POWER STEERING FLUID

POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelEGS0004B

Check the fluid level with the engine OFF.

Check that fluid level is between MAX and MIN marks on tank.
Fluid level should not exceed MAX mark. Excessive fluid will
cause fluid to leak from cap.

Note that fluid level can change depending on temperature of
fluid. HIGH and LOW marks are shown on tank to indicate the
proper level at high temperature and low temperature respec-
tively.
CAUTION:

Never reuse drained power steering fluid.

Use DEXRONTM III or equivalent. Never use Nissan Power Steering Fluid Special, Nissan Matic
Fluid C, or D.
Checking Fluid LeakageEGS0004C
Check hydraulic connections for any leakage, crack, damage, loose-
ness, or wear.
1. Run engine until fluid temperature reaches 50 to 80°C (122 to
176°F) in reservoir tank. Keep engine speed at idle.
2. Turn steering wheel several times from stop to stop.
3. Turn the steering wheel clockwise or counter clockwise until it
reaches the stop and hold it for five seconds. Check for fluid
leak.
CAUTION:
Do not hold steering wheel at stop for 15 seconds or longer.
Otherwise, pump may be damaged.
4. If any leak is found on joint, loosen and retighten flair nut. Excessive tightening may damage O-ring,
washer, or connector.
Bleeding Hydraulic SystemEGS0004D
1. Lift vehicle.
2. Fill tank up to MAX mark. Turn steering wheel several times from stop to stop. Add fluid if fluid level goes
down. Repeat this step until there is no fluid decrease and no bubble in tank.
3. Start engine and repeat step above with engine at idle. Continue step until no decrease in fluid happens.
If bleeding is not complete, following symptoms can be observed.

Bubbles are created in reservoir tank.

Rattling noise can be heard from oil pump.

Whining noise can be heard from oil pump.
Turn steering wheel slowly or stop vehicle. Sound of fluid movement may be heard from gear valve and
pump. This sound has nothing to do with steering performance or durability.HOT : Oil temperature 50 to 80°C (122 to 176°F)

On-Vehicle Inspection and ServiceEGS000AF
OIL PUMP PULLEY HYDRAULIC PRESSURE INSPECTION
Before starting following procedure, check tension of belt.
1. Raise vehicle. Connect oil pressure gauge between oil pump
discharge connector and high pressure hose. Then bleed the
hydraulic circuit.
2. Start engine. Run engine until oil temperature reaches 50°C -
80°C (122 - 176°F)
CAUTION:

Leave valve of hydraulic pressure gauge fully open while
starting and running engine. If engine is started with
valve closed, hydraulic pressure in oil pump goes up.
This will relief pressure along with abnormal increase of
oil temperature.

Care must be taken to keep hose clear of belt and other parts when engine is started.
3. Fully close hydraulic pressure gauge valve with engine at idle. Measure relief pressure.
4. After measurement, open valve slowly.
CAUTION:
Never keep valve closed for 15 seconds or longer.

If relief pressure is outside specification, disassemble and service oil pump. Refer to PS-25, "Disas-
sembly and Assembly(QR20DE and QR25DE engine models)" .
5. After inspection, remove oil pressure gauge from hydraulic circuit. Add fluid. Be sure to bleed the system
completely. Refer to PS-6, "
Bleeding Hydraulic System"

REMOVAL
1. Loosen adjusting screw and oil pump mounting bolt. Then, remove belt.
2. Remove union bolt and hose for oil pump.
3. Remove oil pump bracket attaching bolt.
4. Remove oil pump from vehicle.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.

After installation, adjust belt tension. Refer to EM-13, "DRIVE BELTS" .

After installation, be sure to bleed system. Refer to PS-6, "Bleeding Hydraulic System" . Relief pressure specification:

Do not attempt to disassemble driver air bag module.

Do not use old bolts after removal; replace with new bolts.

Do not expose the driver air bag module to temperatures
exceeding 90°C (194°F).

Replace air bag module if it has been dropped or sustained

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.

O-ring must be closely attached to dented portion of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.With gasoline engine

REFRIGERATION SYSTEM

REFRIGERATION SYSTEMPFP:KA990
Refrigerant CycleEJS000TD
REFRIGERANT FLOW
The refrigerant flows in the standard pattern, that is, through the compressor, the condenser with liquid tank,
through the 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 (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
Under usual operating conditions, when the A/C is switched on, the compressor runs continuously, and the
evaporator pressure, and therefore, temperature is controlled by the V-6 variable displacement compressor to
prevent freeze up.
Refrigerant System ProtectionEJS000TE
REFRIGERANT PRESSURE SENSOR (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
The refrigerant system is protected against excessively high- or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank. If the system pressure rises above, or falls below the specifications, the refriger-
ant pressure sensor detects the pressure inside the refrigerant line and sends the voltage signal to the ECM.
ECM makes the A/C relay go OFF and stops the compressor when pressure on the high-pressure side
detected by refrigerant pressure sensor is over about 2,746 kPa (27.46 bar, 28 kg/cm
2 , 398 psi), or below
about 134 kPa (1.34 bar, 1.4 kg/cm
2 , 20 psi).
DUAL-PRESSURE SWITCH (WITH DIESEL ENGINE: DKV-11G COMPRESSOR)
The refrigerant system is protected against excessively high- or low-pressures by the dual-pressure switch,
located on the liquid tank. If the system pressure rises above or falls below the specifications, the dual-pres-
sure switch opens to interrupt the compressor operation.
PRESSURE RELIEF VALVE (WITH GASOLINE ENGINE: CWV-615M COMPRESSOR)
The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
When the pressure of refrigerant in the system increases to an unusual level [more than 3,727 kPa (37.27 bar,
38 kg/cm
2 , 540 psi)], the release port on the pressure relief valve automatically opens and releases refriger-
ant into the atmosphere.

LUBRICANT

LUBRICANTPFP:KLG00
Maintenance of Lubricant Quantity in CompressorEJS000TH
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:

Lack of lubricant: May lead to a seized compressor

Excessive lubricant: Inadequate cooling (thermal exchange interference)

LUBRICANT RETURN OPERATION
Adjust the lubricant quantity according to the test group shown below.
1. CHECK LUBRICANT RETURN OPERATION
Can lubricant return operation be performed?

A/C system works properly.

There is no evidence of a large amount of lubricant leakage.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant return operation.
