Service Cooling System Safely
Recommended Engine Coolant
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:
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.
Servicing Cooling System
Checking Coolant Level
1. Check coolant in coolant expansion tank (A) when engine is at operating temperature.
• Coolant expansion tank should be half full at engine operating temperature.
• Once radiator is full, add coolant mixture to expansion tank until 1/3 full.
