I was checking the coolant in my 1050 last night and noticed some kind of thin film of black oily type substance floating on the top of my coolant in the overflow tank. I thought if water and oil were mixing it would look foamy. What I have seen in automobiles tends to look like chocolate milk when oil and water are mixing. This looks more like soot settled on top of water. The oil looks fine, no problems there. I took the cap off of the radiator and the same substance was floating on top. Just a very thin layer. I had run the tractor for 2 or 3 hours. Could it be some by-product of combustion gases? Any ideas? Thanks!
