I have a 2002 disco 2 td5 manual and have been checking out the cooling system well I took of the front grill and found that I have a electric fan fitted to the front of the radiator.its not a kenlow and it looks like a factory fitted option all of the fixings for it are proper welded on brackets and its wired directly from the wiring loom I cant see any info on the fan and have never heard it working so I am not sure if it works.I am going to check to see if the fan motor is working but its probably the thermostat which I have no idea where it is when I bought it it was a one owner and the owner was a company that makes horse boxes so I thought is it possible that they had a factory fan fitted by the main dealer becouse they used it for towing bit of a mystery any ideas !!!!
