My parts guy is really hot on Engine Ice "high performance coolant". Apparently it's just propylene glycol + additives and doesn't appear to be exactly magic, but some Yammies have a little tendency toward overheating and I'm curious if any of you guys have experience with it, and if this represents some kind of advantage in snowmobile use.

The down side to "Engine Ice" and "Water Wetter" is that they break down much sooner than normal coolant. Count on replacing yearly. Up side is that these products do work, and are required at most race tracks IE asphalt/concrete

wonder why so many yamahas overheat? maintenance ? radiator caps should be replaced every other season.it's a lot cheaper than a motor.it still amazes me how many people won't replace them on cars.caps do wear out.i had two people with toyota trucks this year call me wanting headgaskets replaced.turned out it was just the radiator cap.lucky for them i'm honest and know what i'm doing.if you have no leaks and your loosing coolant and overheating,try a new radiator cap.

I think it's just inadequate heat exchanger surface area.
A new cooling system cap is about $37. Yikes.

From what I found out, it's mainly used for MX bikes - snowmobiles (in winter) not so much. According to the factory rep, the stuff starts to slush up at -23 degrees F, although it won't freeze solid and won't expand until about -50. Nevertheless, might be some coolant flow problems in the morning after those -30 degree nights.
I've put that one in the "not such a great idea" file.
