Bleed the air from the system before operating the vehicle
whenever the following components are installed:
• | The power steering pump |
• | The power steering hose |
Air in the power steering fluid system may cause the following conditions:
• | Unsatisfactory operation |
Use only the specified power steering fluid whenever fluid is added
to the power steering system. Do not use automatic transmission fluid or any
other unapproved fluids. Refer to
Fluid and Lubricant Recommendations
in Maintenance and Lubrication.
Before bleeding the system, ensure that the following components are
closed tightly enough to prevent air or fluid leaks:
Have enough power steering fluid to maintain the fluid in the reservoir
at all times during the bleeding procedure.
This procedure is designed to minimize the chance of fluid aeration
or overflow during the bleeding process.
Important: Do not install the reservoir cap during the bleeding procedure. Air
may be trapped in the system. When the engine stops, power steering fluid
will be forced out through the breather hole in the cap.
- Raise the front end of the vehicle until the wheels can turn freely.
Support the vehicle with suitable safety stands. Refer to
Lifting and Jacking the Vehicle
in General Information.
Important: Removing the drag link at the pitman arm and turning the steering wheel
stop to stop may cause the following conditions:
• | Increased steering gear travel |
• | End limiter valve misadjustment |
• | End limiter valve damage |
- Replace the end limiters if any of the above conditions exist. Refer
to
End Limiters Replacement
.
- Fill the reservoir.
Ensure that the following conditions are met:
• | The glass sight is covered |
• | The fluid level is within 50 mm (2 in) of the top
of the reservoir |
- Leave the cap off.
Important: Do not turn the steering wheel before completing operationals steps
thru 10.
- Start the engine.
- Operate the vehicle for 10 seconds.
- Turn the ignition switch to the OFF position.
- Continuously fill the reservoir.
Ensure that the following conditions are met at all times:
• | The glass sight is covered |
• | The fluid level is within 50 mm (2 in) of the top
of the reservoir |
- Repeat the procedure until no more bubbles appear in the reservoir.
- Fill the reservoir in order to cover slight glass within 50 mm
(2 in) of the top of the reservoir.
- Start the engine.
- Operate the vehicle for 10 seconds while turning the steering
wheel completely to the right and to the left.
- Turn the ignition switch to the OFF position.
- Continuously fill the reservoir.
Ensure that the following conditions are met at all times:
• | The glass sight is covered |
• | The fluid level is within 50 mm (2 in) of the top
of the reservoir |
- Repeat the procedure until no more bubbles appear in the reservoir.
