power steering fluid temp?

Does anyone have any idea what temperature full hydro steering systems run at? I know the hotter the fluid the easier it cavitates, so cooler is better, but I have also heard too cold is bad as well...

What temperatures are you guys seeing, and what temps do you shoot for?

ha I just asked the same question without seeing your post... I installed a oil temp gauge and put the sender right into my ext reservoir. I saw temps no higher than mid 150ish this past weekend... that was a couple hour trail ride and it was 90ish outside.

DR, are you running a cooler?

I'm getting ready to plumb up my hydro system and debating if I really need a cooler or not.

I would think whether the systems have coolers or not would have a big effect on what the temps are.

I was thinking of adding an A/C condensor to my hydro steering setup. not only to cool it, but to also add more capacity. my truck drives fine when I first start it up and the fluid is cold. so I dont see how being "too cold" would make a difference.

IIRC 80ish is minimum recomended, but I'm not real sure. I looked into this a little when hydro assist first hit the desert car scene and I was switching all our cars over. But that was a looooong time ago.

Minimum temp is no problem, it will get warmed up enough quick.
Keeping it cool is the hard part.
FWIW... I think 280 is really getting warm, 300+ is time to let-er cool off.

no cooler installed right now... I had one but I put a hole in it. I expected to see soaring temps now that I got that gauge installed... but it NEVER went over 165* I run GM power steering fluid.
