I have a 2012 commander 1000 Ltd, while riding last weekend i noticed the heat gauge going up higher than usually but would fall back down quickly after a bit. After about half an hour of driving it started spewing out coolant from the rad cap I believe but everything was so wet it was hard to tell. Got a new thermostat, replaced coolant and did what the manual said to get the air out. Even picked up the front with my farm tractor to about three feet off the ground.Now with no cap on rad as soon as it is started( even cold) the coolant level rises and overflows.As the temperature rises the rad will get hot top to bottom, then fan comes on but temperature keeps going up until coolant is going everywhere and I shut it off. If I feel the rad now it is cold again but the line to the waterpump is still too hot to touch. Would this be my water pump maybe or a head gasket?
