my '02 600 xc has run great the couple of times that i have had it out this year but it loses coolant. now there are no visible leaks in any of the hoses that i can see when its running or when i shut it off. when it had not been run for a few weeks i filled the level up to the cold line and ran it in my yard a little, it blew all of the antifreeze that i put in it out the breather tube. so i left it at the level it was at, rode it for the weekend it never got hot, but now its leaking a litte out of the belly pan and the level is about 2 or 3 inches from the bottom of the jug after i released the pressure by loosening the cap on the jug. any suggestions anyone. (i don't think that sounds like a head gasket, am i wrong) if so what else could it be.
