I'm confused. The 9N hood was not hinged. It has 3 small rods at the top that align with 3 holes in the hood.
If your 9N has an 8N hood, that is hinged. Even then, I don't see how "slamming it shut" would poke a hole in the radiator. Something isn't right.
As for the radiator damage, JMOR has it right OR you can take it to a shop OR buy a new one.
