There wasn't one (a weak link), it just doesn't have hot spots that cause
localised boiling. I can remove the cap on my 73 roadster immediateluy
after a run with no risk of scalding, but woe betide me if I try it with my
V8 before the temp gauge has risen then fallen back to 'N' again. When I
first had the V8 it always used to vomit a bit of coolant after a run, until
I fitted a new cap.
