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.

(Engines with toothed belt tension
roller)
Removal
Refer to 6A-21. Toothed Belt and Timing check and removal
steps.
Adjust
1. Loosen the fastening bolt of the toothed belt tension roller.
2. Turn the toothed belt tension roller at adjustment eccentric (1) in the direction of arrow (counterclockwise),
until pointer (2) comes to the right stop.
3. If necessary tighten the fastening bolt of toothed belt tension roller.
4. Rotate the crankshaft twice (720
°) in the engine
rotational direction until marks (2) and (1) align again.
5. Turn the eccentric in the direction of arrow (clockwise)
until pointer (1) and notch (2) are positioned to suit age of
toothed belt.
6. Rotate the crankshaft twice (720 °) in the engine
rotational direction again and correct adjustment if
necessary.
Installation
Refer to 6A-21. Toothed Belt and Timing check and installation
steps.
