STEERING -On-vehicle Service37A-9
POWER STEERING FLUID LEVEL CHECK
1. Park the vehicle on a flat, level surface, start the engine,
and then turn the steering wheel several times to raise
the temperature of the fluid to approximately 50 - 60_C.
2. With the engine running, turn the wheel all the way to
the left and right several times.
3. 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.
POWER STEERING FLUID REPLACEMENT
1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the
oil into a container.
4. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
5. While operating the starting motor intermittently, turn the
steering wheel all the way to the left and right several
times to drain all of the fluid.
6. Connect the return hoses securely, and then secure it
with the clip.
7. Fill the oil reservoir with specified fluid up to the lower
position of the filter, and then bleed air.
Specified fluid:
Automatic transmission fluid DEXRONII
Caution
Do not use ATF-SPIIM and ATF-SPIII.
POWER STEERING SYSTEM BLEEDING
1. Jack up the vehicle and support the front wheels with
rigid racks.
2. Disconnect the ignition coil connectors. (Refer to
GROUP16 - Ignition System.)
3. Cranking the engine with the starter several times
intermittently (during 15 to 20 seconds), turn the steering
wheel left and right fully five or six times.
Caution
(1) During the bleeding, refill the fluid so that the
level never falls below the lower position of the
filter.
(2) Be sure to bleed air only while cranking. If the
bleeding is done with the engine running, the air
will be broken up and absorbed into the fluid.
4. Connect the ignition coil connectors and idle the engine.
5. Turn the steering wheel left and right fully until no bubbles
comes out in the oil reservoir.
6. See that the fluid is not milky and that the fluid level
is up to the specified position on the level gauge.
7. See that the fluid level changes little when the steering
wheel is turned left and right.
8. Check difference in fluid levels between the engine
stopped and running.
Fluid level change: Within 5 mm

STEERING - Power Steering Gear Box and Linkage37A-16
POWER STEERING GEAR BOX AND LINKAGE
REMOVAL AND INSTALLATION
Caution: SRS
Before removing steering gear box, refer to GROUP 52B. Also, put the front wheels in straight-ahead
position. Failure to do so may damage the SRS clock spring and render the SRS air bag inoperative,
which results serious driver injury.
Caution
If the vehicle is equipped with the Brembo disc brake, during maintenance, take care not to contact
the parts or tools to the caliper because the paint of caliper will be scratched. And if there is
brake fluid on the caliper, wipe out quickly.

REFRIGERANT LEVEL TEST THROUGH
PERFORMANCE TEST
1. Start the engine.
2. Turn on the A/C switch, and set the A/C control to MAX.
COOL.
3. Adjust the engine speed to 1,500 r/min.
4. Check the refrigerant level (bubble state) through the
sight glass.
ItemState
Insufficient refriger-
antMany bubbles are seen. If refrigerant
is extremely low, it appears white.
Sufficient or excess
refrigerantNo bubbles are seen
NOTE
1. If insufficient, replenish the refrigerant as follows.
a) Replenish until bubbles disappear from the sight
glass.
b) After the bubbles disappear from the sight glass,
replenish 100g of refrigerant.
2. If excessive, replenish the refrigerant as follows.
a) Drain the refrigerant until bubbles can be seen
through the sight glass.
b) Replenish until bubbles disappear from the sight
glass.
c) After the bubbles disappear from the sight glass,
replenish 100g of refrigerant.
MAGNETIC CLUTCH TEST
1. Disconnect the connector to the magnetic clutch.
2. Connect battery (+) voltage directly to the connector for
the magnetic clutch.
3. If the magnetic clutch is normal, there will be ”click”. If
the pulley and armature do not make contact (’click’),
there is a malfunction.
RECEIVER DRIER TEST
Operate the unit and check the piping temperature by touching
the receiver drier outlet and inlet.
If there is a difference in the temperatures, the receiver drier
is restricted.
Replace the receiver drier.
