The drive belt tensioner is a pulley that is mounted on a spring mechanism or a pivot mount that you can adjust. It makes sure that the drive belt has enough tension.
Belt tensioner conceptThere is an entire system that is responsible for transforming engine-generated power for numerous components like the alternator, water pump, and air conditioning compressor. This system functions thanks to the drive belt which connects the alternator, water pump, and other components. A specific amount of tension is necessary for these parts to receive any power. Also, the belt tensioner has four crucial components: a pulley, tensioner arm, spring, and base. The base maintains these components in their place.
Common issues with a faulty belt tensionerA faulty belt tensioner can cause the vehicle to have grinding noises, cracks, and worn-out drive belt edges.
