1998 NISSAN PICK-UP oil temperature

lAfter disconnecting vacuum or air hoses, attach a tag to
indicate the proper connection.
lUse only the fluids and lubricants specified in this manual.
lUse approved bonding agent, sealants or their equivalents
when required.
lUse tools and recommended special tools where specified
for safe and efficient service repairs.
lWhen repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
lDispose of drained oil or the solvent used for cleaning parts
in an appropriate manner.
WARNING:
To prevent ECM from storing the diagnostic trouble codes,
do not carelessly disconnect the harness connectors which
are related to the ECCS system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC section.
Precautions for Multiport Fuel Injection
System or ECCS Engine
lBefore connecting or disconnecting any harness connector
for the multiport fuel injection system or ECM (Engine Con-
trol Module):
Turn ignition switch to ``OFF'' position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel flows into the catalyst, the
catalyst temperature will be excessively high. To prevent this,
follow the instructions below:
lUse unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
lWhen checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
lDo not run engine when the fuel tank level is low, otherwise
the engine may misfire causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
Precautions for Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
SGI787
PRECAUTIONS
General Precautions (Cont'd)
GI-4

DIESEL ENGINE*:
For Europe: diesel fuel of above 50 cetane
* If two types of diesel fuel are available, use summer or win-
ter fuel properly according to the following temperature con-
ditions.
lAbove þ7ÉC (20ÉF) ... Summer type diesel fuel.
lBelow þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
lDo not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
lDo not use summer fuel at temperature below þ7ÉC
(20ÉF). The cold temperature will cause wax to form in
the fuel. As a result, it may prevent the engine from run-
ning smoothly.
lDo not add gasoline or other alternate fuels to diesel
fuel.
Precautions for Air Conditioning
Use an approved refrigerant recovery unit any time the air con-
ditioning system must be discharged. Refer to HA section
(``HFC-134a (R-134a) Service Procedure'', ``SERVICE PRO-
CEDURES'') for specific instructions.

WARNING:
Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system
is less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove
it.
CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
Failure to do so will cause lubricant to enter the low pressure chamber.
lWhen connecting tubes, always use a torque wrench and a back-up wrench.
lAfter disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.
lWhen installing an air conditioner in the vehicle, connect the pipes as the final stage of the
operation. Do not remove the seal caps of pipes and other components until just before required
for connection.
lAllow components stored in cool areas to warm to working area temperature before removing
seal caps. This prevents condensation from forming inside A/C components.
lThoroughly remove moisture from the refrigeration system before charging the refrigerant.
lAlways replace used O-rings.
lWhen connecting tube, apply lubricant to portions shown in illustration. Be careful not to apply
lubricant to threaded portion.
Lubricant name: Nissan A/C System Oil Type R (Except for the Middle East)
Nissan A/C System Oil Type S (For the Middle East)
Part number: KLH00-PAGR0 (Except for the Middle East)
KLH00-PAGS0 (For the Middle East)
lO-ring must be closely attached to inflated portion of tube.
lAfter inserting tube into union until O-ring is no longer visible, tighten nut to specified torque.
lAfter connecting line, conduct leak test and make sure that there is no leakage from connections.
When the gas leaking point is found, disconnect that line and replace the O-ring. Then tighten
connections of seal seat to the specified torque.

PRECAUTIONS AND PREPARATION
Precautions for Refrigerant Connection
(Cont'd)
HA-5

Refrigeration Cycle
REFRIGERANT FLOW
The refrigerant flow is in the standard pattern. Refrigerant flows through the compressor, condenser, liquid
tank, evaporator and back to the compressor.
The refrigerant evaporation through the evaporator coil is controlled by an externally equalized expansion
valve, located inside the evaporator case.
FREEZE PROTECTION
The compressor cycles on and off to maintain the evaporator temperature within a specified range. When
the evaporator coil temperature falls below a specified point, the thermo control amplifier interrupts the
compressor operation. When the evaporator coil temperature rises above the specification, the thermo con-
trol amplifier allows compressor operation.
REFRIGERANT SYSTEM PROTECTION
Triple-pressure switch
The triple-pressure switch is located on the liquid tank. If the system pressure rises or falls out of
specifications, the switch opens to interrupt compressor clutch operation.
Fusible plug
Open at temperature above 105ÉC (221ÉF), thereby discharging refrigerant to the atmosphere. If this plug
is melted and opened, check the refrigerant line and replace liquid tank.
