Focus 1.6
The cooling fans come on afeter a few seconds, even when starting from cold. I think it may be the engine temp. sensor. Where can I find it?

Hi, the temp sensor is mounted between the #2 & #3 sparkplugs, it measures the cylinder head temperature not the water temp, it sends it's signal to the engine ecu and it decides when to energise a relay to put the fan's on. If you remove the sensor once removed it cannot be re-used, the new sensor needs to be torqued to 10Nm
