POWER STEERING FLUID
Revision: 2007 April2007 M35/M45
POWER STEERING FLUIDPFP:KLF20
Checking Fluid LevelNGS000D5

Check fluid level with engine stopped.

Make sure that fluid level is between MIN and MAX.

Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:

The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.

Do not reuse drained power steering fluid.

Recommended fluid is Genuine Nissan PSF or equiva-
lent.
Checking Fluid LeakageNGS000D6
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80° C (122
to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the 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 overtighten 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-30, "
POWER STEERING OIL
PUMP" .
6. Check steering gear boots for accumulation of fluid indicating from steering gear.
Air Bleeding Hydraulic SystemNGS000D7
If air bleeding is not complete, the following symptoms can be observed.

Bubbles are created in reservoir tank.

Clicking noise can be heard from oil pump.

Excessive buzzing in the oil pump.
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
Filling reservoir tank with fluid so as not to lower fluid level below the MIN line while steering
wheel turning.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and while contamination.HOT : Fluid temperature 50 - 80 °C (122 - 176°F)
COLD : Fluid temperature 0 - 30°C (32 - 86°F)

ASSEMBLY
NOTE:
Secure oil pump in a vise if necessary.
CAUTION:
Use copper plates when securing in a vise.
1. Apply recommended grease to oil seal lips (1). Apply recom-
mended fluid to around oil seal, and then install oil seal to body
assembly.
2. Apply recommended fluid to drive shaft, and press drive shaft
into body assembly, then install snap ring.
3. Apply recommended fluid to O-ring, and then install O-ring into
body assembly.
4. Install side plate to body assembly.
5. Install dowel pin (3) into dowel pin hole (A), and then install cam
ring (2) pointing it's D
1 side toward the body assembly (1) side
as shown in the figure.

When installing cam ring, turn carved face with a letter E (B)
of it to rear cover.
CAUTION:
Do not confuse the assembling direction of cam ring. If
cam ring is installed facing the incorrect direction, it may
cause oil pump operation malfunction.
6. Install rotor to body assembly.

System DescriptionNHS0007Y

Pre-crash seat belt system is adapted to front seat belts RH/LH.

When the pre-crash seat belt control unit judges the emergency braking operation, it gives the sense of
security by the motor built into the pre-crash seat belt retracting the shoulder belt and suppressing the
crew's posture change. Also, it eases the damage of the collision.
