Missing Thermoswitch Wire Into Radiator

[ak_stylez]

as per topic title, I have come to realise that my car is missing this temperature switch which screws into the driver side of the radiator (next to the lower radiator hose).

I've always had a dangling electric wire with green plug coming from next to the driver side headlight, I guess this plugs into the temperature sensor?

what is the purpose of this sensor? where can I get a replacement (if indeed a replacement is recommended)

thanks in advance for any help

that sensor just switches the thermo fan on for the air con when it hits a certain temp. say your sitting in traffic on a hot day and you have the aircon on, the themo fan will turn on.
