REPAIR PROCEDURES/INFORMATION
Identify if noise is coming from the timing belt tensioner or tensioner bracket when the engine is cold.
(1)
With the hood raised, listen carefully where the noise is coming from. If the noise can be heard from around the timing belt cover area, there is a
possibility that the noise is coming from the timing belt tensioner.
(2)
Confirm if the noise is coming from the upper portion of the timing belt tensioner by using a stethoscope. If noise can be heard it's either coming
from the tensioner or bracket. Inspect the belt tensioner; if the cylinder body of the timing belt tensioner has a notch from wear (see Figure 2) the
tensioner will need to be replaced.
(3)
If the engine number is 572570 for SOHC or 572928 for DOHC and after, replace the timing belt tensioner bracket.
(4)
If the engine number is 572570 for SOHC or 572928 for DOHC and before, check to see if the cylinder body of the timing belt tensioner has a
wear notch. If so, replace the timing belt tensioner. If the cylinder body of the timing belt tensioner does not have a wear notch, replace the timing
belt tensioner bracket.
