Avoid damage! Using incorrect coolant mixture can
damage the radiator:
-
Do not operate engine with plain water.
-
Do not exceed a 50% mixture of coolant and water.
-
Aluminum engine blocks and radiators require approved ethylene
glycol-based antifreeze.
John DeereCool-Gard coolant is recommended when adding new coolant to the cooling system.
Follow the directions on the container for the correct mixture
ratio.
Close all drain orifices and fill cooling system to specification.
-
Cooling system capacity—3.7 L (3.9 qt)
-
Install radiator cap and run engine until it reaches operating
temperature.
-
Stop engine and check coolant level. Add coolant if necessary
-
