electric fan

This is a piss poor piece of "Back up info". 42 voters. Thats a pretty small test sample and doesnt mean shit

Technology has got to the point where its pretty damn relieble. If the "proper product" is installed in the "proper fashion" it should last the life of the truck. Im with mjones on this one. Im glad he sees the ranger for what it is and doesnt use outlandish comments that dont apply to our RBV!!!!!!!!!!
BTW i run the stock fan on my rbv, it works, cant complain.

Bergz0 just ask yourself why your buying it.......let me tell you they are a great product but why do you need to change from your clutchfan? Is there a point in your eyes. You just need to read some more, its toobad these treads allways just turn sour with 2 boys haveing a sword fight

I am not afraid to admit when I am wrong. I just happen to think that efans work. I have NEVER had a bad experience with them when installed properly.

BTW, I too have an engineering background.

then imagine, if you will, the power available to the 2 different types of fans. an e-fan usually draws around...say...60 amps at the most. thats about 780 watts...or around 1 horsepower.

a mechanical fan is connected to the crankshaft via the belt. the weak link in this system is belt friction on the waterpump pulley. your mechanical fan can draw energy until the belt begins to slip. i dont have coefficient numbers for that contact point, but im willing to bet its much more than one horsepower (especially since a 120 amp alternator can draw around 2 horses without slipping a belt). thats at least TWICE the availible power than an e-fan. wouldnt that lead a guy to believe a mechanical fan has more AVAILIBLE cooling capacity than an e-fan?

Nailed it!

Wow, you can tell you have never messed with an efan. The Taurus efan, which draws quite a bit of power, doesn't draw anywhere near 60A; it is more like 28A on the high setting and running at full speed. The initial start up spike of amps is about 43A, but that is only a split second before reducing to roughly 28A.

The efan is ONLY going to run when the controller sees the set temperature for it to start. When driving at highway speeds, the temperature will never meet that set requirement, thus the fan will never see a call to start.

Since the Taurus efan draws larger amounts of air, during summer months, the air conditioning will be cooler; experience this myself by taking temp readings from inside the cab with the mechanical fan and the Taurus efan.

As long as you have a fan shroud, the fan will cool a Ranger, Explorer, or Bronco II without any problems. A fan shroud is the 1 key in the whole thing.


I do agree that an efan on an automatic transmission equipped vehicle isn't a good idea as I did see higher transmission temps vs. a mechanical fan.

It's a lot bigger than a sample size of ONE,
who hasn't had ANY BACKUP information!!!

 

[Wicked_Sludge]

yes, its OBVIOUS ive never dealt with e-fans

28amps, thats about 364 watts...thats even less power available for cooling...thats NOT helping your arguement.

that means a mechanical fan has more than 3X the power available for cooling than your e-fan.

This is because the e-fan isn't cooling as well as the mechanical fan! The ATF
flows through the radiator AFTER the external ATF cooler, and if the engine coolant is HOTTER, then the ATF is going to be HOTTER!!

I've never seen you admit to being wrong, but I've caught you a number of times.

And I have to call BS on the engineering claim, unless it was "sanitation engineering." It's VERY clear you don't understand energy, or anything to do with electricity or circuits. Or the concept of testing; that's bread and butter for ALL engineers.

Well...

MAKG has a good point about water crossings. That is why I run e-fans on my TRAIL truck. It works VERY well and is a Taurus unit. The whole idea of pulling a clutch fan off and the shroud to do a river crossing is just f'in stupid. Not all of us still run a worn out 2.9 and most have switched over to 4.0. I'd like to see ANYONE pull one in 5 minutes and then re-install it. Not going to happen.

Bob is correct about higher tranny temps...IF you run the aux. tranny cooler before the radiator, most of us that trail ride our trucks switch that right off the bat. If you don't, you need to go back to Wheelin' basics 101.

To wrap it up, on a street truck...replace the damn clutch with a new one and keep it as designed. If your REALLY going to wheel the thing, toss the clutch fan in the trash and go e-fan (or send it to MAKG, I hear he's going to start a NASCAR fan clutch pit crew. )

Here's a solution (not much thought put in):

When a users puts in a new post, check the title:

if ($title =~ /e(lectric)?\W?fan/i)
{
redirect("search.php?.....");
return; (or exit)
}

The ATF flows through the radiator AFTER the external ATF cooler, and if the engine coolant is HOTTER, then the ATF is going to be HOTTER!!

Anyone who has it setup this way deserves their transmission to over heat and blow up.

The factory setup is aux. cooler, then radiator cooler like I described, to try and keep the ATF temp fairly constant!

Just posted, the factory setup has the AUX cooler before the radiator cooler!

Again, so you can comprehend, this is why your ATF runs HOTTER with the e-fan!!
