Thread: 34 going up on jack stands for a while

Hello Jack, I see you have a 350 but I thought you had a big block a while back? I still have a box in my garage with your address from when you sent me a stack-type trans cooler. Anyway I am surprised you say it is difficult to have a trans cooler in the radiator? I have a Walker (copper) radiator that came with a trans cooler in the bottom. I went through an argumentative experience with a transmission shop that repaired my first 700R4 after I left it dry for 5 years and the valves rusted up. That shop would not guarantee the replacement trans they installed unless I had extra trans cooling so they hooked up my under-fender cooler in series with the bottom part of the Walker radiator. I would guess the 1934 style radiator is bigger than the 1929 radiator so you might not have as much of a problem as I had. I now have dual 1650 cfm fans on the radiator with one on all the time and the second on controlled by a thermostat. This set up necessitated an electric water pump. I really did not want an electric water pump and that is where the situation developed that in order to get my car out of that shop I had to let them do it their way! Anyway I have run all summer since then without overheating so the complicated set up they installed does work. Maybe you could check with Walker Radiators about a trans cooler in the radiator but that still does not answer whether your single puller fan can cool both the radiator and the A/C exchanger. I am glad I was able to test my cooling setup in the hottest July days and now in cooler weather it runs fine. If your present fan set up runs at 165 F as you say that is a good sign but cross your fingers and you really won't know until next July whether you can run the A/C. I think my temp gauge reads high because an IR thermometer reads some 15 F lower at the top of the radiator and it gets up to 215 on my gauge in July with a 17 psi radiator cap but yesterday I took a 63 mile run up to Bowling Green (Va) and back and the gauge never went over 200F. The catch can seems to behave OK so I think my gauge just reads high using 50/50 Prestone. So other than to just renew conversation after almost five years all I am saying is that you should check out the Walker radiators although a new one may be in the $650 range.
