GM Prizm/Nova 1985-1993 Repair Guide

Power Steering Pump



The correct fluid for the power steering system is Dexron® II automatic transmission fluid. There are no acceptable substitutes; any other fluid may damage the system.


See Figures 1 and 2

The fluid level in the power steering reservoir should be checked at least every 5,000 miles. The vehicle should be parked on level ground, with the engine warm and running at normal idle. Remove the filler cap and check the level on the dipsticks; it should be within the HOT area on the dipstick. If the level is low, add Dexron® II ATF until the proper level is achieved.

Look down in the reservoir and check for evidence of foaming or which indicates the existence of air in the system. The power steering system does not consume fluid in normal use; any sign of fluid loss or air in the system should be treated as a potential problem.

The power steering fluid does not require replacement during the normal life of the car.
