@Doug,

Well thermostat and WP are almost new, WP is less than a year old and thermostat is about half-years old. As far as I know, thermostat should be controlling coolant temperature to prevent coolant from boiling, BUT WHY did it boil??? I don't really think thermostat failed prematurely, well at least I hope so ....I'm leaning more toward aux fan..Last option would be head gasket, of course.....

@chris-alfonso
I just checked cap, o-rings were fine. I guess rings couldn't hold the pressure since coolant was boiling..

@deadpass
Absolutely don't think so, I did replace bleeder screw when this stupid thing broke..Both cap and bleeder screw are practically new, seals are just fine
