Peugeot 307 radiator fan

The Peugeot 307 radiator fan turns on when I turn off the engine and runs for about 10min.It starts at a lower speed and then at a higher speed, the engine temperature is around 70 degrees c.

I assume that your model has a fan switch mounted in the top of the radiator. That could be fairly normal operation, or it could be that the switch has lost its calibration and is a bit sensitive.

You would need to measure the temperature at the switch (with an infra-red thermometer or similar) to work out exactly what is happening.

For tomorrow, I plan to clean the egr valve and to clean the drainage channels under the windshield, so I will look at what could be the cause of the incorrect operation of the fan.
