when I had my polaris midsize I rigged up a pipe and cowling and captured the heat from the exhaust pipe using a 12 volt 3'' fridge fan,with my wolverine I capture the heat from the rad by venting the consoll and a 150 watt windshield defroster for front windshield,but also have defender cab witch helps a lot.
I made it through the winter with these vents and windshield defroster and seemed to keep it about 10-12 deg. cel warmer than outside temp,i also plugged the aiflow under the consoll with matting to get better flow through the vents.Does the venting keep the cab pretty warm. I'm getting the soft cab. Like the vent idea
Ordered the same setup as you but also got the defrost kit. Going to put the other vents on the consol so they can be turned towards the feet if needed. What size of fitting did you need? 1"-5/8"?I used the summit universal car heater and vent kit. Had same kit installed on my rzr. Check out my youtube video and you can see how I installed the heater core and vents..
