(2WD A/T models),
and Installation for VQ40DE 4WD Models"
(4WD A/T models).
32. Lift with hoist and secure the engine in position.
33. Remove engine assembly from vehicle, avoiding interference with vehicle body.
CAUTION:
• Before and during this lifting, always check if any harnesses are left connected.
34. Remove the parts that may restrict installation of engine to engine stand.
NOTE:
The procedure is described assuming that you use a engine holding the surface, to which transmission is
installed.
a.
Remove clutch cover and clutch disc (M/T models). Refer to
CL-23, "6M/T : Removal and Installation"
b.
Remove flywheel (M/T models) or drive plate (A/T models).
• Holding crankshaft pulley bolts, lock crankshaft to remove flywheel or drive plate bolts.
• Loosen bolts diagonally.
CAUTION:
• Be careful not to damage or scratch drive plate (A/T
models) and contact surface for clutch disc of flywheel
(M/T models). Especially avoid deforming and damaging
of signal plate teeth (circumference position).
• Do not disassemble drive plate.
• Place the drive plate with signal plate surface facing
other than downward.
• Keep magnetic materials away from 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 fuel tube and fuel injector assembly. Refer to
EM-159, "Removal and Installation"
- Remove intake manifold. Refer to
EM-143, "Removal and Installation"
.
- Remove rocker cover. Refer to
EM-155, "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.
35. Remove generator. Refer to
CHG-21, "Removal and Installation - VQ40DE Models"
.
36. Remove engine mounting insulator bracket (upper) with power tool.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• When replacing an engine or transmission you must make sure the dowels are installed correctly
during reassembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of driv-
etrain components.
Engine slinger torque:
28.0 N·m (2.9 kg-m, 21 ft-lb)

INSPECTION AFTER INSTALLATION
• Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are
lower than required quantity, fill to the specified level. Refer to
MA-16, "For North America: Fluids and Lubri-
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to the fuel piping, check for fuel
leakage at the 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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oil/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to
specified level if necessary.
• Summary of the inspection items:
*Transmission fluid, power steering fluid, brake fluid, etc.
