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-

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.

(j) With the engine idling and the valve fully opened, turn the
steering wheel left or right to the full lock position.
Minimum fluid pressure:
8,336 kPa (85 kgf/cm
2, 1,209 psi)
NOTICE:

Do not maintain the lock position for more than 10 se-
conds.

Do not let the fluid temperature become too high.
(k) Disconnect the SST.

(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).

1. TURN AIR CONDITIONING SWITCH OFF
2. CHECK IDLE±UP
(a) Start the engine and run it at idle.
(b) Fully turn the steering wheel.
(c) Check that the engine speed decrease when the vacuum
hose of the air control valve is pinched.
(d) Check that the engine speed increase when the hose is
released.

STEERING WHEEL
INSPECTION
1. CHECK STEERING WHEEL FREE PLAY
(a) Stop the vehicle and face the tires straight ahead.
(b) Gently rock the steering wheel up and down with a finger,
and check the steering wheel free play.
Maximum free play: 30 mm (1.18 in.)
2. CHECK STEERING EFFORT
(a) Center the steering wheel.
(b) Remove the steering wheel pad (See page SR±12).
(c) Start the engine and run at idle.
(d) Measure the steering effort in both directions.
Steering effort (Reference):
4.9 N´m (50 kgf´cm, 43 in.´lbf)
HINT:
Check tire type, pressure and contact surface before making
your diagnosis.
(e) Tighten the steering wheel set nut.
Torque: 50 N´m (510 kgf´cm, 37 ft´lbf)
(f) Install the steering wheel pad (See page SR±23).

REPAIR PROCEDURES
HINT:
This is the repair procedure for steering off center.
1. INSPECT STEERING WHEEL OFF CENTER
(a) Apply masking tape on the top center of the steering
wheel and steering column upper cover.
(b) Drive the vehicle in a straight line for 100 meters at a
constant speed of 35 mph (56 km/h), and hold the steer-
ing wheel to maintain the course.
(c) Draw a line on the masking tape as shown in the illustra-
tion.

(d) Turn the steering wheel to its straight position.
HINT:
Refer to the upper surface of the steering wheel, steering spoke
and SRS airbag line for the straight position.
(e) Draw a new line on the masking tape of the steering wheel
as shown in the illustration.
(f) Measure the distance between the 2 lines on the masking
tape of the steering wheel.
(g) Convert the measured distance to steering angle.
Measured distance 1 mm (0.04 in.) = Steering angle
approximately 1 deg.
HINT:
Make a note of the steering angle.
2. ADJUST STEERING ANGLE
(a) Draw a line on the RH and LH tie rod and rack ends where
it can easily be seen.
(b) Using a paper gauge, measure the distance from RH and
LH tie rod ends to the rack end screws.
HINT:

Measure the RH side and LH side.

Make a note of the measured values.
(c) Remove the RH and LH boot clips from the rack boots.
(d) Loosen the RH and LH lock nuts.
(e) Turn the RH and LH rack end by the same amount (but
in different directions) according to the steering angle.
1 turn 360 deg. of rack end (1.5 mm (0.059 in.) horizon-
tal movement) = 12 deg. of steering angle
(f) Tighten the RH and LH lock nuts.
Torque: 55 N´m (560 kgf´cm, 41 ft´lbf)
NOTICE:
Make sure that the difference in length between RH and LH
tie rod ends and rack end screws are within 1.5 mm (0.059
in.).
(g) Install the RH and LH boot clips.
