Heat Exchanger Hole

[kingedwards99]

I did a post where yesterday my sled was overheating, well today last night I put it in the garage and let it thaw out and today i decided to put some coolant and see what was going on. To my Suprise, I poured some coolant in the radiator and started to see it was going right to the floor, so i looked and seen a gauge in my heat exchanger from i'm thinking a stud. I have been running studs since i've had it, going on 3years now, and i know the track is tight enough other wise we all know it ratchits, this year i put on a 4th wheel kit and had my shocks recharged and revalved, but i noticed a stud that was pulled out along with the track and flipped over it you know what i mean. So i'm thinking it was this stud that did it in, now i'll have to bring it to a radiator shop and i hope, i really hope they can reach in and weld it with out taking off the susspenion, track, etc. there is a couple of inch of room. I am a little worried about my engine i ran it until it shut down and the oil was pretty darn hot, I plan on changing the oil, after i get it welded, i after it shut down on the trial I started it up and moved it off the trail because i was over a hill, i was toed back to the bar and it sat for 2 hours until my ride (trailer) got there, i started it and loaded it up, shut it down right away, then when i got home i started backed it off the trailer strait into the grage. Does anyone know if these sleds have some kinda saftey in them, like when it gets 2 hot it will shut down before it harms the engine any? I heard skidoos have this and you need to have them remapped if something like this occures. When All is done i plan on checking the compression in it does anyone know how much psi in the cylenders there is supposed to be. Thanks for any help. PS i'd ride with out studs if i could i only have 96 as it is but when you ride on trails and ice with others its dangerous. Any other suggestions to see if the engine was damaged?

Yes, if they get to a certain temperature they are supposed to shut down... not always though.

Glad to see you found your problem... What kind of studs you running and how long.. I believe it is a safety feature to shut it down if it gets to hot. If it sounds alright, then you should be good. Fixing the heat exchanger... If it was me, I would take the track off... I doudbt he can do a good job without getting in there right... I also would take it to a good aluminum welder before a rad shop...

in my neck of the woods there is hardly anything around.

I don't believe that the engine is supposed to shut down while riding. If it was idling on its' own and shut off, that's different, but not while riding.

I overheated as well-don't know why as I'm holding pressure but my sled did shut down while riding?Oil tank was hot as hell. Can't be good for the life of this motor. Got me bummed too.
