Service Cooling System Safely
Recommended Engine Coolant
The engine cooling system is filled to provide year-round protection against corrosion and cylinder liner pitting, and winter freeze protection to -37 degrees C (-34 degrees F). If protection at lower temperatures is required, consult your John Deere dealer for recommendations.
The following coolants are preferred:
• John Deere COOL-GARD II™ Premix
• John Deere COOL-GARD PG Premix
John Deere COOL-GARD II Premix and John Deere COOL-GARD Premix are available in a concentration of 50% propylene glycol.
John Deere COOL-GARD PG Premix is available in a concentration of 55% propylene glycol.
Additional recommended coolants:
• John Deere COOL-GARD II Concentrate in a 40% to 60% mixture of concentrate with water.
• John Deere COOL-GARD Concentrate in a 40% to 60% mixture of concentrate with water.
If the recommended coolants are unavailable, use an ethylene glycol or propylene glycol base coolant that meets the following specification:
• ASTM D3306 prediluted (50%) coolant.
• ASTM D3306 coolant concentrate in a 40% to 60% mixture of concentrate with water.
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.
Water Quality
• Water quality is important to the performance of the cooling system. Distilled, deionized, or demineralized water is recommended with ethylene glycol base engine coolant concentrate.
