ENGINE ASSEMBLY
4. Remove engine mounting insulator (RH) (1), engine mounting
bracket (RH) (2) and engine mounting stay (3).
5. Remove engine mounting through bolt-securing nut (A).
6. Carefully lower jack, or raise lift to remove the engine and the transaxle assembly.
CAUTION:
 Make sure that no part interferes with the vehicle side.
 Before and during this lifting, always check if any harnesses are left connected.
 During the removal, always be careful to prevent the vehicle from falling off the lift due to
changes in the center of gravity.
 If necessary, support the vehicle by setting jack or suitable tool at the rear.
Separation
1. Remove starter motor. Refer to STR-13, "Removal and Installation".
2. Lift with a hoist and separate the engine from the transaxle assembly. Refer to EM-89, "
Exploded View".
INSTALLATION
Installation is in the reverse order of removal.
 Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
 Make sure that each mounting insulator is seated properly, and tighten mounting nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
 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-19, "
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 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.

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 the engine and the transaxle assembly from the vehicle, and separate the transaxle from the
engine. Refer to EM-89, "
Exploded View".

 Secure flywheel with a stopper plate [SST: KV11105210], and remove mounting bolts.
CAUTION:
 Never disassemble flywheel.
 Never place flywheel 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.
4. Lift the engine with a hoist to install it onto widely use engine stand.
CAUTION:
 Use the engine stand that has a load capacity [approximately 135 kg (298 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 poten-
tial risk of overturning stand.
- Intake manifold: Refer to EM-29, "
Exploded View".
- Exhaust manifold: Refer to EM-32, "
Exploded View".
- Rocker cover: Refer to EM-47, "
Exploded View".
NOTE:
The figure shows an example of widely use engine stand that
can support mating surface of transaxle with flywheel removed.
CAUTION:
Before removing the hanging chains, make sure the engine
stand is stable and there is no risk of overturning.
5. Drain engine oil. Refer to LU-7, "
Draining".
6. Drain engine coolant by removing water drain plug (1) from
inside of the engine.
Use Genuine Liquid Gasket or equivalent.
