Could easily boil dry with a less poundage cap.!
Not a good idea.

So I have a theory as to the cause and its linked to the weeping I used to
get on shut down (from new) and the split pipe I had over the radiator
junction. The radiator wasn't leaking in flight, it started when I shut
down. When the water pump stops working and the engine is hot, from landing
with the prop on fine and highish revs, the pressure builds up at this end
of the radiator. Now I have clamped it all up and stopped any leaks its
found a weak spot in a rad weld and made a small puncture. 
I wonder if the cap needs to be a lower pressure one so it vents properly
instead of knackering the rad?
