John Deere Low Silicate Antifreeze is concentrated and should be mixed minimum 40% - maximum 60% antifreeze and distilled to deionized water.
Consult your John Deere Parts Network for local availability. If Chlorides, Sulfates, or Total Dissolved Solids are higher than the above given specifications, the water must be distilled, de-mineralized, or de-ionized before using in cooling system. If Total Hardness is higher than the above given specification, and all other parameters are within the given specifications, the water must be softened before using in cooling system. Ethylene Glycol Concentrate (Antifreeze) IMPORTANT: DO NOT use methyl alcohol or methoxy propanol base concentrate. This concentrate is not compatible with additives used in supplemental coolant additives.
Damage can occur to rubber seals on cylinder liners which are in contact with coolant. DO NOT use ethylene glycol concentrate sealer or stop-leak additives. ENGINE COOLANT SPECIFICATIONS DO NOT use concentrate containing less than 10% ethylene glycol. Water Quality DO NOT use concentrate containing more than 0.1% anhydrous metasilicate. This type of concentrate, which is intended for use in aluminum engines, may cause a gel-like deposit to form that reduces heat transfer and coolant flow. Check container label or consult with supplier before using. Distilled, de-ioned, or soft water is preferred for use in cooling systems.
Mineral (hard/tap) water should NEVER be put in a cooling system unless first tested. However, water that meets the following water quality specifications is acceptable. G-10 4/7/95 AllTractorManuals.com TS281
