Changing your power steering fluid needs to be done. To replenish additives. There are many additives that are in power steering fluids. Most owners never think of changing the PS system. Or even know about the PS filter that can be cleaned. I know that there's a thought that Automatic trans fluid ( ATF ) can be used in the PS system. In a pinch. Yes. But will need to be changed ASAP. ATF lacks one very important additive. An anti foaming agent. If you had only ATF in your PS system. You'll get the pretties pink foam come out of the PS pump to clean up. It's not hard to change the PS fluid. There's a standard hose clamp on the low pressure hose on the back of the PS pump. Loosen that clamp. then pull the hose off. This will drain the PS pump. Then remove the PS filter. This will allow more fluid to drain out. Then put the low pressure hose back on the PS pump. And secure the hose clamp. Refill the pump. And start the engine. Then turn the steering wheel full left, then right. Then run your windshield wipers. This process WILL NOT change all the PS fluid. I would suggest that after you run the system. Change the PS fluid again. Bob Dunahugh
