Supercharged
Mine started to puke coolant out the the overflow tube ahead of the rear wheel when I parked it. Just a bad rad cap. I ordered the OEM part, but the caps sold by Moose Racing for quads fits too. I stole the cap off my LTZ for a week. I had the red 23psi model and the Rocket's stocker is 16psi. Sure ran cool that week. I don't know if the R3 system could handle 23psi for the long haul.
Bennys video is the closed i've seen helping those with the coolant system. I bet if someone did a how to video on the coolant system a lot of newbies would appreciate it.
