Flushing Power Steering System

WARNING: This page is about a different car, the 2013 RAM 3500 HD and 2013 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

Flushing is required when the power steering/hydraulic booster system fluid has become contaminated. Contaminated fluid in the steering/booster system can cause seal deterioration and affect steering gear/booster spool valve operation.

NOTE:

The engine should not be run so that all of the fluid is drained from the system. The pump should never be run without fluid.

Raise the front end of the vehicle off the ground until the wheels are free to turn.
Remove the return line from the pump.
Plug the return line port/ports at the pump.
Position the return line/lines into a large container to catch the fluid.
While an assistant is filling the pump reservoir start the engine.
With the engine running at idle turn the wheel back and forth.
NOTE:
Do not contact or hold the wheel against the steering stops.
Run a quart of fluid through the system then stop the engine and install the return line/lines.
Fill the system with fluid and perform Steering Pump Initial Operation. Refer to PUMP, STANDARD PROCEDURE .
Start the engine and run it for fifteen minutes then stop the engine.
Remove the return line/lines from the pump and plug the pump port/ports.
Pour fresh fluid into the reservoir and check the draining fluid for contamination. If the fluid is still contaminated, then flush the system again.
Install the return line/lines and perform Steering Pump Initial Operation. Refer to PUMP, STANDARD PROCEDURE .
