Toothed Belt and Timing Check

Removal
1. Remove the belts on the bracket for alternator.
2. Remove the fan.
3. Remove the V-belt for power steering.
4. Remove the V-belt for A/C.
5. Remove the fan belt.
6. Remove the fan shroud.

7. Remove the crankshaft pulley while counterholding on
the fastening bolt of toothed belt drive gear.
8. Remove the toothed belt from cover.

Inspection
1. Turn the crankshaft in the engine rotational direction
mark(2) so that the notch (1) on the camshaft gear aligns
with the mark on toothed belt rear cover.
2. Check the timing belt for worn, cracks or oil adhesion.

3. Check that the cast on the water pump aligns with the
counterpart on cylinder block (arrowed).
4. The tension of a toothed belt is correctly adjusted when
the pointer and the center of the notch are aligned(I).
The tension of a run-in toothed belt (regardless of
mileage covered) is correctly adjusted when the pointer
is positioned approx. 4mm (0.16 in.) to the left of the
center of the notch(II).
Check the condition of the run-in toothed belt for
suitability for reuse. Only toothed belts of the toothed
belt tension rollers must be replaced and the source of oil
contamination must be eliminated.
