ELectric Fans on a Cummins ?
For $600 or so FLex a lite makes a fan kit for the CUmmins 5.9 Anybody using it? is there a noticable MPG gain running empty? Does it work well enough to cool the truck when loaded?

Haven't checked them in while....but back then they were NOT recommended for big blocks and big diesels
Bet they now have enough HP to pull enough CFM...but that would mean higher electric power from the alternator
Works for cars, but for towing heavy...you have to make sure the whole system is capable...ie the alternator and the protection circuit (fuses, switch, relay, etc) are sized for the higher power
PS...the alternator ratings are for a duty cycle. Meaning a 100 amp @ 40% duty cycle is only good for that 100 amps for 40% of some time period....then the rest of that time???very little current???else damage the alternator
