Power Steering Bleeding: Service and Repair
Bleed air from the system after replacing the fluid or servicing the power steering hydraulic system. Air in the system prevents an accurate fluid level
reading, causes pump cavitation noise, and over time, could damage the pump. To bleed the power steering system, proceed as follows:
Important: When adding fluid or making a complete fluid change, always use GM P/N 1050017 (or equivalent meeting GM Spec. No. 9985010)
power steering fluid. Failure To use the proper fluid will cause hose and seal damage and fluid leaks.
1. With the engine off and front wheels lifted off the ground and turned all the way to the left, add either standard power steering fluid or optional
cold climate fluid to the "Full Cold" mark on the fluid level indicator.
Important: This may require turning the wheels from side to side several times. Keep the fluid level at the "Full Cold" mark. Fluid with air in it
has a tan appearance. This air must be eliminated before normal steering action can be obtained.
2. Bleed the system by turning the wheels from side to side without hitting the stops.
3. Start the engine. With the engine idling, recheck the fluid level. If necessary, add fluid to bring the level to the "Full Cold" mark.
4. Return the wheels to the center position. Lower front wheels to ground. Continue running the engine for two or three minutes.
