2. Lift with hoist and secure engine in position.
3. Use manual lift table caddy (commercial service tool) or equivalently rigid tool such as transmission jack.
Securely support bottom of suspension member and transmission.
CAUTION:
Put a piece of wood or something similar as the supporting surface, secure a completely stable
condition.
4. Remove front suspension member mounting nuts with power tool. Refer to FSU-6, "
FRONT SUSPEN-
SION ASSEMBLY" .
5. Carefully lower jack, or raise lift to remove engine, transmission
front final drive and front suspension member assembly. When
performing work, observe the following caution:
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.
Separation Work
1. Change engine slinger installing to cylinder head (right bank).
NOTE:
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 check if any harnesses are left connected.
Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-23, "
CHARGING SYSTEM" . Slinger bolts:

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 to the following, and install in the reverse order of removal.
Where positioning pin is used, be sure to securely insert it into the hole of mating part.
When installing engine mount brackets (RH and LH) to cylinder
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
Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.
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 engine coolant, engine oil, working fluid,
fuel and exhaust gas.
Bleed air from passages in pipes and tubes of applicable lines, such as in cooling system.
After cooling down engine, again check amounts of engine coolant, engine oil and working fluid. Refill to
specified level, if necessary.

DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission and front
final drive from engine. Refer to EM-236, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.
Holding ring gear with ring gear stopper (SST).
Loosen mounting bolts diagonally order.
CAUTION:
Do not disassemble drive plate.
Do not place drive plate with signal plate facing down.
When handling signal plate, take care not to damage or
scratch it.
Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove engine rear plate.
3. Lift engine with hoist to install it onto widely use engine stand.
CAUTION:
Use engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for
supporting the engine weight.
If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.
–Intake manifolds (upper and lower); Refer to EM-174, "INTAKE MANIFOLD" .
–Exhaust manifold; Refer to EM-178, "EXHAUST MANIFOLD AND THREE WAY CATALYST" .
–Fuel tube and fuel injector assembly; Refer to EM-188, "FUEL INJECTOR AND FUEL TUBE" .
–A/C compressor; Refer to ATC-139, "Components" .
–Ignition coil; Refer to EM-185, "IGNITION COIL" .
