My Fan Clutch seems to come on quite often when its not needed. Mostly when towing. I don't have any live monitoring system on my 05 excursion. no codes. I did recently replaced svt sensor and radiator was found with a leak replaced that. still having that problem?

View 5 RepliesThe 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?
View 12 RepliesI'm hearing a plane type sound on my 2004 f-250 6.0 and i also noticed the temp gauge needle went up but still in normal range and then went back to the middle range when slowing down or parked. I had a combustion test done and a leak test was done and all passed. The reservoir tank had a leak and changed that before all the test were done. The mechanic did various run test and it didn't over heat but it did when i got it back. My guess is that the fan clutch is out but not sure. An AutoZone guy came out and looked at the fan clutch and asked me to turn it on and hit the gas and then shut it off. He noticed that the fan clutch kept turning fast and he said it's not supposed to do that.
View 8 Replies My Edge is reading "PO528: Fan Speed Sensor Circ No Signal". When I'm pulling a large 5th wheel up a 4% hill by the time I hit the top (if I don't slow down)warning beeps are gong off and my ECT is at 240. I can hear the fan come in at 215 and it stays in all the way up in temperature.
All the posts say c/o the fan clutch. While that may fix the fault signal, would it do anything for the temp situation. If the fan is locked in it seems like a lot of money just to clear the fault. Or......is the fan still slipping but sounding like it's working? This my be not related but I did notice that as the temp rises the AC starts not working. By the time I reach the top of the hill it is blowing hot. As we go down the other side and ECT comes down, it starts cooling.
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
I have a 2003 6.0 and I got a scan gauge recently to monitor the fan speed rpm's.
When the engine is running at 2500 rpms the fan speed is only at around 350-400 rpm's.
I did have a code for IAT 2 circuit high I think I read that the egr is disabled when the iat 2 sensor is getting more than 4.8 volts.
Can a bad iat 2 sensor, egr valve or icp sensor cause the fan not to function properly?
06 6.0 fan clutch stuck in engaged position. So I changed the fan clutch it doesn't stay engaged anymore. comes on during startup and gives the appearance that the batteries are dying. Stays on for about 10 minutes when first driving then goes off. If I run ac it comes on at every light and it doesn't matter what engine coolant temp or oil temp and they are all within 6 degrees of each other. I'm thinking maybe the AC is a issue or bad sensor somewhere. No codes everything seems to be functioning. When I say comes on it's on high speed roaring.
View 14 RepliesI have a 04 F250 6.0L ,The center bolt that holds the a/c clutch to the compressor. I'm assuming that bolt needs to be tight, correct? Mine was loose when I looked at it last night. My a/c squeals for a while trying to engage. Also, is that bolt right or left hand threads? Can that clutch be replaced without removing the compressor?
View 9 RepliesWhat EOT temp should the fan clutch kick on at? I've never heard it kick on until a recent trip. It seems to go on about 228 degrees EOT and keeps the EOT below about 232 degrees.
At slow speeds I've found that the trans will heat up to this temp too. I assume because the radiator cooler is at that temp an there's not enough air flow for the air cooler to cool it down much?
Odd question, but the a/c clutch has always engaged randomly even though the a/c is not on and even now when the heat is on. Is this normal?
View 7 RepliesStarted today. 2004 with 235k miles. Owned for last 10k miles. Engine was recently studded, has egr delete and ccv bypass. Runs and starts fine. New Ford oil cooler too. Checked for codes. None for misfires, perdel are reading 0.
If it sits, on start up clear exhaust, as it warms, more blue smoke. Smells like oil not diesel.
Researched before asking and found leaking turbo seals can cause this. So we pulled the intercooler tube in front of the engine going to the intake expecting to find oil residue. Nice and dry. Was this the correct one to look at?
When we got the truck we had the dealer do a relative compression test and was within limits, it did need 1 injector that we replaced. What would be the next logical place to look?
Couple more points:
- Just changed oil last week, checked today, it was slightly over full.
- Coolant is fresh and has not changed level since we got it.
- Pulled fuel filter to see if any oil, but it was nice and clean.
I filled up at the same fuel station I've filled up at for 6 months, never had a problem. I just bought a 6 liter and put some injector cleaner in on the last fill up. Ever since then, it's been running really rough and missing when cold, and even when it's warm if I really lay into it, it'll pop and sputter. The fuel in water lights been on since I bought it. I think I have a bad sensor, because it was running fine until I put that cleaner in. Since its been running rough I put in new fuel filters and drained the fuel water separator, which only had fuel in it. I don't really know what it could be, but I'm 99% sure it's an injector issue since it started only after I put fuel treatment in.
View 8 RepliesIt only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.

On my 2012 F250 with 19k miles I have NEVER been able to fill tank with more than 22.4 gallons of diesel fuel. That was the day I ran out of diesel going to fill up thinking I had 26 gallons. Once the light comes on I'm filling up, I have every tank fill DOCUMENTED with (date/cost/gals/trip/$per gal).
Talked to local dealer Raleigh, NC , their explanation was fuel pickup was raised to prevent contaminates from getting into injectors. They advertise 26 gallons, should be able to access 26 gallons.
I've topped up the DEF and the warning is still showing that I'll have reduced engine power within 45kms.
Its weird, just yesterday it showed 550kms to empty so I added one full container, all day it kept showing less and less kms' til empty. Warning lights and bells etc.
This evening topped it completely and still shows. Is there a way to reset it without having to stop at the service dept.
Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.
Purchased 2011 3 weeks ago. Due to not paying attention, put gas in diesel. Had tank dropped and drained but after reassembly, fuel gauge inop. When turn ignition switch on, get normal sweep of all dash gauges but fuel gauge does not read. 2nd tech says sender okay, must be gauge. Dealer ssays if it sweeps, it isn't the gauge. 011 F250 6.7L.....
View 7 RepliesIs this the sign of a bad fan clutch? I can spin it by hand,and it goes round and round.Can I drive it like this until I replace it? I am only driving 30 miles round trip at night, not towing and outside temperature is usually about 100 degrees.
View 6 RepliesIts freaking hot! Only getting about 65 degrees out of the vents at best. If I start up and let idle the a/c clutch goes on and off but not after i rev up the engine or drive a little ways . plenty of freon, and the air gap is tight with .020 and .021 feeler gauge. Should I still pull one of the shims? or is it something else? Last summer the truck was like a meat locker. I did have to add some freon about 6 weeks ago but seems to be holding ok...
View 14 RepliesMy truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.
