When adding fluid or making a complete fluid change, always use GM P/N 1050017, 1052884, power steering fluid or equivalent. DO NOT use automatic transmission fluid. Failure to use the proper fluid may cause hose and seal damage and fluid leaks.
For colder climates, another type of power steering fluid, available through GM dealerships, is available. However, the system must be flushed and bled before using the cold climate power steering fluid.
See Figures 1 through 5
The power steering fluid level should be checked at every oil change. The power steering pump and reservoir are integrated into one unit bolted to the front of the engine.
The power steering fluid reservoir is directly above the steering pump. The pump is located on top of the engine on the right (passenger's) side.
Power steering fluid level is indicated either by marks on a see through reservoir or by marks on a fluid level indicator in the reservoir cap.
If the fluid is warmed up (about 150°F/66°C), the level should be between the HOT and COLD marks or at the HOT mark.
If the fluid is cooler than 150°F (66°C), the level should be between the ADD and COLD marks.
