For 4 yrs, I had issues with my 09 overheating. I have the Trail Tank, and 1.75 lug. I tried different scratchers, but would still have to find some fluffy stuff to cool my cooler. Mine would even overheat on trails with soft loose snow at times..very frustrating.
So, I'm not 100% if this solved my issue, but since I installed a Viper snow flap, and summit seeker scratchers, (the kind that drop down from under the foot boards), on really hard (almost icy like) conditions, I've yet to see my light come on in any poor conditions.....go figure. Only other thing I've done to my sled is add Duponts, new Ski Doo idlers all around, and spray Fluid Film under tunnel before long weekend rips.
