Flush Cooling System and Replace Thermostat

IMPORTANT: Service interval can be extended to five years or 4500 hours thereafter when tractor coolant has been checked annually and serviced with pre-diluted John Deere COOL-GARD™ II.

Have your John Deere dealer drain old coolant, flush the entire system, install new thermostat and fill with clean antifreeze solution after first three years and after every 3000 hours of operation.
