Filling Cooling System

IMPORTANT: 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.

NOTE: John Deere COOL-GARD coolant is recommended when adding new coolant to the cooling system.

Follow the directions on the container for correct mixture ratio.

1. Allow radiator to cool.

2. Fill cooling system.

   • Cooling system capacity is 3.7 L (3.9 qt).
   
   

3. Install and tighten radiator cap.

4. Run engine until it reaches operating temperature.

5. Stop engine.

6. Check recovery tank coolant level and add coolant if necessary

7. Lower hood.
