Hey everyone. Been a while but got an old issue. It seems that the Jimmy is losing antifreeze slowly from the overflow bottle when it is not running, especially when it gets really cold. I had a shop do a pressure test a few months ago and they found no issues. I do get a very very faint smell of antifreeze under the hood sometimes but not often. I also get the steam out the tailpipe but it seems to be the same I have always gotten in the winter especially when it is parked for a long time. It only has 128k on it and the intake gaskets were done about 5 years ago. I have green antifreeze in it now. Any suggestions? It seems to drive just fine and I do not see any evidence of antifreeze in the oil, so not sure if it is a head gasket. Could this just be a case of the overflow bottle leaking somewhere? Thanks

Edit: T/stat, water pump were also replaced a couple years ago. Hoses look fine. I sometimes also get condensation on the oil cap but no oil/chocolate milk mess.
