I have a Vl Calais with a 308. It used to be an RB30 and has a single electric fan. There is no fan off the water pump. I am trying to tidy up the engine and get it running - is it best to run with the single electric fan, replace the single with a twin electric fan, or forget about these and install a viscous fan off the pump? Any input would be greatly appreciated

ive hear mixed reviews in regards to electric vs clutch fan if you do go for eletric thermo . get a set of ford au thermo's . i know there drain a bit of power to ps if you need a clutch fan ive got a 308 one .
