Fuels, Lubricants, and Coolant/Engine Coolant Requirements ALTERNATIVE AND SYNTHETIC LUBRICANTS Conditions in certain geographical areas may require lubricant recommendations different from those printed in this manual. Some John Deere lubricants may not be available in your location. Consult your John Deere dealer to obtain information and recommendations. Synthetic lubricants may be used if they meet the performance requirements listed in this manual.
02 5 DX,ALTER -19-01FEB94 ENGINE COOLANT REQUIREMENTS RG6258 -UN-22APR92 A—Quality Water B—Ethylene Glycol Concentrate C—Supplemental Coolant Additives (Antifreeze) (SCA’s) Engine Coolant To meet cooling system protection requirements, the coolant MUST consist of a 50/50 mixture of quality water and ethylene glycol concentrate (antifreeze). Supplemental coolant additives (SCA’s) must be added to this mixture. Add 3% (by volume) TY16004 or TY16005 Liquid Coolant Conditioner. If an equivalent product is used, always follow the supplier’s recommendations printed on the container. See ENGINE COOLANT SPECIFICATIONS, later in this section, for further definition. IMPORTANT:
Supplemental coolant additives MUST be added to the coolant solution. Ethylene glycol concentrate (antifreeze) DOES NOT contain chemical inhibitors needed to control liner pitting or erosion, rust, scale, and acidity. Makeup of the coolant between changes MUST consist of the same requirements as during a complete change. Performing a CoolScan analysis is the recommended method for determining the amount of quality water, ethylene glycol concentrate, and supplemental coolant additives that should be added.
