Problem with coolent cap

Opened the hood and the cap was off. Don't know if there was any foul play or it popped of on my hunting trip. Anyone have this problem?

 

Never in twenty some years have I seen a cap blow off. But It’s your defense mechanism that automatically thinks fowl play. Maybe you topped it off and didn’t secure it? Or worst case scenario pressure built up, maybe from a bad head gasket? When was it serviced last, Jiffy Lube or something?

 

Any luck hunting? Rutting yet there? Pics?

 

I always fear the gremlins will mess with my scope adjustments hence I keep it locked up in a case at all times.....

 

Just bought the 4, a month ago from the dealer. No luck here in montana. Just lot of tracks and orange lol

 

Maybe the minimum wage technician at the dealer topped off and forgot to close it?
