BLEEDING THE POWER
STEERING SYSTEM
1. Disconnect the fuel line. Using a starter motor,
crank the engine and turn the steering wheel from
lock to start 5 or 6 times.
Notice: Do bleeding with engine cranking. If bleed
with idling, there can be a air contact with oil.
2. Connect the fuel feed line and start the engine at
idle speed.
3. Turn the steering wheel from lock to lock until there
is no more air in oil reservoir.
4. Connect the oil level is within specification.
5. By turning the steering wheel left to right, check
the oil level change.
Notice: If oil is not changes more than 5 mm, do
bleeding again. If oil level rises suddenly when
stopped engine, again.
MAINTENANCE
CHECKING AND ADDING FLUID
Notice: When adding fluid or making a complete fluid
change, always use DEXRON. - II power steering fluid.
Failure to use the proper fluid will cause hose and seal
damage and fluid leaks.
1. The power steering fluid level is indicated by marks
on a fluid level indicator on the fluid reservoir cap.
2. If the fluid is warmed up to 66 °C (150 °F), the fluid
level should be between the MAX and MIN marks.
Add fluid as needed.
3. If the fluid is cool, 21 °C (70 °F), the fluid level should
be at the MIN mark. Add fluid as needed.

POWER STEERING RACK AND
PINION GEAR BENCH TESTING
Removal and Installation Procedure
Notice: Pressure checks or pressure and flow checks
may also be conducted using this setup.
1. Disconnect and remove the power steering gear.
Refer to “Rack and Pinion Assembly” in this
section.
2. Place the power steering gear on a bench next to
the vehicle.
3. Disconnect the pressure line at the point where the
hose connects to the pipe. Extend this line to reach
the power steering gear on the bench.
4. Disconnect the return line from the power steering
fluid reservoir. Extend this line to reach the power
steering gear on the bench.
5. Connect the power steering pipes to the power
steering gear.
6. Start the engine and allow it to idle for 10 seconds.
7. Check the power steering fluid level. Refer to
Section 6A, Power Steering System.
8. Start the engine and turn the rack and pinion stub
shaft a full turn in each direction. Hold the shaft
against each stop for 5 seconds.
9. Inspect for possible leak points. Refer to Section
6A, Power Steering System.
Installation Procedure
1. Stop the engine.
2. Disconnect the power steering pipes from the power
steering gear.

3. Remove the extensions and reconnect the pressure
and return lines.
4. Install and connect the power steering gear. Refer
to “Rack and Pinion Assembly” in this section.
5. Start the engine and allow it to idle for 10 seconds.
6. Check the power steering fluid level. Refer to
Section 6A, Power Steering System.
STRAIGHT-AHEAD CHECK
After all the necessary operations on the steering gear
are completed (removing and installing, disassembling
and assembling), check the exact straight-ahead posi-
tion of the steering in each case.
With the vehicle on the floor, place the steering wheel
in the straight-ahead position. Mark the centerline of
both tires on the floor. Turn the steering wheel all the
way to the right and mark the new centerline of both
tires on the floor.
