On the last few times I have been for a run the fan has remained running for a long time afterwards. Obviously, when the engine is hot I would expect that, but after waiting for a long time and then checking that the temperature has dropped. The fan still continues to run. If I then disconnect it and then reconnect it, it remains off. It just seems that it is not turning off correctly when the temperature drops. Has anyone else had this problem? Do I just to replace the fan thermostat, and if so, does anyone know where to get one and what it needs to be - I assume the come in different temperature ranges? I cannot see the make of fan. The car is a Ford 2 litre powered RH 2B.
