One is mounted to the engine block (I assume this is the one for the
gauge)

The other is mounted in the coolant reservoir tank. ( I assume this is the
one for the aux. fan to turn on)

Am I correct?
If not what is the function of the one mounted in the coolant reservoir
tank?


Probably to see if your Koi are comfortable ?
