Why is coolant in my radiator filliing up my overflow tank
4 Answers
It could be the radiator cap not holding the pressure. If you see bubbles as it fills the reservoir, it could be a blown head gasket.

I'd look at two things...the condition of the underhood area for evidence of a prior overheat and whether or not "PANIC" plain water was used never to be replaced with proper 50/50 mix...yet~?
