.  We ask a lot of our brakes.  They have to work no matter how hot or cold it is outside.  That means whether it’s sunny, snowing, raining, or icy; you’re traveling at highway speeds or school-zone speeds; or when suddenly you find yourself trying to avoid hitting another ... read more

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU. Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case. As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities. If you don't have your transfer ... read more

Your vehicle is like you in a way.  When it gets hot, it needs to be cooled down.  And one of the key parts to keeping it cool is the water pump. Now, that's a bit of a misnomer.  It IS a pump, but it's pumping coolant, not pure water.  Cooling off your engine is vital since it builds up heat when it creates power by burning fuel.  Your water pump acts as a way to recirculate that coolant.  It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat.  Cooled off, the coolant is recycled through the water pump to start the journey again. The water pump works by taking mechanical power from the engine, usually from a belt.  Obviously, that belt has to be in good condition and adjusted properly or else the water pump won't be able to do its job. Here are some things to look for that will signal problems with your water pump.  If your heat gauge is erratic or sho ... read more

A set of new tires isn't probably high on anyone's list of exciting purchases.  But since your life is literally riding on them, it's probably a good idea to know when it's time for you to buy new ones. If you've been feeling your vehicle slipping more in wet weather or it takes a longer distance to stop, those are a couple of signs you may need new rubber all around. Here's how to make your decision. First thing to do is look at your tires.  The surface of the tire that contacts the road is the tread. When that tire was new, the tread was deep (the grooves in the rubber that provide traction). If they're starting to look somewhat smooth, you have a seriously worn tire that definitely needs replacing.  Bring your vehicle in for us to look at your tires and we can check your tread with a tread gauge. Also look at the sides of your tires.  If they have cuts or cracks in them, or if you see signs of bulges or scrapes made by hitting curbs or potholes, those could be si ... 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

Seems like these days, we're hearing about more and more electric or hybrid vehicles.  Keep in mind that conventional gasoline internal combustion vehicles have important electrical components, too, and it's important to make sure they're operating at their peak. In a vehicle with a gasoline engine, the part that keeps the battery charged is the alternator.  It converts the mechanical energy created by the engine into electrical power.  To do that, a shaft in the alternator has a pulley on one end that's driven by a belt that is turned by the engine.  A series of magnets then spins around coiled wires and it creates alternating current, or electricity. Your vehicle uses that to charge the battery that, in turn, keeps other electrical components in your vehicle working. Here are a few signs that the alternator isn't doing its job right.  The battery keeps going dead, your instrument panel's battery light is on (it looks like a rectangle with a - and + inside and ... read more

Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law.  Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either. The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules. If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes ... read more
