Is that the actouall coolant temp sensor? if not, what is this one used for?
I have a thermo switch sensor out of a eagle talon and I'm pretty sure it's the same thread size.. if that sensor is useless I would like to use this in place of that to run a e-fan.
if not, I'm sure I can tap that sensor into the coolant neck somewhere.

 

It's called the water temp switch. Its contacts close at about 60*F and complete the circuit to the ECU. It's used as a general temp indication for the 3K warmup system, among other things (if coolant temp is below 60*F, the 3K warmup is inhibited)...

Disconnecting at least one connector from this switch will inhibit the 3K warmup, also...

 

ahh, so basically it's the same type of switch I have from the talon.. I dont really want AWS anyways.. I will try to see if it fits! i think the temperature range in where it activates is different in this switch I have. it's what talons use to turn the electric fans on and off.

my one broke yesterday when trying to looseing it when changeing radiator!!
Can i just leave it there....disconnected from the electrical system??

It depends. If your car is similar to the USA cars as far as emissions go, then what I'd is connect both wires together. If you leave it disconnected then the emissions will not work right as far as the acv goes.

All that switch does is make a circuit to ground. One wire comes from the ECU. The other wire goes straight to ground. Once the water temperature gets up to a certain temperature (given by Wayne in a post above), a switch in the sensor is made and now the circuit from the ECU goes straight to ground. If you tie both wires together, you've accomplished the same thing.

Personally I'd just buy another sensor and put it in place.

 

i thought the sensor ontop of the rad is the 60F sensor....if the bottom one is the it..what does the top one do?....mines not connected and it has no ill effects

 

The sensor on top of the rad is the low coolant sensor.
