I am using one of those from a 79 bronco now with the leaky add on cooler. I just thought i never wanted to just use the power steering cooler by itself, but it may be enough.
There's also the tradition of buying when it's more practical. I'm sure "back in the day", guys bought stuff. Otherwise there wouldn't be any after market businesses. Just a thought. Also, from the pics I've seen, some of that "I did it myself" stuff looked and worked like shit.
All taken care of , after checking with a buddy of mine he sold me a "B&M -70268" cooler that sells for about $65.00 + or - , for $20.00. It's used but in good condition. 11"x7"x 3/4" ,rated at 13,000 BTU , should do the job along with the other smaller one that's in line with it. Got it on and took it for a drive, no leaks. Thanks for the help to all.
I ran the condenser out of a Pepsi machine as a trans cooler on my 48 when I had a turbo 400 in it The thing is, aftermarket trans coolers aren't real expensive and they are even pretty easy to find used and cheap in the pick a part yards.
The idea isn't as crazy as it seems. Large trucks typically have turbo intercooler(gets very hot under high boost), AC condenser(can get hot enough to burn skin), power steering cooler, and sometimes other misc coolers, all in front of the engine's radiator!
my experience with coolers and temp gauges has been; the little power steering cooler in a 2200# roadster....................180 deg B&M small plate fin cooler.......180 deg Factory GM truck cooler.........180 deg 5/16 brake line back into trans.180 deg I have stopped worrying about the trans cooler unless I am pulling or racing with a stall converter.
