This was in the Dak section, just look for rtkota5point9's posts. He has a digram up as well and apparently the fan is always on.

 

I saw that thread. It's a dandy!!!

I saw on ebay that a 98 and newer Mark VIII fan pulls more CFM than the older ones. Any truth to this? Could just be a ploy, but you never know....

 

I dunno but I Just got everything I need to the tune of $100.00

 

Look what I started! [8D]

So Green, how did you like the clearance and the install? Where are your pictures! LOL

Here are a few helpful links:

I got mine hooked up, using rtkota5point9's method, and yes, it's always on, I let it run sometimes after my truck is off to cool the engine...

total cost for me....

20 for the fan..
6 dollars for the two relays
5 dollars for 45 feet of 10AWG wire

31 dollars.. and averaging about 22.3mpg on the highway... up from 21.1 before e-fan...

4.7L 4WD.

 

Well I went around to a couple auto part stores and got the stuff I needed (a little too much I'm gonna have to go back and get a refund[&:]). The relay I got had all the wiring done already and hadvery good instructions on how to wire the fan up properly and have the a/c kick the high speed on for me, while the low speed is kicked on by the engine temperature through a radiator temp probe. For anyone that is interested and good at wiring here's their instructions. I can't wait until next tues. or wed. I am gonna slap this baby in.

Mean, if you go with the dual relay setup I would recommend to use the low speed setting for your A/C and the high speed for the temp probe. Always use the highest cfm rating when cooling is called for by your D.

Otherwise, if low speed is always on, and the temp probe is used for high speed, that should be okay.

 

Heres a link I found about the fan.

Here one about the CFM (4800!! at 14 volts.)

I've read on a couple site that itpulls 30 amps to run and people recommend a bigger alt. But these are also on different cars. Can our D's handle this power need stock?

 

You won't need to upgrade the alt.

 

I don't know why everyone is fussing over how much air the viper fan pulls in. Think about it...depending on what year they come from, it is designed to cool a 488-505 ci V10. It'll coola V8 with ease. Here's a site with viper fans for cheap: http://www.trademotion.com/partlocat...;siteid=214096
