Don’t worry about the 13.5V business. The system will be around there if the generator is charging anyway. Instead add up the total amps you are drawing, the radiator fan, wipers, lights, heater fan, radio etc… Do you have AC? That clutch will draw some too. If you have the original generator you have about 30A available, so you don’t want all that to add up to more than 30A. Of course, if it’s raining, you won’t need the rad fan…
As far as what fan to get, all I can add to the research already done is that the 750 CFM fan I had seemed to do nothing helpful for the cooling. More, maybe double the CFM are needed.
