I recently overheated my 4ac corolla... its been running in high temps and today i noticed that the water bubbles when the caps off
I know this is REALLY bad news having done it before, so i put a pressure tester on the radiator and gave her a cranking to 110PSI (yes i know its higher but im very annoyed)... The pressure DID NOT DROP
Does this mean that the head is blown? why wont water travel back into the engine?
NOTE this is bubbling with water, havent tried coolant... would it bubble if its just normal water
