Hey everyone!
I've got Jimmy power steer and a Jimmy auto radiator in my sierra and I was wondering if it was a good idea to run the return line from the box through the radiator then to the Res. Better than nothing? Thoughts?

I'm no expert.
From my dumbo thinking,
it could be putting heat into the ps fluid most of the time.
Only cooling it, if ps fluid is hotter than engine temperature.?

But sounds like it could be ok,
just depends what the various operating temps are.

In my Vitara, I stopped using the radiator auto cooler,
and used a separate one, because motor was warming auto fluid,
rather than cooling it, under some conditions.

Hmm that sounds logical. Thanks for the input!

Yeah it won't be advantageous to run power steer fluid through the radiator as it usually doesn't get anywhere near as hot as transmission fluid.

ah ok, thanks for that. Explains why I couldnt find any info on it.
