STEERING WHEEL RETURN TO CENTRE
CHECK
M1372001800317
Conduct a road test:
1. Make both gradual and sudden turns and check
the steering wheel return.
2. At a vehicle speed of approximately 35 km/h, turn
the steering wheel 90°, hold a few seconds, then
release. If the steering wheel then returns 70° or
more, the return can be judged satisfactory.
NOTE: There will be a momentary feeling or
"heaviness" when the wheel is turned quickly, but
this is not abnormal (Oil pump discharge amount
is especially apt to be insufficient during idling).
DRIVE BELT TENSION CHECKM1372001900392
For vehicles with 1300 and 1600 engine, refer to
GROUP 11A, On-vehicle Service − Drive Belt
Tension Check P.11A-7.
For vehicles with 2000 engine, refer to GROUP 11C,
On-vehicle Service − Drive Belt Tension Check
P.11C-7.
FLUID LEVEL CHECKM1372002000284
1. Park the vehicle on a flat, level surface.
2. Start the engine, and then turn the steering wheel
several times to raise the temperature of the fluid
to approximately 50 − 60°C.
3. With the engine running, turn the wheel all the
way to the left and right several times.4. Check the fluid in the oil reservoir for foaming or
milkiness. Check the difference of the fluid level
when the engine is stopped, and while it is
running. If the change of the fluid level is 5 mm or
more, air bleeding should be done.
FLUID REPLACEMENTM1372002100333
1. Raise and support the front wheels.
2. Disconnect the return hose connection, and then
connect a vinyl hose to the return hose, and drain
the fluid into a container.
3. Disconnect the ignition coil connectors (Refer to
GROUP 16, Ignition Coil P.16-38or P.16-39).
4. While operating the starter motor intermittently,
turn the steering wheel all the way to the left and
right several times to drain all of the fluid.
5. Connect the return hose securely, and then
secure with the clip.
6. Fill the oil reservoir with specified fluid up to
between "MAX" and "MIN" marks, and then bleed
the air.
Specified fluid: ATF DEXRON III or DEXRON
II
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).

ON-VEHICLE SERVICE
POWER STEERING37-14
CAUTION
Perform air bleeding only while cranking the
engine. If air bleeding is performed while the
engine is running, air could enter the fluid.
During 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 while 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
abnormal noises from the pump and the
flow-control valve, and this condition could
cause reduce the life of the power steering
components.
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.
OIL PUMP PRESSURE TESTM1372002300315
1. Disconnect the pressure hose from the oil pump,
and then connect the following special tools.
•MB990662: Power Steering Oil Pressure Gauge
•MB991548: Power Steering Oil Pressure Gauge
Adapter (pump side)
•MB991549: Power Steering Oil Pressure Gauge
Adapter (hose side)
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 1000 ± 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.
6. Check whether or not the hydraulic pressure is
the standard value when no-load conditions are
created by fully opening the shut-off valve of the
pressure gauge.
Standard value: 0.2 − 0.7 MPa

To eliminate a seal malfunction at the valve
housing alignment surface, the upper surface of
the oil seal should project outward
approximately 1 mm from the housing edge
surface.
Using special tool torque tube bearing installer
(MB990941), press the oil seal into the valve
housing.
>>I<< END PLUG INSTALLATION
1. Apply specified sealant to the threaded part of the
end plug.

DISCHARGING SYSTEMM1552013000105
Use the refrigerant recovery unit to discharge
refrigerant gas from the system.
NOTE: Refer to the Refrigerant Recovery and
Recycling Unit instruction Manual for operation of the
unit.
REFILLING OF OIL IN THE A/C SYSTEMM1552020000033
Too little oil will provide inadequate compressor
lubrication and cause a compressor failure. Too
much oil will increase discharge air temperature.
When a compressor is installed at the factory, it
contains 140mL <1300, 1600> or 120 mL <2000> of
compressor oil. While the A/C system is in operation,
the oil is carried through the entire system by the
refrigerant. Some of this oil will be trapped and
retained in various parts of the system.
When the following system components are
changed, it is necessary to add oil to the system to
replace the oil being removed with the component.
Compressor oil: SUN PAG 56

Evaporator: 60 mL
Condenser: 15 mL
