How to install an elastic belt in 9 easy steps

Some engines have special serpentine or accessory belt drive systems that are not equipped with a tensioning device. Elastic belts such as Gates Stretch Fit® belts, have been developed specifically for them. These belts are self-tensioning and do not require the presence of a tensioner.  

Specific installation instructions exist for each Gates Stretch Fit® belt. These instructions are printed on the inside of the sleeve or you can find them in our online catalogue. Simply type in your product reference or the correct vehicle make and model. The sleeve also contains a reference to the appropriate installation tool. 

What follows is a typical installation in 9 easy steps making use of a universal Gates Stretch Fit® tool. For some applications dedicated Stretch Fit® installation tools are available.
