Fans??
Just drove for no more than 5 mins and less than a mile and my engine didn't even touch 70 degreess. When I got home the fans were on after I switched the igniton off and 5 mins later they are still on. I've restartedd the engine and unplugged the sensor a few times to no avail. Surley they shouldnt come on?

Re: Fans??
you might be lucky enough to have working A/C and I have heard from far too many friends back in the UK that its a bit warm there right now, maybe its something to do with this??

Re: Fans??
Fans running full tilt with the sensor unplugged is normal, perhaps the sensor's gone up the swannie.

Re: Fans??
As Steve says, it's most likely the case that your car has multiple coolant temperature sensors (the V6 has three - one for the ECU, dash gauge and dash gauge overheating light!) and your ECU one has gone south. About £30 from the dealers or £20 from ECP/GSF if they have one. You'll also be looking at a coolant top-up and bleed...
Another cause could be a stuck relay, but that shouldn't happen at full speed unless the car's had reason to engage full pelt mode, so it's unlikely

<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang

Re: Fans??
It was just fan 1 that was on as I found out. I think the brown sensor is the ECU one iirc

Re: Fans??
Just the one? Damn, where's my Haynes? I can't remember which way round it is but mjb could be there with the stuck relay.

Re: Fans??
Just the one then I'd definitely say stuck relay if you know the other fan works

Re: Fans??
Right both fans seem to come under the fan 1 fuse? There both on all the time.

Re: Fans??
I've taken the car for a drive with the fuses out and it seems to have sorted it out?
