I have minor coolant leaks from the radiator hoses, the top hose and the small hose, on the top corner. I know they are to be "screw-driver tight", but how tight is that? I consider mine tight but it still have annoying minor leaks. And I don't want to tighten it too far that would cause premature factures.

Hoses and radiator are both 10 months old, after the neck broke...
