POWER STEERING – POWER STEERING SYSTEM

PS–3

PS

(e) Start the engine.

(1) Run the engine at idle for a few minutes.

(f)

Turn the steering wheel.
(1) With the engine idling, turn the wheel to the left

or right full lock position and keep it there for 2
to 3 seconds. Then turn the wheel to the
opposite full lock position and keep it there for 2
to 3 seconds (step A).

(2) Repeat step A several times.

(g) Stop the engine.

(h) Check for foaming or emulsification.

Especially, if the system has to be bled twice
because of foaming or emulsification, check for fluid
leakage in the system.

(i)

Check the fluid level.

3.

INSPECT FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the

oil reservoir.
If necessary, add fluid.
Fluid:

ATF "DEXRON" II or III

HINT:
Check that the fluid level is within the HOT level
range in the reservoir tank. If the fluid is cold, check
that it is within the COLD level range.

(c) Start the engine and let it idle.
(d) Turn the steering wheel from lock to lock several

times to raise fluid temperature.
Fluid temperature:

75 to 80

°C (167 to 176°F)

(e) Check for foaming or emulsification.

If any foaming or emulsification is identified, bleed
the power steering system.

(f)

With the engine idling, measure the fluid level in the
oil reservoir.

(g) Stop the engine.
(h) Wait a few minutes and measure the fluid level in

the oil reservoir again.
Maximum fluid level rise:

5 mm (0.20 in.)

If any problems are found, bleed the power steering
system again.

(i)

Check the fluid level.

4.

INSPECT STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube from the vane

pump (See page

PS-8

).

(b) Connect SST as shown in the illustration.

SST

09640-10010 (09641-01010, 09641-01030,
09641-01060)

NOTICE:
Check that the valve of SST is in the open
position.

(c) Bleed the power steering system.
(d) Start the engine and let it idle.
(e) Turn the steering wheel from lock to lock several

times to raise the fluid temperature.
Fluid temperature:

75 to 80

°C (167 to 176 °F)

(f)

With the engine idling, close the valve of SST and
check the reading on SST.
Fluid pressure:

8,300 to 8,800 kPa (85 to 90 kgf/cm

2

, 1,209 to

1,280 psi)

NOTICE:
•

Do not keep the valve closed for more than 10
seconds.

•

Do not let the fluid temperature become too
high.

(g) With the engine idling, fully open the valve.
(h) Measure the fluid pressure at the engine speeds of

1,000 rpm and 3,000 rpm.
Fluid pressure difference:

490 kPa (5 kgf/cm

2

, 71 psi) or less

NOTICE:
Do not turn the steering wheel.

(i)

With the engine idling and valve fully open, turn the
steering wheel to the full lock position.
Fluid pressure:

8,300 to 8,800 kPa (85 to 90 kgf/cm

2

, 1,209 to

1,280 psi)

NOTICE:
•

Do not keep the steering wheel in the full lock
position for more than 10 seconds.

•

Do not let the fluid temperature become too
high.

(j)

Disconnect SST.

(k) Connect the pressure feed tube to the vane pump

(See page

PS-14

).

(l)

Bleed the power steering system.

5.

INSPECT STEERING EFFORT
(a) Center the steering wheel assembly.
(b) Remove the steering pad (See page

RS-345

).

(c) Start the engine and let it idle.
(d) Measure the steering effort in both directions.

Steering effort (Reference):

6.0 N*m (60 kgf*cm, 53 in.*lbf) or less

HINT:
Check the tire type, pressure and contact surfaces
before making a diagnosis.

(e) Install the steering wheel assembly set nut.

Torque: 50 N*m (510 kgf*cm, 37 ft.*lbf)

(f)

Install the steering pad (

RS-346

).
