I was riding my 08 Nytro around Mercer today and got off the side of the road in the deep powder and got it stuck. I put sled in reverse and rocked it a few times back and forth to get it out, I heard a bang noise in the track after I got it out I road a few miles and the temp light came on, I pulled it in and there seems to be a hole in the heat echanger. My questions are is the heat echanger on this model only for coolant or is there an oil cooler up there also and the next question how hard are these to change. I think my riding is probably done for the week I am afraid.
