i was just wondering why snowmobiles stopped using radiators under the hood and switched to heat exchangers.
benifets with radiator:dont have to go through snow to make it cool down, can ride in less snow then you can with heat exchangers i was just wondering?[?][?][?]

Much of the answer probably deals with the fact that water, in this case snow, can absorb more heat than air.

John Deere Liquifires and Liquidators. I know the Liquifires had a combination radiator and heat exchanger at the front of the tunnel. Great engineering for the 70's and 80's.

[^]Kawasaki Invaders had radiators too. A radiator requires movement to pass air over it. When you stop...no cooling. This came into play in the world of racing. Sleds would be on the line waiting for the start and temps would rise to dangerous levels or puke coolant awaiting the green flag. So, the racers started adding exchangers along with radiators and soon realized that the exchangers alone were efficient enough to do the job.

Exciter man a set of ice scratchers may work for you. They are springs that either attach to your skis or your suspension that drag in the snow or on the ice and keeps the snow dust going over the coolers. They also work well to keep the hifax from sticking. Riley
