I do not see why it wouldnt cool the fluid. Although I have never heard of it being done...... but someone has to be first.

radiator-power steering?
Hello I just got done rebuilding a 410 for my 70 F-250 4x4 and had to buy a new radiator for it. But my truck has a 4spd so I don't need the cooler. I was wondering if anyone has hooked up thier power steering return line to the cooler in the radiator? Would it work? I thoutgh the temps might be to close or the radiator might be hotter than the power steering fluid which would make it pointless. The reason I ask is that the drive from where I work to where I live is all uphill and by the time I get home the pump is whining. Yes I have checked the fluid. Thanks for your help and input. comertrucks

Thanks. But I still need to know about the temp differeces. Will there be enough difference for it to have a coolng effecct on the power steering fluid? Thanks again for the help.

i have a 69 f-250 4x4 pickup that i put a 78-79 power steering box into. i have a radiator out of a truck that used to have an automatic. i ran the return line through the tranny cooler and haven't had any problems at all. this keeps the fluid at a more constant temp and everything works great.

Thanks. I knew someone out there had thought of using it to cool the power steering fluid too. I was driving around tonight on some dirt roads and I think it got hot, the pump was whining like the fluid had air in it. I will try it as soon as i get my carb dailed in. Thanks again.

This is probably a real good idea. I know that the power steering fluid can get too hot. I have never seen any specs on how hot. My f-250 has the little cooler on the return line. Don't remember seeing this on cars.

You guys are thinking in the right direction, but instead of using the rad trans cooler, it would be best to use a small trans cooler mounted in front of the radiator. This way, you are cooling the fluid down even more so than the temp it would reach in the rad.
