Parts Requiring Angular Tightening
+Use an angle wrench for the final tightening of the cylinder
head bolts.
+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.
Liquid Gasket Application Procedure
1.Use a scraper to remove old liquid gasket from mating
surfaces and grooves. Also, completely clean any oil
from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+Be sure liquid gasket diameter is as specified.
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.

Removal and Installation
CAUTION:
As the internal mechanism of the idler gear must first of all,
and always, be set by a bolt when removing the timing chain
before removing the fuel injection pump and timing gear,
follow the procedures on EM-1039, ªRemoval of timing
chain after setting idler gearº, ªElectronic controlled fuel
injection pumpº.
+This chapter will deal with the summary of removing the tim-
ing chain before removing the camshaft and cylinder head.
Removal
1. Remove the following parts.
+Engine cover
+Intercooler
+Air inlet pipe
+Throttle body
+Rocker cover
+Spill tube
+Coolant (Drain)
+Radiator upper hose
+Water outlet
+Radiator shroud
+Cooling fan
+Auxilary belt

+Undercover
+Engine oil (Drain)
+Engine coolant (Drain)
+Engine cover
+Intercooler
+Air inlet pipe
+Air cleaner case
+Throttle body
+Swirl and intake air control valve control solenoid valve and
bracket
+Vacuum tank
+Glow plate
+Rocker cover
+Spill tube
+Radiator shrouds (Rear and Lower)
+Cooling fan
+Radiator hose (Upper and Lower)
+Auxiliary belt and auto tensioner.
2. Remove the alternator.
3. Remove the A/C compressor and bracket with piping con-
nected. Move and support it at the LH side of engine bay with
a rope to avoid putting load on piping.
Refer to HA section in Nissan Service Manual (Supplement
I: Publication No. SM0E-Y61AE0E.)
4. Remove the chain cover, timing chain and other parts in
connection.
Before removing timing chain, remove injection pump
sprocket with No.1 cylinder being positioned at TDC. Refer
to the figure.
Refer to ªTIMING CHAINº, EM-1027.
CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
+Do not paint the match mark on the timing chain beforehand
as the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
+Do not drop or hit the sensor.
+Store in a clean place free of iron filings, etc.
+Do not place near any magnetic equipment.
6. Remove the water pump and its stud bolts.
Refer to ªWATER PUMPº in LC section.
7. Remove the water inlet.

+Perform operations for the items other than the engine body,
referring to the applicable sections.
+Refer to MT section and AT section for rear mount.
Removal
+After removing transmission, hoist the engine and remove it.
Preparation
1. Drain coolant from radiator drain plugs.
2. Remove the following parts.
+Engine hood
+Undercover
+Under protector
