I'm looking into converting to an E-fan. Is there a complete kit i can buy or do i have to piece something together? How much does this normally run and how much does it improve gas mileage? I know its not much but every little but helps!

 

I converted to an Efan a few months ago. I can't say for sure that it measurably improved my mpg any as I desnorkled the air box and dropped in a K&N filter and added a Magnaflow SS muffler. All these mods were done too close together to say what did what. I also started using nonethanol gas this year. If I were to guess I would say don't expect more than .5 mpg gain at best. I base this off of two vehicles I converted to Efan. Bottom end feels stronger though. What I did was I removed the clutch fan. Measured carefully to the water pump hub to the condensor fan. Pulled the shroud out and laid on the concrete floor. Installed a 18" Permacool fan by bending the feet out almost straight until they kind of friction fitted into the shroud. Got my clearance right and popped four holes in the shroud with a drill and mounted the fan. I used a single Derale fan controller that mounts inside the radiator outlet. Gives a nice factory look and if you have a Duratec you retain your condensor fan for AC operation.

 

I removed my mech fan since my 23ns came with an electric helper fan for when the a/c was engaged so it cost me $10 for a removal tool i still had to hit with a grinder to make fit the duratec. Id like to think the revs drop a little quicker, but cant say ive noticed a difference in throttle response and dont keep track of mpg's. Am i still glad its gone?, absolutely, would i pay 150 to do it ?, maybe not. Everything does add up though and it will definitely do more then a throttle body spacer.

 

Been considering this but not sure any other experiences out there? And a kit would def make this more enticing.

 

A kit kind of takes the fun out of designing it yourself. I went with the 18" Permacool due to high cfm rating, low amps, fits factory shroud and I could retain the factory electric fan for AC.

Some people go with the Taurus fan which is probably even more powerful and draws way more amps. Don't know if our little four cylinders need that amount of cooling. But it can be had for cheap when you go salvage yard. Even aftermarket factory fan would be a good and cheap choice if you need that much cooling. The only reason I didn't use the Taurus fan is the amp draw and needing it to run for the condensor.

When I converted the 2000 F150 I use to own a 3.8L Windstar fan was used. This gave me dual fans with one of them two speed.

 

What many seem to forget is the original reason for converting Rangers over to e-fans.
It was not for gains in mpg's or any 'cool' factor.
It was done for off-road rigs that did deep water crossings . The mechanical fan could / did cause damage when encountering fluid instead of air.
Installing an e-fan enabled the driver to shut off that swerlling dervish that threw water and fish all over the engine compartment.

 

Ken, don't know what difference it makes but the offroad people probably stoled the idea from profession racers!
