The power steering pump uses Dexron®II automatic transmission fluid.
It is a good idea to perform the power steering fluid level check at the same time as all the other fluid levels.
To check the fluid level, first park the car on a level surface. Start the engine and turn the steering several times to raise the temperature of the fluid. With the engine idling, turn the wheel all the way to the left and right several times. Turn the engine off and remove the dipstick from the reservoir. The level should be between the "MIN" and "MAX" marks on the dipstick. If the level is not as specified, add fluid as necessary. Stop the engine and compare the levels in the power steering pump reservoir with and without the engine running. If the level varies 5mm (0.2 in) or more, there is air in the system. If the fluid level rises suddenly after stopping the engine, this is also an indication that air is trapped in the system.
If checking the level in extremely cold weather, a grinding noise may be heard from the power steering pump as soon as the engine is started and you begin to turn the steering wheel. This is not abnormal and is due to the flow characteristics of the power steering fluid in cold temperatures.
