Ford Super Duty (1999-2016) :: Slight Whistle At Certain RPMs / Noisy When Temp Turned Cold
Dec 14, 2013
I have a '13 6.2 with 11k on it and it's started making a weird noise since the temp has turned cold. At first I noticed a slight whistle at certain rpm's but the temps were around 0 so I didn't think too much of it since stuff gets noisy the colder it gets. Today the temps were in the upper teens and I'm noticing a new sound. From around 1000-1500rpm I'm getting a whining sound that is noticeable in the cab. It's coming form the engine since it does it while sitting and I can make the sound appear by getting the engine at the correct speed. It's louder when the engine is cold but I can still notice it a bit after the engine is at operating temps. Below 1000 and above 1500 rpm there is no noise. I never really noticed it before, but since I heard the slight whining last week I've been listening more and I know that's when you start hearing noises that you normally wouldn't pay attention to.

I have been having a problem with my 2002 F250 Super Duty 4x4. It started about 2 months ago. I was in traffic (truck hadn't even been on for 15 minutes). The temp gauge spiked, so I pulled over and turned the truck off. I turned the ignition on and the gauge was normal so I started it and all was fine.
Fast forward a little and every so often about every 3 weeks it would overflow (coolant) but not get to the point that it would overheat. I changed the thermostat and all seemed good to go. Fast forward to yesterday morning. Got in the truck and left to go hunting, and I didn't even make it 10 minutes down the road when I turned the heat on and it blew cold.
I started to see the gauge creep up so I pulled over and shut it down. Upper hose was cold, lower is cold and both heater hoses are cold. After some time of waiting, I started it but the gauge kept creeping up and no heat, so I kept shutting it down. After about 5x of this, the heat worked and the upper hose got hot and all was right with the world. SO I drove it home. Coolant is new, flushed about a month ago and was running great since then. Thermostat is new. Do I have a blockage somewhere? Water pump bad?

I noticed a slight whistle last year coming from my front left hub. I pulled the hub and greased the gears as best I could and it sort of went away. Now this year it is a little louder. It only happens when the hub is locked. Is starts around 20mph and goes away at 40. Is the bearing in the hub shot or is this normal. 4x4 works fine and there is no visible excess wear on the gears. The truck has 93k.

The truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.

I have an 03 f250 6.0 150k milage and lately my A/C has not been working at its best. Its intermittent, and for some reason it will work fine until i get on the highway and it just blows hot air. Would this be a leak or clutch issue? One thing I have noticed if my oil/coolant is above 200 the A/C will blow hot air but not return to cold when the temperatures return to normal. I haven't done any trouble shooting so my first thing ill check are the fuses. As far as the compressor goes its an alien object to me I have never had A/C issues with any vehicle i have owned.

My CC display shows all icons on the right regardless of settings (see pic). The temperature setting and outside temp will not come on.
The second issue is that my front blower starts to lose velocity and sounds strange on long road trips.

2015 with a 6.2 and 1200 miles. I have a whistle coming from under the hood. I didn't here it at first with the windows up and AC on but now that its cooler I have the windows open. I only here it at 2000 RPM or under while accelerating. Doesn't seem to matter how hard I am on the pedal or how heavy the load.
Dealer is going to have to fix it but would like to get a heads up for what it could be.

2007 F-350 4X4 King Ranch... I have the 6.0 diesel. I am on the road to Houston, Tilden and San Antonio TX, and I am noticing a whistle on acceleration. I can change the tone by how hard I push down on the accelerator. I thought it was a radio issue and turned the radio off and got no change. Turned the a/c off, no change. Down hill or coasting, nothing.

I have a whistle from my 2000 f250 super duty when driving over 60 mph. windshield is new, seal around windshield is good (looks good to me).
whistle sounds like its on right side when driving, and left side when sitting in pass side. wife narrowed it down to the over head console sunglass pocket is where whistle is loudest.
Could the clearance lights be whistling? How does one tighten them up or add sealant to the bottom of them to seal them to the roof. Do I have to drop the front of the headliner to access them?

I have a 1999 F250 V10 SuperDuty. Just recently I had noticed some gray foam material laying on my passenger floor. Then about a week later my air vent near the passenger window is whistling really bad when I have the air on. I normally have that vent closed. Is there an easy fix for this? My guess is that the foam inside has deteriorated and broke apart.

I bought the wife a truck a few weeks ago and she said the heater wasn't working well and was noisy. So I hoped in it at lunch today and she was right, barely any heat output and its noisy coming from behind the passenger airbag.

I have a 2002 f-250 7.3 diesel, i straight piped it but only by cutting muffler off and welding a piece of pipe in its place, it is pretty loud but id like to hear the turbo more like more of a whistle, it has a pretty good whistle once i get past 1500 rpm, is there a slightly bigger turbo i could put on without putting too much strain on the 180,000 mile engine?

I'm have a 2011 6.7, 180,000. I have noticed a high pitched whistle, not an turbo whine, that disappears after the boost drops to less that the first mark on the gauge 5-10psi??? It stays consistent in tone, the mileage is good, power is good normal 6.7!!.

My 2008 rear suspension creaks and squeaks and groans when I move my horse trailer. Truck has 32k miles, has done since purchase last year, squirted wd 40 and that works. At ford place now, they say it is because I added the ride rite air bags. Told them it made same sound before I installed. What to tell them (tech service bulletins ?) or give up and keep spraying and looking for dry joint?

My 05 V8 has developed a slight whistle when the air conditioning is turned on and the fan speed is high. This only seems to happen when the system is taking in outside air. If it is recirculate mode, the whistle goes away. It also goes away if you manually turn the fan speed down. My assumption is that something may be caught in the intake.

I bought this Ex a little over a month ago and finally got around to replacing some stuff.
I have a slight vibration between 50 and 60 MPH. The vibration is the same weather I am accelerating, in Neutral, Coasting down (well, a little bit worse when coasting down), in 2WD, in 4WD, turning, going straight, hot or cold.
I have replaced the following:
Rear Driveshaft U-Joints
Tires and Rims
Upper and Lower Ball Joints
Wheel Bearings
Steering Stabilizer
Cleaned and Greased the Hubs
Greased everything greasable up front
I still have the exact same vibration as when I started. I can feel the vibration in the steering wheel as well as in the body of the vehicle. I am thinking that it may be in the steering linkage. If there is a loose joint then the wheels would be allowed to jiggle a little bit. I am at a loss. What else should I check?
Also, When doing the ball joints, I noticed that the tie rod ends were quite stiff. How stiff should these be? I can't move them by hand, but they will move a little bit when moving the free end of the tie rod.
I am taking it in for an alignment on Friday, and if I can't figure this vibration out, I might have them take a quick look into it. Would a stuck slide pin in the front brakes do this? Both sides on my truck are seized at the current moment.

So the other day i opened the door and heard a super loud clunk noise come from the door and when I turned the car on and pulled hte window down it wouldn't go down all the way, only about 75% of the way so I assumed like BMW cars the window motor died but oddly it continued to go up and down just now 100% down.
Then 3 days later when I came to drive the car again the window went down to the 75% mark and now its jammed there with no movement even if I tried to lift the window up myself. Usually a broken motor allows this to happen but since it isn't budging I am wondering if its an electrical issue with the power window button more than the motor?
I say this because when i try to lower the passenger window from the driver side it works than out of no where on the 3rd time it wont move at all than 5 minutes later it will move or if it doesn't move I just go and pull the window down from the passenger side then I come to the driver side and try it and it works again than it'll stop again. So maybe its the power window control buttons on the drivers side that's failing?

I have 05 F250 SD with 150k on it. The engine has the typical cam phaser knock, timing chain slap on start up and occasionally have a noisy lifter. As long as I use fresh 20-40 oil the engine symptoms are less and the engine runs strong. The motor also doesn't leak or burn oil and the plugs were change out about 20k ago.
The truck is still good and is prefect for my needs so to me it's seems worth fixing the needed repairs. What I would like to figure out how far should I take the motor... just have the chains, guides and phasers replaced or buy a rebuilt motor and swap it? I'm thinking just doing the phases and etc would be 1/2 the cost but may not last as long as rebuilt motor. But realistically I might only put 5-7k miles are year on it anyways.
