My coolant tank keeps bubbling hot air from the radiator making gurgling sounds and starting to overheat after I added coolant. Just got the SUV this summer so not sure what to do.

Hi,

I would start with testing for a head gasket issue.

There is a chance that it has an air pocket but if there is a never ending bubbling then this is pressure coming from somewhere. Most common issue is a head gasket so I would eliminate this first.

Let me know what you find. Thanks
