Power Steering Fluid: Service and Repair
1. Raise and support the front end of the vehicle off the ground until the wheels are free to turn.
2. Remove the fluid return line at the pump inlet connector and plug the connector port on the pump. Position the line toward a large container to
catch the draining fluid.
3. While running the engine at idle, fill the reservoir with new power steering fluid. Turn the steering wheel in both directions. Do not contact or hold
the steering wheel to the wheel stops. This will cause the pump to go to pressure relief mode, which may cause a sudden fluid overflow at the
reservoir.
4. Install all the lines and hoses. Fill the system with new power steering fluid and bleed the system as described in Bleeding The Power Steering
System. Operate the engine for about 15 minutes.
Remove the pump return line at the pump inlet and plug the connection on the pump. While refilling the reservoir, check the draining fluid for
contamination. If foreign material is still evident, replace all lines, disassemble and clean or replace the power steering system components. Do not
re-use any drained power steering fluid.
