Look into Northstar head gasket problems.


Try purging the cooling system from air, if you have not already done so. Here is a video on how to purge your cooling system...https://www.youtube.com/watch?v=zUpXgAJ1gjU

Thanks going to have this done going thru almost a gallon of antifreeze a day and no water in oil or under car. Starting with cooling system and overflow, overheated the other day lifted up release on radiator cap and the water was coming out of overflow like a waterfall.
