1990indy500

Just bought a " fixed up" 1990 Indy 500. Took it out today. It was about 25 degree f or -2 c. Took it for a rip and 15 min in the antifreeze recovery tank was steaming out. Could it be my t-stat or my water pump be the problem? The water pump belt is good. Sled idles at about 2800 which I think is way too high. We have about 12 inches of snow so I don't think that's the issue. Any pointers would be appreciated. Thanks
