Electric Fan Conversion?

Did a search in the forums, but couldn't find anything on topic. Has anyone done an electric fan conversion with their HMMWV's? Curious if it would save a little space and clean up the engine bay. Any thoughts?

Short answer, not worth it.

you won't find any electric fans that move anywhere near as much air as the stock fan. Stock fan is in excess of 10k cfm air moved, and most electric are in the 2k cfm range, so you're talking a lot of fans and having to have room for all of them.
I believe it's been said that the stock fan requires about 10hp to operate.

There is one guy that did it and seems to be happy with it, but he separated every single item out in the cooling stack and has electric fans on each system, so 4 or 5 different ones spread out all over the engine compartment.

The most useful fan mod seems to be going to a civilian style viscous type that eliminated the cadillac valve and related system. Draws less power, and keeps the engine at a more steady temp.

I have radiators built for custom application both in the US and China. Both with electric fans.... It would take a heck of a fan to move as many CFM as the stock units. As well as some shrouding work. The complexity of DWF application would be add another wrinkle to an electric unit.. A fan clutch (ala 1980 Chevy truck) would be a simpler solution - but that all depends on the problem your trying to overcome.

Someone on here had done an electric fan swap and use the crown vic fans and was happy with it, I think his fan system was pulling 5,000 CFM, take note, that is 2x less than the hydrualic setup.

We put an “14 electric fan on top of the standard radiator. More or less
a “helper fan” in traffic or off roading. if the gage starts coming up past
205 hit the switch. yes summer in traffic or out in the sand the engine fan
wI’ll cycle but a lot less after the electric install.
