I have a 97' Mountain Max that always seems to run hot. I have to constantly run through dep snow to keep the running board radiator cool. Today I took it out and our trails are hardpacked, I drove about 10 minutes and the thing blew boiling the overflow tank over. Do these sleds always run hot or is mine an abberation? Maybe it needs a new water pump, but the running board radiator seems a lousy system. I may just get rid of it and get something else its such a frustrating machine, always something.
