Filling Cooling System

1. IMPORTANT: 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 II coolant is recommended when adding coolant to the cooling system.

   Follow the directions on the container for correct mixture ratio.

   Park machine safely. (See Parking Safely in the SAFETY Section.)
