Radiator Fan Sensor

Hi Folks

2004 Laguna 2 Extreme - 1800 petrol.

Radiator fan has started to play up and wont switch off when I stop engine. I have swapped relays over and this hasnt shown itself to be problem so I am assuming its the sensor. Big problem is where on earth is it located on the car.

Be grateful for a shove in the right direction.

Many thanks

On the Lag II the radiator fan is controlled by the ECU which monitors engine temperature via the engine coolant temp sensors.
Also remember the fan also responds to the air-con system.

I take it you replaced the resistor/relay located on the fan shroud.
