Ok first of all you need to know that I am totally a car guy and completely ignorant in the world of snowmobiles. Anyway my brother bought a new Polaris X-Edge 600 or something like that and said if I wanted his old Indy 500 then to come and take it and get it back together, so I did. Its a 95 I THINK. Anyway I took it out today for the first ride and took it about 2 miles before it just cut out on me. I popped the Cowl (this is where my ignorance shines) and looked and saw that the piece that the radiator cap looking thing goes in to had cracked completely and was laying on top of the engine. Ill try to explain better. On a car you have a radiator cap andd it looks similiar to this but there is also a lever to lock it on the sled. The piece that comes out of the engine which this cap screws on to had cracked and come completely apart. I set the piece back where it belongs and waited about a half hour at which point it restarted and I was luckily able to get out of the woods and back to the gas station where it then cut out again. The engine was clearly overheating and when I took the cap off there looked to be no antifreeze in it, Im not sure if you can tell this way or not. I went to the gas station and bought some to pour in. I cant get it started now at all. I know I will need to replace the piece that broke but any ideas what else I could do or any other stuff that maybe I screwed up. Thanks in advance.
