24. Remove A/C compressor with piping connected from the engine. Temporarily secure it on the vehicle side
with a rope to avoid putting load on it. Refer to MTC-84, "
Removal and Installation of Compressor" .
25. Remove the intake manifold to prevent the hanging chain from interfering. Refer to EM-18, "
Components"
.
26. Install engine slinger to cylinder head front left side (A) and rear
right side (B) and support the engine position with a hoist.
27. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
28. Use a manual lift table caddy (A) or equivalently rigid tool such
as a transmission jack. Securely support bottom of the engine
and the transaxle, and simultaneously adjust hoist tension.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
29. Remove torque rod (RH) (1), engine insulator (RH) (2) and
engine bracket (RH) (3).
30. Remove engine through bolt-securing nut (C).
31. Remove the engine and the transaxle assembly from the vehicle downward by carefully operating sup-
porting tools.
CAUTION:

During the operation, 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 operation, 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.

During operation, securely support the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely support the engine slingers with a hoist.
32. When the engine hoisting is not performed simultaneously, install engine slinger to cylinder head front left
side and rear right side. Refer to EM-73, "
Components" .
33. Remove starter motor. Refer to SC-10, "
STARTING SYSTEM" .
34. Lift with a hoist and position above engine.
35. Separate the engine and the transaxle. Refer to AT - 2 5 3 , "
TRANSAXLE ASSEMBLY" (A/T models), CVT-
207, "TRANSAXLE ASSEMBLY" (CVT models) or MT-15, "TRANSAXLE ASSEMBLY" (M/T models).

INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.

When installation directions are specified, install parts according to the directions. Refer to EM-73, "Com-
ponents" .

Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.

Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
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 MA-11, "
RECOMMENDED 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
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 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.
