A friend noticed a small coolant leak while at breakfast this morning. The green smear on the frame tube and the nearby bolt are the tell-tale signs. I think the most likely culprit is that hose clamp to the top right. My coolant reservoir is still at the right height, so it doesn't seem to be much of a problem as of yet. Will probably try to loosen then tighten that hose clamp and see if it goes away for good. Anyone else have something similar happen on their machines?
