WARNING:

●

Situate vehicle on a flat and solid surface.

●

Place chocks at front and back of rear wheels.

●

For engine 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 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 or separate type lift as best you can. If board-on lift is used for unavoidable
reasons, support at the rear axle jacking point with transmission jack or similar tool before start-
ing work, in preparation for the backward shift of center of gravity.

●

For supporting points for lifting and jacking point at rear axle. Refer to 

GI-40, "Garage Jack and

Safety Stand"
