If you want to flush it, cut a short piece of 3/8 hose and plug it, then attach it to the return inlet of the p/s pump. the hose that normally goes there then goes into a catch can. start the engine, turn the steering wheel back and forth, when the oil going into the can is clean you have a flushed system it may take a quart to do it.
have fun
