INSPECTION
1. INSPECT TIMING BELT
NOTICE:

Do not bend, twist or turn the timing belt inside out.

Do not allow the timing belt to contact with oil, water
or steam.

Do not utilize timing belt tension when installing or re-
moving the mount bolt of the camshaft timing pulley.
If there any defects as shown in the illustrations, check these
points:
(a) Premature parting

Check for proper installation.

Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check if either
camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check if there are nicks on the side of the idler pulley lock
and the water pump.
(d) Even if there is wear or damage on only one side of the
belt, check the belt guide and the alignment of each
pulley.
(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and for foreign materials on the pulley
teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
(a) Visually check the seal portion of the idler pulley for oil
leakage.
If leakage is found, replace the idler pulley.
(b) Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.
3. INSPECT TIMING BELT TENSIONER
(a) Visually check the seal portion of the tensioner for oil leak-
age.
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 to check that it doesn't move.
If the push rod moves, replace the tensioner.
NOTICE:
Never hold the tensioner push rod facing downward.
(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.
4. INSPECT WATER PUMP
(See page CO-7)
