Very hard packed trails or lakes (no loose snow)caused my Apex to overheat even in very cold temps. until I put on the rear heat exchanger, dilluted my coolant, and added Water Wetter.
I have not overheated since I did these three things. I can not be sure since I did all three things at the same time but I think that the rear heat exchanger probably made the biggest difference.

I stretched out my RTX this year to 136 and added a huge rear cooler. This year, my sled runs 25 degrees cooler on average. I havent even been close to overheating. The hottest I have seen the temp gauge is 180. Rear coolers help like crazy, and the bigger, the better.

I added the small Apex rear exchanger to my Attak, have not had an overheat indication since. I have run long distances on hard icy trails, no problem.
I am running 1.375 studs, and modified the stock tunnel protectors to allow clearance for the heat exchanger. Cut off the stockers in front of the new exchanger, used existing holes to bolt new 1" square aluminum stocks and extended them back over the exchanger. Also added some HiFax to the extensions. No rubbing / not studs hitting. The new extensions are bolted up through the tunnel tail extension similar to the 2009's. Used a block to space between the tunnel and the new protector extensions. The advantage of doing this versus replacing with new Yamaha protectors is I didn't have to remove the seat and exhaust system, and I saved $150.
