Gm Power Steering Fluid

[Charmet37]

Hey guy’s, Anyone know what power steering fluid is Gm part # 89021186….Could it be Prestone psf or transmission fluid?

Are you asking for a suitable substitute?

Just use dex III from a reputable brand.

Yes, A substitute or anything that’s works.

Prestone yellow bottle. I use it in my Chevy truck and it can be found most anywhere.

I would go off color. Red=top off with Dex 3, Clear(ish)= top off with psf

Real AC Delco PSF is clearish for whatever reason. I believe that so is Prestone PSF. I got 200,000 miles on my original 2008 Suburban power steering pump using AC Delco PSF before the pump started to leak during winter weather. The steering gear and hydro boost are still in good shape. I changed out the pump and used AC Delco, however, I’m thinking of using Prestone next time I change fluid for whatever reason. I believe the AC Delco stuff is over $10 per quart but hey, it’s not like you change it every 6 months. For me it’s once every 5 years.
Here is some info on on Prestone.

NAPA has power steering fluid that is supposed to meet the GM requirements: https://www.napaonline.com/en/p/PSF9832?impressionRank=3

A lot of store brands (like O'Reilly's house brand Master-something-or-other) have the GM spec on the bottle. I believe most PSFs are universally compatible with that spec.

I've used Prestone in GM vehicles for a very long time (including my 20 year old truck) without any problems.

GM recommended Dex VI for cold operations. I no longer blow out power steering hoses in the cold.

Can you elaborate? Which GM models does this apply to? Thanks.

That part number was superseded by 10-5073. My car also specified 89021184 too, but I had no problem with 10-5073.

I also tried Valvoline power steering fluid for my car. Both fluids have the same thickness, but the fluids smelled differently. I decided to use the AC Delco brand since I didn't want the universal additive packs affecting my car.

How would the universal DI package affect your power steering system?

What if it's black with white chunks floating on top?

There's a TSB for certain GM models to run Pentosin CHF202 when used in extremely cold environments. This also supersedes the old TSB of using Dexron ATF.

Then he needs a full fluid change and to go with the fluid of his choice.
