Ford 6.0L Power Stroke Diesel :: A/C Clutch Cycling Not Much Cold Air
At the first of summer I had typical A/C Clutch cycling not much cold air. Checked the Low Press side said it was low PSI took a Gamble that the pump was good and just filled it worked great. Lost All A/C the other day checked it out thought it may have small leak somewhere but clutch didn't cycle hardly at all Had a gut feeling it wasn't simple leak.
Well I just found a Hole in the condenser at the bottom Tube that runs across. So looking for new condenser. I also don't know what to do with recharging it and the ac oil in the system how much? maybe its safe to say most the oil was pumped out. Would standard procedure be to repair it then FLush cooling system to get to a baseline and then refill prescribed amount of oil and Freon
Ford 7.3L Power Stroke (1999-2003) :: A/C Compressor Rapid Cycling?
So again the a/c in old green gave out. it has been an ongoing battle over the past few years, but this time I took it to a good friend who has all the right tools as our level of frustration dealing with it has peaked.
We removed everything, and got it all "new" from oh-rye-lees. a new compressor was installed a few weeks back and it worked fine, but cycled very strangely. it would rapidly kick in and out, then just stay engaged. found out the condenser was plugged up and thought maybe that was causing it.
At any rate, it now has a new compressor, condenser, evaporator, drier, orifice tube, and low pressure switch. all the lines were flushed and checked.
it was vacuumed and checked, then charged with freon. The compressor is doing the exact same thing! it is cycling very strange. sometimes rapidly at higher rpm, and sometimes it works just fine. the a/c is working, but it is freezing up the drier, evaporator, and line all the way back to the compressor. vent temps are about 30.
The WOT relay and high pressure switch was replaced, and it did not make a difference. we are at a total loss.
We were told by another person that the clutch on the new compressor was too small and that was causing the issue. It measure 4.8" and we were told is is supposed to be 5.3". is there any truth to that? we just do not know what is causing this, but want to get it right as surely something will break if it stays this way.
Ford 6.0L Power Stroke Diesel :: AC No Longer Blowing Cold Air
Ac is no longer blowing cold air and was thinking about trying a can of ac pro on her. However, I have heard some pretty bad stories about people killing their compressors and overcharging the system. Is it not worth the risk.

So, trucks A/C is not blowing cold, and i replaced the compressor a couple years ago ( 40k miles?) took the truck to a shop to have them use one of them sniffers to check for a refrigerant leak. Was told that it needs a new evaporator core. Charged the truck up with refrigerant and it blew cold for a while but is now blowing hot again and it's summer time here in FL
So, replacing evaporator core here? I tried to find some how-to videos on youtube, but to no avail. I'd like to do it myself if possible. I think the shop quoted 3-400 in labor atleast.
Ford 6.7L Power Stroke Diesel :: A/C Just Suddenly Stop Blowing Cold Sometimes
Blows cold, so not a freon issue, but it will sometimes just suddenly stop blowing cold as if I punched the "A/C" button disengaging the compressor. Sometimes if I just wait a while it will come back on by itself, sometimes I have to stop and shut the truck clear off and take the key out, then start it back up and all is well again and it blows cold again.
High pressure switch failing???
BCM issue???
Ford 6.0L Power Stroke Diesel :: Cold Start Blue Smoke Blowing Until Warms Up And Accelerate
I have a 07 6.0 powerstroke, I had 2 bad injectors so I replaced all of them with reman's. I had a problem with them coming loose. the first time this happened it hydrolocked the motor, number 8 cylinder. so I pulled all the injectors and replaced all the seals and washers and torqued them down a little more than spec like 27 lbs. it runs great and starts great even at 25 degrees but I noticed this morning that when starting it up after it sits (cold) it blows blueish smoke until late it warms up and I accelerate. is this normal? should I check fuel filters? oil in fuel?

The clutch in my ac compressor is not releasing causing it stay on all the time and not cycle and get hot and freeze up the system. Also pulley seems to be angled like it's not sitting straight. Can I just replace the clutch on the front? if so what's all involved. I need to do the entire compressor?

2005 F350 6 liter.
AC compressor clutch was toast. Thought it was just the clutch. Started to notice the truck struggling to start, with some smoke on acceleration that was not present before.
Today, paid a guy to replace my AC compressor clutch. He called me out a bit ago to show me what he found.
Looks like it was not the actual clutch. Looks like the bearing on the pulley took a crap. Bearings got wedged between the face of the pulley and the clutch. Mangled up the compressor clutch coil as well. The actual pulley, snapped off the bearing part. Pulley was only held on by the center bolt on the clutch hub. So, long story short, the compressor is locked up. Have to replace it.
This guy tells me he cannot do it, because to remove the compressor ,the motor has to be unbolted from the motor mounts and raised. Is this true? I have a service manual, that does not say anything about that at all. It does indicate that the compressor has to be removed with the third bolt loosened but still in place.
Can I get some info on the removal of the AC compressor in this truck? The idler/tensioner pulley has already been removed. The fan shroud has been removed.
Ford 6.0L Power Stroke Diesel :: Compressor Spin Even If AC Or Heat Isn't On?
Ok so I have another issue. This is one of three right now. Had the truck flat bedded home due to a seized rear caliper. Carrier bearing is causing vibration, will replace that this weekend. My question is does the ac compressor spin even if the ac or heat isn't on? Mine wasn't spinning today when the truck was idling. Should it always spin and just not be "engaged " my ect was quite high too but I thought that was due to the locked up brake.

View 14 RepliesFord A/C :: Compressor Was Cycling And It Never Engaged
My 2001 Expedition 5.4L sat for 2+ years and due to a new child, I put it back on the road late last fall. Last week, we had our 1st "must use AC" day and it didn't work.
I listened to see if the compressor was cycling and it never engaged. I picked up a gauge and r134a kit.
Outside temp was about 60F, I think my therm was showing 57F to be exact. When I checked the low side pressure with the engine off, the gauge reading was below 15. It made sense that the compressor wouldn't start at the pressure. I put in about a 1/2 can with the motor running A/C on max and it was showing 40, but still no compressor cycling. I then shut the motor down, let it sit for about 3 mins and restarted. This time, the compressor started to cycle, it was cycling quickly though, I'd say about every 3 seconds.
With the compressor cycling, the pressure would jump from 17 to 40. With the motor off, it would read 50. Still no cold air. I put in about 14oz of R134a.
I guess what I need to know is if I should I keep adding R134a until it stabilizes around 40, even when the compressor is cycling? Also, where should the static pressure be? It's sitting at 50 now. I've been told it should be around 80, but I'm thinking that might be dependent on outside temp.
BTW, I'm now thinking that the reason that I'm not getting cold air and the compressor keeps cycling is because I need to add a lot more R-134a. I think when the compressor starts and draws coolant, the low side pressure drops to low, causing the compressor to turn off. When the compressor cycles off, it sees the low side pressure at 40 and starts it up again causing the coolant draw and low side pressure to drop to low again. Am I right on this thought? It looks like I'll need to add another can to get the pressure to stay above 22 when the compressor is running.
One other thing... How much R-134a the system takes? I need to know because I have access to a vacuum.
Ford 6.0L Power Stroke Diesel :: 2005 F350 - Compressor Damaged?
I recently picked up a 2005 F350 6.0. I got it cheap with a plugged oil cooler, and went in planning to do studs, gaskets, and all the Ford updates just to have it out of the way. When taking it apart, I quickly noticed that the compressor was damaged. Looks to me like some foreign object(s) entered the turbo, would bounce off the wheel, impact the cover, and repeat.
Engine seemed to run great. Turbo spooled quickly and while I wasn't paying close attention, I'd glance when accelerating and it'd be in the neighborhood of 27 PSI. Engine cranks evenly and starts well, so there's no obvious engine damage. I'll inspect the bores closely with the heads off.
So my main question: Assuming no damage elsewhere, Do I need just a wheel? There is some pitting and high spots on the cover, but could it be carefully worked down with the cover removed? Do I just need to get a wheel and a cover? Or just a whole new turbo? Looking for a budget-friendly option to remedy this properly.

View 14 RepliesFord 6.0L Power Stroke Diesel :: Oil Leak Under Turbo Compressor Housing
I have a small oil leak that is showing up under my turbo compressor housing. It's starting to show a little in the valley. Not a big leak, just not sure were the source is and would like you opinions and recommendations. I have been cleaning it up every few days, drive it then use a mirror and rag to try and locate the source.
Here are some pics, I hope I took some that are good enough. Unfortunately I cleaned up the oil before the pics, but I circled and marked the location.
Concerned about the turbo, but I don't understand this leak since it's not coming from the center section. The turbo drain pipe is new and it does not seem to be coming from there. The leak is not enough to show a change on the dipstick the last 3-4,000 miles as far as I can tell.
Ford 6.7L Power Stroke Diesel :: Compressor Kept Running For A Few Seconds After Truck Was Off
Strange thing happened yesterday and again today. I have my compressor hooked up to up fitter #3 ,turned it on yesterday to fill the tank back up to 120psi. Before it filled up i shut the truck off to fuel up..but the compressor kept running for a few seconds after the truck was off. and today doing some running around the compressor turned on out of the blue when i was driving..but the switch was off.
The shut off switch (on the compressor itself) turns it on at around 90psi and shuts off at 120, but the thing filled my tank to 180 before i noticed it was on, pulled over to shut the truck off and again it ran for 10-15 seconds after the truck was off. I'm pretty confused. maybe it has something to do with the build up of snow under the truck, we just got 16" two days ago. but still when the up fitter is off shouldn't that cut the power from the accessory hooked up to it?
Ford 6.7L Power Stroke Diesel :: Loud Electrical Pop With Air Compressor Relay
Every time my air compressor would shut off I got a loud annoying pop through the radio. Even if the radio was off I would still get the pop. I knew it couldn't be good for all the electronics in the truck so I tried a mod.
Diodes across the relay signal terminals need to be installed in performance carts to protect the electronics. I put one of these diodes on my truck this week. 100% of the pop is gone.
I used this one : ACC-KIT-CSD-1
Ford F-150 (2009-2014) :: 2012 - AC Wasn't Blowing Cold Air / Possible Compressor Bad
I have a 2012 truck that the AC wasn't blowing cold air this summer so I took it in and they said nothing was wrong... Took back in and they replaced vent control... worked a little bit. Fall came and my windows fog up and really never clears up so I take it in and they said it is blowing hot air but I told them that isn't the problem but the moister in the cab is the problem. I feel I'm getting the run around.
