• Do not exceed a 50% mixture of coolant and water.
• Aluminum engine blocks and radiators require approved ethylene glycol based antifreeze.

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 5.3 L (1.4 qt.) OOS and 7.0 L (1.9 qt.) Cab.
   
   

3. Install and tighten radiator cap.

4. Remove tank cap (D).

5. Fill recovery tank (A) to the low line (C).

6. Run engine until it reaches operating temperature.

7. Stop engine.

8. Coolant level should be between the FULL line (B) and the LOW line (C).
