BLEEDING
1. CHECK FLUID LEVEL (See page SR±5)
2. JACK UP FRONT OF VEHICLE AND SUPPORT IT
WITH STANDS
3. TURN STEERING WHEEL
With the engine stopped, turn the wheel slowly from lock to lock
several times.
4. LOWER VEHICLE
5. START ENGINE
Run the engine at idle for a few minutes.
6. TURN STEERING WHEEL
(a) With the engine idling, turn the wheel left or right to the 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.
(b) Repeat (a) several times.
7. STOP ENGINE
8. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of foam-
ing or emulsification, check for fluid leaks in the system.
9. CHECK FLUID LEVEL (See page SR±5)

INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the reser-
voir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
When the fluid is hot, check that the fluid level is within the HOT
range on the reservoir/reservoir cap dipstick.
If the fluid is cold, check that it is within the COLD range.
(c) Start the engine and run at idle.
(d) Turn the steering wheel from the lock position to the other
side of lock position several times to boost fluid tempera-
ture.
Fluid temperature: 80°C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed the air from the power
steering system (See page SR±4).
(f) With the engine idling, measure the fluid level in the reser-
voir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed the air from the power steering sys-
tem (See page SR±4).
(i) Check the fluid level.

2. CHECK STEERING FLUID PRESSURE
(a) Remove the air cleaner assembly with the air cleaner
hose connected (See page SR±26).
(b) Disconnect the pressure feed tube from the PS vane
pump (See page SR±26).
(c) Connect SST, as shown in the illustration.
SST 09640±10010 (09641±01010, 09641±01030,
09641±01060)
NOTICE:
Check that the valve of the SST is in the open position.
(d) Bleed the power steering system (See page SR±4).
(e) Start the engine and run at idle.
(f) Turn the steering wheel from the lock position to the other
side of lock position several times to boost fluid tempera-
ture.
Fluid temperature: 80 °C (176 °F)
(g) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
8,336 kPa (85 kgf/cm
2, 1,209 psi)
NOTICE:

Do not keep the valve closed for more than 10 se-
conds.

Do not let the fluid temperature become too high.
(h) With the engine idling, open the valve fully.
(i) Measure the fluid pressure at engine speeds of 1,000 rpm
and 3,000 rpm.
Difference in fluid pressure:
490 kPa (5 kgf/cm
2, 71 psi) or less
NOTICE:
Do not turn the steering wheel.

(l) Connect the pressure feed tube (See page SR±36).
(m) Install the air cleaner assembly with air cleaner hose (See
page SR±36).
(n) Bleed air from the power steering system
(See page SR±4).

3. INSPECT FLOW CONTROL VALVE
(a) Coat the valve with power steering fluid and check that it
falls smoothly into the valve hole under its own weight.
(b) Check the flow control valve for leakage.
Close one of the holes and apply compressed air 392 to
490 kPa (4 to 5 kgf/cm
2, 57 to 71 psi) into the opposite
side, and confirm that air does not come out from the end
holes.
If necessary, replace the valve with the one having the same let-
ter inscribed on the front housing.
Inscribed mark: A, B, C, D, E or F
