I've read posts that some here have used E-fans from a Taurus or a Crown Vic.
Is there certain year/years for these that I should look for?
Thanks in advance.

 

i wouldnt put some old taurus used e fans on a nice 2006 King ranch like yours...i wouldnt even do it on my 97 ....Not at all the answer you wanted ...just my opinion

 

Actually Taurus fans are pretty nice, well built. I have a set and the harness, just don't have the surround or controllers yet. I had a chance to get all of it, but passed, - shouldn't have because the Taurus surround is needed. Nothing wrong with it and that would be about a noticeable 15 hp an upgrade.

Most go with Mark VIII set ups and big CFM's, but that's a single and a big amp draw starting out. I'd rather have the dual set up myself, personally. Ford efans are all nice IMO.

The older clutch fans last forever, but they do tax the engine, - more so with age.

 

i went with a mark VIII fan from the junk yard off a mark 8 30 bucks. but Jbrew is right these fans pull mad amps on start up but they cool the engine like no 2 morro.

my RPM at idle goes from 500 to 350rpm when i flick the switch then it jumps to 700 then trys to get back to 500 the fan puts alot of stress on the Alt. but i like it cools the truck down nice

 

Thanks for the info guys.
A buddy of mine works for a wrecker service and he saw me looking at fans so he offered to find me one.
I figureed free is always better then having to pay for one.

We plan on moving down to the SW in a few years so maybe the Mark VIII would be the best bet, but I will ask him to keep his eyes open for what comes thru.

I was thinking bout underdrive pulleys also, if I had the pulleys would the Mark VIII still draw that many amps?

 

if you hooked up the low speed and high speed setting it wouldnt be to bad but i think if you hook it up just high speed like i have it draws somthing crazy like 10-15 amps on start up.

not sure how much pulleys would help.

mine at idle goes from 600rpm dips to about 300-400 then shoots up to 700 then idles back to about 500 when i flip the switch my truck is not happy when i turn it on.

 

Ok, if I undersand this correct you turn it on.?
Isn't the fan called for by the controller or does it just depend on how you want to install?

Also is there a specific year to be looking for in these fans?
Thanks again for the help!

 

i have a simple switch i do not trust the controllers ive heard to many storys of them failing.

i have a a 12Volt wire from the batt. with an inline 40amp fuse then the wire comes into the truck to a switch i have on the dash then from the switch to the E-fan and it is grounded to the rad. mount.

i have an aftermarket temp gauge when that gauge gets above 200* i flip on my fan.

 

I'm currently in the process of collecting parts/info for putting an e-fan in my '99. I've read a bunch of threads on the subject, and this is a summary of what I've learned ...

The factory mechanical fan is very reliable ... if your not going to match this reliability w/ your e-fan mod, then don't bother w/ the mod. A failed fan will leave you stranded on the side of the road watching the Chevy's drive by.

The Mark VIII fan ('93-'98) is a good fan which moves a lot of air. It also takes a lot of power to run (you don't get something for nothing). Because it takes a lot of power, you're best off using a variable speed controller which will start the fan slow (avoiding the large start up power draw), and vary the fan speed based on the cooling needs. By only running the fan at a speed necessary to cool, you put less load on your alternator and thus less load on your motor, potentially increasing your mileage. You might pay 3 times as much for the controller than you do for the fan.

You're best off mounting your fan in some sort of shroud which covers the entire radiator so the fan pulls air through the entire radiator (like the factory setup does). My plan is to combine the stock shroud w/ the Mark VIII shroud to accomplish this.

Your wiring job must be top notch ... proper sized wires, good connections, proper fusing.

Ebay fans and cheap on/off controllers will cool your truck fine in most situations ... they may not be adequate in extreme situations, and they may not match the reliability of the factory mechanical fan.

Some people claim 1-2 mpg increase ... almost all speak of a more responsive motor, a quieter truck, and colder AC at low engine/truck speeds.

I'm moving forward w/ the mod, but I'm still not 100% convinced it's better than the factory fan, in terms of reliability (but hey, I like to tinker ... ).

 

I don't care what YOU do, Shifty, but I would NEVER run a high draw line into the cab and directly control it with a switch. This is a fire hazard. Use a relay.

 

So, another write up maybe ?

Your write ups are going to save me a bunch of time.

 

I'll most likely do a write up at some point. How soon, I can't say ... momma's starting to get pissed I'm not working on her house projects.

 

Ditto DO NOT wire without controller or relay(s)!!!!!!!!!!!!!!

 

Yea, you have to keep momma happy, but you might want to save those write ups for Better Homes and Gardens

 

Also from what I understand the mark VIII can spike up to 115A on startup if you don't have a controller that has a soft start feature like the DCcontrol. I am not sure if the spal unit is soft start or not, but from everything I am reading people running them of just relays are using 120A relays and 40-50 amp fuses behind the relays.
