Default Power steering fluid question...

I bought power steering fluid from the dealer yesterday but didn't notice until I got home that the GM part number doesn't match what my owner's manual says to use. Does it matter? Thanks.

I recently bought one quart and the parts guy was careful to point out to me that the part number was different but the cross-reference indicated the old #.

Here's what I did. Used my Mity-Vac pump and drew out about 8oz (that's about what the reservoir holds). Then poured in the identical amount back to cold fill line. I poured the old stuff in a plastic cup and filled another plastic cup to the same fill line...made it easier. I then drove for a couple days. Then repeated this process a 2nd time. And then a 3rd time. I still have enough fresh fluid to do it one more time, so after 4 reservoir flushes I "theoretically" should have mostly fresh fluid in there.

Now the truth. On the third cycle, the fluid was still pretty dark...not as bad as the first cycle but still darker than I would have expected after swapping in 3/4's of a quart of fresh fluid. I may end up buying another quart and keep repeating the process (much like the procedure with the clutch fluid) until I'm satisfied. Or I'll just say to hell with it and leave well enough alone.

I don't suppose you would be interested in using a large set of industrial line cutters and a roll of duct tape? Job would be a lot quicker; somewhat messier; with questionable results.

LOL

I'm just a little distrustful of the dealer.

Thanks for the replies.
