I've got a 95 Acura legend with cooling issues. I recently replaced a cracked radiator and the thermostat while i was at it, but the coolant is boiling before the thermostat opens so I can't burp the system. The temperature gauge on the dash reads just under half, but the system is boiling over.
My first guess was a busted head gasket, so I checked for exhaust in the coolant with a chemical block tester but it came back clean, I have no coolant in my oil, no white smoke/moisture in the exhaust and the cooling system also hold pressure like it's supposed to.
Any ideas? I'm at a complete loss on what to do next.
