I run a power steering cooler on my Barracuda. I run the lines under the battery tray and mounted the cooler on the AC condenser. I was trying to "hide" the lines the best I could. I also hid the Magnefine filter under the battery tray.

The PS oil cooler I selected was the cheap Hayden unit.

I just installed the Derale 13200 Power Steering Cooler Kit on my Jeep Cherokee. I like that unit better because that unit has pieces of plastic protecting the fins. This made it easier to wiggle on the hoses without mangling the fins. It is not much more money than the Hayden unit.

The PS oil temperature is about 40-50 degrees cooler with the cooler. Prior to installing the cooler, I would routinely see 230+ oil temps using a laser temp sensor on the oil in the PS pump reservoir.
