Turn the key off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Remove the cap again and look at the fluid level on the dipstick The fluid level should be between the ADD and HOT marks when the engine is cold. 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. When the engine compartment is hot, the level should be at the HOT mark. If the fluid is at the ADD mark when the engine is cold or hot, power steering fluid should be added.
