Have a V6 DOHC engine 24 valve 3.0 Liter auto transmission its losing coolant Thermostat working, no coolant in oil, transmission fluid ok, pressure cap been changed holds pressure. have not noticed any vapor coming out of exhaust. Coolant bubbles when I rev engine (radiator cap off) I suspect head gasket any ideas. If head gasket what is part number? can buy in Philippines, expensive. I am in states anyone know what one I could buy here to take to PI? It looks like it could be SKU #A8100 88897. I emailed Mitsubishi Philippines no answer. (please english only thanks) Help
