Power Steering System Bleeding

NOTE: Power steering system bleeding must be used when power steering pump is removed or replaced. This ensures power steering side of power steering pump is properly bled.
  1. With engine off, check fluid level in power steering pump reservoir, located near passenger's side strut tower. If system is hot, ensure fluid level is at HOT line on reservoir. If system is cold, ensure fluid level is at COLD line on reservoir. Add Dexron-II ATF until proper fluid level is obtained.
  2. Start engine. With engine RPM less than 1000 RPM, turn steering wheel to right as far as possible and hold in this position for 2-3 seconds. Turn steering wheel to left as far as possible and hold in this position for 2-3 seconds.

  4. Subtract measurement with engine running from measurement with engine stopped. Difference in fluid level should be no more than .20" (5.0 mm).
  5. If difference in fluid level exceeds .20" (5.0 mm.), add Dexron-II ATF until proper fluid level is obtained. Shut engine off.
