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)

PRECAUTIONS

PRECAUTIONSPFP:00001
PrecautionsADS000K2
CAUTION:

Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and system-
atic operations.

Check for the correct installation status prior removal or disassembly. When matching marks are
required, be sure they do not interfere with the function of the parts they are applied to.

Carry out an overhaul in a clean work place, Using a dust proof room is recommended.

Before disassembly, using steam or white gasoline, completely remove sand and mud from the
exterior the unit, preventing them from entering into the unit during disassembly or assembly.

Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a
malfunction is detected, replace it with a new one.

Normally replace lock pins, oil seals, and bearings with new ones every times they are removed.

In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-
side. If tightening sequence is specified, observe it.

Clean and flush the parts sufficiently and blow them dry.

Be careful not to damage the sliding surfaces and mating surface.

When applying sealant, remove the old sealant from the mounting surface; then remove any mois-
ture, oil, and foreign materials from the application and mounting surfaces.

Always use shop paper for cleaning the inside of components.

Avoid using cotton gloves or a shop cloth to prevent entering of lint.

During assembly, observe the specified tightening torque, and new differential gear oil, Vaseline,
or multi-purpose grease, as specified for each vehicle, when necessary.
