POWER STEERING FLUID
Revision: 2004 November 2004 FX35/FX45
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelAGS000GT

Stop engine before performing a fluid level check.

Ensure that fluid level is between the MAX range and MIN level.

Because fluid level differs within the HOT range and the COLD
range, check it carefully.
CAUTION:

Do not overfill the Max level.

Do not reuse any used power steering fluid.

Recommended fluid is Genuine NISSAN PSF or equivalent.
Checking Fluid LeakageAGS000GU
Check the hydraulic piping lines for improper attachment and for
leaks, cracks, damage, loose connections, chafing or deterioration.
1. Run engine until fluid temperature reaches 50 to 80° C (122 to
176°F) in reservoir tank. Keep engine speed idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to
check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to PS-31, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating a from steering gear.
Air Bleeding Hydraulic SystemAGS000GV
Incomplete air bleeding causes the following. When this happens, bleed air again.

Generation of air bubbles in reservoir tank.

Generation of clicking noise in oil pump.

Excessive buzzing in oil pump.
NOTE:
When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from
oil pump or gear. This noise is normal and does not affect any system.
1. Stop engine, and then turn steering wheel fully to right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the low-level line. Check tank frequently and
add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about
three seconds. Then check whether a fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals.
CAUTION:
Do not hold steering wheel in the locked position more than 10 seconds. (There is the possibility
that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.HOT : Fluid temperatures from 50 to 80 °C (122 to
176°F)
COLD : Fluid temperatures from 0 to 30°C (32 to 86°F)

On-Vehicle Inspection and ServiceAGS000H2
CHECKING RELIEF OIL PRESSURE (VQ35DE MODELS)
CAUTION:
Before starting work, confirm belt tension is proper.
1. Connect oil pressure gauge (SST) and oil pressure gauge
adapter (SST) between oil pump discharge connector and high
pressure hose and then bleed air from the hydraulic circuit.
2. Start engine. Allow engine to run until tank temperature reaches
50 to 80°C (122 to 176°F).
CAUTION:

Warm up engine with shut-off valve fully opened. If
engine is started with shut-off valve closed, fluid pres-
sure in power steering pump increases to maximum. This
will raise fluid temperature excessively.

Be careful not to contact hose with belt when engine is
started.
3. With engine at idle, close shut-off valve and read the relief oil
pressure.
CAUTION:
Do not close shut-off valve of pressure gauge for more than 10 seconds.
4. After measurement, open shut-off valve slowly.
If relief oil pressure is outside the specification, disassemble and repair oil pump. Refer to PS-33, "
Disas-
sembly and Assembly (VQ35DE models)" .
5. After inspection, disconnect oil pressure gauge (SST) and oil pressure gauge adapter (SST) from hydrau-
lic circuit, connect oil pump discharge connector and high pressure hose. Add fluid and bleed air from
hydraulic circuit thoroughly.
Refer to PS-8, "
Air Bleeding Hydraulic System" .
