The power steering fluid replacement procedure includes
the following two stages:
• | Flushing the old fluid from the system with new fluid. |
• | Bleeding the system in order to remove any trapped air. |
- Raise the front of the vehicle off of the ground. Ensure that
the front wheels are free to turn. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Remove the fluid return line at the pump reservoir inlet connector.
- Plug the inlet connector port on the pump reservoir.
- Position the power steering fluid return line toward a large container
in order to contain the draining fluid.
- Start the engine.
- Run the engine at idle.
- Have an assistant simultaneously fill the reservoir with either
of the following fluids:
7.1. | A standard power steering fluid: |
• | 0.47 L (16 oz) of GM P/N 1052884 |
• | 0.95 L (32 oz) of GM P/N 1050017 |
7.2. | A cold climate power steering fluid: |
• | 0.47 L (16 oz) of GM P/N 12345866 |
• | 0.95 L (32 oz) of GM P/N 12345867 |
Notice: Do not hold the steering wheel against the stops while flushing the
power steering system. Holding the steering wheel against the wheel stops
will cause high system pressure, overheating, and damage to the power steering
pump and/or gear.
- Turn the steering wheel from stop-to-stop.
Ensure that all of the old power steering fluid is cleared from the
power steering system.
- Add approximately 0.95 L (1 qt) of fluid in order
to flush the power steering system.
- Unplug the pump reservoir inlet.
- Reconnect the return line.
- Turn the ignition switch to the OFF position.
- Fill the reservoir to the FULL COLD mark. Refer to
Refilling the Power Steering System
- Bleed the power steering system. Refer to
Power Steering System Bleeding
