Recommended Engine Coolant

IMPORTANT: Avoid damage! Using incorrect coolant mixture can damage the radiator:

• Do not operate engine with plain water.

• Use ethylene-glycol based antifreeze approved for use in aluminum radiators or aluminum engines.

• Do not exceed a 50% mixture of coolant and water.

• Do not pour coolant or water into the radiator when the engine is hot.


The following John Deere coolants are preferred:

• COOL-GARD® PRE-DILUTED SUMMER COOLANT (TY16036).

• COOL-GARD® CONCENTRATED SUMMER COOLANT (TY16034).

If neither of the recommended coolants is available, use a glycol base coolant that meets the following specification:

• ASTM D4985 (JDM H24A2).

Check container label before using to be sure it has the appropriate specifications for your machine. Use coolant with conditioner or add conditioner to coolant before using.

If using concentrate, mix approximately 50 percent antifreeze with 50 percent distilled or deionized water before adding to cooling system. This mixture will provide freeze protection to -37 degrees C (-34 degrees F).

Certain geographical areas may require lower temperature protection. See the label on your antifreeze container or consult your John Deere dealer to obtain the latest information and recommendations. Never exceed the maximum dilution rate for the coolant you are using. Exceeding the maximum rate will greatly reduce the coolant effectiveness.
