Hello,

Model: V70 AWD 2006

Symptoms: engine running, radiator fan is always running (on).

Observation: everything look normal. Cooling fluid sensor behave normally: in the dash, we see it raising normally till 12'0 clock and it stay there without moving or even glitching. Heater in the car blow hot air. No check engine or warning message in the dash.

the fan is just running and running...

I went to a mechanic that raise some code: CCM-0063 Damper motor - temperature right internal fault. They clear everything and the fan was back to normal behavior (not running always) But after couple of days, the code probably came back and the fan is now always on again.

I don't know that that mean but for this, the mechanic wanted to replace the thermostat housing with the thermostat and coolant temp sensor. I'm not sure this is the right part to replace. I have the feeling that an internal temperature sensor is faulty (sensor under the hood measuring the temp in the engine area). I'm I right? What does trigger the radiator fan to start?

Hope you can help :)

Thanks

Bruno
