Power Steering Bleeding: Service and Repair
After replacing the power steering fluid or servicing the power steering hydraulic system, you must bleed air from the system. Air in the system
prevents an accurate fluid level reading, causes pump cavitation noise and over time could damage the pump. To bleed the power steering system
proceed as follows:
1. Begin with the engine off, front wheels off the ground, and wheels turned all the way to the left.
2. Add either standard power steering fluid or optional cold climate fluid, to the FULL COLD mark on the fluid level indicator.
3. Bleed the system by turning the wheels from stop-to-stop, but without hitting the stops.
Important: This may require turning the wheels from side to side up to 40 times. Keep the power steering fluid level at the FULL COLD mark.
Power steering fluid with air in it has a light tan appearance. This air must be eliminated from the power steering fluid before normal steering
action can be obtained.
4. Start the engine. With the engine idling, recheck the power steering fluid level. If necessary, add power steering fluid to bring the level to the
FULL COLD mark.
5. Return the wheels to the center position. Lower front wheels to the ground. Continue running the engine for two or three minutes.
