U'll need to take it too a welder or find somebody with a tig or spoolgun.
Spoolgun would be fastest my opinion.

Think Snow!!!!

You want to have it tig welded. Spool gun welding for thin wall is not recommened at all. Tig is the best welding process for controling the size and depth of the weld bead. I've tig welded just about every piece of aluminum on sleds that encounter stress, vibration, and heat. Just make sure whoever welds it has a tig machince that can control frequency and balance of the weld, thats for getting into extremely tight spots on the heat exchanger without damaging other fins.

I have 1000+ miles on mine and 700+ on my dads with both aluminum mig welded, no problems. STUDS... are the problem

Tig would be the best way to go and you will need to give them good access to the spot, if it is the front exchanger that means pulling the suspension and track. If you want to get back out riding fast and have a warm area to keep the sled JB Weld can do some amazing things, don't know that I would want to make it the long term fix but it should get you through the season. Just make sure the area is dry and clean before you apply it and keep it in a warm area overnight to cure up.

Jb weld

USE IT!!!!!! I used JB Weld to fix a bigger hole in a crack in a ford 351 coolant line, a crack on my oil reservoir on my summit, as well as heat exchangers!

For the time it will take to pull the skid, take it to an aluminum welder (and a good one at that since the metal is so thin). You could be back riding in 24 hours with JB Weld and a salamander heater! Even if it leaks a little - you can always add more JB - the worst that happens is it turns into a small leak rather than a big one!

Blutooth- We should bring some extra along for the Super Snodeo next weekend. There's a good chance some repairs will be made....

Kool Aid anyone??
