- Check the fluid level in the power steering oil reservoir and add if necessary. Install the powertrain control module (PCM) fuse.
- Start the engine.
- With the engine running, turn the steering wheel (3600) from stop-to-stop twice. Turn the engine off.
- Depress the brake pedal (2455) several times to discharge the accumulator.
- Repeat Steps 5 and 6.
- If foaming occurs, stop the engine and allow the foam to dissipate.
- Repeat Steps 5 and 6 as required, until all the air is removed from the system (when the foaming stops).
NOTE:
The Hydro-Boost power brake booster (2B560) is generally self-bleeding, and the following procedure will normally bleed the air from the power brake booster. Normal operation of the vehicle will further remove any additional trapped air.
