POWER STEERING FLUID
ON-VEHICLE MAINTENANCE
POWER STEERING FLUID
Checking Fluid Level
INFOID:0000000005276017
Check fluid level, referring to the scale on the reservoir tank.
Use HOT range for fluid temperatures of 50
°
– 80
°
C (122
°
– 176
°
F).
Use COLD range for fluid temperatures of 0
°
– 30
°
C (32
°
– 86
°
F).
CAUTION:
• Do not overfill.
• Do not reuse any power steering fluid.
• Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to
Checking Fluid Leakage
INFOID:0000000005276018
Check the hydraulic piping lines for improper attachment, leaks,
cracks, damage, loose connections, chafing and deterioration.
CAUTION:
Do not reuse copper washers.
1.
Run the engine until the fluid temperature reaches 50
°
– 80
°
C
(122
°
– 176
°
F) in the reservoir tank. Keep engine speed idle.
CAUTION:
Do not allow steering fluid reservoir tank to go below the
MIN level line. Check tank frequently and add fluid as
needed.
2.
Turn the steering wheel to the right and left several times.
3.
Hold the steering wheel at each “locked” position for five sec-
onds to check for fluid leakage.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that the oil pump may be damaged.)
4.
If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten
connector as this can damage O-ring, washer and connector. Refer to
.
5.
If fluid leakage from the oil pump is noticed, check the oil pump. Refer to
.
6.
Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.
Air Bleeding Hydraulic System
INFOID:0000000005276019
Incomplete air bleeding causes the following:
• Air bubbles in reservoir tank
• Clicking noise in oil pump
• Excessive buzzing in oil pump
When this happens bleed the air again.
NOTE:
When the vehicle is stationary or while the steering wheel is being turned slowly, some noise may be heard
from the oil pump or gear. This noise is normal and does not affect any system.
1.
Check for fluid leakage. Refer to
ST-6, "Checking Fluid Leakage"
.
2.
Start the engine and turn the steering wheel fully to the right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
3.
Run the engine at idle speed. Hold the steering wheel at each "locked" position for three seconds.
CAUTION:
