[DeTomaso] Radiator

[Eric Smith]

I did install a plate for the bypass that’s under the thermostat.  I bought it from Pantera Performance back in 1990ish and was one of the first things done to try and keep it from overheating.  It had a penny soldered in the hole, completely blocking the bypass.  It made no difference at all.  Tried all the correct thermostats with different opening temps, and even no thermostat, but no luck.  I focused on air in the system after that but it still overheated.  Bought an aluminum radiator with puller fans from Pantera Performance, then installed the vents in the hood and it still overheated.  Installed a high volume aluminum water pump and it seemed to take longer to overheat but still would overheat.  I replaced the water pipes with a larger water pipe, that looks like shit, but I was desperate, and again, it took longer to overheat but still eventually did, even on a cool day.  Sent it to a radiator shop and he came to the conclusion that the engine needed to be rebuilt.  Mainly because he couldn’t find any reason for overheating.  So that’s what I did.  Stock rebuild and open chamber heads, and it still overheated.  This was back in 1991-92.  The head gaskets were installed correctly and the block and heads were inspected for scaling, then hot tanked.
  
Since a much stronger engine is about to be installed, I’m thinking I need the best cooling system possible so I don’t have to worry about it anymore.

The acid test on my way home was a couple of hours of bumper-to-bumper traffic, in 102° heat with the AC blasting. My temp gauge never got above 185°. Driving to and from this year’s Fun Rally, the needle on the temp gauge hardly moved a few degrees from cruise to stopped in traffic. I truly can’t say enough good things about this setup, and I no longer have my eyes glued to the temp gauge - ever!!!
