CAUTION: Do not open cap (A) of expansion tank before coolant temperature is below boiling point. First loosen the cap to relieve pressure, then remove cap completely.

John Deere COOL-GARD™ II Premix and Concentrate are maintenance-free coolants for up to 6 years or 6000 hours of operation, provided that the cooling system is topped up using only John Deere COOL-GARD™ II Premix. Test the coolant condition annually with coolant test strips designed for use with John Deere COOL-GARD™ II coolants. If the test strip chart indicates that additive is required, add John Deere COOL-GARD™ II EXTENDER as directed.

1. Open the hood.

2. First unfasten cap (A) and then take it off.

3. Test coolant using TY26605 COOL-GARD™ II 3-way test strips available from your John Deere dealer.

4. NOTE: Follow instructions on back of reader card in test strip pack when testing coolant.

   Add TY26603 COOL-GARD™ II Coolant Extender (available from your John Deere™ dealer) as indicated by the color matrix on reader card in test strip pack. If tank is too full, drain a small amount of coolant from system before the coolant additive is added.

   NOTE: Visually check cap gasket for sealing effectiveness. A properly functioning gasket should have the imprint of the mating surface but no apparent scratches or leak paths.

5. Put cap (A) back on and close the hood.
