Radiator cooling fans won't shut off

[chitown alex]

Well this is the problem.. This past weekend I drove the Treg for about an hour and got home, parked it in the garage and shut it off. My radiator cooling fans stayed running and did not shut off. Now I know someone else on this site had the same problem a while back so if there is anyone else out there that has some advice I would greatly apprecieate it. I am going to replace what ever sensor or switch my self because I absolutely refuse to take to the dealer, I am just trying to get some info before the fans kill the battery. It's an 04' V6 and this is the very first time that this has happened. BTY, even when I am driving I can hear both fans running @ full blast too, witch has never been normal for my Treg. It actually sounds loud as hell and it's never been that way. Again thank you all in advance.

I had a "Coolant Overheating" message in my MFI ('05 V.
turned out to bad a bad coolant sensor...and turns out there are two in the V8....the fans would run after it all shut off, etc.....sounds like same issue you have

Thanks alot Jim, By any chance do you know where the sensor is? I found the sensor on line for 26$ and I plan on doing the work myself

Check Bentley component locations in the DIY,Technical section by Spockcat, Marty

beats me....car was all back together when I saw it.

I know one required removing the bumper skin and (I believe) the fender liner...it is buried up front somewhere.

Hopefully, the part numbers and a proper service manual as Marty suggested will help you triangulate the right location and not go crazy/waste time.

It is the only warranty issue I have faced in 44k miles of driving....and befuddled the technicians enough that they replaced one, then replaced the ECU, then got it right on the third attempt and replaced the pair. no issues with it since. knock wood.

good luck

Special thanks to Jim and Marty for the quick responses

I had this issue on my 04 v6. It required them removing the engine and was covered under the CPO warranty

[chitown alex]

Well I don't have a warranty anymore so if it requires removing the engine my brother and I are going to be very busy people!! This is the wierd thing now, I disconnected the power to the fans after getting home (so the battery wouldn't drain) and the next day I started the car and I let it run for 10 minutes, then I connected both fans again. When I got to work I shut off the car and the fan shut off . I don't know why but now she's back to normal! Temp. is steady and no warnings.
