Ford Super Duty (1999-2016) :: Freon All Leaked Out Of AC Compressor And It Is Squealing
Jun 25, 2014
Of course my freon all leaked out of the AC compressor and it is squealing pretty bad. I did not want the serpentine belt to break due to a seized compressor so I looked for a bypass pulley kit. Naturally they make one for both gas engines, but not for the diesel. So out comes the string and sharpie, and trips to 2 different auto parts place to get the correct length belt after trying several that were too short. It's 103 inches (8 groove) for future reference to bypass the ac compressor and upper extra pulley. 7.3 diesel.....

Seems like my 2001 f350 7.3 has an ac freon leak on pass side near compressor. AC is blowing coolish air but not cold like is should be. There is green like oil around main line leading out of ac compressor. I have attached several pics to illustrate situation.

I had a new engine put into my 2006 F350 SD 5.4 last year and ever since then I can't keep the freon charged in my ac. The mechanic said all he did was lay the compressor out of the way and didn't disconnect anything ac related. I have 2 different shops keep my truck for a couple days and neither could find a leak. Yet a month later, freon is low. I think I have more dye in my system than freon.
I put 2 of those ac leak sealers, the ones you have to ask for behind the counter and can keep my ac working for maybe 45 days, then throw 3 cans in it. No dye is showing up nor will the sniffer find anything. I hate to go to the dealer because I figure they will want to replace everything. Any tips other than try another shop and maybe they can find the leak.

So I've worked on this A/C for 3 years, I don't drive this truck very much or often, partly because the A/C doesn't blow cold. Its a 99 f250 7.3 ... Here's what I've done, first it was low on Freon so I added some and it got cold, take off driving and it gets hot. After some research I check the clutch air gap and pull a washer. This changes nothing, I put a valve on the heater core, so I could manually shut it off just in case.
This year I replace the compressor because the clutch isn't staying engaged when I revved it up in neutral. I went ahead and replaced the drier and Orifice Tube, the orifice tube was clogged up. So I start recharging the system, and I get 2 3/4 cans in and its blowing cold, low 50's high 40's its 75 degrees outside. The gauges read 35 low and 300 high, I'm a little confused cause it was suppose to hold 41oz from what I looked up but ok.
I rev the motor just to check everything out, the low side heads down for a second then starts going up, the high side starts going up and doesn't stop. The high side goes all the way till it hit the high pressure switch 450 wow. I'm thinking its over charged, I let it idle and the compressor kicks on and the low is around 50 and the high is at 350. So I rev it up again 1800 rpms or so, and the low side drops down and so does the high side. Except this time the low side drops down to 15 " I had the low pressure switch unhooked and looped" and the high side around 225.

I have a 99 f250 4x4 super duty. Just started getting a loud squealing noise off and on in the front end. Changed the ujoints and axle seals on both sides. They where all in bad shape. It still makes the noise off and on while in 2wd. If I lock the hubs in it doesn't. What it could be ?

Tried using the search function without much luck. My brakes started squealing so I know it's time to replace. I use my 2wd 250 truck for work mainly and it has some weight on it. Most of my driving is stop and go. I use it to tow my Jeep maybe 3 times a year as well.
What are the best pads to go with? From what little I found using the search function it seems Hawk LTS or OEM from the dealer, not Motorcraft from the parts store.

I've replaced the pads and rotors on my 97 f250 HD, only to have constant squealing. I've replaced ranger rotors before with no problem but this has been an adventure. It's squeals constantly up to 35, (I've only went up to 35) and squeals louder under braking. Just looking for some pointers. Probably just need a good cleaning. The truck is parked until its fixed more than likely.

I can't afford to replace it now and want to quiet the squealing that occurs only when I turn right. A mechanic sprayed something on there about a month ago that caused the squealing to stop for about a week, but don't remember what it was. It's a 2002 S.D....

2012 6.2 XLT 50,000 miles with manual single zone controls. I haven't had time to work on it yet, but it seems that my AC compressor is not engaging. The dash controls light up normal, fan comes on, etc. I am just looking to see if there are any common failure points. I know it COULD be low on charge, clutch could be bad, etc. I am just checking if there is a common failure with these trucks AC system.

With the few hot days we have had here lately, I have noticed that after about a minute the AC will go warm and I will have to rev the truck up when it does to get it cold again. It seems the compressor is disengaging. I noticed that the condenser has a big gash with a tube ripped open on top. I know it needs to be replaced, but could that be causing the compressor issues? It's a 2003 7.3L.

Ok AC wasn't working took it to a mechanic told me the the compressor was missing a clutch he recommended i put a new compressor. Is it possible just to put a new clutch in it and if so do i have to remove the compressor to put the clutch on it.

I am not sure which it is but I cannot turn the pulley by hand. How do you tell if the pulley is bad or the whole compressor? I went out to start the truck and it wouldn't start. It died so I restarted it and then I seen the smoke from the front of the truck. I opened the hood and the flipping belt was just hanging there. Is there a way to just bypass the unit for now? I wont be needing the AC till summer and that is several months away.

So When driving around I'm hearing this squealing almost chirping noise and it sounds like its coming from the rear of the Truck. I greased the bushings and leafs but that didn't fix it, to me it sounds like a rotating noise. Don't think it's the brakes cause it makes the noise when driving not stop.
Also, a bad alternator would make noise while driving over 40+mph, like a loud whistle?

So a few months ago I would occasionally hear what appeared to be a slight squealing noise from a pulley when I started my truck. It was very intermittent, so I didn't think much of it.
After a few weeks, I realized I was only hearing it on colder mornings - it would also go away rather quickly. I bought a mechanic's stethoscope, and figured I'd get to it on a slow day.
Today, I finally broke out the scope and tried to figure out the source. Didn't really find any pulleys making noise, and I did notice that when I shut the truck off, it squeaks for a second or two as it comes to a complete stop.
My dream of finding a bad pulley or perhaps a power steering pump was crushed. I had hoped to do a little Easter wrenching and put this noise to rest. So, I did what any good mechanic would do - I Googled the issue.
I'm reading that it could be the belt. Certainly wouldn't bother me too much as that is an easy fix. The belt isn't too old - about 4 years and 20 - 30K on it.
I took a few pics of the belt and can take a video of start/stop ....

The pads were replaced 5000 miles ago. Today the truck is acting hard to go, brakes are squealing, and I noticed a hot brake smell. I got home, grabbed a remote thermometer gun and the front rotors are 130 degrees, the back ones are 650 and 700 degrees! Super hot. I'm going to NAPA for new calipers and pads. I hope that fixes it.

The front brakes on my '02 Super Duty squeal a little from time to time, but today have been squealing mildly while driving and get louder the further down I press the brake pedal until coming to a stop. All new brakes were installed less than one year ago.

Truck details:
2008 f350 6.4 290,000 klm
DPF and full EGR delete
K&N intake
IDP custom street tune
Loud squealing noise that happens when cold or at temp.
2000 to 2500 rpm's to 3000 rpm then it goes away
Happens only when accelerating over 50% anything under and the noise doesn't happen.
15 to 20 pounds of boost
Turbo sounds good
No codes
All plumbing looks sealed and tight
Fuel coolant res is full and clean
I'm thinking it could be the lift pump dying or having trouble supplying the fuel demand. Started after I did the cold air intake....

Having an issue w/ my 00 550. When I lock in the hubs there is instantly a noise, More of a squealing then a grinding. The truck goes in and out of 4x4 no problem and the noise is there locked in 4x4 and not locked in, as long as the hubs are locked in. I can't tell if the noise is coming from the 4x4 driveshaft but there is no noticeable play in the u-joints or the u-joints in the front axle. I did notice when I spin the 4x4 shaft by hand the passenger side joint spins slower then the driver, not sure if that's normal or could be the problem.

Got a 06 F250 V8 Gas. Went to turn AC on the other week & got warm air out vents. Put 1 can of 134 in & the gauge on the "kit" said it was in the green. It was working last summer. You can turn the compressor "face" so it's not locked up, but it's not kicking in. Swapped the replay with another one & the 10a fuse in the fusebox under the steering wheel is good. Is that the only ones? I find it hard to believe that it's something serious. We did change the belt a few weeks ago & I was hoping that we had pulled a wire loose. The vacuum line that plugs into the heater hoses is plugged in.
