ENGINE ASSEMBLY
1. Install engine slingers into front of cylinder head (bank 1) (3) and
rear of cylinder head (bank 2) (2).
2. Remove power steering oil pump, power steering piping and power steering bracket from engine and tran-
saxle assembly. Refer to ST-34, "
Exploded View".
3. Disconnect vacuum hoses of front engine mounting insulator and rear engine mounting insulator.
4. Lift with hoist the engine and the transaxle assembly and 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.
5. Remove rear torque rod and rear torque rod bracket.

INSPECTION AFTER INSTALLATION
Inspection for Leakage
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 MA-11, "
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, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including
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.: Vehicle front

DISASSEMBLY AND ASSEMBLY
ENGINE STAND SETTING
SettingINFOID:0000000003802278
NOTE:
Explained here is how to disassemble with engine stand supporting transaxle surface. When using different
type of engine stand, note with difference in steps and etc.
1. Remove the engine assembly from the vehicle. Refer to EM-67, "
Exploded View".
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.
Remove drive plate. Fix crankshaft pulley with the pulley holder (commercial service tool), and remove
mounting bolts.
Loosen mounting bolts in diagonal order.
Check for deformation or damage drive plate.
CAUTION:
Never disassemble drive plate.
Never 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.
3. Remove pilot converter using the pilot bushing puller (SST) as
necessary.
4. Lift the engine with hoist to install it onto the widely use engine stand.
CAUTION:
Use an engine stand that has a load capacity [220 kg (485 lb) or more] large enough for supporting
the engine weight.
If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning the stand.
- Remove intake manifold collector. Refer to EM-28, "
Exploded View".
- Remove intake manifold. Refer to EM-32, "
Exploded View".
- Remove fuel injector and fuel tube assembly. Refer to EM-44, "
Exploded View".
- Remove ignition coil. Refer to EM-49, "
Exploded View".
- Remove rocker cover. Refer to EM-49, "
Exploded View".
- Remove exhaust manifold. Refer to EM-34, "
Exploded View".
- Other removable brackets.

The figure shows an example of widely use engine stand (A)
that can hold mating surface of transaxle with drive plate
removed.
CAUTION:
Before removing the hanging chains, check the engine
stand is stable and there is no risk of overturning.
5. Drain engine oil. Refer to LU-8, "
Draining".
6. Drain engine coolant by removing water drain plugs (A) and (B)
from cylinder block both sides as shown in the figure.
