My 1k keeps overheating it’s brand new less than 10 miles on it, I have checked the coolant it is fine, it will heat up to 250 degrees quick i will shut engine off an it cools down but quickly over heats again, I had the dealer install a heater an have tried running it but it still over heats. Any ideas on what could cause this. New member BTW just bought my new RZR an not happy at the moment
