OVERVIEW
A combined crankshaft pulley and torsional vibration damper drive the engine mounted accessory components via a 6
ribbed polyvee drive belt. The drive belt is routed around the accessory component pulleys, and is maintained in full
contact by an automatic tensioner and idler pulley.
AUTOMATIC TENSIONER
The automatic tensioner comprises a deflection pulley mounted to a spring loaded pivot arm. The tensioner is located on
the longest side of the drive belt between the crankshaft and power steering pump pulleys. The automatic tensioner
pre-loads the drive belt in order to drive the accessory components, without belt slip occurring.
The automatic tensioner also provides the means to remove and install the drive belt.
IDLER PULLEY
The idler pulley is located below the generator pulley, adjacent to the automatic tensioner. The idler pulley deflects the
drive belt direction to increase the wrap angle around the generator and power steering pump pulleys.

Check FEAD belt for contamination. If contaminated, install a new
belt.
REFER to:

Check FEAD belt for correct application
FEAD belt does not
hold tension
FEAD belt cracking or
damaged
Tensioner worn or
damaged
Inspect FEAD belt for cracking or damage. Install a new belt as
required.
REFER to:
Accessory Drive Belt
(303-05B Accessory Drive - TD4 2.2L
Diesel, Removal and Installation).
Check FEAD belt tensioner for damage and correct operation. Install
a new FEAD belt tensioner as required.

Component Tests
FEAD belt tensioner
Static
The only checks required for the FEAD belt tensioner are for stick, grab or bind.
1. Remove the drive belt in the area of the tensioner.
1.
2. Using the correct tool, rotate the tensioner from its relaxed position through its full stroke and back to the
relaxed position to make sure there is no stick, grab or bind, and to make sure that there is tension on the
tensioner spring.
2.
3. If the tensioner meets the above criteria, proceed to the dynamic test. If the tensioner does not meet the above
criteria install a new tensioner.
REFER to:
Accessory Drive Belt Tensioner
(303-05B Accessory Drive - TD4 2.2L Diesel, Removal and Installation).
3.
Dynamic
The FEAD belt tensioner can be checked dynamically as follows:
With the engine running, observe drive belt tensioner movement, the FEAD belt tensioner should move (respond) when the
air conditioning clutch cycles (if equipped), the FEAD belt tensioner should move (respond) when the engine speed is
increased rapidly. If the drive belt tensioner movement is erratic without air conditioning clutch cycling or engine
acceleration, a pulley or shaft may be bent, or distorted. Excessive drive belt rideout (uneven depth of grooves in the drive
belt) can also cause excessive drive belt tensioner movement. Check condition by installing a known good belt.
