Haven't been able to get antifreeze so I been putting water in the cooling system for the mean time


do you have or know someone that has a sniffer/emissions see if a head gasket is blowing into the water?




I had someone look at it & said everything is fine but think the thermostat needs replaced again .


The slower I drive the slower it takes to overheat & wen its not even overheating wen I shut the car off its bubbling really bad .
