29. Lift using a hoist and secure the engine in position.
30. Remove the engine assembly from the vehicle, avoid interfer-
ence with the vehicle body.
CAUTION:
• Before and during lifting, always check if any harnesses are left connected.
31. Remove the parts that may restrict installation of the engine to the engine stand.
NOTE:
This procedure is described assuming that you use an engine stand mounting to the surface to which the
transmission mounts.
a. Before removing the drive plate, put a match mark (A) on the
crankshaft and drive plate for alignment during installation.
b. Remove the drive plate.
• Holding the crankshaft pulley bolt, lock the crankshaft to remove the drive plate bolts.
• Loosen the bolts diagonally.
CAUTION:
• Be careful not to damage the drive plate. Especially
avoid deforming and damaging of the signal plate teeth
(circumference position).
• Place the drive plate with the signal plate surface facing
other than downward.
• Keep magnetic materials away from the signal plate.
CAUTION:
Use an engine stand that has a load capacity [approximately 240kg (529 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 the fuel tube and fuel injector assembly. Refer to
EM-41, "Removal and Installation"
- Remove the intake manifold. Refer to
EM-26, "Removal and Installation"
- Remove the ignition coil. Refer to
EM-38, "Removal and Installation"
.
- Remove the rocker cover. Refer to
EM-39, "Removal and Installation"
.
- Other removable brackets.
CAUTION:
Before removing the hanging chains, make sure the engine stand is stable and there is no risk of
overturning.

INSTALLATION
Installation is in the reverse order of removal.
• Tighten engine mounting bracket bolts in numerical order as
shown.
CAUTION:
• When replacing an engine or transmission you must make sure the dowels are installed correctly
during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of driv-
etrain components.
INSPECTION AFTER INSTALLATION
• 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
GI-15, "Recommended Chemical Products and Sealants"
.
• 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 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 oils/fluids including engine oil and engine coolant. Refill to specified
level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
