The End All, Be All FC3S Electric Fan?
Howdy folks,
A few weeks ago I had a severely leaking water pump on my S4 black 'vert. I finally took the time to swap it out and discovered that the upper end tank on my factory radiator was split length wise and allowing water to seep out. So, I went and got a replacement factory radiator but while I had the car apart I decided to ditch the stock clutch fan/shroud and go to an electric. The next weekend my wife and I hit the local parts yard for a fan. I'd forgotten to take my tape measure so I was basically taking a guess at what kind of parts yard fan to grab.
I wound up running across a few Mercury Villagers. The fan w/ square shroud looked great so I took a few minutes to remove it off the radiator and take it home. I trimmed the plastic mounting tabs off, shaved 1/4 of the underside plastic off to make it more flush, drilled a few holes for some plastic mounting rods, then w/ some weather stripping I mounted it to the radiator. It was a perfect fit!
It's an 18" fan enclosed in a 23" x 19" shroud which is the exact dimensions of the factory radiator and Koyo radiator cores. With a bit of trimming, it fits snugly in-between the radiator's two factory fan shroud mounting tabs. The fan is also extremely powerful. I'd say it's moreso than the Pontiac Fiero fan I grabbed back in 2001 for my Turbo II. It's also a better fit.
I've got it wired up to switched +12V power (relayed and fused) on its "hi-power" lead so it's on when the key is in the ignition. I'd prefer to use a thermostat but since this car is still stock I'll just stay with this setup for a while. With the A/C on full blast and at its coldest setting, and in traffic, the factory temp gauge will not budge about 1/4 and normally stays around 1/5th the way up. Pretty impressive!
Here's the link to the pictures of the installation up on my site. For those considering an e-fan, I would definitely look at this one. It's from the Mercury Villager/Ford Quest from the late 90's.

Yep it works! I'm real happy with it! Have already installed another one on a Koyo rad on an FC. Doing one again tonight on a bridgeported T2 w/ a Koyo rad.

This one I'm fusing at 30A but I've got no idea how much amperage it draws. It's own wiring from the factory is 12AWG so I figure it's at least 20A.

While I'm thinkin' about it Hyperterk, I still run the old S4 alternator on my black vert. I've never changed it. With the fan on, using the factory gauge of course, it still shows in the 12V's when idling and driving around. One thing I did do however to prevent an over-saturation of the electrical system (with radio and lights on, etc) was kick the idle up to about 1000rpm.

Right on.
Installing one for a Koyo radiator right now. Will get some pictures of the shroud modified and fitted to the rad and will post 'em up.

Looks good Brian. I am currently using a Ford Mark VIII fan-it is also 18". My fan is a Series II which means the car had a PWM controller and only one speed-HIGH! I miss my 2-speed Taurus action. This might be a good alternative, but what I really need to do is go PWM.
One question: Why does everyone leave the mounting fan studs in the waterpump pulley when they go Efan? I pulled mine out and it looks much cleaner.
