Do not allow engine oil to get on mounting insulator. Be careful not to damage mounting insulator.

When installation directions are specified, install parts according to the direction marks on them referring
to figure of components. Refer to EM-78, "
Removal and Installation" .

Make sure that each mounting insulator is seated properly, and tighten mounting bolts and nuts.
INSPECTION AFTER INSTALLATION

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

Use procedure below to make sure there is no fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, make sure there
are no fuel leaks at connection points.
–Start engine. With engine speed increased, check again if there are no fuel leaks at connection points.

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, 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.
