Electric fans

I’ve got an n14 and the bolts for the fan hub broke off in the top of the block so I’m installing 2 20 inch and 2 14 inch fans on the radiator. Im assuming that will be plenty of air flow and should keep everyone running correctly and I’m hoping it helps with fuel mileage. If anyone has ever done this please let me know how it turned out so I know what to expect l. And yes I am wiring them up properly.

ease-out or drill them out and heli-coil the bolt holes.


My theory/// only a simple guess, based on what is typically seen (the beer is talkin') ...
A large diesel engine can consume up to about 18-22 Horsepower driving the main fan to cool the engine off properly. This is up to about 16,000 watts of work energy, all depends on conditions, engine rpm, and load

A 13.6 volt electric fan that could move as much air as the engine can, would therefore also have to be about 15,000 watts and draw about 1,100 amps of current from the batteries to do it... so the guesstimated answer according to the beer, would be a solid NO!!!>>>

Even if you cut the energy requirements in half.. that is still about 8,000 watts of energy to drive a fan for the engine under load to keep up ... even with only half the capacity.. an electric fan will not keep up if the engine is under full power load for any length of time trying to climb a hill if it were not at least a 500+ amp +12volts fan... and that would require one seriously h#ell of an alternator (700-AMPS+) just to keep it running, engine at full steam up a mountian.. and a whole lot of efficiency losses too.

STOP trying to re-invent the wheel.. FIX THE ISSUE instead!.
