WARNING:

• Situate the 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.
• Never start working until exhaust system and engine coolant are cool enough.
• If items or work required are not covered by the engine section, refer to 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 rear axle jacking point with transmission jack or similar tool before starting
work, in preparation for the backward shift of center of gravity.

. 

4.

Carefully lower jack, or raise lift to remove the engine, the transmission assembly and front suspension
member. When performing work, observe the following caution:

CAUTION:

• Confirm there is no interference with the vehicle.
• Check that all connection points have been disconnected.
• Keep in mind the center of vehicle gravity changes. If necessary, use jack(s) to support the vehi-

cle at rear jacking point(s) to prevent it from falling it off the lift.
