Datsunman Posted August 6, 2006 Share Posted August 6, 2006 When I'm driving a great deal of the time I can hear the viscous fan whirring away and every now and then I hear the sound die away but after a minute or so it'll be back...usually after slowing to a junction or stopping. It seems to me that the engine is driving the fan a great deal more than it should as the engine (TD27T) temperature is stable and it makes no difference what the ambient temperature outside is. If I turn the fan when the engine is stationary and cold, it turns on the coupling but there's quite a bit of resistance so I'm thinking there's something up with it. Most others I have ever had spin freely. It looks to me like the viscous coupling cannot be removed from the water pump... it this the case? Would a thermo electric fan be better anyway? I'm thinking of maybe pulling the fan off of the viscous coupling and sliding a thermo fan in there instead. Is this any better than the engine driven fan or should I just try to locate a functional viscous coupling? Cheers, Ed Link to comment Share on other sites More sharing options...
Extreme90path Posted August 7, 2006 Share Posted August 7, 2006 I like Termo Electric fans. No pull off of engine power that way. Link to comment Share on other sites More sharing options...
88pathoffroad Posted August 7, 2006 Share Posted August 7, 2006 An electric fan will work well, but the belt-driven fan will cool better, particularly at lower speeds. You choose. Link to comment Share on other sites More sharing options...
