I have a 92 Mercury/temp topaz, 2.3 ltr engine (4cyl).
The fan does not kick on, but if I pull the wire off the tempature sensor located next to the thermostat, it turns on ONLY when the car is up to temp.

Today i bought 2 parts from autozone.
Temp sensor Duralast part SU201
and a temp switch, Duralas TU25

I know where the temp sensor goes, but cannot find a diagram of where the temp switch goes, nor can I locate it anywhere on the engine.

Does anyone know where it would be located at? the thing is a little bit smaller than a bic lighter.

Thanks.
