Rockville Auto Repair

Hello Rockville drivers, let's talk about batteries. Car batteries are just like any rechargeable battery. They will eventually wear out and die. If you are shopping for a new battery in Rockville, here's some auto advice to help you.There are two measurements to consider when purchasing a new battery: cold cranking amps and reserve capacity. The power required to start a cold engine is measured in cold cranking amps. The number you need is determined by what kind of vehicle you drive and where you live. In general, higher-cylinder engines require more cold cranking amps than lower-cylinder engines. In other words, an eight-cylinder engine needs more cold cranking amps than a six-cylinder one. Also, diesel engines require more cold cranking amps than gasoline engines.The weather where you live in MD also determines the number of cold cranking amps you need. The colder the vehicl ... read more

There are a lot of drivers in Rockville who are due for a differential service, but had never heard of a differential before.With front-wheel drive being so common in MD these days, the differential is just taken care of during a transmission service, so most Rockville folks don't even have to think about it. And rear-wheel drive differentials don't need to be serviced for years, so it's understandable that it's not something on the top of your mind. It's not uncommon for people in Rockville to not know they have a differential, let alone know that it needs service.To better understand what a differential does, think about a track at any MD high school. There are lanes marked off on the track. For the longer distance races, the starting lines are staggered. The starting lines for the outside lanes are ahead of the starting lines for the inside lanes. That's to compensate for the longer length of the outside lanes. Staggering the starting lines means that each runner h ... read more

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern vehicles are so reliable, they are virtually maintenance free."Any good myth has some elements of truth. No offense to Rockville Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.Here are some examples for our friends in Rockville. Some vehicles in Rockville no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints. -Chalk one up for the myth.On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts are up in ... read more

The drive train in your vehicle includes all the components that transfer power from the transmission to the wheels. Those components differ depending on what type of vehicle you drive, namely, front-wheel drive, rear-wheel drive, all-wheel drive or four-wheel drive. The preventive maintenance your driveshaft needs will also differ by what type of vehicle you drive.Let's start with front-wheel drive. In this vehicle, the transmission and the differential are combined in one component, known as the transaxle. The transaxle is connected to two half-shafts (axles), which are then connected to the wheels with a constant velocity (or CV) joint, which is protected by an airtight rubber boot.Auto Clinic Care service for this type of driveline includes servicing the transaxle and inspecting the CV boot. If the boot is damaged, the CV joint will need to be inspected, and the boot will need to be replaced. If you hear a clicking noise i ... read more
