Removal and Installation

REMOVAL

WARNING:

• Situate the vehicle on a flat and solid surface.

• Place chocks at front and back of rear wheels.

• Attach proper slingers and bolts described in EPC if engine slingers are not equipped.

CAUTION:

• Always be careful to work safely, avoid forceful or uninstructed operations.

• Never start working until exhaust system and 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 unavoidable reasons, support at the rear axle jacking point with a 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 point at rear axle, refer to Garage Jack and Safety Stand and 2-Pole Lift.

Inspection

INSPECTION AFTER INSTALLATION

Inspection for Leakage

The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to Fluids and Lubricants.

• Use procedure below to check for fuel leakage.

  • Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.

  • Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

• Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including engine oil and engine coolant.

• Bleed air from lines and hoses of applicable lines, such as in cooling system.

• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the specified level, if necessary.
