Power Steering Hydraulic System Bleeding
NOTE:
If air was introduced into power steering hydraulic system during servicing, bleed system. Aerated fluid, which appears Light Tan in color, results in poor steering performance and will cause pump damage.
- Turn ignition off. Raise and support front of vehicle with wheels off of ground. Turn wheels fully to left. Add fluid to bring level to FULL COLD mark on dipstick. DO NOT install reservoir cap. Turn wheels from left stop to right stop at least 20 times while an assistant monitors fluid level (add fluid as necessary to maintain level at FULL COLD mark). Ensure engine remains off.
- If reservoir overflows while turning wheel, air is trapped in system; check for leaks such as loose connections. If reservoir does not overflow, start engine. With engine idling, add fluid to bring level to FULL COLD mark. Install reservoir cap. Return wheels to center position.
- Lower vehicle. Continue to run engine for 2 minutes. Turn wheels from left stop to right stop. Check for leaks. Ensure fluid level is at FULL HOT mark when fluid is stabilized at operating temperature. Also, check for smooth power assist, noiseless operation and proper fluid condition (i.e. no bubbles, no foam, no discoloration).
