Not sure what the temp was when boiling over, has to be well over 100c first time when it dumped 1 gallon. it is bmw coolant 50% mix... Re read first post, diagnostic temps are after the boil overs happened... Pure distilled will boil at 120c under normal bmw coolant pressure. Thinking it's the cap
