2.3L ENGINE BELT SQUEAL – VERIFY PROPER SERPENTINE BELT AND TENSIONER

FORD:	2006 Fusion
MERCURY:	2006 Milan

2006 Fusion and Milan vehicles equipped with a 2.3L engine and built on or before 11/1/2005 may exhibit belt squeal or other front end accessory drive (FEAD) related concerns.

Vehicles may require replacement of both the FEAD drive belt and drive belt tensioner if service of either of these components becomes necessary.

SERVICE PROCEDURE

Determine the build level of the FEAD components. For engines equipped with a tensioner shield requiring the replacement of the drive belt or tensioner, both parts must be updated to the latest level.
If the vehicle is not equipped with a tensioner shield, do not continue with this. The new level components may be serviced individually as required. Repair according to online Workshop Manual. The correct service part numbers are listed below.
If the vehicle is equipped with a tensioner shield, remove and discard the following:
1. Shield
2. Tensioner
3. Drive belt
Install the latest level components as listed below:
1. Automatic Transmission Equipped Vehicles:
  1. Tensioner: 6E5Z-6A228-BA
  2. Drive Belt: 6E5Z-8620-B (Green Stripe)
2. Manual Transmission Equipped Vehicles:
  1. Tensioner: 6E5Z-6A228-BA
  2. Drive Belt: 6E5Z-8620-C (Blue Stripe)
For all repairs, verify that the drive belt tensioner range indicator is within the “V” band. (Figure 1)

If the tensioner is out of range, or belt squeal persists, follow normal diagnostic procedures.
