any suggestions on what works? Thanks.
earls make soem nice coolers, they are just like setrabs. somewhere in the project update forum there is a picture of mine and my power steering setup and a list

CarlC used a tubular type with fins like the one DSE sells.
I installed a Summit 3/4" thick trans cooler on my wife's 73 Camaro steering, but haven't run it on a track yet.

I bought the DSE one, changed out the ends to -6AN's and put on. Haven't checked temps yet. I was reading 220* at the steering box inlet fitting before.

I'm using a small Fluidyne oil cooler

I talked to Lee Manufacturing on the phone a couple of years ago. His recomendation was for a round tube type cooler like the auto trans coolers. The Mocal/Fluidyne type work well but fail sooner on desert truck systems he builds, they'd probably last forever on a street car but he mention "toroidal vibrations" or something, anyway puslations from the pump vibrate the cooler and are harder on the plate type coolers.

I'm using one from the LS1 Fbods- I plumbed it into the upper radiator hose.
how does that work? curious how you plumb a power steering cooler into a radiator hose? Does the radiator fluid somehow cool it?

Guess so, my pull-out LS1 had one attached too in the upper radiator hose, looks to be a factory bit (pic):

Guess it cools it to roughly ~180ish or whatever temp the coolant is at?

may not be real helpful but i'm using one from a 73 galaxie 500. seems to work ok with my mild engine and stock power steering system

I read somewhere that the SS cooler you show was not good enough for autocross. A guy was complaining his PS overheated autocrossing his SS Camaro.
I believe the SS was the only Camaro to get this cooler.

I believe the SS was the only Camaro to get this cooler.
Trans-Ams too. Or at least the partial VIN on the block decodes to a Pontiac.

Anyone running a cooler with a Hydroboost setup and an old style Saginaw pump? If so, I'd like to see some pics :D. I'm looking for ideas.
I am, I have a remote P-pump, with a cooler and the hydroboost, and a remote resevoir, here is the thread

Could you plumb your powersteering into a transmission cooler in a radiator if you are running a manual tranny? I picked up a used be cool radiator that was for an automatic but I am running a manual transmission so I was wondering if this was possible. But I dont know what kind of psi is generated in power steering and automatic transmissions systems.
good question, I would think that would be fine, but not sure

also yody are those march brackets you are running? Do you have AC? If so which setup is it?

I would try the auto trans cooler in the radiator. I asked Lee about that and he didn't seem to like the idea but didn't have a reason other than those have the flat plate type cooler and was worried about the vibrations.
Here is our second gen ps cooler, an auto trans type.

I've been doing exactly that for the last 6000 miles or so. No problems yet.

I wouldn't feel confident with the power steering fluid running through the radiator's transmission cooler unless it was the return side. Automatic transmissions run up to 300 p.s.i., but power steering goes higher. I don't know what pressure the P/S systems run, but I think it is two to four times the A/T system. The P/S system uses hydraulic hoses and fittings, and hydraulic systems run 3000 p.s.i.
Aeroquip has special hose for P/S lines.
Again, if you run the cooler on the return side, which will not be as effective, you should be fine. The return handles very little pressure.
My .02!
power steering coolers are always plumbed through the return side
