Fan Clutch vs Electric Fan
#29
I can see both sides of this argument. i work at a shop that sees multiple different setups daily! now it is more effective on smaller engines! the 4 cylinder will have to work significantly harder to turn that fan than a v6 thats just reality. Now ive seen electric fans fail and the motors end up needing heads. But at the same time rangers commonly get seized clutches and not many people notice cause the fan is often loud now if you run this for too long it will tear up the water pump! there is a temp sensor obviously hence the guage on the dash but the location of the sensor by the time the gauge goes up it may be too late! ive done two head jobs in the past month because of that! so ultimately its your decision but do it quick to avoid serious money!

Hi Nate, I know it's been a while since you posted this. I just got an electric fan kit for my 05 Ranger (3.0, 5 speed manual). The thing I am concerned about going forward to install is, the wiring. Not sure if I run the wires in to the interior fuse panel, or can I use the distribution box in the engine bay? Any thoughts on this would be helpful!

I installed an 18" Perma-Cool fan in my 06 three of years ago. With bending the tabs of the fan slightly I bolted it into the original factory shroud and was able to keep the factory A.C. condenser fan in place. Honestly I don't know if I have heard it come on once yet. But I do live in the sticks and so my truck sees mostly highway/country miles. Almost all the new half ton trucks come with am electric fan now.

Ive been running one for a few weeks. 1993 topaz v6 fan. high is on temp, low on ac. wires myself. ive gone from 450 per tank to over 500. also my ac blows colder, i get heat in half the time, and the trucks acceleration got better. also, you save the waterpump bearings, and the engine idles smoother because its not spinning an unbalanced fan. my MPG went fron 17-18 in the city, to 22 mpg.
if you say they are a waste, you have never seen the difference for yourself. aks the people that have one, not the guys who read about them and form their own opinnions! total cost was $100 with fan and relays. my topaz fan only draws 15 amps.
and considering my tailgate light cost the same, i say thats not a bad upgrade.

E-fans do have advantages, but in order to optimize them there are important features like adjustable temp sensors and high speed cutoffs (when air is turning the fan on the highway) that you must have. That requires a smart controller and those cost $$$. You are looking at about $300 to do it right and you will never be able to recover that cost from fuel savings.
Now if you just want one, try and look for one from a t-bird/cougar/mark8 at the junkyard. You can find basic wiring diagrams on google and do it all for probably $50. But realize that it will be running often when it doesn't need to be and your alternator is already operating near its maximum.

Why would it be running often when it doesn't need too? On mine I still have the factory A.C. fan. Willing to bet it doesn't cut off at any speed unless you cut the A.C. off. Installed a separate controller for temperature. It only runs when it gets hot enough to trip the temperature sensor. I honestly don't think the fan has came on more than twice in 3 years. I have a 5 speed manual, 2.3L and can get over 500 miles on every tank. Though I usually fill up at half a tank. But, that is due to living in the sticks. My last 4 tank average was just over 30 mpg. Before I installed the Perma-Cool my multi tank averages were close to 29 mpg. My numbers show about 1 1/4 mpg gain pre fan installation. If I lived in the city I am pretty sure I would see a higher percent gain, doubt I could pull 5 mpg off though. I didn't install mine for mpg gain as much as to help that little 2.3L at the bottom rpm range. That I can say was a success. If they still made the Ranger today I would bet that it would have an electric fan the same as the F150. Nobody needs a Mark8 fan on a Ranger.

I was talking about a cheap setup that many people use, with the fan on low all the time. It would not be with a proper controller.
You might, but he has a lifted V6 so he definitely doesn't.
You don't, but a V6 towing a trailer does. It is exactly the right size for a V6 Ranger.

^definitely helps with towing it can run at high speeds when stopped to help cool trans and coolant which can get extremely hot while towing. Ive had a 14foot double axle flatbed trailer behind mine that loaded weighed in right at max for this truck and i never saw it above 195 degrees with my mechanical fan it stayed around 205-210 which is way to close to max temp for me.

I base this on a Mark VIII fan. Real Mark VIII fans draw a tremendous amount of current. I seem to remember people seeing spikes above 50 amps when on high on start up. That is why I would question having or needing one on a Ranger. A Taurus fan is not the same thing. There are many electric fan combinations from many vehicles that would be better suited without such a tremendous load on the electrical system as a Mark VIII.
#42
And that is exactly the problem. Unless you are just putting around in an empty 4-banger, you do need a powerful fan. A Taurus fan was only designed designed to cool a car, and even it draws a lot of amps. The Ranger's electrical system was not designed with that in mind.
Also, I'm not sure if you are aware, but most Rangers to not have an electric aux fan for the a/c that you describe on your truck. So a conversion would need to handle that load as well.

Two weeks ago I got 2003 Ford Ranger 3.0L V6 FFV 5-speed Automatic. Over the weekend Replaced Radiator, Water Pump, 180 degrees Thermostat, & Replaced Fan Clutch to Electric Fan. Most difficult part for me was wiring Electric Fan due to lack of automotive electric knowledge & experience. So did lots of web searches & youtube.
First, I hooked Imperial Adjustable Thermostatic Fan Control (temp sensor) with 30 amp fuse direct from under hood 12V battery power source to e-fan. This was most simple set-up and worked but down side was fan came on for few minutes to cool radiator after shutting off truck. This could be good for truck engine to cool or bad that fan might drain too much battery.
Second, following day I found a 12V Ignition on power source in fuse box. My 2003 had an empty 12V ING on power inside fuse box #20 slot. Now, no more battery drain after park but A/C would not blow cold air while idling at traffic light. This was due to Thermostatic Fan Control (temp sensor) was not kicking on Fan yet because radiator was not hot enough to kick on e-fan.
Third, 3rd day got a four prong 40A 12V relay. Using a relay I was able to setup so that fan will come on if I turn on A/C or by Thermostatic Fan Control. I’ll explain from relay connection, relay is marked by # 30, 85, 86, & 87. Connect #30 to under hood fuse panel 12 V battery power. Connect #86 to Ground (connect Fan Ground while at it). Connect #87 to Fuse Holder Line (25 amp or 30 amp) then Positive Fan connection. Connect #85 to Y split wire, connect one to 12V A/C compressor line & connect other one to Thermostatic Fan Control (temp sensor). Last, Connect Thermostatic Fan Control to 12V Ignition on power source. Done! : )
Result, Engine is much quieter compare to clutch fan. Without AC on truck has noticeable more horse power. Have not used up full tank of gas yet on this new setup so don’t know if any gas mileage improvement yet. Over all very happy with e-fan

Efan in 1991 2.3 ranger
Ive read a crap ton of discussions about efan vs. stock clutch fan. But i was hoping to get some input about adding the efan in addition to keeping the clutch fan. Only want to add one because of the ac when i am moving slow or sitting. For that reason i would just wire it to a switch that i can switch on and off. Engine runs very cool always so i dont need it for that.

The point of an e-fan or a mechanical fan is to add a few more degrees of cooling for coolant passing thru the radiator
But no, on the question, having an e-fan and mechanical fan would not help, one would have to be moving more air than the other making the other redundant so you wouldn't get more cooling with both, you would get better cooling with the one that moves the most air, which ever one that is
AC condensers often had a small e-fan attached, you could retrofit one of those to Ranger condenser, they were on when AC was on.
Just need to add a relay to AC clutch circuit that turns on e-fan when compressor is active

So YOU turning on the AC turns on the fan, but fan turning on does not turn on the AC, common issue
Yes, mechanical or electric, each has its benefits and drawbacks
