PREPARATION

1. Attach thespacer tothe tipofthe radiator platepliers A.
Spacer specification: 1.5mm (0.059 in)thick x18 mm (0.71
in) wide x8.5 mm (0.335 in)long.
2. Make surethatwhen radiator platepliers Aare closed
dimension H"isapprox. 7.6mm (0.299 in).
3. Adjust dimension H"with thespacer, ifnecessary.

• Ifthe radiator corerimscannot becrimped asspecified,
further modification ofthe radiator platepliers Ais
required. Refertothe Technical BulletinLC91-001.

Check valveseats forpitting atcontact surface. Resurface or
replace ifexcessively worn.

• Before repairing valveseats, checkvalveandvalve guide
for wear. Ifthey have worn, replace them.Thencorrect

• Cut with both hands touniform thecutting surface.
REPLACING VALVESEATFORSERVICE PARTS

1. Install newsnap ringonone side ofpiston pinhole.
2. Heat piston to60 to70°C (140to158°F) andassemble piston,
piston pin,connecting rodand new snap ring.

• Align thedirection ofpiston andconnecting rod.
• Numbers stampedonconnecting rodand capcorrespond to
each cylinder.
• After assembly, makesureconnecting rodswings

Precautions forNATS V2.0(ForGasoline Engine
Model)
NATS (Nissan Anti-Theft System)

NATS V2.0willimmobilize theengine ifsomeone triestostart
it without theregistered keyofNATS V2.0.
Both ofthe originally suppliedignitionkeyIDshave been NATS
registered.
The NATS security indicator islocated onthe instrument panel.
The indicator blinkswhentheignition switchisin "OFF" or
"ACC" position. Therefore, NATSwarns outsiders thatthevehi-
cle isequipped withtheanti-theft system.
• When NATSdetects trouble, themalfunction indicatorlamp
(MIL) blinks.
This blinking indicates thattheanti-theft isnot functioning,
so prompt service isrequired.
• When servicing NATS(trouble diagnoses, systeminitialisa-
tion andadditional registration ofother NATS ignition key
IDs), CONSULT hardwareandCONSULT NATSsoftware is
necessary.
Regarding theprocedures ofNATS initialisation andNATS
ignition key
10
registration, refertoCONSULT operation
manual, NATSV2.0.

Therefore, CONSULTNATSsoftware (program cardandoper-
ation manual) mustbekept strictly confidential tomaintain the
integrity ofthe anti-theft function.

• When servicing NATSV2.0(trouble diagnoses, systemini-
tial isation andadditional registration ofother NATS ignition
key IDs),
it
may benecessary tore-register originalkey
identification. Therefore,besure toreceive allkeys from
vehicle owner.
A maximum offour keyIDscan beregistered intoNATS.
• When failing tostart theengine first-time usingthekey of
NATS V2.0,startasfollows.
(1) Turn ignition keyto"OFF".
(2) Wait approx. 5seconds.
(3) Turn ignition keyto"START" againwhilekeeping the
key apart fromanyothers onkey-chain.

SGI285 General
Precautions

• Donot operate theengine foranextended periodoftime
without properexhaust ventilation.
Keep thework areawellventilated andfree ofany flamma-
ble materials. Specialcareshould betaken whenhandling
any flammable orpoisonous materials,suchasgasoline,
refrigerant gas,etc.When working inapit orother enclosed
area, besure toproperly ventilate thearea before working
with hazardous materials.
Do not smoke whileworking onthe vehicle.

Observe thefollowing restricted towingspeeds anddistances.

Speed: Below 50km/h (30MPH)
Distance: Less than65km (40 miles)
CAUTION: Never towanautomatic transaxlemodelfromtherear
(i.e.,

Never towanautomatic transaxlemodelwithrearwheels
raised (withfrontwheels onground) asthis may cause serious
and expensive damagetothe transaxle. Ifitis necessary totow
it with rearwheels raised,always useatowing dollyunder the
