Well i was idleing at a light today and i noticed my idle was climing a little and then i noticed damn i was overheating. pulled over and opened the hood to find that my fan was on. i checked all the wires and fuse and then found that nothing was wrong. Then i spun the fan with my finger and it started up again by just a little touch. It did this one more time later in the day and i had to do the same thing.

anyone know why it would keep getn stuck in a weird spot , and not be able to start again without a push? I'm thinking of adding an LED that will pop on when the fan isnt running or when it gets past run temp. But for now i guess i'm gona have to watch the gauge when im stopped

 

Just an example of where e-fans aren't as reliable as mechanical fans !

 

Yeah.. I was planning on switchign into an efan and freeing up the motor a bit.. but after I read how many problems they give.. it just isnt worth it, I would rather give myself an underdrive pulley all aroudn adn just leave it at that.. =)

 

Is the motor completely sealed from the weather and garbage? Sounds like a starter that won't work until you bump it with a hammer. Dirt/crude could be getting into the communtator segments on the motor and causing it to get stuck in one spot.

 

If I were to say my opinion on e-fans, i would be bannned.





Can you tell if it's always in the same spot?? Meaning....a fan blade stopping in the same spot?? Could be that the motor is starting to go??

 

I'll agree that mechanical fans are more reliable. I had an E-Fan and removed it beceause it made my truck overheat but to electric motor failure.

As far as the problem you're experiencing it sound like junk on the commutator or a hung brush. Basically unless you are familiar with electric motors and their parts, your fan sounds screwed.

 

i hate a e fan every sence i put one on my truck it ran hot all the time so i jucked the thing and put the factory fan back in and no problems sence then

 

I had exactly the same problem. The fans don't like Florida heat and being run constantly. I took mine apart and the brushes rusted inside of mine most likely from the salt in the air here. I bought a 16" fan on ebay for like $35 dollars that is half as thick, half as heavy, and still pushes 2500 cfm and it has worked excellent and was cake to put in since the wiring was already there. I'd definitely recommend the same one.

Here is the link to the one I bought, so if anybody is interested I'm sure you can send a message and see if they have anymore 16"s.

 

if electric fans wasn't reliable, then MANUFACTURES wouldn't put them on a car/truck from the factory.....even the Chevy 2500's are now coming with efans on them from the factory......

an efan WILL be reliable as long as you don't buy junk to begin with just like every other part you can buy for a vehicle...

 

Alright, well I'll join this argument here. I replace more viscous fan clutches at work than I do electric fan modules. This is exactly like Maurice said, if you buy crap it will work as such. Factory electric fans seem to work better than aftermarket add-ons in terms of reliability maybe because of how it's shrouded or built for long term durability I don't know. I see viscous fans at work go bad all of the time on Dodge 3.7, 4.7 and the old small blocks because when they go bad the water pump is turning at 750 rpm and the fan is turning at about 60. I have never seen one come in locked up, they've all either been slow, out of oil or noisy. Sure there are plenty of things that can go wrong with an electric fan but how often do any of these parts go wrong aside from the fuse or the motor? That's kind of like the old argument that carburetors were better than fuel injection because they were simpler. Sometimes you have to give in to technology and admit that something more complex works better even if it has a better chance of breaking. So I'll still have a GOOD electric fan over a clutch fan myself.

 

Are you guys running a proper Fan Shroud. Without one you just blowing the air around in the engine compartment, not sucking it in from the outside.

 

damn. i finally got back to reading this thread and alot has happened.

When it stops snowing and getn cold im gona take it off and look at it. its prolly just full of somthn. i actually think i might have gotten some grass/snow up in it from screwing around. or it could be from the road salt getn in the motor. It hasn't done it sense so we'll see. If i have to replace it its no big deal.

Its worth not going back to a mechanical. plus i dont have one to put on lol

 

stop fighting or debating and answer his question!!

I would say that somethings in the motor, if you have salt on your roads then that wouldnt help it. Maby you could try to find a better sealed fan?

 

It just seems like most threads get about 2 responses and then the thread turns in to a debate. He also said he had to run the efan so this debate isnt helping him out any. I know I also like more then a couple people to answer my question so I know everything it could be and for others to confirm what they have said.

Besides we have a section for debates

 

You're right. I've had enough of the garbage. I've have enough of the crap and I'm just deleting all this usless garbage. Its the same people every time and its getting old.
