Drive Belt: Description and Operation

The 4.6L (2V) OHC engines are equipped with a multi-vee Front End Accessory Drive (FEAD) belt to ensure maximum life. When replacing drive belt, it should be of the same type as originally installed.
- Engines equipped with an automatic drive belt tensioner will not require any drive belt tension adjustment for the life of the drive belt.
- Loose drive belts will result in slippage which may cause a noise complaint or improper accessory operation.
- Loose drive belts may result in operational problems like generators not delivering proper charge or other concerns.

NOTE:
- Drive belts with automatic drive belt tensioners do not require adjustment.
- When an accessory drive belt is replaced or reinstalled after a service procedure, the drive belt does not fully seat into pulley grooves until engine has run for several minutes.





This vehicle is equipped with:
- a V-ribbed serpentine accessory drive belt.
- an automatic drive belt tensioner.

Replacement drive belts should be of the same type as originally installed.

The drive belt condition should be checked:
- at 160,000 km (100,000 miles),
- then every 24,140 km (15,000 miles).
