Is this product for you?
You can rely on Gates to supply premium quality DriveAlign Automatic Belt Tensioners. Gates ensure every tensioner that is manufactured is built to rigid tolerances and specifications which guarantee that every tensioner looks, fits and functions just like the original equipment fit. The Gates tensioners are manufactured using the same technology as the original equipment manufacturer (OEM) part, which assures it is a factory match. The patented vibration damping system helps to improve the tensioners, belts and accessory life, and the torsional round spring design provides consistent tension which does not allow for contamination.
Tensioners, like any other part unfortunately don't last forever and will require replacing at some stage. Over time dirt and grime can get into tensioners, making the springs and dampers bind. Stop and go driving can also vary the engine load which can result in irregular tension. On average, a tensioner will cycle 200 million times in its service life which adds to the general wear and tear.
If this part is not replaced, it can cause the belt to break or fly off the drive, which in turn can result in a breakdown which may lead to further implications.
A wide array of problems can arise from an improperly tensioned serpentine belt:
Insufficient charging of battery
Loss of power steering
False check engine lights
A/C System to not perform optimally
