cooling

hey folks I busted my radiator over the weekend on my 2016 1000-5. I found a used radiator off of a 2017 on ebay for about $70 less than buying new but see that the 2017 and up have a different part number than the 2016. Can't really see a difference in the pictures so I was wondering if anyone...

Has anyone ran a duct into the engine compartment with a reversible fan to provide engine cooling in the summer and reverse it for heating in the winter? Or if this is a bad idea your imout would be greatly appreciated! Troy
