POWER STEERING FLUID
InspectionINFOID:0000000009461251
FLUID LEVEL
Check power steering fluid level at the scale on reservoir tank cap
indicator.
• Check power steering fluid level with engine stopped and the fluid temp between 0 – 30 ° C (32 – 86 ° F).
• Power steering fluid level should be between the hatching area of the indicator on the power steering reservoir tank cap.
CAUTION:
• Do not overfill.
• Do not reuse used power steering fluid.
• Recommended power steering fluid is Genuine NISSAN E-
PSF or equivalent. Refer to MA-11, "FOR USA AND CANADA :
Fluids and Lubricants".
FLUID LEAKAGE
Check the power steering hydraulic system for leaks, cracks, dam-
age, loose connections, chafing or det erioration. Repair or replace
as necessary.
1. Start engine and allow engine to 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. Damage to power steering oil pump may
occur.
4. If power steering fluid leakage at connections is noticed, loosen flare nut and retighten.
CAUTION:
Do not over tighten flare nut as damage to O-ring and connection can occur.
5. If power steering fluid leakage from the power steer ing oil pump is noticed, repair connection or replace
power steering oil pump. Refer to ST-15, "Inspection"
.
6. Check steering gear boots for accumulation of power st eering fluid. Power steering fluid indicates a leak
from the power steering gear, replace as necessary. Refer to ST-36, "Removal and Installation"
.

CONDITION OF INSTALLATION
• Check installation condition of power steering gear assembly, front suspension, front drive shaft and steering
column.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Verify that the power steering gear nuts are tightened to specification. Refer to ST-36, "Exploded View"
.
STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steer ing wheel to the left and right lightly. Measure steer-
ing wheel movement on the outer circumference of the steering wheel when it is turned to the point where
tires start moving.
NEUTRAL POSITION ON STEERING WHEEL
• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
25, "Wheel Alignment (Unladen*1)".
1. Turn tires straight ahead, check if st eering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of power steering gear outer sockets, then adjust tie-rods by the same
amount in the opposite direction.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature.
4. Verify that the tires are inflated to the specified pressure. Refer to WT-60, "Tire"
.
5. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.
6. If steering wheel turning force is out of specification, inspect steering column. Refer to ST-18, "Inspection"
.
7. If steering column meets specification, inspect steering gear. Refer to ST-20, "Inspection"
.

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal be fore starting the following procedure.
1. Connect the Tool between oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-30, "Air Bleeding Hydraulic Sys-
tem".
2. Start engine. Run engine until power steering fluid temperature reaches 50 ° - 80 °C (122 ° - 176 °F).
CAUTION:
• Leave the valve of the hydraulic pressure gauge fully open while starting and ru nning engine. If engine is
started with the valve closed, th e hydraulic pressure in oil
pump goes up to the relief pressure along with unusual
increase of fluid temperature.
• Be sure to keep hose clear of belts and other parts when engine is started.
3. Fully close the Tool valve with engine at idle and measure the relief oil pressure.
CAUTION:
Do not keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraul ic circuit, then add fluid and bleed air. Refer to ST-30,
"Air Bleeding Hydraulic System".

DRAINING
1. Disconnect the high and low pressure piping from power steering gear.
2. Drain power steering fluid into a suitable container.
REFILLING
1. Fill power steering reservoir while checking power steering fluid level.
2. Bleed air from power steering hydraulic system. Refer to ST-30, "Air Bleeding Hydraulic System"
.
3. Check for power steering fluid leaks.
Air Bleeding Hydraulic SystemINFOID:0000000009461267
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, excessive noise in the power steering oil pump will be present.
1. Make sure engine is off.
2. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles are no longer being generated in the reservoir.
3. When the power steering fluid level lowers, refill the reservoir. CAUTION:
Do not allow the power steerin g fluid level to drop below
the hatching area.
4. Repeat steps one and two until the power steering fluid level stabilizes.
5. Start the engine and run at idle.
6. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles or fluid discoloration are no longer being generated in the reservoir.
7. When the power steering fluid level lowers, refill the reservoir.
8. Stop the engine.
9. Verify proper power steering fluid level. Power steering fluid level should be between the hatching area of the indicator on
the power steering reservoir tank cap.
