On 4.7L engines, the tensioner (3) is equipped with an indexing tang on back of tensioner and an indexing stop on tensioner housing. If a new belt is

less.

Worn bearings on an engine accessory (A/C compressor, power steering pump, water pump, idler pulley or generator)
^
A pulley on an engine accessory being loose
^
Misalignment of an engine accessory
^
Belt incorrectly routed.
