Notice: When adding fluid or making a complete fluid change, always use a power steering fluid meeting GM Spec. No. 9985010 or equivalent. Fluid for cold climates is also available through GM Dealerships; refer to Specifications for further information. Failure to use the proper power steering fluid can cause power steering hose and seal damage, fluid leaks and pump failure.

The power steering fluid level is indicated by marks on a fluid level indicator on the fluid reservoir cap. If the fluid is warm, about 66°C (150°F) or hot to the touch -- the fluid level should be at the HOT mark. If the fluid is cool, about 21°C (70°F), the fluid level should be at the COLD mark.
