Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal
collision. The SRS system composition which is available to NISSAN MODEL D22 is as follows (The com-
position varies according to the destination and optional equipment.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and
Air Bag Module, see the RS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral Cable and wiring harnesses (except ``SEAT BELT PRE-TENSIONER'')
covered with yellow insulation either just before the harness connectors or for the complete har-
ness are related to the SRS.
PRECAUTIONS
EL-2003

Removal
CAUTION:
lAfter removing the timing chain, do not turn crankshaft
and camshaft separately, or valves will strike piston
heads.
lWhen installing chain tensioners or other sliding parts,
lubricate contacting surfaces with new engine oil.
lApply new engine oil to bolt threads and seat surfaces
when installing camshaft sprockets and crankshaft pul-
ley.
lDo not spill engine coolant on drive belts.
UPPER TIMING CHAIN
1. Remove air duct assembly.
2. Remove vacuum hoses, electrical harness connectors and
harness clamps.
3. Remove power steering drive belt.
4. Remove power steering pump and position it to one side.
5. Remove power steering pump bracket.
6. Remove idler pulley and bracket as well.
7. Remove ignition wires and spark plugs.
8. Set No. 1 piston at TDC on its compression stroke.
9. Remove rocker cover.
Remove in numerical order as shown.
10. Remove camshaft sprocket cover.

11. Remove upper chain tensioner.
(Push in piston and insert a suitable pin into the pin hole.)
12. Wipe off the links of the timing chain next to the timing marks
on the sprockets. Put paint marks on the timing chain, match-
ing them with the timing marks on the cam sprockets and
idler sprocket.
13. Remove cam sprocket bolts, cam sprockets and upper tim-
ing chain.
IDLER SPROCKET
1. Remove upper timing chain.
Refer to ªRemovalº, ªUpper Timing Chainº, EM-2015.
2. Support lower timing chain by using a suitable tool to avoid
chain tensioner spring from coming out.
lThis step is only to be applied when the lower cover is
not being removed.
3. Remove idler sprocket.
LOWER TIMING CHAIN
1. Drain coolant by removing the cylinder block drain plug and
opening the radiator drain cock. Refer to MA section of the
Service Manual.
2. Drain engine oil from drain plug of oil pan.
3. Remove the following parts.
lAlternator drive belt
lA/C compressor drive belt
lCooling fan with coupling
lRadiator shroud
4. Remove A/C compressor and position it to the side. Remove
the idler pulley and bracket as well.
5. Set No. 1 piston to TDC on its compression stroke.
6. Remove distributor.
7. Remove the crankshaft pulley.

WARNING:
lPosition vehicle on a flat and solid surface.
lPlace chocks at front and back of rear wheels.
lDo not remove engine until exhaust system has com-
pletely cooled off.
Otherwise, you may burn yourself and/or fire may break
out in fuel line.
lBefore disconnecting fuel hose, release fuel pressure.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC
SERVICE PROCEDUREº).
lBe sure to hoist engine and transmission in a safe man-
ner.
lFor engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:
lWhen lifting engine, be sure to clear surrounding parts.
Take special care near accelerator wire casing, brake
lines and brake master cylinder.
lIn hoisting the engine, always use engine slingers in a
safe manner.
lFor 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
Removal
1. Drain coolant from engine block and radiator. Refer to MA
section (ªChanging Engine Coolantº, ªENGINE MAINTE-
NANCEº).
2. Release fuel pressure. Refer to EC section (ªFuel Pressure
Releaseº, ªBASIC SERVICE PROCEDUREº).
3. Remove negative battery cable.
4. Remove hood. Refer to BT section.
5. Remove air cleaner and air duct.
6. Remove power steering drive belt, alternator drive belt and
A/C compressor drive belt.
7. Remove radiator. Refer to LC section (ªRadiatorº, ªENGINE
COOLING SYSTEMº).
8. Remove exhaust manifold heat shield.
9. Disconnect exhaust system from exhaust manifold.
10. Remove A/C compressor from bracket. Refer to HA section
(ªCompressor Mountingº, ªSERVICE PROCEDURESº).
11. Disconnect accelerator wire, vacuum hoses, electrical
connectors, heater hoses and vacuum booster hose.

Observe the following precautions to ensure safe and
proper servicing. These precautions are not described in
each individual section.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and
ªSEAT BELT PRE-TENSIONERº used along with a seat belt,
helps to reduce the risk or severity of injury to the driver and front
passenger in a frontal collision. The SRS system composition
which is available to NISSAN MODEL D22 is as follows (The
composition varies according to the destination and optional
equipment.):
Driver air bag module (located in the center of the steering
wheel), front passenger air bag module (located on the instru-
ment panel on passenger side), seat belt pre-tensioner, a diag-
nosis sensor unit, warning lamp, wiring harness and spiral cable.
Information necessary to service the system safely is included in
theRS sectionof this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could
increase the risk of personal injury or death in the event
of a collision which would result in air bag inflation, all
maintenance must be performed by an authorized NIS-
SAN dealer.
lImproper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury
caused by unintentional activation of the system. For
removal of Spiral Cable and Air Bag Module, see the RS
section.
lDo not use electrical test equipment on any circuit
related to the SRS unless instructed to in this Service
Manual. Spiral Cable and wiring harnesses (except
ªSEAT BELT PRE-TENSIONERº) covered with yellow
insulation either just before the harness connectors or
for the complete harness are related to the SRS.
