ABSTRACT:
A fire truck cooling system allows for precooling of hot water from the vehicle engine prior to receipt of same by the vehicle radiator. The system includes a precooler which is provided with cooling water either from an onboard water tank when the vehicle is racing to a fire or from a fire hydrant when pumping water at the scene of the fire. A control system comprising pressure switches, a shuttle valve, and a directional control valve allows the precooler to operate on tank water and to automatically switch to hydrant water when such is made available by the main fire control water pump of the vehicle.
