Chirp From the Timing Belt Area
(Supersedes 08-045, dated May 21, 2010, to revise the information marked by the black bars/shown with asterisks)
REVISION SUMMARY
SYMPTOM
There is a chirp coming from the lower timing belt area. The noise is most often noticed at idle, usually after the engine has warmed up.
PROBABLE CAUSE
The idler pulley mounting surface is tilted, causing the edge of the timing belt to rub against the side of the pulser flange on the drive pulley (gear).
VEHICLES AFFECTED
CORRECTIVE ACTION
Install a taper shim kit, and grind a deeper relief on the engine mount bracket if needed.
