[AT] Cleaning out Tractor cooling system

[Wrench50 at aol.com]

I have used Iron Out in the cooling system of my Case 500 diesel with good 
results. The cooling system looked like the PO had filled it with well water 
each time, than drained it at the end of the day. It was really full of rust and

found in the laundry soap area of the super market. It's used to get rust stains 
out of cloth.     Del
