I couldnt find anything on the fan or radiator except for the main wiring loom for the fan. Unplugging it did turn off the fan ( no power to it) and the car ran fine during normal driving but when sat in traffic it started to steam from the engine bay but the temp guage didnt get any higher so the fan was plugged back in and all was fine again afterwards. I think the car is being sold on as it seems to have to many problems with it. Mainly that it smokes a lot and on checking the MOT history online it shows that it has had problems since 2005 of ''excessive smoke for a non-tubo engine''. It will do for a few weeks untill someone buys it who isnt bothered about a bit of smoke.
