2010 M8-Sno Pro 162

[tootersp]

Just bought a brand new 2010 Arctic Cat M8 SP. Took the sled out for the second time. Sled had 40 miles on it. Let it warm up for 15 minutes prior to hitting the trails. Air temperate was -5. 4 miles down the trail the engine quit running. Took it back to the dealer and when the dealer looked at it they said the engine had a "cold seizure". Has anyone heard of this issue or had the issue happen to them?

Supper cold temps and not working the flipper enough this will happen every time. Make sure you move that flipper around alot and this will keep you out of lean spots.

If you did in fact warm it up for 15 minutes and made it 4 miles down the trail it wasn't a cold sieze.

when i had my 800 mountain cat and my buddie had the 900 the same thing happened to him twice. we both warmed our sleds up the same amount and were going down the same road at the same speed and his goes out twice. don't know what it took to fix it the second time he sold the sled.

after 4 miles it's not cold seize unless their is something else wrong which should be covered under warranty. I would take some pictures and get a second opinion from another mechanic.

i've had a couple of sleds seize doing just what you described...keeping my kids in sleds, i got educated to lots of stuff...even though you warm the engine, once you start moving, there is still a lot of stuff on the sled that needs to warm up also....and too many people think that if they just ease on down the road, that they'll be ok....not so, the throttle has to be kept busy for the first ten minutes or so.....i would say cold seize was what happened, but maybe not due to classic piston expanding into the cylinder walls scenario...with a totally clean from snow tunnel, and a small layer of very cold, dry snow, which is being kicked up and covering all the cooling area in the tunnel, it will drop the water temp much more than later in the day when some of the cooling radiators are partially blocked, and don't get as much kick up as at the first of the day...i've watched this happen on sleds that have a water gage, and watch the temp drop rapidly....combined with a sled that still has tight tolerances, certainly possible..

When I warm up my sled, I try not to take off until that rear heat exchanger starts to get a little warm.

15 min and 4 miles later is not a cold seize.

However, when its cold and/or on the trail I always braap the throttle like crazy.

After running egts on my old sleds for five years i know there are a lot of lean spots in the mid. You really gotta vary the throttle to keep the egts under 1100. You can hit 1300 in the mid quick if you hold it steady. Thats on three different engines that I felt were well calibrated.

cold seizure

snowmobile sits in 65degs. in garage. it has can on it. and yes it did warm up for 10-15 mins. drove it for 5 mins. to buddies house then hit trail. the only thing i can think of is that i didnt play with the gas enough or thermostat maybe got stuck? any other ideas? they are saying cold seizure because of markings on piston.
