Why is regular cleaning of the radiator crucial in a 12N Crawler Tractor?

Regular cleaning of the radiator is crucial because it plays a vital role in preventing overheating and ensuring efficient engine cooling. The radiator is responsible for dissipating heat generated by the engine during operation. Dust, debris, and other contaminants can accumulate on the radiator fins, obstructing airflow and reducing its ability to cool the coolant that circulates through the engine.

When the cooling system doesn't function properly due to a dirty radiator, the engine can overheat, leading to potential damage such as warped cylinder heads or blown gaskets. Maintaining a clean radiator helps to ensure that the tractor operates within the optimal temperature range, thereby promoting better engine performance and longevity.

While factors such as fuel efficiency, engine noise, and appearance are important in overall tractor maintenance, they are not the primary reasons for cleaning the radiator. The primary focus should be on the cooling function, as effective temperature regulation is critical for the tractor's operation and reliability.
