Hello, My Viscus Coupler took a dump on my '94 Range Rover. I wanted to switch over to an electric fan. Can you tell me if anyone has done this and also the size I would need as well as the air flow it would get. Thank you, | ||

I'm not sure why you just don't replace the VC and fan. What would be the advantage of going electric? | ||

The advantage of electric is that it is switchable and doesn't drain power from the engine . You can wire it so that it can be manually turned off for water crossings . They are common in the UK and Aus , I believe that you would find better conversions from the Aussie crowd due to climates .The Brit ones are ok for colder weather . Check the rangie.net . Ed. P.S. I am blatantly spewing info for which I have only read about. I have not changed my VC fan for electric . I have however , changed my water pump . | ||

Range Rovers already have electric fans. Both are needed in hot climates. I suggest you change the coupling and make sure your existing electric fans work properly. | ||

John, I know that repairing /restoring foreign + exotic cars is what you do for a living , but your suggestions always seem to be to keep trucks stock. Why would a VC operated fan be better than an electric fan ,if both have the same capacity to cool the engine ? I am considering this for my RR also , rather than have a stock fan come apart and shred hoses . Wouldn't this be an upgrade of one of the weaker links ? Thanks, Ed | ||

Hi Ed, The times I recommend stock are the times I believe it to be the best answer for most drivers. In this case that's my opinion. In other areas, like suspension, I seldom recommend stock. Please don't think I make my recommendations blindly in this regard - I don't. Your proposal is not an upgrade because you already have both. A stock Range Rover has an engine driven fan backed up by one or two good size electric fans. All three are needed in 100 degree weather. Under most conditions the engine driven fan is freewheeling. When the AC is on the electric fans are the primary fan source. The engine fan clutches in only at high underhood temps. In addition, the electric fans step to a higher speed at high temps. A truck with both electric and mechanical fans can survive under most conditions with the failure of either one. Your proposal would not provide additional cooling, and would make you much more vulnerable. The flaw in your thinking is your "equal capacity" phrase. The fans don't have equal capacity. The engine driven fan, fully locked on a very hot motor, can deliver near ten horsepower of cooling air flow. Electric fans, even though they are more efficient by virtue of their tight fit to the radiator, cannot approach this volume of air movement becuase the truck's electrical system can't support motors that big. Electric fans work 90% of the time, but in the extreme you need both. |
