Rockville Auto Repair

Most Rockville drivers are too young to remember life before power steering - cranking those great big steering wheels! It was a pretty good workout. Now power steering is standard. Let's look at how it works. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine; a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.These hoses can develop leaks, so it is a good idea for Rockville drivers to have them inspected at every oil change. Low fluid can damage the power steering pump. That is why power steering fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owner's manual for the right type - or just ask your friendly and knowledgeable ... read more

Winter is one of the hardest times to keep your vehicle clean. But did you know neglecting to wash your vehicle in winter could cost you a significant amount of money in the long run? Here's why. Many areas deal with snow and ice in the winter, and the salt and sand that are used to keep the road surfaces from being slick are also super corrosive to a vehicle's metal body and undercarriage.  That includes all the parts underneath that can be splashed with brine, saltwater and other road debris.  Winter is also tough on vehicles where there isn’t snow, sometimes from ocean salt or winter's extra humidity and rain.  If you have any breaks in your vehicle's paint, whether it be from a little fender bender or a stone chip, that corrosive winter moisture can get through those cracks and start eating away at the metal underneath.  If you can, you should get any dents or damage fixed as soon as possible so your vehicle has a protective layer of paint between road che ... read more

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now? Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You ... read more

When you head to the doctor, you probably have it in your mind what you're going to say about why you don't feel good.  That way your doctor can use that information to diagnose your problem. You might want to think of that same approach when you take your vehicle in for a repair. Experts say what will help the service advisor most is for you to bring in some well-organized descriptions about your vehicle's issues.  You might even want to write them down so you don't forget.  Is there an unusual smell?  What does it smell like?  Does the problem happen first thing after starting out? If there's an odd sound you hear, is it dependent on speed?  Does it change when you turn a corner?   Keep your expectations realistic.  Some conditions may take a long time to diagnose and repair.  If you go thinking you'll be in and out in no time, you might be disappointed when you're told there are other customers ahead of you and you may have to come b ... 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

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
