Loss of coolant! I have a 2003 6.0 diesel with 200,000 miles. I put in a new oil cooler and ipr egr delete two years ago also flush the system and added a coolant filter. I filed it back up with the red antifreeze. Now the problem I have never lost any coolant since then and my deltas are about 5 degrees. But the other day I pulled a heavy load the first one since I did the repairs (coolant got up to 220 degrees and would drop back down) when I got home the coolant tank was about a inch low. I let the truck sit about 3 hours and checked it again and it was back at the full mark. Drove it the next day and it's back low about a inch, Any clue what's going on.

First off I have a 2001 7.3 with 294000 miles. While pulling my camper after it gets warm it puts out a very loud whistle it seems to happen when the fan clutch kicks in it does not sound like a belt squeal it almost sounds like it's coming from the turbo area. The engine seems to Surge while this is going on but the RPM gauge doesn't dictate that it almost sounds like it's the fan clutch surging. I took a short video of it while it was doing it ...

New to the 6 liter powerstroke recently upgraded from my 7.3. Recently this odd whistle sound started and I can't quite seem to fogure out the cause. At first it only happened if I was going 70 mph and now it will do it anytime it builds more than 15lbs of boost. I tried tightening some clamps and stuff but that did nothing.
View 14 RepliesFord 6.7L Power Stroke Diesel :: 2015 - Shaking Under Slight Load Due To A Small Incline And Loud Diesel Sound
So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
Ford 6.0L Power Stroke Diesel :: Slight Whistle / Squeal When Boosting And When Letting Off On Pedal
Are they known to cause any noise? VGT Solenoid.
I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.
It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...
Ford 6.0L Power Stroke Diesel :: High Pitch Whistle Noise From Turbo / Exhaust Area
For a while now, I have been hearing a very high pitch whistle noise from the turbo/exhaust area. Everybody told me it was an exhaust leak, but I never could pin point the leak. While I was under the truck last weekend I found the flex joint on the passenger side up pipe was broken a leaking.
I ordered a Dorman replacement pipe that comes with a new gasket and hardware.
I will be the first to admit, I am not a fan of Dorman parts... BUT, this pipe is really nice. It looks identical to the pipe being sold on Dieselsite.com, it doesn't have the scoop inside to direct exhaust gas to the EGR cooler and it comes with all the mounting hardware.

Once I got the turbo down pipe out of the way and soaked the bolts with penetrating oil, I had the broken up pipe off in 30 minutes.
Ford 6.7L Power Stroke Diesel :: Regen While Towing Heavy With Low Soot Already?
Over the holiday weekend I towed my 13k# 5th wheel 180 miles to the campgrounds.
According to my Torque Pro app, soot was around mid 30% when I left home. Upon arrival it had passively dropped to single digits.
After driving unloaded a few times over the weekend, the soot level had gone back up to mid 30s.
While towing home it again had passively dropped back to 1.1% .......... then boom! A regen starts.
After 22 miles it completed and soot had dropped to -13.2%.
So towing heavy, passively burning soot off, exhaust temps in the 700-800 weren't good enough for the system.
It had to start a regen and boost tempts to the 1100-1200 range WHILE TOWING to basically burn off NOTHING.
Not to mention drop my already poor MPG to single digits.
Just venting about what appears to be unnecessary exposure to high temps and wasted fuel.
Ford 6.0L Power Stroke Diesel :: 2006 - No Power To Untrack Load?
I have a 2006 F350 Superduty hd 4x4 6.0 Diesel. When it begins to start pulling from a standstill, it will not build power to untrack the load. Once it gets going the turbo will build boost and pull fine. Checked Boots on tube from turbo to intercooler for possible leaks. Replaced tube from intercooler to intake. Made sure map sensor tube was clear of soot (none at all in there). Air Cleaner is in good shape. Im a little Frustrated.
View 7 RepliesFord 6.7L Power Stroke Diesel :: How Long To Idle A Hot Engine After Heavy Towing
Now that I have gotten my ScanGauge II to monitor all 4 egt sensor, I am wondering about temperatures while towing, especially how long to idle a hot engine after heavy towing.
I realize all 4 sensors are post turbo (and there is no chance I'm going to drill for an after market pre-turbo sensor). It seems the first one downstream will be the one to watch.
What temperature range we should look for before turning off the engine? IIRC, Ford recommends idling for 3 to 5 minutes, but watching the temp seems a bit more specific.
Ford 6.0L Power Stroke Diesel :: Knocking Sound / Heavy White Smoke
So I am owning my first diesel so I am still getting use to it. Shortly after I bought it, I had to make my 900 mile drive to work and it ran great. After being here for a week or so I noticed heavy white smoke bit thought it had to do with the -5- -10. And haven't seen the white smoke since the weather warmed up. Since then I have noticed a "knocking" sound that to me sounded like a rod that I didn't notice before. After reading through these forums, it sounds like I probably have a cracked injector. I have had no engine light or anything. So my question is, can an injector fail or be cracked without an engine light and can a code reader detect which one it is with no light on?

My 6.0 stalls out when under load above idle intermittently. When it stalls, if I release the gas pedal and tap it, it usually catches again but not always. ICP is strong and doesn't seem to waiver when it stalls. Engine runs much better when oil comes up to about 180. Oil / water temp spread about 5 degrees.
View 14 RepliesFord 6.0L Power Stroke Diesel :: Overheating When Pulling Load?
After replacing both heads with remanufactured heads from ford along with new egr and oil cooler a month ago, she still overheats when pulling a load. While normal driving and not towing, no problems. In the last 5,000 miles since work was done and while towing approx. 15,000 lbs (load and trailer weight) she got hot once, slowed down, temp retreated got home - she has not overheated since then pulling 4-5 loads over the next 2,500 miles. Today at about 75 degrees only 4 blocks after picking up a load at about 12,000 lbs she started getting hot again. After I let her cool down and got on the Freeway the temp went down, appears she's not staying cool in the city with a load on. With all the work and new parts I had installed, what the problem might be?

Yesterday I was coming back from town and as I was looking in p/s mirror changing lanes I noticed heavy white smoke. I only noticed this upon decel or coast. Once I rolled back into the throttle the white smoke would dimminish. I'm sure it was coolant from the smell. The truck (04 F250 CC 6.0) is now at the dealer for troubleshooting. I believe it to be a blown head gasket, but wouldn't that make it blow white smoke out the exhaust all the time? Maybe a cracked EGR cooler?

Just installed my SCT livewire TS. The truck runs good without a tune but it has egr delete so it had check engine light. So I put a performance tune with egr disabled so it cleared code. But I noticed at pretty heavy acceleration the fuel seems to cut out. Usually once boost builds. Does the same with the street tune.
View 5 RepliesFord 6.0L Power Stroke Diesel :: Heavy Black Smoke When Taking Off From A Dead Stop
a little history here, about 2 years ago I got my first P401 so I changed the egr valve and it went away for a little while. Then I came back several months later and changed it again. along with the P401 I get heavy black smoke when taking off from a dead stop and after it gets a little speed it will run good. Here lately it seems I can only get 2 weeks to a month between cleaning the EGR valve.
Each time I clean it has a bb size piece of carbon stuck and is holding the valve open and there are several more under the EGR valve. each time I try to vacuum the carbon chunks out and clean everything as best I can. As of now I'm fed up with it and would like to do something to make it more reliable. would taking the intake off and cleaning completely and adding a EGR delete kit eliminate the carbon from building up?
Ford 6.7L Power Stroke Diesel :: Rear End Noise / Vibration When Under Load?
I ran about 500 miles today loaded up pretty good and noticed every bump I hit that was enough to rock the truck and trailer that there was a noise I've never heard before. It was like the difference between asphalt and concrete road surfaces, but was only present when the springs were sufficiently compressed. Temps were between -10 when I left to 10 or so above when I was destinated. Would that cause the noise?

2005 F250, 6.0, 60K miles, recently (within last 1K miles) had ARP studs, EGR delete and new oil cooler installed. Shortly after (5-6 weeks later) I noticed blue smoke under any load (taking off from red light, backing up) but not at idle or startup. Was using the "Performance" SCT canned tune after the stud install, but had the "65HP Tow" canned tune installed when I first noticed the smoke and now back to stock after noticed the smoke as a precaution. Everything else original except FICM, filters and batteries and use 5w40 Mobil 1 since new.

So pulling my trailer and 4x4 and the truck dies without any other symptoms. No check engine light all other electrical remains working. This happened 6 times this trip always while pulling a grade but only after the truck has been running for a few hours. Each time, no warning and once the truck has set for 5 to 10 minutes it start up like normal. The longer i let it set the longer I can run before it does it again. ICP is 550ish at idle, 200ish while cranking. Check the FICM before the trip and it was at 47.5 to 48.5v key on engine off and running. STC, stand pipes, dummy plugs, ball cups have all been done.
