Hydraulic System Bleeding

NOTE: If air was introduced into hydraulic system during servicing, bleed system. Aerated fluid, which appears Light Tan in color, results in poor steering performance and will cause pump damage. Replace aerated fluid.
  1. Turn ignition off. Raise and support vehicle with front wheels off ground. Turn wheels fully to left. Add power steering fluid to COLD mark on dipstick. Turn wheels from side to side several times, but DO NOT  touch steering stops. Add fluid as necessary to maintain level at FULL COLD mark.
  2. Start engine. With engine idling, add fluid as necessary to bring level to FULL COLD mark. Return wheels to center position. Lower vehicle. Continue to run engine for 2-3 minutes to eliminate trapped air and raise fluid to operating temperature.
  3. Road test vehicle. Check for leaks. Ensure fluid level is at FULL HOT mark when fluid is stabilized at operating temperature.
