same exact thing happened to my bud's 800 outty this summer. replaced the rad and some sort of mod to the cap on the overflow to allow pressure to escape.
Had the same thing done on my 07 800 xt max under warranty. The rad had expanded and closed of most of the air flow. I think the new modification to the overflow tank cap, will solve the problem of the expanding radiator for good.:d
