I have had five Panteras with the following radiators:
1. Hall Phoenix (copper) - Worked great. Heaviest radiator imaginable.
2. Fluidyne five row with shrouded puller fans. Works great, still have it.
3. Stock radiator with upgraded fans - Worked great, better than I expected. Sold the car and new owner drove it home 300 miles on the hottest day of the season without a problem.
4. Stock radiator with stock fans - Works great, current owner of the car is suspicious yet continues to use it. It's an original Pushbutton car and I keep encouraging him to stay with it. When I talk to him next I may suggest he keep the radiator, upgrade the fans, and put the originals in a box.
5. Pantera Performance Colorado - Works well except that it is leaking. Has an integrated shroud and fans. Made by Ron Davis. It runs a little hotter than I think it should but temp is okay. This is the one that is currently leaking and I would like to fix it if possible. Suggestions are welcome.
