Water leakinging from reservoir cap.
I have a 2002 Camaro 3.8l auto, and saturday after my mom had just gotten back from driving it noticed the water was bubbing in the reservoir and being pushed out of the cap. The whole cooling system was replaced, all the hoses, radiator, reservoir, pump, belt, thermostat, everything replaced last summer. I did all the work myself and since then I haven't had a cooling problem or any problems relating. I asked her how was the temp when she drove it but she didn't look at the gauge. So my question is what would cause the coolant to boil/bubble in the reservoir and be pushed out of the cap?
Thermostat stuck, blown head gaskets, cooling fan inoperative.
