POWER STEERING FLUID

PERIODIC MAINTENANCE

POWER STEERING FLUID

Checking Fluid Level

INFOID:0000000009483744

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

MA-12, "Fluids and Lubricants"

Checking Fluid Leakage

INFOID:0000000009483745

Check the hydraulic piping lines for improper attachment, leaks,

cracks, damage, loose connections, chafing and deterioration.
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

ST-10

and

ST-19

5. If fluid leakage from the oil pump is noticed, repair or replace the oil pump. Refer to

ST-23, "Disassembly

and Assembly"

6. Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.

CAUTION:

Do not reuse copper sealing washers.

Air Bleeding Hydraulic System

INFOID:0000000009483746

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.
1. With the engine not started, turn steering wheel fully right to left several times. When fluid level is lowered,

refill reservoir. Repeat process until fluid level is stabilized.

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.

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.
