Attak Overheat at -14 F?

Good responses so far. Ice scratchers seem like the solution on rock solid trails, helps hyfax too.. I've been meaning to get some. Short of that, here are a couple of work arounds.
Let the guy in your group with studs lead. He'll break up the hard trail. Follow in his tracks.
While you are waiting with a hot sled, throw some snow on the running boards. that helps with engine cooling , but not so much for hyfax.

Scratchers are the answer for overheating and hyfax wear, I run for ever on a set of hyfax 6000 to 8000kms no problems I even ran a GLARE ice lake once for over 2kms with no issues

i was over heating a few weeks back to

how hard is it to change the fluid in these? (any tricks)
heard an air bubble can be a real pain.

When its that cold, the trail is so hard-packed I don't think enough snow is getting pulled off the trail to cool the sled down. I would constantly run through some some powder on the edge of the trails which seemed to do the trick.

Bingo! Also, many trails in the UP require long bursts down ploughed roads with little lubrication and snow getting up to the heat exchanger under your running boards. It doesn't matter how cold it is outside.

Don't forget...scraped down to bare pavement and gravel whenever possible too.

Besides all of the answers above, which are all accurate, especially the coolant mix, I've noticed a lot of times when it gets that cold, the snow melting off the heat exchangers will actually freeze up about an inch or two right below the exchanger, creating an air pocket. This in turn, blocks any fresh snow from ever reaching the exchanger, thus no more cooling. Sometimes when it's that cold, it doesn't hurt to knock off the ice and snow under there every once in a while. Just another thing to look at.

This what would happen with my Warrior. When it was really cold a snow/ice dam would form up on the tunnel and block fresh snow from hitting the front exchanger and the sled would overheat.

If you install scratchers, don't forget to lift them before backing up! ;-)
