CAUTION:

Confirm there is no interference with vehicle.

Make sure that all connection points have been discon-
nected.

Keep in mind the center of vehicle gravity changes. If
necessary, use jack(s) to support vehicle at rear jacking
point(s) to prevent it from falling it off the lift. Slinger bolts:

In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member. CAUTION:

Before and during this lifting, always make sure that any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-20, "
CHARGING SYSTEM" .
5. Remove starter motor. Refer to SC-8, "

FRONT FINAL DRIVE ASSEMBLY" .
8. Remove engine mounting insulators (RH and LH) and brackets (RH and LH) from engine with power tool.
9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.

For a location with a positioning pin, insert it securely into hole of mating part.

For a part with a specified installation orientation, refer to component figure in EM-243, "Removal and
Installation" .

When installing engine mounting brackets (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

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 MA-12, "
RECOMMENDED 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 make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant. Slinger bolts:
