For 1990-2009 cars

Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.

1. Keep the power steering system clean. Inspect the power steering pump fluid level at regular intervals. Add fluid when required. Use only DEXRON®-III Automatic Transmission Fluid, GM P/N 12346143, or equivalent. Refer to Fluid and Lubricant Recommendations in Maintenance and Lubrication.
2. If there is any dirt in the power steering system, flush the dirt from the system. Refer to Power Steering System Flushing . If the system is exceptionally dirty, disassemble the pump before further usage.
3. Inspect all of the tubes, the hoses (4,5), and the fittings for leakage at regular intervals. The fittings must be tight. Ensure the clips, the clamps, the supporting tubes, and the hoses are in place and properly secured.

• | Inspect the hoses with the wheels in the straight-ahead position. Turn the wheels fully to the left and the right while observing the movement of the hoses. Ensure the hoses do not contact any other parts of the vehicle. Hose contact with the other parts of the vehicle could cause noise, vibration, chafing or wear.

• | The power steering hoses and the pipes must not be twisted, kinked, or tightly bent. The hoses should have sufficient natural curvature in the routing in order to absorb the movement and the hose shortening during the vehicle operation.

4. Air in the system will cause spongy action and noisy operation. When a hose is disconnected or when fluid is lost for any reason, bleed the system after refilling. Refer to Power Steering System Bleeding .
5. Stop the engine and allow the fluid to cool before checking the fluid level.
6. Inspect the fluid level on the reservoir (6).
7. If the fluid does not reach the MIN mark (3), add DEXRON®-III Automatic Transmission Fluid, GM P/N 12346143, or equivalent, to the MAX mark (2).
8. When checking the fluid level after servicing the steering system, bleed the air from the system. Refer to Power Steering System Bleeding .
