Fan conversion variation

Unnamed · Jun 4, 2007

Ok, so there's been lots of people doing an electric conversion of the clutch fan on the Gen 1's.

Though I've been thinking of a variation on this theme? what about swapping the clutch fan for the newer plastic fans on the 4.7L? Or even a 3.7L's fan which I believe is smaller than the 4.7. Thoughts? I know it won't be as much of a gain as the electrical fan, not that the whole conversion is much of a gain to begin with but whatever.

I wonder how it'd fit in the Gen 1 Shroud

I don't know but given the limited expenditures for unnecessary automotive changes, they probably used actual fans to make the molds for the plastic molding machines.

J/K I kinda doubt that they changed the design much if at all from the metallic ones. Maybe more blades?

It defineteely has more blades from what I see in the pic
I bet the dRag coefficient has changed as well

they definitely changed the pitch. The metallic ones look much flatter.

I want to change to an electric fan. anyone has done a how to on this for a first gen? removing the old fan clutch assemby and which is the best electric to use. I see that there are no factory fit OEM type radiators and fans for the 4.7.

thanks for your time,

Try searching using the search button above. There's a lot of information here and even more on a wider variety of options on D-D.

I just went out and looked at the fan on mine. It looks like the plastic ones have longer blades. Maybe 1-2"?

FSTDANGO3 · Jun 4, 2007

Seems like a real different design

If the radiators are of a similar size couldn't you just drop in the newer shroud with the fan?

I looked at the mitchell manual, says that you need special tools from snap on to remove that clutch? 36mm spanner wrench?

FSTDANGO3 · Jun 4, 2007

Special Tools? :?
I used a large adjustable wrench and a quick shot from a dead blow hammer.
Spun right off!

Great Awesome. I wish griffin made a bolt in for the 4.7L
any else have any aftermarket tranny cooler?

FSTDANGO3 · Jun 4, 2007

I'm sure given ample time you could design a 1 off custom.

B&M make a universal cooler for the auto tranny crowds. One model even has it's own fan, so that it can be mounted anywhere.
