Fuels, Lubricants, and CoolantDiesel Engine CoolantThe engine cooling system is filled to provideyear-round protection against corrosion and cylinderliner pitting, and winter freeze protection to -37°C(-34°F). If protection at lower temperatures is required,consult your John Deere dealer for recommendations.John Deere COOL-GARD Prediluted Coolant ispreferred for service.John Deere COOL-GARD Prediluted Coolant isavailable in a concentration of either 50% ethyleneglycol or 55% propylene glycol.Additional recommended coolantsThe following engine coolant is also recommended:• John Deere COOL-GARD Coolant Concentrate in a40% to 60% mixture of concentrate with qualitywater.John Deere COOL-GARD coolants do not require useof supplemental coolant additives, except for periodicreplenishment of additives during the drain interval.Other fully formulated coolantsOther fully formulated low silicate ethylene orpropylene glycol base coolants for heavy-duty enginesmay be used if they meet one of the followingspecifications:• ASTM D6210 prediluted (50%) coolant• ASTM D6210 coolant concentrate in a 40% to 60%mixture of concentrate with quality waterCoolants meeting ASTM D6210 do not require use ofsupplemental coolant additives, except for periodicreplenishment of additives during the drain interval.Other low silicate ethylene glycol base coolants forheavy-duty engines may also be used if they meet oneof the following specifications:• ASTM D4985 ethylene glycol base prediluted (50%)coolant• ASTM D4985 ethylene glycol base coolantconcentrate in a 40% to 60% mixture of concentratewith quality waterCoolants meeting ASTM D4985 require an initialcharge of supplemental coolant additives, formulatedfor protection of heavy duty diesel engines againstcorrosion and cylinder liner erosion and pitting. Theyalso require periodic replenishment of additives duringthe drain interval.Other coolantsIt is possible that neither John Deere COOL-GARD norcoolants meeting one of the coolant standards listedabove is available in the geographical area whereservice is performed. If these coolants are unavailable,use a coolant concentrate or prediluted coolant with aquality additive package that provides cylinder linercavitation protection and protects the cooling systemmetals (cast iron, aluminum alloys, and copper alloyssuch as brass) from corrosion.The additive package must be part of one of thefollowing coolant mixtures:• ethylene glycol or propylene glycol base prediluted(40% to 60%) coolant• ethylene glycol or propylene glycol base coolantconcentrate in a 40% to 60% mixture of concentratewith quality waterWater qualityCoolants requiring supplemental coolant additivesCOOL-GARD is a trademark of Deere & CompanyContinued on next page10-11 060106PN=35DX,COOL3–19–27OCT05–1/2
