After using winter agricultural machinery, it's essential to drain the cold water promptly to prevent freezing damage. If you forget to drain the coolant and the engine freezes, follow these steps to address the issue:
First, locate the crack.
1. Place some charcoal at the bottom of the engine compartment and slowly bake it. Avoid direct flame exposure. At the same time, open the hood and pour warm water into the system. Do not use boiling water—start with lukewarm water and gradually increase the temperature. Perform this process by pouring water from above and draining from below until all the ice has melted and drained out through the valve. Once fully thawed, close the valve, fill with hot water, wipe off any dirt, and inspect the area for cracks.
2. The cylinder head and engine block are typically designed to resist freezing. When freezing occurs, the antifreeze plug expands to protect the engine. Therefore, in minor freezing cases, the machine is usually not severely damaged. If cracks do occur, they tend to appear in weaker areas. Once a crack forms, pressure in other parts will drop significantly, reducing the chance of further cracking. So, if the engine freezes, it’s likely only the weakest spots that are affected.
3. If the engine is frozen and cracks are not visible externally, perform an external inspection. Loosen the oil pan drain plug—if water leaks out, drain the oil, remove the oil pan, and carefully check for the source of the leak.
Second, take appropriate repair measures.
1. Once a crack is identified, repair it using welding, sealing, or metal plating depending on the severity.
2. If the radiator is leaking and the damage is minor, you can block both ends of the water pipe core and continue using it. However, if there are multiple cracks, it’s best to weld the damaged areas before putting the machine back into service.
It's important to act quickly when freezing occurs to avoid costly repairs. Always make sure to properly winterize your equipment after each use. Regular maintenance and proper drainage can save you time, money, and potential engine failure in the long run.
