Which component can help control excessive engine temperatures during pumper operations?

The auxiliary cooler is specifically designed to help manage engine temperatures, particularly during demanding operations such as those performed by pumpers. This component provides additional cooling capacity, ensuring that the engine operates within optimal temperature ranges even when it is under heavy load.

By facilitating better heat dissipation, an auxiliary cooler helps prevent overheating, which can lead to engine damage or reduced performance. This is especially important in emergency situations where engine performance and reliability are critical. It effectively complements the existing cooling system, enhancing its efficiency during high-stress operations.

While other components like a tank to fill valve, radiator cooler, and immersion bypass may play roles in the cooling system, they do not directly address the management of excessive heat during intensive operations as effectively as the auxiliary cooler does.
