A Fan Clutch is just another automotive part of that cooling system in your BMW. It is designed to allow your engine to warm up quickly, reduce horsepower drain on the engine, reduces drag, and therefore improves engine efficiency. Your fan clutch plays a very important auto part in keeping your BMW cool. Failure of this component would result in an overheat condition that could damage your engine.

Hot weather driving will be here before we know it! Fan clutch operation is one of those items that needs to be working properly. No, it’s not there for looks. Unlike some of the plastic composite or rubbery items that are part of your cooling system, the fan clutch does not “crack” or “break” apart. But, over time it can cease to work effectively and perhaps not enough to keep your engine cool. In worse case, it may just stop all together. At that point, your engine could become overheated and severe damage may result.

You will want to have your cooling system checked out before a long trip or the next time you stop in for your oil service. There are some subtle signs of performance deterioration that your tech may detect, (before you drive off and overheat). Also, always pay attention to your temp gauge or any warning light that illuminates. Ask your trained Master Tech to perform a cooling system check. You never want to drive in an over heated condition! Do not ignore your warning indicators. If a warning light comes on, be sure it is safe to pull to the side of the road, and turn off the engine. Then call AAA or a towing service.

It is easy to make an appointment online with us. Don’t wait until the last minute or until summer vacation season to get your fine German Auto checked out.

Happy Motoring!
