Next >About BMW Belt Tensioner
BMW mainly manufactures high-end vehicles, motorcycles, and parts. In 2020, BMW ranked No. 32 on the Fortune list of the world's most admired companies. It provides affordable and reliable parts like the belt tensioner for car buyers. The belt tensioner is a pulley that is mounted on a spring mechanism or a pivot mount that you can adjust. A faulty belt tensioner can cause the vehicle to have grinding noises, cracks, and worn-out drive belt edges.
Although BMW has lots of auto parts with impressive performance, the belt tensioner still needs repair and maintenance after a long time of usage. The removal process for a belt tensioner is as follows. First, remove accessories in the way if needed (water pump, alternator, radiator hoses). Next, remove the belt from the accessories. Then remove the mounting bolts for the belt tensioner. Finally, pull the tensioner away from its location and compare it to the new unit. A belt tensioner should be checked every 50,000-100,000 miles. There are lots of top-quality and durable BMW parts available on our website. Choose among a vast selection of BMW parts at varied prices. Customers can find a lot of BMW parts online.
