Sensor identification

Post by |2aebird » 02 Aug 2013 12:46 pm

I have a sensor in the top radiator hose and also one that is located in the radiator end tank, I figure they are coolant sensor's, however I don't understand why there are two? Do they each serve different purpose's?

Thanks in advance, Dan.

the sensor in the top radiator hose is for the airconditioning
the other one in the end tank of the radiator is not realy a sensor, it's a thermal switch that operates the electric radiator fan

Cool, thanks. Does the electric fan only work with the air on or should it work without the air? I was trying to wire in another e-fan and it doesn't seem to be switching.

Cheers.
