Belt Tensioner - Dynamics
The accessory drive belt tensioner can be checked dynamically as follows:
1. With the engine running, observe the accessory drive belt tensioner movement. The accessory drive tensioner should move (respond) when the
A/C clutch cycles (if equipped), or when the engine is accelerated rapidly. If the accessory drive belt tensioner movement is excessive without A/C
clutch cycling or engine acceleration, check belt rideout. Excessive belt rideout (uneven depth of grooves in the belt) can cause excessive
accessory drive belt tensioner movement. Check rideout condition by installing a new belt. If excessive accessory drive belt tensioner movement
still exists, install a new accessory drive belt tensioner.
