Thats not bizarre!

HERES BIZARRE - 35 years ago, I was a firefighter driving a 1957 Maxim pumper - one day, on a run, the temperature gauge went way past hot, All the way around to the stop post at zero!

We saw no signs of over heating and found that the cooling system was COMPLETELY full, Pressure was pushing the gauge around.

It seems that the radiator fill valve on the pump was leaking and had liquid filled the cooling system.

In case of a failure, pumpers are equipped with a cooler valve that sends pump water to a heat exchanger to cool the engine, if that does not cool the engine, you can open the radiator fill valve and put pump water directly into the cooling system in order to keep supplying to the firefighters with pump water.
