If you were up at Greenwater this weekend

You saw my sled on its side leaking coolant. I must have picked up a rock and thrown it through the front heat exchanger. Punctured a hole in it the size of a quarter. I know its common for people to throw studs through the heat exchanger, but a rock. Dunno, at least 3 feet of snow on Sunday so its kind of wierd. Anyway, trying to decide the best way to fix this. Can I get somebody to aluminum weld it closed? In order to change it, say I bought a new heat exchanger, is there anyway to do it myself without having to pull the track? I need some advice here as my sled is sitting in my truck waiting for me to make a decision to take it to the shop or do it myself. The bill is not looking good, explaining to the wife right before Christmas I need to get this brand new sled running again is not going to go over well. Its an 05 Renegade 600 ho sdi. Thanks for your help!

Should be able to weld it. Might have to grind some fins off in the area to get a nice flat surface but it should be possible to weld a flat piece over the area to seal the hole. This is one thing that I've never had to do so not a lot of experience. I JB welded a hole about the same size in one of our race cars, it held, it doesn't look like a pro did it, but it only cost about 5 cents to do it. Permatex makes a similar product that has up to 3000 PSI tensile strength. I'm not recommending this route though, you'd be better off getting it fixed professionally by a welder IMO.

I'm really not sure what the inside of that thing looks like though. Does the coolant just fill up the entire radiator or is there tubes that run inside of it? I'd be scared if its tubes to weld it, then find out the coolant isn't getting through the tubes, overheating and blowing the engine... I got a guy that can weld it, question is.... will it work without causing more damage? Anybody seen the inside of these radiators? Is it just a hollow case that fluid flows in and out of? Thanks very much...
