Checking and Adding Power Steering Fluid

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. The fluid level indicator is located on the fluid reservoir capstick. Inspect the fluid level when the engine compartment is cool. The fluid level should be at the FULL COLD mark.

When the engine compartment is hot, the fluid level should be at the HOT mark.

Loosening or removing the capstick when the engine compartment is hot relieves pressure in the power steering system. Pressure contributes to a quiet system.
