I have removed the standard engine driven fan on both my 308s. I run the same set up in both with no dramas. Holden 3 core radiator with single 16" thermo fan on engine side, davies craig termo control unit to turn fans on when nearing 3/4 on the gauge. Being only one fan motor, I don't have any alternator dramas. Been running this for over 20 years in one car now.
