Vehicle Care 10-23 Power Steering Fluid How to Check Power Steering Fluid Check the level after the vehicle has been driven for at least 20 minutes so the fluid is warm. To check the power steering fluid: 1. Turn the ignition to LOCK/OFF and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and pull it straight up. 4. Wipe the dipstick with a clean rag. 5. Replace the cap and completely tighten it. 6. Remove the cap again and look at the fluid level on the dipstick. When the engine is hot, the level should be at the hot MAX level. When the engine is cold, the fluid level should be between MIN and MAX on the dipstick. See Engine Compartment Overview on page 10‑6 for information on the location of the power steering fluid reservoir. When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless a leak is suspected in the system or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 11‑7. Always use the proper fluid.
