You can either take of the head and repair this properly/mechanically…or pour a bottle of Blue Devil into the system and drive on… Follow the directions to the letter on the blue devil however. its really steam not smoke…Īnother symptom is that your radiator hoses will seem over pressurized if your head gasket went bad…gaskets go bad in many different ways…and I am describing a cylinder pressure leak into the water jacket type of failure…cylinder pressure will leak into the coolant system and over pressurize the radiator…then leak back into the cylinder and be burned. Do you see Puffy white clouds of smoke/steam out the tailpipe? If your engine is fully warmed up…you should NEVER see steamy “smoke” out the tailpipe.
SO if you are losing coolant…you are more than likely burning it. Look under the plastic baffle in the wheel house and youLl find it covered by dirt and salt. I live in Ontario Canada and vapour return tubing was rusted where it passes thru the LH rear wheelhouse to connect to fuel filler tube. 1999 Pontiac Montana 120,000 mi, Visitor. Coolant will NOT simply evaporate by sitting on the engine itself. Replaced cap yesterday and light went on again today.
