Needing a cross ion inhibitor for my Kubota 1120 RTV Diesel I researched different products. Decided on trying the Super Coolant. First use and impression as a coolant, my machine runs cooler. Heat of the day the cooling fan comes on less and runs for shorter periods of time. Needed it for a corrosion inhibitor, if it will work on that this will be a future product used here on the Ranch. -Thomas
