like i said in my previous post, unless you are overheating, or just starting out first thing in the morning you should not be hearing the clutch fan, if you are hearing it constantly you have a bad clutch

This statement is, to put it simply, 100% wrong.

Throw a 6,000 lb boat on the back and pull it 150 miles on a 100 degree day.

I read somewhere that trucks like this, while towing, generate enough heat to keep two normal sized family homes comfortably warm on a cold winter day. That's a lot of heat that needs to be dissipated by that fan. (It's also where a lot of your fuel dollars are going, but no real way around that until cars are redesigned from the ground up....) You want as much air flowing as possible.

I agree with Sharps. If your clutch fan is causing you noise issues, then you need to replace the clutch. Plain and simple. I never even hear the fans on either of my Durangos except for a few minutes after startup in extreme cold weather.

Replace the clutch. It will be cheaper and easier than converting to electric, and you'll have a stronger, more reliable cooling system.

Look at it this way, when your fan clutch failed it locked your fan up and made it run TOO much. When an electric fails it stops spinning and you overheat and call a tow truck. In my mind that qualifies as "case closed" in terms of which is better.

If you read everything you would already know that I don't do any towing. If I did, I would definitely NOT remove the clutch fan. I just don't like how loud it is and my fan is NOT seized up.

if you are hearing the clutch fan running during normal driving (i.e. not overheating) then it is either siezed, or on its way to being siezed i GARANTEE IT!!!!!!!!!!!!!!!!!

noone else can hear their clutch fan over the running engine during normal operation, therefor your fan clutch is acting up PERIOD!!!!!!!

Yeah I agree with shrp, to be honest I think my electric fan is louder than my clutch fan LOL. I have a flex-a-lite VSC granted but when it's on full blast, it's still not louder than my engine roar.

You shouldn't hear your fan going while you're driving down the road like shrp said and if you do, and you're positive your clutch fan is just perfectly fine, I'd look into something other wrong other than your fan.

Not taking sides on this one because I don't take sides, but I believe theres some more issues beyond a fan clutch if it's so loud you can't hear your engine.

It only re engages after i idle for a minute or so. While idling or at normal cruising speeds it disengages as it should.

Replace the fan clutch! It sounds bad to me hands down if it's engaging all the time.


I wonder if what he's trin to say is; when the clutch fan is engaged the engine ROARS and it is louder that his exhaust and normal engine noise level. If this is the case then I have to agree. During cold start up most likely the fan will be engaged until which time the clutch disperses it's oil and relaxes the grip on the water pump shaft therefore allowing the clutch fan to relax and run for the most part quite.

I find it quite comical, every time I start my truck cold and take off it sounds like a freakin tornado! The clutch is locked in position and on a V10 it seams 3 times louder than my old 9 fan blade 1998 5.9L built Durango. You wanna see people look, I laugh my *** off and think I'm a bad *** when drivin bey.....Ok on the up side of my ego.......My Durango did the same thing and that is normal.

If "MoparMan" is asking if that can be fixed then no it can't as that is how a clutch fan works.

I know thats how they work. Im just saying I hate my car sounding like a tornado on startup and when I stop at a red light. I want to hear my engine, not my fan.

I actually just replaced my fan clutch 2 days ago because I never heard my old one. It was bad. Now I hear the new one for about the first 10 or 15 minutes of driving and after that it dis-engages. It is very loud though at first start-up. It will engage if I come to a light or come to a stop. Is this normal?

Yeah that it normal. And that is the what I am addressing. I dont like how loud it is and I dont like it engaging when the engine isnt over heated and when its 32 degrees outside. I can understand if its a typical 100 degree summer day here in omaha but its freezing out, literally.

Ya, its cold here too. It engages at red lights on my way home from work when its in the 20's. Before I replaced it I didnt know it was going to be this loud. It feels like the truck has about half the power when the fan is engaged too. I watched my mileage counter last night go from 9 mpg when the fan was engaged to 16 when it dis-engaged.

Yeah I hear you. I read that while engaged it can steal anywhere from 15-20hp from you. I usually get about 16-18mpg regardless but I didn't get it for its eco friendly ways. The noise just really irritates me, I find myself flooring it to make the fan disengage sooner just to avoid the noise it makes. That's why I want to just remove the thing and see what my results are.

If you don't like to hear the fan then why don't you just remove it and go to an e-fan modification instead.


It is normal to hear the clutch engage at cold start up for the first few minutes and on a new one it will loosen up after it wares in, but just siting for a few minutes at every light and being 32 F outside temp, well it sounds like yours is on the way out and needs to be replaced. Also, you can always put a louder muffler on it so you can hear the motor.....LOL

I just read an entire thread where IndyD installed an electric fan and it looks like a lot of work.

Not really!


But if you don't use it for work why not follow his lead and that will fix your issues.

Yeah I know. I'm not saying that I will never use it for work but I figure if I can get a big enough E fan then it shouldn't be a huge worry. I'm still concerned with disassemby, wiring, and reassembly. If I knew someone personally that should assist me with this then I would jump right on it.
