Ford Super Duty (1999-2016) :: 2011 F250 - Fan Is Making A Loud Sound As The Motor Is Accelerating
Sep 18, 2014
Picked up a new to me 2011 F250 Lariat. She had a few odds and ends to take care of, but I was ok with that. So far I fixed the reverse sensors (2 were out) creaking in the back (leaf spring bushings needed a little Lithium Grease) Squeak in the back (tailgate step needed a little greasing). Now on to my next problem!
This is my first 6.2l (first f250 in general). Truck starts up great and idles quite. Taking off driving, it sounds loud as hell under the hood. To me it sounds like the Fan is making a loud sound as the motor is accelerating. It is more noticeable when you really floor it. Prior to this I owned a 2010 F150 and I know stomping on it the motor really revs up, but this other sound to me isn't right/normal. Googling around, the closest I found to it was:
Loud "Air" Sound Upon Accelerating 2002 FORD EXPEDITION - fan clutch! - YouTube
Granted it's for an expedition, but the sound is damn near identical. Looking on youtube at 1 or 2 videos of a f250 doing a 0-60 all I heard was the sound of the motor revving, so that has me convinced the sound I'm hearing is not normal. I'm 99% convinced it has to be the fan clutch.

I drive a 2000 F250 5.4L. Currently has about 168,000 miles on it. I changed the oil the other day and cleaned the air filter. I used what I usually use on the oil change which has never been a problem. But this is first time to clean the K&N filter. A day or so later my engine is making a loud air rushing noise. Under throttle the engine compartment sounds like a wind tunnel. At 3500ish rpms it makes a harsh whistle noise. The air rushing noise doesn't go away once its warmed up or after the engine has been cool. Noise didn't go away with the filter being taken off either.
Could all of this be caused by cleaning and not using k&n air filter oil (but rather WD40 upon Dad's suggestion)? Or is there something else going on?

Here's a link to a video where you can hear what I'm describing. The noise is most noticeable around the start (first 18 seconds) and the end of the video when I'm closest to the exhaust pipe:
YouTube ....
You may need headphones to hear it, but the engine seems to be making a bit of a puffing sound during idle. It happens completely randomly and I'm not quite sure what could be causing it.
Aside from this noise, the engine seems to idle normally, and the check engine light isn't on. I had all of the injectors out a few weeks ago for cleaning. They all appear to be working fine. I also cleaned the throttle body at that same time and ensured there were no obstructions for the air intake and filter.
What might be causing this sound? 1999 Ford F250 Super Duty 5.4L

Have a Whistling or hissing sound while accelerating? My 2015 6.2 seems to make this sound while under load. I took to dealer and they claim its the throttle plates not closing all the way. Claims this is normal, but to me it is annoying. Just would like to know what others think.

My 2003 F-250 5.4l gas started making a recurring clicking sound from under the dash on the left side. It started last summer and would repeat numerous times each time I had the truck out. It's the kind of sound the turn signal makes. Always 5 clicks. It stopped happening when the weather got cold here in Canada, but started again this week (maybe because of the the warm weather we're having). How do I troubleshoot what the issue is? If the headlights are off it also flashes the lights in the instrument cluster five times.

My 11 cc lb 4x4 6.2 has a clunking/loose sound coming from the front end. It is prominent when going over small/medium bumps but not so much large bumps. I have had my local dealer and a couple local shops look at it and they all say everything checks out. It definitely seems like something is loose in the front suspension. I just put new Gabriel max control shocks on all four corners. I have no play in wheel bearings or ball joints. Tie rod ends also look fine.

Just became the proud owner of a used 2011 F-250 Supercab, 6.2L. Overall the truck is great but it does have a-few things that need fixing, the most annoying of which is a knocking sound from the rear passenger side cab corner. Sounds like the exhaust vibrating and smacking up against the floorboard but that's not it. Everything seems tight, even the front suspension.
The only thing I can see that may be the cause is the rear passenger cab mount seems worn. I can rotate the bottom rubber portion without too much effort and when I feel for the top rubber portion all I feel is the metal cup on the top, like the rubber has collapsed and the metal cup is sitting directly on the frame mount.
So... how many cab mounts there are for the Supercab? I think there are two on each side and two in the front. All of the information & videos I've seen describe the locations for the crew cab. Also, is it possible to replace the cab mounts and not have to mess with the ones in the front? I hear those are the real buggers.

I have a 2003 super duty V10 4WD super cab long bed.
loud deep rumble noise when turn on the blower. both heat and a/c. removed the blower and seemed to turn ok. blew out all vents. removed heater radiator cover, checked most flaps to see if working. doesn't seem to be obstruction invent. the flap behind blower clear and functioning ok.
When on second speed, almost sounds like blower motor is out of balance. if run on high for 1 minute, smell electrical burning! Think to replace motor will work? will post another issue with radio and power windows

I have a 1999 F 250. When I accelerate my AC from the vents changes to the defrost. Other than that it works great and is ice cold. Why it's doing this.

My battery light on the dash came on so I tested the battery and it's OK. The last time the truck was started it was 10 degrees and ran for about 3 minutes and shut off because I knew the alternator had to come out. Next I pulled the alternator and had it tested and found to be bad. It was rebuilt and put back in along with a new belt. The motor cranks over well but will not fire. I checked the fuel pump shut off switch and it had not popped up so it seemed fine. The fuses look ok. I ran the battery down a bit so I put the charger on it to bring it up to full charge. When I pulled the alternator I touched it's battery wire to metal for a split second. Sounds like I need to do a pressure test on the fuel system or listen to see if the pump is starting. The truck has 130,000 miles on it.

I just bought a 95 f250 4x4 with the 460. The guy i bought it from had a trans slipping towed it to the shop when the shop went to pull it in they started it put in gear and engine died. The motor is now tight w no movement either direction with a bar obo it. Is it possible the trans is holding the motor tight? What can I do?

My Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

I have a older minimax with the latest updates and have noticed that under full acceleration the tranny seems to rev up faster than the truck is accelerating. This occurs i think in 3rd gear like accelerating onto a on ramp etc. Kinda like its slipping if you know what I mean. I'm running the mild tunes in tow mode. Everything else seems ok.

I have and 07 F250 and the #2 speed for the blower motor don't work (hasn't since I bought it) I read that the most common cause of this is the resistor under the hood on the firewall so I replaced that and still no 2nd speed??? Where I look next? Motor itself maybe?

A buddy of mine has a 99 F250, and the 4WD stopped working. The 4wd light in the dash does not turn on with the key with the rest of the lights. There is a Low Range light that does turn on. He took it to a shop/dealership and they said the vacuum was good. They also swapped in a different GEM module, which didn't change anything.
I swapped the relays under the hood - no change. I keep reading that there is a two wire plug on the transfer case I can test for voltage or to manually power the motor. Where is it? I see two plugs - the blue one on the left has 4 wires, the black one has more. Or is that not the shift motor I need to be looking for?

My dad has a 04 f250 5.4 auto. The motor turns over but very slow and will not start. He's put two new starters on. I went and looked at it and figured it was loose cables or corrosion, but it was fairly clean, and tight. We decided to pull the battery out of his van that he drives everyday, and I cleaned everything very good. Same thing. Pulled the belt to make sure nothing was lockup, same thing. Truck was running and starting great, then just did this one morning on him.

My HVAC blower motor stopped today while the wife was driving the F250. I thought I should swap relays (with the heated mirror relay - same Ford Part Number) to rule it out or identify it as the culprit. However, since these are close to the firewall, I have a hard time getting the grip and leverage to pull the relay out of the Battery Junction Box (BJB). How to make this a bit easier?

I've had the 450 a little over two years. Its used 95% of the time for hauling trailers, including the toy hauler. Has not given me a single problem since day one and now has around 21,000 on the odometer.
Lately I've noticed a "grinding" sound coming from the front end somewhere. It is most apparent when I'm turning at slow speeds; especially left. To describe it would be similar to worn out brake pads or maybe a wheel bearing going bad. It does it whether I'm on the brakes or not.
