Belt tensioner

Automatic tensioners are calibrated to provide the correct amount of tension to the belt for a given accessory drive system. Unless a spring or damping band within the tensioner assembly breaks, or some other mechanical part of the tensioner fails, there is no need to check the belt for correct tension.

The accessory drive belt is made of a material that slightly stretches and contracts in order for it to self-tension during operation. Due to the fact that it maintains a constant tension, there is no need for a tensioner to be fitted. In order to remove and install the drive belt it is important that the correct procedure is used.
For additional information, refer to Accessory Drive Belt - Vehicles Without Accessory Drive Belt Tensioner in this section.
