●During the operation, make sure that no part interferes
with body side.
●Before and during this lifting, always check if any har-
nesses are left connected.
●During the removal operation, always be careful to pre-
vent vehicle from falling off the lift due to changes in the center of gravity.
●If necessary, support vehicle by setting a jack or equivalent tool at the rear.
28. Remove power steering pump with piping connected from engine. Move it aside on suspension member.
29. Remove front engine mounting and rear engine mounting through-bolts to remove suspension member.
30. Remove starter motor.
31. Separate engine and transaxle. Refer to MT-15, "
TRANSAXLE ASSEMBLY" (M/T models) or AT- 4 1 8 ,
"REMOVAL AND INSTALLATION" (A/T models)
INSTALLATION
Install in the reverse order of removal.
●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 components illustration.
●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, lubrications and working engine oils. 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, lubricants, working
engine oil, fuel and exhaust gas.
