The only downside is their lack of high horsepower and consequent response when you pull the trigger. Fan machines have fewer downsides than do the liquid cooled machines. You can run them on icey trails and mixed terrain after the snow has gone or before it covers well if that is your thing. They weigh less and have fewer reliability issues with no coolant system to spring a leak, no pumps to run, etc. The LCs are quite reliable don't get me wrong - and powerful, which is what the LC guys fall in love with: power, to the exclusion of their sense about what is reliable.
I have ridden well over 50,000 and likely closer to 100,000 miles on fan cooled machines. I have run over 300 miles in a day on them and have pulled loads over 1000 pounds many times with them. I must admit I am in awe of some of the trick aerial stuff people do with snowmobiles. I think, however, that many folks would be surprised to see the "tractor pulls" that happen when people put snowmobiles (snowmachines), many of them fan cooled machines, to work in the arctic on a daily basis.
Don't be afraid to consider a fan unless getting there fastest is your first priority.[/b]
We experienced the same thing, except switch it around. Everytime the FC sled overheated, the LC sleds just motored on. Until dad traded in the FC sled for his very first LC sled for that reason. 2 years ago, I'd be arguing against LC sleds. But they've managed to out-perform every time in the past 2 years for us.Everytime I overheated this winter on my sled, the wife just motored on with her fan cooled sled... I just wish they could supplement the heat exhangers somehow for low snow, hardpack conditions on the LC sleds[/b]
I've ridden in cold conditions, if -20 F is cold, where L/C machines were overheating and breaking down. Does the same logic applied in reverse mean F/Cs are superior?The LC does have more benefits than the fan, unless you are driving slowely and don't care about HP. We have ridden in warm conditions, but there was plenty of snow down for the LC to stay cool; while witnessing numerous FC break down.[/b]
Most LC sleds are lighter than FC sleds. This wasn't true until the past few years when freestyle sleds and high performance sleds became high in demand. Their chassis and counterparts were made lighter, so although the coolant system is added weight, the overall weight of the sled is much lighter than the FC sleds.[/b]
Not true. They are still a bit heavier even though they have come down overall in dry weight.[/b]
