im seriously considering the electric fan swap but im a little concerned about it being electric.. my truck is a pavement princess so im not real worried about the water and elements getting in the connections but whats the chances of it failing on me? i found a writeup on the range station and theres a few good ones on fullsize bronco as well but the ranger station was the most forward.

Ford Ranger/Bronco II electric fan installation

ive heard alot of people say you can expect a good increase in fuel mileage as well as better throttle response. i also like the idea that i can adjust the temperature on it and i can have it wired up to keep on cooling when the engine is off until its completely cooled.

but does anyone on here know of or can think of any other drawbacks to it? reliability seems to be my only concern at the moment.

 

Having it still run after key off might cause battery issues.

I had a dual set from a Taurus. Worked great

 

i was a little bit concerned about the battery issue as well but i failed to mention it.

ive heard of alot of people getting the ford taurus setups but im very bad with engineering things myself. thats why i was looking at the complete kit but after looking they dont make one for the f150, just the ranger. unless the rangers and f150s fan shrouds were the same which i figure their not...

midnite you said your fans worked well? what all did you gain? loose anything?

 

Hardest part is making the brackets to mount the Taurus fans. $20 at the jy for the fans $15 for the temp controller and misc wiring I had kicking around

 

i could deal with mounting brackets but wiring i would be completely lost. i may try and go with a universal dual flex a lite fan.

 

Or the wiring I used a relay to feed power from the batters to the fans. And ran key on power to the thermostatic switch and them to the relay to turn fans on and off

 

is their any downside to having the fans run anytime the key is on?

 

The key on power would go to the temperature switch that would turn the fans on/off as needed. Key on power is just do it doesn't run with key off

 

so you basically wire the key on power to the temperature switch which is wired to the fans?

also with your taurus setup did you find a dual set up or did you put two singles together to make a dual setup?

 

The Taurus had the dual fans.

The power from the temp switch goes to the relay to turn the fans on and off. (use a relay to supply power from battery to fans instead of using the key on power to run the fans.)

 

I run the Mark viii fan. I like the setup..feels like it freed up a little horsepower, fan doesn't run until needed which brings engine to op temp quicker saving a little fuel. Plenty of threads on wiring electric fans...not that difficult. Stay with the markviii or taurus fans as they flow more cfm. Mounting is fairly easy with some quick zipties like the one's used to mount aux trans coolers. Also much easier to work on the front of the motor, change belts, etc. Most every new truck/suv has electric now days so they are reliable. Only thing of note.....may want to upgrade to 130a alternator. Also...I would use adjustable temp switch and a remote toggle. I use two relays, and adjustable imperial themo switch and a manual toggle...also wired to come on auto with A/C.

 

i may try to pick up some taurus fans instead then. any difference between finding a dual setup and using two singles?

 

sheesh does nobody read True Blue Trucks magazine?

A guy just did a write up to do an e-fan swap. He used a 94-00 ford contour or merc mystique v6 dual fan setup.

they are only 3.5" thick overall and he wired up both fans seperately incase one goes out he can still get home off the one. Not to mention with both fans running it is over 4500cfm which is almost more than any after market fan, let alone a lincoln mk viii. He has a detailed schematic for the adjustable thermostat and all. Very easy and fan is like $40 at a JY.

 

thats how mine was wired

 

I was always under the impression to run the fan relays to a constant power source wether the engine is on or off. My wifes car came factory with an e-fan and it still runs when the car is off to cool it down. Once it hits the off temp they shut off. All stock electronics and battery and we have had no problems.
