24. Remove ground cable between front cover and vehicle.
25. Remove generator. Refer to SC-21
.
26. Remove A/C compressor with piping connected from t he engine. Temporarily secure it on the vehicle side
with a rope to avoid putting load on it. Refer to MTC-80, "
Removal and Installation of Compressor -
MR18DE".
27. Remove the intake manifold to prevent the hanging chain from interfering. Refer to EM-137, "
Compo-
nent".
28. Install engine slinger to cylinder head front left side (A) and rear right side (B) and support the engine position with a hoist.
29. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
30. 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 someth ing similar as the supporting
surface, secure a completely stable condition.
31. Remove torque rod (RH) (1), engine insulator (RH) (2) and engine bracket (RH) (3).
32. Remove engine through bolt-securing nut (C).
33. 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, alw ays check if any harnesses are left connected.
• During the removal operation, alw ays 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 suppor t the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely sup port the engine slingers with a hoist.

ENGINE ASSEMBLY
35. Separate the engine and the transaxle and mount the engine on a suitable engine stand. Refer to
AT-233
(A/T models), CVT-180, "Removal and Installation" (CVT models) or MT-61, "Removal and Installation"
(M/T models).
INSTALLATION
Installation is in the reverse order of removal.
Note the following during installation:
• When installation directions are specified, install parts according to the directions. Refer to EM-197, "
Com-
ponent".
• Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insu-
lator.
• Prior to installing the upper torque rod, apply a light coat of silicone lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tubesurface with a sponge or suitable tool.
• Do not apply excess lubricant.
• 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
• 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-14, "
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 leakage of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
