James Price Haven't seen one of those in a long time,that big radiator is really a powerful cooler my big chevy never offers to overheat with the same thing,except just the cap. Good luck with your fix . You know with that tall ( above the coolant) neck if it is pressure cap friendly couldn't you protect it there ?? Might need to install (sweat-in) an overflow tube with hose. Just a thought.
