So my lly has been giving me a low coolant light and water in fuel light the last week or two. Coolant has been coming out the top of my expansion tank and my top radiator hose is a bit stiff in the morning. Along with pressure in the expansion tank in the morning as well. Typically I’d assume this is just a head gasket, but the uppipe to my egr cooler is clearly leaking coolant because there’s residue all over it in the back. I also took the cross over pipe off the egr valve and there was considerable puddling in there. I have a delete I can throw on, but I am not sure if the low coolant is because of the egr or head gasket. Help lol

Delete it and then prepare for headgaskets.
