(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and check to correct gasket
installation and for foreign material on the pulley teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
Check the turning smoothness of the idler pulley.
If necessary, replace the idler pulley.
3. INSPECT TIMING BELT TENSIONER
(a) Visually check tensioner for oil leakage.
HINT: If there is only the faintest trace of oil on the seal on the
push rod side, the tensioner is all right.
If leakage is found, replace the tensioner.
(b) Hold the tensioner with both hands and push the push
rod strongly against the floor or wall to check that it
doesn’t move.
If the push rod moves, replace the tensioner.
(c) Measure the protrusion of the push rod from the housing
end.
Protrusion: 10.5–11.5 mm (0.413–0.453 in.)
If the protrusion is not as specified, replace the tensioner.
