2. Verify that the camshaft pulley marks are aligned with the
cylinder head cover marks.
3. Install the timing belt so that there is no looseness at the
tension side.
Caution
l Do not turn the crankshaft counterclockwise.
4. Turn the crankshaft two turns clockwise, and align the tim-
ing belt pulley mark with the timing mark.
5. Verify that the camshaft pulley marks are aligned with the
cylinder head cover mark.
if not aligned, remove the timing belt and repeat from ten-
sioner installation.
6. Loosen the tensioner lock bolt to apply tension to the tim-
ing belt.
Caution
l Be sure not to apply tension other than that of the
tensioner spring.
7. Tighten the tensioner lock bolt.
Tightening torque:
19-25 N#m (1.9-2.6 m-kg, 14-19 ft-lb)
8. Turn the crankshaft 2 turns clockwise and verify that the
timing marks are correctly aligned.
9. Measure the timing belt deflection by applying moderate
pressure (96 N, 10 kg, 22 lb) midway between the crank-
shaft pulley and the camshaft pulley.
If the timing belt deflection is not correct, temporarily se-
cure tensioner lock bolt so the spring is fully extended and
repeat steps 4-8 above or replace the tensioner spring.
Deflection:
11 .O-13.0mm (0.43-0.51 In) at 96 N (10 kg, 22 lb)

ENGINE OIL
Inspection
1. Be sure the vehicle is on level ground.
2. Warm up the engine to normal operating temperature and
stop it.
3. Wait for 5 minutes.
4. Remove the oil level gauge and check the oil level and con-
dition.
5. Add or replace oil if necessary.
Note
l The distance between the L and F marks on the level
gauge represents 0.8 liter (0.85 US qt, 0.70 Imp qt).
ENGINE COOLANT
Inspection
Coolant level (engine cold)
Warning
l Never remove the radiator cap while the engine is
hot.
l Wrap a thick cloth around the cap when removing it.
1. Verify that the coolant level is near the radiator filler neck.
2. Remove the coolant level gauge and check the coolant level.
3. Add coolant if necessary.
Coolant quality
1. Verify that there is no buildup of rust or scale around the
radiator cap or radiator filler neck.
2. Verify that the coolant is free of oil.
3. Replace the coolant if necessary.
DRIVE BELT
Inspection
1. Check the drive belts for wear, cracks, and fraying. Replace
if necessary.
2. Verify that the drive belts are correctly mounted on the
pulleys.
