WARNING:
 Situate vehicle on a flat and solid surface.
 Place chocks at front and back of rear wheels.
 For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.
 Do not start working until exhaust system and coolant are cool enough.
 If items or work required are not covered by the main engine section, follow the procedures in the
applicable sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking rear axle, refer to GI-48, "
Garage Jack and Safety Stand
and 2-Pole Lift" or GI-49, "Board-On Lift".

INSTALLATION
Installation is in the reverse order of removal.
 Do not allow 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
exploded views.
 Make sure that each mounting insulator is seated properly, and tighten mounting bolts and nuts.
InspectionINFOID:0000000001381506
INSPECTION AFTER INSTALLATION
 Before starting engine check the levels of coolant, lubricants and oils. Fill to the specified level.
