Engine Fan Removal?

Had an idea in my mind, just curious how crazy it is. Would it be reasonable or possible to remove the fan from your motor, keeping the pulley, just removing the fan, and putting in electric fans on your radiator relayed to a switch?
Just figured I'd bring the idea to some others to get some real feedback.

 

Reasonable, I dont know. Possible, yes. What would you be trying to accomplish by going that route? That'll help us define if it's reasonable or not.

 

If you do make sure it comes on with air conditioner compressor

 

Is there something wrong with the OEM fan? If so, why not just fix it (or do you have money to throw away at your truck)?

 

No reason for trying it. Just wondering is it risky? Is it more or less efficient than the stock fan?

 

I did it on my 78 2wd. It wasn't worth it, the electric fan was not as good at cooling as the factory fan then the electric fan failed. I put the factory fan back on. Maybe on a race car that moved at speed most of the time this would be a good idea but not on a street vehicle or 4wd that needs cooling while moving slowly in my experience. I had to turn the heater on full when the truck started to overheat on a hot day in traffic.

 

I did it on my 91. I wouldn't do it again. It did cool very well and looked sharp but was very loud by comparison. Also incurred a very high current draw so that my headlights would dim whenever it kicked on. Didn't see any gain in mpg or power.

 

That's the exact setup I have. Dual Flex a Lite electric fans, controlled by a switch inside the cab. I leave it "on" at all times for obvious reasons as I don't want my truck to overheat, so I think the manual switch idea is dumb (previous owner installed it).

Plus, when I'm off-roading in 4lo for extended periods of time on inclines I start to overheat. E-fans don't do so great at cooling in high RPM/low speed circumstances, they are better for performance applications. Going back to the stock fan clutch is on my list of to-do mods.

 

This too! My e-fans are loud as hell (even though Flex a Lite advertises them as "quieter" than the stock fan clutch ) and my lights dim real low if I so much as lightly feather my clutch, and my power windows slow wayyy down when I work both at the same time. I always wondered why that happened lol, makes sense that the e-fans are drawing all the power. Thanks!

 

Keep the stock fan and clutch. Electric fans would be a step backwards from a reliability standpoint.

 

Ill be the odd one out and say Efan was one of the best power gain mods ive done to my 2rz and Ive done everything short of boost or cams at this point.

Fans are a little louder but doesnt bother me, my truck isnt quiet in any way. I run the Flex-a-lite dual fan set for the specific vehicle not a universal. Couldnt be happier. Granted I do run dual Optimas and the biggest Mean Green alternator made for the 2rz.

Oh and I used to have on an autoswitch but went manual a number of years ago and never have had an issue.
