Have a 98 powder special I put a new top end in over the summer. Rode it on day ran great with no over heating problem. Rode two days later get about 10 miles and sled starts to overheat, no circulation and blowing steam. Remove thermostat housing wide open, add water and seems to cool take off and she overheats in about 100yds. Can the water pump impeller not turn and still turn the oil pump. Or could it be it just had an air bubble.

I just went through this with my ultra and I am still not sure I won. Yes the impeller can wear out and the oil pump still works. You can have a bad radiator cap, stuck thermostat, collapsed or plugged hose, leaking head gasket, missing snow flap, if you extended your track the exchanger might be in the wrong place...or an air bubble...good luck

raise the front of your sled up a few feet and top it off with coolant. sometimes the coolers get an air bubble in them and the only way to get it out is to bleed it or make it rise to the top. once you are topped off, warm it up and feel the coolers........are they getting warm?
