CAUTION:
Confirm there is no interference with vehicle.
Make sure that all connectio n points have been discon-
nected.
Keep in mind the center of veh icle gravity changes. If nec-
essary, use jack(s) to support vehicle at rear jacking
point(s) to prevent it from falling it off the lift.

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 "Removal and Installation".
When installing engine mounting brackets (RH and LH) on cylinder
block, tighten two upper bolts (show n 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 incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-9, "
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 leak-
age at connection points.
- Start engine. With engine speed increased, che ck 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 leak age of fuel, exhaust gases, or any oil/fluids includ-
ing engine oil and engine coolant.
Bleed air from lines and hoses of applic able 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.

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 separa te front suspension member, transmission and front
final drive from engine. Refer to EM-237, "
Component".
2. Remove the parts that may restrict installation of engine to widely use engine stand. NOTE:
The procedure is described assuming that you use wi dely 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 240 kg ( 529 lb) or more] large enough for
supporting the engine weight.
If the load capacity of stand is not adequate, remo ve the following parts beforehand to reduce the poten-
tial risk of overturning stand.
- Intake manifolds (upper and lower): Refer to EM-175, "
Component".
- Exhaust manifold: Refer to EM-179, "
Component".
- Fuel tube and fuel injector assembly: Refer to EM-190, "
