hey I have a 2012 m800 pro climb and my heat exchanger has cracked on our last trip. The tab that is welded on top where you motor mount is attached to has cracked and was leaking coolant . Has anyone else had problems in this area? I called my dealer and waiting to see if its covered under warranty. If not else we will try and weld it up! Also could a person swap it out for the 2014 short cooler?
