70 Dart, power steering
Even after I raised my 360 magnum engine to clear the ps box, the couple and the box are still too close to the header tube
Im not interested in wrapping the box with heat shield
I thought, why not run it thru the trans cooler, a new large ac condersor.
I figured that would work but the only way it would work is if i teed in to the trans line and installed a small valve to adjust the amount pumping thru the ps reservoiir.
After experimentation the reservoir level would remain at the proper level. .
What do you think ?

I got a power steering fluid cooler off a Dodge Ram at the pull a part. Plumbed it in line with the power steering return line on my 83 D150.

I would still need a valve , otherwise the reservoir would overflow. Remember the ps
Is a "closed " system, using a set amount of fluid
 
I added a plate style cooler to the power steering after I added Hydroboost brakes. This is on my ‘74 Dodge Truck. Tee into the return line.

IMHO, you could just run the return line through the cooler,. No tee, no valving. The return line is not under pressure and it is always circulating

A simple piece of sheet metal bent to the basic shape of the gear will deflect a lot of radiant heat.

I don't think you're hearing what he is saying.

He's saying to run a completely separate cooler for the P/S. It's much simpler, it works, and Ma Mopar did this very thing on a lot of vehicles and in particular on police service vehicles. You can probably still find the factory setup in many junkyards.

If you were to add a cooler to the return line, it would just increase the “set amount” of fluid. Just like an oil cooler for an engine...
