Antifreeze coming out of overflow on 2011 Summit X

[Powder hound]

We were up riding this past weekend and all weekend antifreeze was coming out of the overflow. Everyday I lost antifreeze and had to fill up the overflow bottle as it was almost empty at the end of each days ride. It appears that there is excess pressure that is going thru the bottle. Anyone have any ideas on why this is happening?

My first thought was airlock but now I'm thinking maybe a head gasket.

thermostat issue?

Pretty much guarantee its a head gasket. Take your head off, should be o-rings around each cylinder. It's allowing compression into your coolant.

2000mile burn down beginning??

Not trying to be a dink, but quite a few doo's that I have seen(my self included) have antifreeze leaking from the overflow just before dropping cylinder. Head gasket quite possible.

Is there bubbles in the coolant when it's running?

2011x would have the piston recall. How long since the recall. Did they fold a gasket maybe?
