Thermoswitch - fan or temperature dial?

23-05-09, 22:12

I have just replaced the upper radiator hose on my 1994 2.4d T4 due to leaky coolant. I have also replaced the junction where it enters the engine block.

I would be very grateful if someone could tell me the function of the blue thermoswitch (if thats what it is!) with four wires coming out of it at that junction box. Is it to start the fans or to go to the temp dial in the dash or neither?

Any help on this would be very much appreciated, as i'm not sure i've re-wired it correctly.
