Temp. switch for E-Fan

[WNY964x4]

ive never had a water pump fail before 100,000 miles...or about 10 years for the average driver. $15 every 10 years is perfectly reasonable.
You're kind of missing the point I was trying to make... it isn't whether you personally have or haven't had a water pump fail before 100,000 mi (and you're blessed that you haven't... but many others have), it's the fact that there's the potential that the water pump will live a bit longer without a heavy fan and fan clutch attached to it.

the serpentine belt turns the water pump whether there is a fan there or not. it doesnt know or care if theres a mechanical fan attached to it. and running an e-fan rather than an m-fan only moves any "wear" the belt would see from the water pump pulley to the alternator pulley.
I disagree... there are no free lunches in this world, and even when declutched a mechanical fan still spins (they never fully declutch), and it takes energy to make the fan spin - both in a steady state, and to accelerate and deaccelerate it. That energy comes from the engine's crank pulley, and the energy is transfered through the serp belt to the fan. Remove the fan from the water pump and the serp belt then won't see the additional load of the fan on it, and you'll save some wear and tear on the serp belt.

my escorts both have e-fans. when they kick on you can hear them running over the roar of the surrounding traffic.
Rangers aren't Escorts, and on the boards Ranger owners have repeatedly reported that although they can faintly hear their e-fans running with their vehicles stopped, out on the road they can't hear them at all. This has been my own personal experience as well.

even while towing, my mechanical fan is quieter than a sufficiently sized e-fan.
Ranger mechanical fans are notoriously noisy, and you're the only one that I've ever heard make the claim that their Ranger's mechanical fan was quieter than their electric fan... which brand and size of e-fan did you have on your Ranger? And why did you take it off and put your mechanical fan back on?

you dont get better mileage from an e-fan either. look into the law of conservation of energy if you dont believe me.
Sorry, I'm not all that smart that I'm going to be looking into the law of conservation energy, but my common sense tells me that if my mechanical fan is always running and my e-fan is not, then it's going to take more engine energy to run my mechanical fan than it will my e-fan. The saving of engine energy equals better gas mileage, and my before e-fan and after e-fan gas mileage readings confirm that in the real world I am in fact getting better mileage... it's not a huge jump, but in today's day and age I'll take anything I can get. In addition to my own personal findings, other Ranger e-fan users have posted on the forums that they too are getting better gas mileage after converting to an e-fan.

when mechanical fans fail, 90% of the time they fail in such a way that they are locked in the full on position. this will not cause perminent damage/overheating/stranding the driver as will a failing e-fan:
The vast majority of vehicles sold in the last ten years or so have come equipped with electric fans, and seeing as the roadsides aren't littered with vehicles that have had their e-fans fail, perhaps e-fan failure isn't quite the issue that you think it is. And believe me, a mechanical fan failing and going through your radiator is going strand you every bit as much as an e-fan failure will.

Apologies for the dead horse beating and the length of this post.

ok , to put this to bed , when the truck was built , did it leave the factory with an e-fan or an m-fan , think about it , obv. if it was there in the first place , it was designed and meant to be there , do not mess with the factory design it was designed that way for a reason

and as for the serp belt , the waterpump is still there isnt it ? , the serp belt runs the water pump , and the fan is connected to that , ergo , it does not matter if you remove the fan , the load is still there , the fan can only spin as fast as the engine , and when the clutch is disengaged , it spins much slower , there is a reason you can grap a m-fan when the clutch is not engaged , and , when the e-fan engages that draws amps , up to 60 at startup of the fan and 20 as it continuosly runs , which causes a draw on the alternator , and in turn more stress on the belt , and i know the amperages because i had to test them in my college class

as fo the noise , the only time i hear my fan is when i first start my truck , i do not know who you talk to , but my m-fan is a hell of a lot quiter than the e-fans i have dealt with , especially on my slomaro

ok...... so what are your feelings on the probes that fit in between the radiator fins??? Sounds like garbage to me but i dont think that i got much choice....

Where is the provision in the taurus?? is it in the block???
Thanks

i have been using the radiator switch for 4 years , never any problems.

and heres my story, everything was good until i converted my truck to 4wd, then the radiator seemed to want to get packed with dirt and mud when off-roading, so i decided to put the stock fan and shroud back on to keep the mud out, well my MPG went to shit. i was averaging 300 per tank, then it dropped to just over 200 miles per tank. serious noticeable difference!

so i decided to reinstall the E fan but i made some brackets and mounted it to the stock shroud. so i get my MPT (miles per tank) back and no more mud caking at the bottom of the radiator.

the "anti electric fan gods" can preach all they want, there is a difference!

well you also have co consider the fact that you turbed a 2wd into a 4wd , 4wd's get worse mileage than 2wd

after the conversion i did not notice any drop in MPG until i put the stock fan back on. not a "noticeable" difference anyway

there is nothing wrong with electric fans, ford did not put one on the ranger V6 (there factory installed on the newer 4 cyl) because of cost.


i run the same fan on my 78 mustang 12 second drag car.

your fan clutch is broken.

it's the fact that there's the potential that the water pump will live a bit longer without a heavy fan and fan clutch attached to it.

even if the water pump lasts HALF as long with an m-fan, it still only costs an average of about $1 a year to "run". if your worried about $1 a year in routine maintainence on your vehicle you should probably take the bus

even when declutched a mechanical fan still spins (they never fully declutch), and it takes energy to make the fan spin - both in a steady state, and to accelerate and deaccelerate it.

a properly working and disengaged fan can be stopped with one finger. how much horsepower do you think one finger produces? furthermore, the fan does not speed up and slow down with the engine when its declutched as the air resistance of the freewheeling fan keeps it at a pretty constant speed.

Remove the fan from the water pump and the serp belt then won't see the additional load of the fan on it, and you'll save some wear and tear on the serp belt.

then when the e-fan kicks on, it puts the load on the alternator which...you may have noticed...is driven by the serpentine belt. you arent eliminating the load...your just moving it (and in most cases, increasing it, as ill explain in a minute).

Rangers aren't Escorts

your absolutely right. my escorts have a dual core radiator and make about 26% less power than most rangers, meaning they can get away with an even smaller (and quieter) fan.

but my common sense tells me that if my mechanical fan is always running and my e-fan is not, then it's going to take more engine energy to run my mechanical fan than it will my e-fan. The saving of engine energy equals better gas mileage

again, a free wheeling m-fan takes a negligable amount of energy. on top of that, an m-fan draws its power directly from the serpentine system, which means it incures no extra losses. an electric fan adds into the equation the very inefficient design of the alternator (only about 50-60% efficient), and the aditional inefficiencies of an electric motor (no more than 90% in most cases) meaning your electric fan has an inherent 60-70% energy loss whenever it is running. the only way this system can be more efficient is if it sacrifices cooling power for economy (which is a whole other can of worms if you live in warm climates or tow).

well you cannot compare a 12 sec , built fo speed drag car to a ford ranger pickup , there is a huuuge difference

so basically you just said in a more eloquent fashion what i was trying to say earlier

your fan clutch is broken.

i'm sure it was with only 7 thousand miles on it when i removed it!

serious, no there was nothing wrong with it. i'll send it to you for free and you can check it for yourself.

sorry if my truck dosn't comply with your "anti mod" theory..

again, there is only 7K on my OEM fan clutch, there is nothing wrong with it, i choose to not use it, thats my choice. never any problems with it (or the electric fan). i have even towed a 1000 pound trailer up north and the trans never got above 190 degrees, yes i have a good scanner and watched the live data the entire way, 206 miles one way (with the A/C on). of course i have also "tweaked" my transmission and bypassed the temp flow valve.

well i towed about 6000 pounds with my 96 5-spd , with a m-fan , and i never had any problems , i dont think an e-fan would have been adequate

 

[Wicked_Sludge]

then there was some other "foul play" at work. assuming you put about 17 gallons in, going from 300 miles per tank to 200 is going from 17 MPG to 11. it takes more than an e-fan switch to create a 35% change in economy. WAY more.

 

[04 EDGE]

i towed my mustang on a full tandem axle trailer a few years ago, middle of summer, with the A/C on, only a short distance, maybe 20 miles, never overheated. and you over rated the truck towing a 6K lb trailer.

you guys need to get over yourselves, this argument was old 5 years ago!

you do know company's sell e fan kits for superduty diesels right?


if its installed right and controlled right there will be no problems.

 

[Wicked_Sludge]

theres also a company that makes a little metal "air swirl" gizmo that sticks in the intake of your ranger. i REALLY hope you bought one (they wouldnt make it if it didnt work, right?).

just because it exists doesnt make it a good idea.

and your right, its an old arguement. but i dont have the resources to run trials to prove my side of it...and noone has offered conclusive prove to the e-fan side of it....so thats why its still up in the air. all i can do for now is back by reasoning with math and facts to counter youre "whelp, werked fer me" claims

well if you want "real world" facts then feel free to come spend a week with me, i will put the stock fan back on and burn a tank, then put the electric fan back on and prove it to you.

you guys and your "closed minds" are out of control.

its like going through life with blinders on isn't it.

again, 4 years and over 50 thousand miles, ZERO problems (besides my own , IE off-roading)

well the trailer was 1700 pounds , the truck on it weighed about 4300 , so about 6k total , and i do not doubt that set up right they are useful , but i why do it on something like a little old ranger , a superduty , yes because they are designed to tow , but a ranger is a small truck , not a 1 ton twin turbo'd diesel designed to tow 12k pounds

please explain to me what the difference is between installing an electric fan on a superduty and a ranger?

i seriously think you two browse these forums everyday looking for this topic!

reminds me of the republican party for some reason.
