i have my 2012 for about a month now. It had 1 mile on it when i took it out. It did pretty good.
The next trip i went out on, i didnt wash the mud out of the fan from the previous ride too good and my temp light came on. I killed the motor then noticed that my fan motor had melted the plastic from the fan shroud. I bought a used one off a 4 wheeler and it has worked great ever since. Just make sure you keep you fan and radiator clean.
