Since we have been going for some time on cooling system and heater
threads, I thought I'd ask a question that has puzzled me for years...
Early MGBs have 7 lb. (don't know what that works out to in metric
units) radiator caps. Most car cooling systems can run at twice that
pressure. This seems desireable, as it raises the coolant boiling
point. What is the weak link in an MGB cooling system that would
prevent you from running at a higher pressure? Radiator core? Brass
header tank metalurgy? Heater core? Heater valve? Head gasket??
Or is this a bad idea for other reasons?
