d. Put a paint mark on crankshaft pulley aligning with angle mark
on crankshaft pulley bolt. Then, further retighten bolt by “60”
degrees (equivalent to one graduation)].
11. Rotate crankshaft pulley in normal direction (clockwise when viewed from front) to confirm it turns
smoothly.
12. For the following operations, perform steps in the reverse order of removal.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in the guide may gener-
ate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
INSPECTION AFTER INSTALLATION

Before starting engine, check the levels of engine coolant, lubrications and working fluid. If less than
required quantity, fill to the specified level.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of engine coolant, engine oil and working
fluid, fuel and exhaust gas.

Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.

After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to
specified level, if necessary.
