What is the purpose of the auxiliary cooling device on an apparatus pump?

Explanation:
During pumping, the engine works harder and generates more heat. The auxiliary cooling device provides an extra cooling path to circulate coolant and remove that heat while the pump is engaged. This keeps the engine from overheating, helps maintain pump performance, and protects engine components. The other options aren’t about cooling the engine during pumping, so they don’t fit the device’s purpose.
