  1. Park the car on a level surface.

It is recommended that the power steering fluid be checked when hot. However, the power steering fluid dipstick also has marks for checking the fluid when cold.

  1. Start the engine and turn the steering wheel all the way to the left and right several times. This will raise the fluid temperature to approximately 122-176 degrees F (50-80 degrees C).
  3. With the engine idling, check the level of fluid in the power steering pump-s reservoir. The fluid should be maintained at the MAX line with the engine idling and at the MIN line with the engine off.
  5. If still idling, turn the engine off. If the system requires fluid, clean around the reservoir cap with a shop rag to prevent contaminating the fluid with dirt.
  7. Remove the cap and add the required amount of fluid to the system.
  9. Install the reservoir cap.
