And I know many have opinions about this, and if Tajon has enough time and money and wants to try this out, it's a free world, sort of...
But I'd hate other readers with perhaps cooling issues to think this is the needed way to go. The standard Pantera cooling system is OK with very few modifications. Case in point, my own Pantera, 600HP, driven around France in 30+C, gone straight from highway speed to city queue, A/C on: No cooling problems ever.
So here are the requirements for those who would like to know:
WAD (=Working As Designed):
-No leaks, no air pockets. Test with test gauge, must hold pressure for an hour
-All hoses double clamped
-All hoses/tubes clean inside
-Proper Cleveland thermostat, nothing else
-Normal Weiand or similar water pump
-DO NOT move your A/C radiator up in front of engine radiator
Upgrades:
-Replace small inefficient pusher fans with bigger modern puller fans behind radiator
It works.
I have one fan on a thermostat switch and one on a button on the instrument panel. Works like a charm. The thermostat turns on a fan rarely, mostly if standing still after freeway speed on hot day. The button is just used by me for feeling secure, don't think I've needed that #2 fan yet.
