What brand Power Steering Fluid for my 2003 Chevy?

I tried several Power Steering Fluids and ATF's in 2000 MB E430, none works as good as Valvoline Maxlife PSF. All but Maxlife PSF made my steering whine when turning. Valvoline Maxlife PSF costs is very reasonable too, only $4.xx/qt.
Did you happen to try the Honda fluid? I understand it has more additives than regular PSF.
I use nothing but Valvoline maxlife PSF in all my GMs and with good results. Cheap about 4.80 a qt.
If it has the variable assist or magnasteer you should use the fluid spec. recommended in the manual. I got negative response for putting ATF in there. It is widely availiable.
I am sure the pump will operate trouble free with ATF. I have been made aware that the valving set up on the rack can be fouled & seals could be compromised. It was never really clear the feedback I was given. I spent far to much time searching this out. But there was enough for me to just go buy the gallon of spec fluid and be done with any debates on the subject. The fluid turned black and I felt a need to flush it out and I used ATF. It was very clean when I replaced it with O'reilly PS which is GM specified. It was difficult getting feedback that changed my mind about the ATF. That and the fact that a rack costs $400+ for just the part. Who wants to change a rack? The labor could make it a $800 dollar bill.
i'm also running MaxLife PS for the high miles
I've always used GM Vehicle Care OEM PSF. Cost around $8-9/quart at your local GM/Chevy shop.
You probably could get away with a number of different brands that are cheaper, but a few quarts goes a long way so I don't see the cost as a big deal.

I use Amsoil synthetic PSF in my '04 Silverado and it works great, especially in the sub zero winter conditions.
The part # in my owners manual is 1052884. Has this been superceded?

Yes, Maxlife PSF has stop leak.

I found 9985010 at the auto parts store. Will this work? Haven't had time to hit the dealer.
Considering your location, I'll bet the dealer has GM "Cold Weather" power steering fluid, which is a semi-synthetic of some kind. It's green rather than amber. It worked well in my 2001 Silverado with rack & pinion through three Michigan winters .
