common problem is over tightening - strips plastic plug threads so they
can't hold properly under pressure. more likely that's what's happened.

remove plug [keep finger over hole to prevent total coolant loss] and
examine threads. if damaged or stretched, buy a new plug and /gently/
screw back in. the rubber gasket makes the seal, not thread pressure.
