I replaced the 16 tecunseh in my argo 8x8 1981 vintage with a 20 hp Kohler magnum. The extra heat generated by this motor has me a bit concerned. I have a two speed blower fan that will not keep up to the extra heat this not under load just cruising down fairly flat trails and some mud puddles. What can I add to help with the temprature thing? Blower motor from a truck? More vents? Remove the hood during work periods? When I start working it to fetch my moose in some cut block a melt down or cease would be a disaster! Any ideas would be greatly appreciate.
