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.
See Figures 1, 2 and 3
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 150ºF/66ºC), the level should be between the HOT and COLD marks.
If the fluid is cooler than 150ºF (66ºC), the level should be between the ADD and COLD marks.
