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.
●
