I 100% concur that many/most Panteras need a little to no modifications. 👍
My vehicle had 2 modifications, vent on top of the radiator (diy) and split pass copper brass radiator (per TSB) I do not know for sure if it suffered overheating issues but from what I see it most certainly suffered from wide fluctuations of the temp gauge from the location of the sensor and trapped air. With no additional temp gauge and no hand held infrared temp sensors readily available 30 years ago who really knew?
If the car was in good operating condition and a driver I would probably do no other mods than what was done but that's not my case. My tanks were rotted out, hoses toast, coolant tubes toast and crusty OE style WP
So my case is- what the heck I'm already in there. The patient already sedated may as well do it now.
Other than these "helpful" mods to build in a level of margin -("I think that was a loose quote from Boss") a dual pass radiator, better fans, take the load of the fans off of the ignition by adding relays, possibly moving the temperature sender to get better accuracy, putting in a bleed so you can properly/easily fill the system and keep air out of it, Make sure the thermostat's correct with the restrictor, make sure the hoses don't kink and have internal support or solid enough hoses as to not collapse, possibly a water pump with better impeller, under drive pulley- not sure if I missed anything lol)are all helpful 😁👍
David, thanks for the advice. I will drop or raise the tanks to change the level of those two tubes.
