Fuels, Lubricants and Coolant IMPORTANT: John Deere Liquid Coolant Conditioner does NOT protect against freezing. CHECK EFFECTIVENESS OF COOLANT SOLUTION Prior to the recommended change interval or if concentration of coolant solution is in question, a coolant sample should be taken and a COOLSCAN analysis performed. G DO NOT over-concentrate coolant solutions with supplemental coolant additives, as this can cause silicate-dropout. When this happens, a gel-type deposit is created which retards heat transfer and coolant flow. DO NOT use soluble oil.
COOLSCAN is a John Deere sampling program to help you monitor the effectiveness of your engine’s coolant solution and identify potential problems before they cause serious damage.
