GENERAL PROCEDURES
Start the engine and slowly turn the steering
wheel from lock to lock and add power
steering fluid until the power steering fluid
in the power steering fluid reservoir does
not drop.
8. Switch OFF the engine and examine the
power steering hose connections, steering
gear boots, power steering valve body and
power steering pump for external leaks.
9. Check the power steering fluid level. Fill the
power steering fluid reservoir to the MAX
mark with the appropriate power steering
fluid.
For additional information, refer to:
Specifications (211
-00 Steering System -
General Information, Specifications).
10.
N0TE:When bleeding the power steering
system the vacuum will decrease. Using
the special tools, maintain a sufficient
vacuum of
38cm-Hg. If the vacuum
decreases by more than
5cm-Hg in 5
minutes, the system should be checked for
leaks.
Using the special tools, bleed the power
steering system in the following sequence.
1. Start the engine and slowly turn the steering
wheel from lock to lock once; then turn the
steering wheel to the right, just off the stop.
2. Switch OFF the engine.
3. Using the special tools, create a vacuum of
38cm-Hg. Maintain the vacuum until the air
is evacuated from the system (minimum of
five minutes).
4. Release the vacuum.
5. Repeat the power steering bleeding
procedure, turning the steering wheel to the
left, just off the stop.
11. Remove the special tools. Fill the power
steering fluid reservoir to the MAX mark
.
with the appropriate power steering fluid (
as necessary.
For additional information, refer to:
Specifications (211
-00 Steering System -

12. Start the engine, turn the steering wheel
from lock to lock. If excessive noise is
apparent, repeat the power steering
bleeding procedure.
13. Lower the vehicle.
14.
If the noise level is still unacceptable, leave
the vehicle standing overnight then repeat
the power steering system bleeding
procedure.
