Rick the Spud Posted January 11, 2009 Share Posted January 11, 2009 Hi all when my Disco gets hot the rad fan is not coming in - checked the fuses and they're fine. didn't know if there was some form of thermo switch that makes it come on, or if it was easier to wire in a switch to switch it on manually when it gets hot (usually when the rad gets clogged with mud after a few water splashes!) cheers Quote Link to comment Share on other sites More sharing options...
pw8757 Posted January 11, 2009 Share Posted January 11, 2009 If it is an electric fan there will usually be an electrical thermostat in-line in one of the hoses from the radiator - probably the top one. If it's any help, mine is square on the top and has a cover, under which is an adjustment screw, to change the temperature at which the fans start. Many people fit a cut off switch inside the vehicle, to stop the fans continuing to operate after the vehicle has been left. If you have one of these and have inadvertently switched your fans off, this may be the cause of the problem. You can, of course, insert a switch into the circuit to keep the fans on, but bear in mind that they cool the water in the system by drawing air through the radiator. If this is less efficient because it is full of mud, then switches will not be the cure. Arguably, you could achieve what you are seeking to do by setting the thermostat to come on earlier anyway. Hope this helps............... Quote Link to comment Share on other sites More sharing options...

Rick the Spud Posted January 13, 2009 Author Share Posted January 13, 2009 why isn't it coming on then? what makes it work? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 13, 2009 Share Posted January 13, 2009 The engine drives the fan, normally... If it's been converted to electric then it's anyones guess as to how it has been wired up. This is of course unless you mean the Air Conditioning fans in FRONT of the rad......? (assuming the 200TDi setup has these as well as the V8s...)
