My ZTU has a coolant foaming problem after it warms up. Since I did not know the previous history of the coolant, I drained the cooling system, flushed it with fresh water, then put in Prestone radiator flush
solution and ran the tractor for a while. Drained and flushed the system again before adding new antifreeze and water. However, the foaming problem persists. After the engine warms up adequately, the coolant
begins to foam and flow out the overflow tube. Does anyone have any suggestions for what may be causing this issue? Thanks!
