I wouldn't remove the pump from the car just yet - they can make groaning sounds when the fluid and filter is too dirty.

The fluid should be clean - the book says to use Dexron II

To drain the fluid see here =>

Then change the filter in the power steering pump - make sure you put the clip for the spring back in the same position.

Refill the pump with the correct fluid - jack the car off the front wheels and turn the steering wheel from lock to lock with the engine off - the fluid level should need to be refilled.

Once you have safely filled the system then you can start the engine and see if the level needs to be adjusted again.

(Many people describe filling the system with the engine running - seems like a stressful experience to me as the fluid level will drop quickly potentially running the pump dry which isn't a good thing)

If the fluid turns dirty again you ought to repeat the drain and fill procedure until it stays clean.
