POWER STEERING SYSTEM AIR
BLEEDING
M1372002200330
Perform air bleeding procedure as necessary after
replacing the steering gear or the steering fluid lines.
1. Raise and support the front wheels.
2. Disconnect the ignition coil connectors (Refer to GROUP 16, Ignition Coil
P.16-38 or P.16-39).
CAUTION
Perform air bleeding only while cranking the
engine. If air bleeding is performed while the
engine is running, air could enter the fluid. Dur
-
ing air bleeding, refill the steering fluid supply so
that the level never falls below the "MIN" mark on
the oil reservoir.
3. Turn the steering wheel all the way to the left and
right five or six times wh ile using the starter motor
to crank the engine intermittently several times
(for 15 to 20 seconds).
4. Connect the ignition coil connectors (Refer to GROUP 16, Ignition Coil
P.16-38 or P.16-39).
5. Start the engine (idling).
6. Turn the steering wheel to the left and right until there are no air bubbles in the oil reservoir.
7. Confirm that the fluid is not milky, and that the level is between "MAX" and "MIN" marks.
8. Confirm that there is very little change in the fluid
level when the steering wheel is turned left and
right.
CAUTION
If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled. If
air bleeding is not complete, there will be abnor
-
mal noises from the pump and the flow-control
valve, and this condition could cause reduce the
life of the power steering components.
ACX01131With engine running With engine stoppedAC
Fluid level change: Within 5 mm
9. Confirm that the change in the fluid level is no more than 5 mm when the engine is stopped and
when it is running.
10.If the change of the fluid level is 5 mm or more,
the air has not been completely bled from the
system. The air bleeding procedure must be
repeated.

1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•Power steering oil pressure gauge (MB990662)
•Power steering oil pressure gauge adapter (pump
side) (MB991548)
•Power steering oil pressure gauge adapter (hose
side) (MB991549)
2. Bleed air, then turn the steering wheel several times while the vehicle is not moving so that the
temperature of the fluid rises to approximately 50
−
60
°C.
3. Start the engine and idle it at 750 ± 100 r/min.
CAUTION
The pressure gauge shut-off valve must not
remain closed for more than 10 seconds.
4. Fully close the shut-off valve of the pressure gauge and measure the oil pump relief pressure
to confirm that it is within the standard value
range. Open it again immediately after checking
the pressure.
Standard value: 8.8 − 9.5 MPa
5. If it is not within the standard value, replace the oil pump.
