d. Turn all bolts “90” degrees clockwise (angle tightening).
e. Turn all bolts “90” degrees clockwise again [target: 90 degrees
(angle tightening)].
CAUTION:
Check and confirm the tightening angle by using angle
wrench (SST) and cylinder head bolt wrench (commercial
service tool). Avoid judgment by visual inspection without
SST.
Check tightening angle indicated on angle wrench (SST) indi-
cator plate.
4. After installing cylinder head, measure distance between front
end faces of cylinder block and cylinder head (left and right
banks).
If measurement is outside the specified range, re-install cylin-
der head.
5. Perform steps in reverse order of removal for the following operations.

INSTALLATION
Note to the following, and install in the reverse order of removal.
For a location with a positioning pin, insert it securely into hole of
mating part.
For a part with a specified installation orientation, refer to com-
ponent figure in EM-110, "
2WD MODEL" .
When installing engine mounting bracket on cylinder block,
tighten two upper bolts (shown as A in figure) first. Then tighten
two lower bolts (shown as B in figure). (LH and RH sides)
Tighten rear member mounting bolts in numerical order shown
in figure.
INSPECTION AFTER INSTALLATION
Before starting engine, check the levels of engine coolant, engine oil and working fluid. If less than
required quantity, fill to the specified level.
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 engine coolant, engine oil, working fluid,
fuel and exhaust gas.Slinger bolts:

ASSEMBLY" .
11. Remove LH and RH sides front drive shafts from LH and RH sides knuckles. Refer to FA X - 1 2 , "
FRONT
DRIVE SHAFT" .
Removal Work
1. Use a manual lift table caddy (commercial service tool) or equiv-
alently rigid tool such as a transmission jack. Securely support
bottom of suspension member and transmission.
CAUTION:
Put a piece of wood or something similar as the supporting
surface, secure a completely stable condition.
2. Remove rear member mounting bolt.
3. Remove suspension member mounting bolt and nut. Refer to
FSU-6, "
FRONT SUSPENSION ASSEMBLY" .
4. Carefully lower jack to remove engine, transmission, and sus-
pension member assembly. When performing work, observe the
following:
CAUTION:
Confirm there is no interference with vehicle.
Make sure all connection points have been disconnected.
Keep in mind the center of vehicle gravity changes. If necessary, use jack(s) to support vehicle
at rear jacking point(s) to prevent it from falling it off lift.
Separation Work
1. Install engine slingers into front of RH bank cylinder head and
rear of left bank cylinder head.
2. Remove power steering oil pump from engine side. Refer to PS-31, "
POWER STEERING OIL PUMP" .
3. Remove engine mounting insulator RR under side nut with power tool.
4. Lift with hoist and separate engine and transmission assembly from suspension member.
CAUTION:
Before and during this lifting, always check if any harnesses are left connected.

PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is speci-
fied, do exactly as specified.
Replace with new gasket, packing, oil seal or O-ring.
Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
Release air within route when refilling after draining engine coolant.
After repairing, start engine and increase engine speed to check engine coolant, fuel, oil, and exhaust
systems for leakage.
Parts Requiring Angle TighteningABS006I0
Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap nuts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angle
tightening)
Do not use a torque value for final tightening.
The torque value for these parts are for a preliminary step.
Ensure thread and seat surfaces are clean and coated with engine oil.
Precautions for Liquid GasketABS006I1
REMOVAL OF LIQUID GASKET SEALING
After removing mounting bolts and nuts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.
In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap the areas where liquid gasket is applied.
CAUTION:
If for some unavoidable reason tool such as a flat-blade
screwdriver is used, be careful not to damage the mating
surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.
Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
