JST Posted September 8, 2005 Share Posted September 8, 2005 apparently theres a sensor on the block that tells the fan when to work. the fan looks like a viscous unit and is belt driven. so hows that work then???? Quote Link to comment Share on other sites More sharing options...
Les Brock Posted September 8, 2005 Share Posted September 8, 2005 James, I would have thought in the same way as a air con pump, when the stat sensors the fan need to run, it sends power to the electomagnetic clutch (glorified solonoid), which energises pulls in the clutch and drives the fan Same principle (well almost) as your ARB but with electrikery !

simonr Posted September 8, 2005 Share Posted September 8, 2005 As Les says - Exactly the same as an Air-Con pump. There are two plates, one attached to the fan and the other to the pulley. There is an electromagnet near one plate. When switched on, it magnetises the first plate which attracts the second plate sticking them together and transferring the drive. It's quite an apealing idea - you can have the best of both worlds - having something reliable, that you can switch off if you need.

JST Posted September 8, 2005 Author Share Posted September 8, 2005 something learn'd every day - thank you Si and Les so if they fail its likely to be the sender? Quote Link to comment Share on other sites More sharing options...
Les Brock Posted September 8, 2005 Share Posted September 8, 2005 so if they fail its likely to be the sender? No it could just as likely be the electromagnetic clutch failing, it is after all a type of solonoid ! if the coil goes open circuit, you will get no magnatism, the second plate will not be drawn in and therefore no drive to the fan blades....

02GF74 Posted September 8, 2005 Share Posted September 8, 2005 aren't they fitted to Mercs - G-Wagen? what chance of being able to make one fit to a p6 water pump end? I like the idea of have a big suction fan behind the radiator. Quote Link to comment Share on other sites More sharing options...
