      2004 s80 loud fan

      Hi everyone Iím new here. I recently bought an 04 s80 with 137,000 miles and it has been really great. The only issue with the car is upon start up the radiator fan (I think itís the radiator fan) starts right up. Iíve done some research and others were saying that the thermostat is bad and the sensor is too. If that is true can I buy the thermostat valve or the whole housing?

      Have you looked under the hood to confirm that the fan is going into instant high speed mode? I've rarely, if ever, heard my 2.5t kick it's fan into high-speed mode.

      I posted a similar problem I've been having on the S60 forum (thought it's an S80).... What I've been doing is disconnecting the negative battery cable and touching it to the positive to clear the ECU. It then behaves normally ...... for a while. Give it a try and let me know what you find.
