My poor Mark VIII is sitting up at the corner gas station (under the care of a trusted mechanic).
I have this great fear that I blew a head gasket - but he seems to think differently.
What's happening is that as the coolant comes up to temp - and the thermostat opens - it rushes headlong toward the poor plastic reservoir and spits up through the 18psi cap. Within two or three uses the car asks for more coolant.
Might be:
1.) A blown head gasket that is forcing cylinder pressure into the cooling system - thus creating a big SWOOSH as the T-stat opens (my fear)
2.) A blockage in the radiator that is causing the water pump to send too much coolant toward the reservoir instead of the radiator.
Michigan isn't that hot - so the temp gauge is stable - plus once it spits up - it settles down and runs great.
I'll know tomorrow - and either be really depressed - or really happy.
