ENGINE ASSEMBLY

• Confirm there is no interference with the vehicle.
• Check 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.

3.

Lift with hoist the engine and the transaxle assembly and front suspension member.

CAUTION:

• Before and during this lifting, always check if any harnesses are left connected.
• Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.

4.

Remove rear torque rod and rear torque rod bracket.

5.

Remove each engine mounting insulator and each engine mounting bracket from engine.

6.

Lift with hoist and separate the engine and the transmission assembly from front suspension member.

7.

Remove starter motor. Refer to 

STR-18, "Removal and Installation"

.
