  A - Radiator Cap

  B - Coolant Recovery Tank

  C - Full Cold Line

  D - Coolant Recovery Tank Cap

  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 base coolant.

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. Remove radiator cap (A).

3. Fill cooling system to specification.

4. Install and tighten radiator cap.

5. Run engine until it reaches operating temperature.

6. Stop engine.

7. Allow engine to cool. (Some coolant may be drawn into the radiator from the recovery tank during cool down.)

8. Check recovery tank (B) coolant level.

   • After engine cools, coolant level should be at the FULL COLD line (C) on the recovery tank.
   
   

9. Remove cap (D) from recovery tank to add coolant if necessary.

10. Install right side panel.

11. Lower hood.
