Horton fan question

[birdshill123]

My ZHorton Fan is not operating properly. 1988 FC35. When I engage the
A/C the engine cools down. To me this means the sensor is not working.
The fan overide works OK. Where is this sensor located. Can it be
accessed without a rad removal? Is it a Horton part? Bb Part or Cat?
The Horton manual lists both N.O. and N.C. sensors. Which is the
correct one? Good source for the sensors?

Thanks

The sensor is on top of the engine, just behind the alternator. It is
a NC sensor. If memory serves me correctly, it is a 195* sensor, I
found that changing it to a 205* sensor reduces the fan cycling as the
stock sensor has the fan on before the thermostats are fully open.
Better still, relocate the sensor to the bottom of the radiator, ... I
digress.
