Coolant Drain and Flush Procedure<\/h2>\n

1. Park and Prepare<\/h3>\n
    \n
  • Park the tractor on a level surface.<\/li>\n
  • Turn off the engine.<\/li>\n
  • Remove the key from the ignition switch.<\/li>\n<\/ul>\n

    \"\"<\/h3>\n

    2. Release Cooling System Pressure<\/h3>\n
      \n
    • Once the engine has fully cooled, carefully loosen the deaeration tank cap (1) to the first notch to release system pressure.<\/li>\n<\/ul>\n

      NOTICE:
      \nThe cooling system pressure cap includes a control valve that functions as a safety relief valve, maintaining system pressure.
      \nNever run the engine without the pressure cap in place \u2014 doing so can cause system damage.<\/p><\/blockquote>\n

      \"\"<\/h3>\n

      3. Drain the Coolant<\/h3>\n
        \n
      • Open the radiator drain valve (2).<\/li>\n
      • Collect the drained coolant in a suitable container for safe disposal.<\/li>\n<\/ul>\n

        \"\"<\/h3>\n

        4. Add Radiator Cleaner<\/h3>\n
          \n
        • Fully remove the deaeration tank cap (1).<\/li>\n
        • Pour in a commercial-grade radiator cleaner.<\/li>\n
        • Fill the system with clean water.<\/li>\n<\/ul>\n

          NOTICE:
          \nAlways follow the product instructions and ensure the cleaner is compatible with aluminum radiators.<\/p><\/blockquote>\n

          5. Flush the System<\/h3>\n
            \n
          • Drain out the radiator cleaner solution.<\/li>\n
          • Flush the entire system thoroughly with clean water, following the cleaner manufacturer\u2019s directions.<\/li>\n<\/ul>\n

            6. Inspect Cooling System Components<\/h3>\n
              \n
            • Check all hoses, fittings, and heater hoses for:\n
                \n
              • Cracks or wear<\/li>\n
              • Loose connections<\/li>\n
              • Signs of leaks<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                \"\"<\/h3>\n

                7. Refill with Coolant<\/h3>\n
                  \n
                • Fill the cooling system with a 50\/50 mixture of:\n
                    \n
                  • AMBRA ACTIFULL\u2122 OT EXTENDED LIFE COOLANT or
                    \nAKCELA ACTIFULL\u2122 OT EXTENDED LIFE COOLANT
                    \nand distilled water.<\/li>\n<\/ul>\n<\/li>\n
                  • Fill to the fill neck of the deaeration tank.<\/li>\n<\/ul>\n

                    8. Run Engine and Recheck Coolant Level<\/h3>\n
                      \n
                    • Start the engine and let it run at low idle (1\u20132 minutes).<\/li>\n
                    • Shut off the engine.<\/li>\n
                    • Check the coolant level in the deaeration tank.<\/li>\n
                    • If needed, top up to the fill neck and reinstall the pressure cap securely.<\/li>\n<\/ul>\n

                      \"\"<\/h3>\n

                      9. Fill Coolant Recovery Reservoir<\/h3>\n
                        \n
                      • Fill the recovery reservoir (3) with the coolant mixture up to the full line.<\/li>\n
                      • Reinstall the reservoir cap.<\/li>\n<\/ul>\n

                        10. Bring Engine to Operating Temperature<\/h3>\n
                          \n
                        • Start the engine again.<\/li>\n
                        • Run it at 1200\u20131500 RPM until the coolant reaches normal operating temperature.<\/li>\n<\/ul>\n

                          11. Inspect for Leaks<\/h3>\n
                            \n
                          • Shut off the engine.<\/li>\n
                          • Allow the system to cool completely.<\/li>\n
                          • Carefully inspect the cooling system for any leaks.<\/li>\n<\/ul>\n

                            12. Final Coolant Check<\/h3>\n
                              \n
                            • Once the engine is cold, check the coolant level at the recovery reservoir only.<\/li>\n
                            • Do not remove the deaeration tank cap at this point.<\/li>\n
                            • If necessary, top off the recovery reservoir with the coolant mixture.<\/li>\n<\/ul>\n

                              \"\"<\/p>\n
