OPERATION

3-20 / Pierce Pumper

5. Open engine cooler valve.

OPEN the engine cooler valve 

(Figure 3-1)

 to provide more engine cooling when air temperature is above 

80 degrees F, or if engine overheats. Heavy pumping in hot temperatures requires extra engine cooling. 
The engine cooler transfers heat to the pump discharge water through a heat exchanger.
Turn the knob one-quarter turn counterclockwise to the left to OPEN the valve. To CLOSE the valve again, turn 
the knob one-quarter turn clockwise to the right.
Many departments leave this valve fully OPENED during summer and CLOSED during winter.
CLOSE the engine cooler valve for road operation during cold weather for more cab heat. 

6. Observe pump-overheat indicator (optional).

Watch the pump-overheat indicator during pumping operations to make sure that the pump stays cool.
If the overheat indicator light turns ON, add fresh water, recirculate, discharge water, or shut engine OFF to cool 
the pump.

Engine Cooler adds engine heat to the pump water.
Tank water will heat up faster when engine cooler valve is open.
