I am planning to install a 6.5 diesel into a Jeep TJ Wrangler. I need all the front to back clearance I can get. Now if I were to eliminate the fan clutch all together and bolt the fan directly to the pulley (I need to add 1/2" spacer to clear the drive belt), I should be able to save about 1-1/2".
Prior to the 80's all fans were direct coupled. Does anyone know how this would impact fuel milage since I think this is why they were created in the first place? Any other possible implications? I plan on using a 21" Duramax fan.
Any help would be appreciated, Thanks.
