If you've ever heard a squealing sound under your vehicle hood, chances are it was your serpentine belt. More importantly, the belt powers the alternator. The alternator creates electricity that's used by your vehicle's electrical systems and also charges the battery. Without the alternator, the battery will go dead after a short distance.The serpentine belt may also run the pumps for both the power steering (some are electric) and power brakes (some use vacuum boost).And, on most vehicles, the serpentine belt powers the water pump. The water pump circulates coolant through the engine to keep it within optimal operating temperatures. On some Rockville vehicles, the water pump is powered by the timing belt instead of the serpentine belt.When they understand what it does, Rockville drivers realize that if it breaks, it affects a lot of systems. That's why vehicle manufacturers outline recommended replacement guidelines in the owner’s manuals. If thi ... read more

You know you need newtires, but you're not sure what type. You look at a tire to get the size: 225, 50, R, 16, 92, H. All the way to the Rockville service center you keep repeating it over and over. You even say it over in your mind while waiting in line. Then you get to the counter and the manager asks what size you need. Then your mind goes blank.Tire size can be confusing for many Rockville drivers. There's so much on the side of the tire, and it's hard to keep straight.Even though there's a lot on a tire - if you know what it all means, it's actually more helpful than confusing for Rockville tire shoppers. Let's start with the size number.For example, let's say a tire reads: 225 50 R 16 92 H. The 225 part is the width of the tire in millimeters - the width between the sidewalls of an inflated tire with no load. The 50 is the aspect ratio - the ratio of the sidewall height to the tread width. Off-road tires will have a higher number and high p ... read more

Let's talk about transmission service. It can be easy for Rockville drivers to forget about getting their transmission serviced because it doesn't need it very often. It's easier for people in MD to remember to change the engine oil - you know, every 3,000 miles or 5,000 kilometers. But proper transmission servicing keeps your vehicle running smoothly and helps you avoid repairs down the road.The transmission undergoes a lot of stress. The grit you can see in used transmission fluid is actually bits of metal that wear off the gears in the transmission. In addition to that, the transmission operates at very high temperatures. Usually, it's much higher than engine temperatures. Those high temperatures eventually cause the transmission fluid to start to break down and lose efficiency.As the fluid gets older, it gets gritty and doesn't lubricate and cool the vehicle transmission as well - leading to even more wear. The fluid can actually get sludgy and plug up the maze of fluid p ... read more

Your engine is like a finely choreographed dance. All the parts have to work together. If the timing is off at the ballet, dancers crash into each other and fall down. It the timing is off in your engine, it may not run at all. One of the most intricate dances in your engine has to do with the combustion cycle.Your vehicle engine has cylinders in which a piston travels up and down. At the top of the cylinders are valves that open to bring in the air and fuel. And there are valves that open to let out the exhaust after the fuel has been burned. Call Auto Clinic Care at 301.881.7891 for answers about your timing belt, or drop by our Rockville, MD, service center on 5531 Nicholson Lane. It's critical that the values be timed to open and close at precisely the right time in the combustion cycle, or the engine will run poorly or not at all.The timing belt is responsible for rotating the shafts ... read more

All new passenger vehicles on our Rockville, MD, roads now have tire pressure monitoring systems – TPMS for short. They are designed to alert you if your tires are underinflated. Since they are fairly new, a lot of people have questions about them.First off, the most important thing is that you still need to check your tire pressure every week – or at least every time you gas up. The TPMS system alert comes in when your tire is 20 percent below the factory recommendation. So if the recommended pressure is 34 pounds per square inch, the TPMS warning won't come on until the pressure is at 28 pounds. That's significantly underinflated, enough to raise safety concerns.The worst is tire failure. A severely underinflated tire can overheat and fail. Also, handling degrades to the point that you may not be able to steer out of trouble. Also underinflated tires wear out faster and they waste fuel. So ... read more
