Hydraulic System Bleeding

CAUTION: If air was introduced into hydraulic system during servicing, system must be bled. Aerated fluid, which appears Light Tan in color, results in poor steering performance and may cause pump damage.
  1. With engine off, support vehicle with wheels off ground and wheels turned fully to left. Add power steering fluid to COLD mark on dipstick.
  2. Turn wheels from side to side, without touching stops at either end. Add fluid as necessary to maintain at FULL COLD mark. It may be necessary to repeat this step several times.
  3. Start engine. With engine idling, recheck fluid level. Add fluid, if necessary, to bring level to FULL COLD mark. Return wheels to center position. Lower vehicle. Continue to run engine for 2 to 3 minutes.
  4. Road test vehicle. Check for leaks. Ensure fluid level is at FULL HOT mark when fluid is stabilized at operating temperature.
