Got this from a tow yard hoping to be able to take care of it.

We had redone all the fluids, new ambient air sensor, new thermostat and hosing. This van doesn’t have a check engine light and drives like you wouldn’t know something is wrong.

But something is wrong.

Coolant is pressurizing and coming out of the radiator cap. The van has not overheated.

So at this, if you’re a mechanic and you’re confident, you can fix a head gasket easy. But also, I could have overfilled the coolant, or there could be a bubble. This van is solid but I am paranoid and refuse to break down on the side of the road.
