Checking and Adding Power Steering Fluid
- Verify the vehicle is on a level surface.
- Inspect the fluid level in the reservoir.
- If the temperature of the fluid is below 75° C (167° F), verify the fluid is above the COLD MIN mark (3).
- With the engine idling at 1,000 RPM or less, turn the steering wheel from stop to stop several times in order to increase the temperature of the fluid to 80° C (176° F).
- Turn the engine OFF.
- Verify the fluid level is between the HOT MIN mark (6) and the HOT MAX mark (1).
- Adjust the fluid level if necessary. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication.
- When checking the fluid level after servicing the power steering system, bleed the air from the power steering system. Refer to Bleeding the Power Steering System .
NOTE:
Do not hold the steering wheel in the full turn position longer than 5 seconds, as damage to the steering pump may result.
NOTE:
Refer to Using Proper Power Steering Fluid Notice
in Cautions and Notices.
IMPORTANT:
Use new GM Goodwrench Automatic Transmission Fluid DEXRON®-III, GM P/N 12378470 (Canadian P/N 10952622), or the equivalent fluid.
