Hydraulic System Bleeding

NOTE: If air was introduced into hydraulic system during servicing, bleed hydraulic system. Aerated fluid may result in poor steering performance and cause damage to power steering pump.
  1. Turn ignition off. Raise and support vehicle with front wheels off ground. Turn wheels fully to the left. Add power steering fluid to FULL COLD mark on dipstick. Turn wheels from side to side several times. Add power steering fluid as necessary to maintain fluid level at FULL COLD mark.
  2. Start engine. With engine idling, add power steering fluid as necessary to bring level to FULL COLD mark. Return wheels to center position. Lower vehicle. Continue to run engine for 2 minutes to eliminate trapped air and raise fluid to operating temperature. Turn wheels in both directions and check for smooth operation and proper fluid level.
  3. Road test vehicle. Check for leaks. Ensure fluid level is at FULL HOT mark when fluid is stabilized at normal operating temperature.
