POWER STEERING FLUID
POWER STEERING FLUID
PFP:KLF20
Checking Fluid Level
AGS000BV
●
Stop engine before performing a fluid level check.
●
Ensure that the fluid level is between the MAX range and MIN
range.
●
Because the fluid level differs within the HOT range and the
COLD range, check it carefully.
CAUTION:
●
Do not overfill (above the MAX level) because it is cause
of leaks from the cap portion.
●
Do not reuse the drained power steering fluid.
●
Recommended fluid is Genuine NISSAN PSF or equivalent. Do not use NISSAN PSF special and
special and NISSAN matic fluid.
Checking Fluid Leakage
AGS000BW
Check the lines for improper attachment and for leaks, cracks, dam-
age, loose connections, chafing or deterioration.
1.
Run engine at idle speed or about 1,000 rpm.
Make sure that the temperature of fluid in reservoir tank
rises to 50 to 80
°
C (122 to 176
°
F).
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. (It is the possibility that oil pump may be
damaged.)
4.
If fluid leakage at the connectors is noticed, then loosen the flare nut and retighten it.
Air Bleeding from Hydraulic System
AGS000BX
Incomplete air bleeding causes the following to occur. When this happens, bleed the air again.
●
Generation of air bubbles in reservoir tank
●
Generation of clicking noise in oil pump
●
Excessive buzzing in oil pump
NOTE:
Fluid noise may occur in valve or oil pump. This is common when vehicle is stationary or while turning
steering wheel slowly. This does not affect the performance or durability of the system.
1.
Stop engine, and then turn steering wheel fully to right and left several times.
NOTE:
While bleeding air from the hydraulic system, frequently check reservoir tank, add additional fluid up to the
MAX level, if necessary.
2.
Run engine at idle speed, hold steering wheel at each “lock” position for about three seconds.
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. (It is the possibility that
oil pump may be damaged.)
4.
Check generation of air bubbles and cloud in the fluid.
5.
If the air bubbles and the cloud do not fade, stop engine, leave air bleeding behind until the air bubbles
and the cloud fade. Perform the 2nd and the 3rd procedures again.
6.
Stop engine, check fluid level.
HOT
: Fluid temperatures from 50 to 80
°
C (122 to
176
°
F)
COLD
: Fluid temperatures from 0 to 30
°
C (32 to 86
°
F)
