Drive Belt Tensioner: Description and Operation
Automatic Belt Tensioner-3.9L/5.2L/5.9L Engine
Correct accessory drive belt tension is required to be sure of optimum performance of belt driven engine accessories. If specified tension is not
maintained, belt slippage may cause; engine overheating, lack of power steering assist, loss of air conditioning capacity, reduced generator output rate
and greatly reduced belt life.
Drive belts on both 3.9L and 5.2L/5.9L engines are equipped with a spring loaded automatic belt tensioner. This belt tensioner will be used with all
belt configurations. Such as with or without power steering or air conditioning. Due to use of this belt tensioner, do not attempt to use a belt tension
gauge on 3.9L/5.2L/5.9L engines.
