Get the Best Priced BMW 745Li Timing Belt Tensioner

Your BMW 745Li's timing belt synchronizes the movement of the camshafts and the crankshaft within the engine. The timing belt must maintain tension if it's going to move consistently. The timing belt tensioner is a piece of equipment that maintains tension on the timing belt so it doesn't go slack. If the timing belt tensioner is cracked or torn, the timing belt will not work correctly. You can buy a replacement timing belt tensioner for your BMW 745Li at PartsGeek.com.

One of the characteristic signs of a tensioner that's going bad is a rattling noise coming from your engine when you start your BMW 745Li or when you try to accelerate. You may notice other abnormal sounds as well, such as a humming noise from your engine or a screeching noise when you try to shift gears. Your engine may also begin to leak oil.
