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 nuts. Refer to
FSU-5, "On-Vehicle Inspection and Service"

• 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).
• To protect rocker cover against damage caused by tilting of
engine slinger, insert spacer between cylinder head and
engine rear lower slinger, in direction shown in the figure.
NOTE:
Spacer is a component part of engine rear upper slinger
assembly.
2.
Remove power steering oil pump from engine side. Refer to
PS-27, "On-Vehicle Inspection and Service"
.
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
6.
Remove starter motor. Refer to
.
7.
Separate the engine from the transmission assembly. Refer to
AT-241, "Removal and Installation (2WD
.
8.

tool.
9.
Remove rear engine mounting member and engine mounting insulator (rear) from the transmission
assembly.
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
.

ENGINE ASSEMBLY
• When installing engine mounting bracket (RH and LH) on cylinder
block, tighten two upper bolts (shown as “A” in the figure) first.
Then tighten two lower bolts (shown as “B” in the figure).
• Make sure all engine mounting insulators are seated properly, then tighten mounting nuts.
• Tighten rear engine mounting member bolts in numerical order as
shown in the figure.
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
.
• 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.
