Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.

1. Raise and support the front of the vehicle off the ground until the front wheels are free to turn. Refer to Lifting and Jacking the Vehicle in General Information.
2. Siphon the fluid from the reservoir.
3. Disconnect the power steering gear outlet hose from the reservoir.
4. Plug the reservoir.
5. Position the power steering gear outlet hose toward a large container to catch the draining fluid.
6. Start and run the engine at an idle while an assistant fills the fluid reservoir with DEXRON® III automatic transmission fluid, GM P/N 12346143 or equivalent.
