INSTALLATION

Installation is in the reverse order of removal.

NOTE:

Tighten transmission bolts to specification. Refer to 

TM-26, "Removal and Installation"

 (M/T), 

TM-259,

"Removal and Installation"

 (CVT).

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 check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

• Start engine. With engine speed increased, check again for fuel leakage 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.
