Removal Work

1.

Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of suspension member and the transmission assembly.

CAUTION:

Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.

2.

Remove rear engine mounting member bolts.

3.

Remove front suspension member mounting bolts and nuts. Refer to 

FSU-19, "Exploded View"

. 

4.

Carefully lower jack, or raise lift to remove the engine, the transmission assembly and front suspension
member. When performing work, observe the following caution:

CAUTION:

• Confirm there is no interference with the vehicle.
• Make sure that 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.

Separation Work

1.

Install engine slingers into front of cylinder head (right bank) and
rear of cylinder head (left bank).

ENGINE ASSEMBLY

• To protect rocker cover against damage caused by tilting of

engine slinger, insert spacer between cylinder head and
engine rear lower slinger (3), in direction shown in the figure.

NOTE:
Spacer (2) is a component part of engine rear upper slinger
assembly.

2.

Remove power steering oil pump from engine side. Refer to 

ST-44, "WITHOUT 4WAS : Exploded View"

(without 4WAS models) or 

ST-49, "WITH 4WAS : Exploded View"

 (with 4WAS models).

3.

Remove engine mounting insulators (RH and LH) under side nuts with power tool.

4.

Lift with hoist and separate the engine and the 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.

5.

Remove alternator. Refer to 

CHG-24, "2WD : Exploded View"

 (2WD models) or 

CHG-26, "AWD :

Exploded View"

 (AWD models).

6.

Remove starter motor. Refer to 

STR-15, "Exploded View"

.

7.

Separate the engine from the transmission assembly. Refer to 

TM-26, "Exploded View"

 (M/T models) or

TM-275, "2WD : Exploded View"

 (A/T models).

8.

Remove each engine mounting insulator and each engine mounting bracket from the engine with power
tool.

INSTALLATION

Note the following, and install in the reverse order of removal.
• Do not allow engine mounting insulator to be damage and careful no 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-77, "2WD : Exploded

View"

.

• When installing engine mounting bracket (RH and LH) on cylinder

block, tighten two upper bolts [shown as (B) in the figure] first.
Then tighten two lower bolts [shown as (C) in the figure].

• Make sure all engine mounting insulators are seated properly, then tighten mounting nuts.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

The following 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 

GI-15, "Recommended Chemical Products and Sealants"

.

• 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 leak-

age 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 includ-

ing 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.

Summary of the inspection items:

*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

WARNING:

• Situate the vehicle on a flat and solid surface.
• Place chocks at front and back of rear wheels.
• For engines 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 type or separate type lift as best you can. If board-on type is used for unavoid-

able reasons, support at rear axle jacking point with transmission jack or similar tool before starting
work, in preparation for the backward shift of center of gravity.
