How Do I Drain, Flush and Refill My Yanmar Tractor Cooling System?

We want to help you drain, flush, and refill your Yanmar tractor cooling system.





If you do not feel that you understand these steps, or can perform them safely, consult your tractor dealer, owner’s manual, or local mechanic.


Time to get started.






SCALD HAZARD:

  • Never remove the radiator cap if the engine is hot. Steam and hot engine coolant will spurt out and seriously burn you. Allow the engine to cool down before you attempt to remove the radiator cap.

  • Tighten the radiator cap securely after you check the radiator. Steam can spurt out during engine operation if the cap is loose.

  • Always check the level of the engine coolant by observing the reserve tank.

  • Failure to comply will result in death or serious injury.


BURN HAZARD:

  • Wait until the engine cools before you drain the engine coolant. Hot engine coolant may splash and burn you.

  • Failure to comply could result in death or serious injury.


COOLANT HAZARD:


Wear eye protection and rubber gloves when you handle a long life or extended life engine coolant. If contact with the eyes or skin should occur, flush the eyes and wash immediately with clean water.


Failure to comply may result in minor or moderate injury.


ENVIRONMENT:

  • Follow the guidelines of the EPA or other governmental agencies for the proper disposal of hazardous materials such as engine oil, diesel fuel, and engine coolant.
