A “moan/whine” noise may be coming from the front of the engine at an idle. This may be caused by the tensioner pulley belt surface being rough.
Replace the tensioner pulley with a new pulley which has an improved surface finish which should reduce the possibility of noise. Refer to the following Service Procedure for details.
- Verify the concern while the engine is idling. The noise will be most noticeable at idle. The noise can be significantly reduced by either increasing engine speed or by adjusting belt tension. Belt tension can be adjusted by rotating the tensioner with a ratchet in a clockwise direction.
- If the noise has been confirmed as coming from the tensioner, replace the tensioner with a revised Tensioner (F4TZ-6B209-AA). Refer to the 1996 F-150 Powertrain/Drivetrain Service Manual, Section 03-05 for removal and installation procedures.
- Verify the repair.
