Ford 6.0L Power Stroke Diesel :: 2005 - Overheating While Towing?
I have a 05 6.0l that started over heating while towing recently. In 2012 i did egr delete, oil cooler, stc fitting, and coolant filter. I recently changed radiator and tstat think that was the problem due to small leak in radiator, but still towing about a 4-5k load temps rise to over heat while towing. What to look for next. Also fan seems to be work properly I monitor fan speed etc., and tft on my scangauge.

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?

While driving home last night my truck started to overheat, the temp jumped from where its been running at lately (around 210) to 240, I stopped and took it easy getting home. This morning I sprayed down the radiator to clean out any mud that may have gotten in it from field work at the office (its always going through some pretty deep stuff). It ran fine for about an hour then it started to over heat again, I got it home and did a complete radiator flush and then did a test drive. It still overheated so I decided to try something, I released the pressure in the system by unscrewing the cap partially and drove it around again, this time it didn't overheat, put the cap back on and the temp jumped right back up to 240.

I just bought a used 2007 f250 with the 6.0 power stroke. The truck has approx. 160,000 miles on it. He is having a issue with the truck overheating when it is cold out. When the air temp is above 30 degrees or so, he doesn't have a issue. So,my he overheating only occurs when driving down the highway in low temperatures. It can idle in the cold fine.
View 8 RepliesFord 6.0L Power Stroke Diesel :: Oil Temp Overheating But No Coolant Disappearing
The truck has been just terrific, mostly used for towing our travel trailer. Earlier this year i developed a leak and lost 3 quarts of oil before I caught it. I would think with 15 quarts in her this shouldn't have been too big a deal. However, I am now experiencing 10-15 degree swings between ECT and EOT. Before I give the particulars, yes, I have had three new thermostats, two Ford and one brand X.
Anyway, coolant temps are 184-200 depending upon load, terrain, etc. At the same time, oil temps run 205-230. There is no oil cooler to get plugged up. She's got 120K on the clock, doesn't burn oil, no disappearing coolant. I am concerned about blowing a head gasket or other serious damage at these temps, but don't have a clue where to start? Yes, the fan does come on, but still this seems plenty hot.
Ford 6.0L Power Stroke Diesel :: 2006 F550 - Overheating Going Uphill
I have a 2006 F550 mini bus, that I just had the head studs done, egr delete and air intake changed. Last night we took it out for a run to test it since we just installed a new fan clutch. We can here the fan kicking on and off. The problem is, we drove it say 60 miles, up and down a mountain, had no issues. We got out and ate for about an hour, and then drove it back the same way. This time on a slight upgrade my check gauges came on, and I seen the temp rising. I let off the fuel, and it dropped back down. So the rest of the way home I was easy on the fuel and made it back with out heating up again.
Today, we took it for a ride and at idle before we left the ECT was 172, and EOT 170, as we drove I watched the temps. Climbing up a fairly steep mountain, we were doing about 65mph, for about a 5 mile climb. During the climb my ECT was 201 and EOT 226, at the hottest point it was ECT 204 and the EOT was 226.
I am assuming it could be a possible water pump and or oil cooler. Reason I am thinking the water pump, is because after it over heated, I noticed if I let off the fuel quick after running I would hear a noise like a puffing sound. It was the coolant shooting out of the degas bottle. It did this several times when letting off the fuel quick, which I think was the pump was allowing the coolant to be pushed back in from the heat.
I already ordered a new pump, which if bad could also cause the oil not to cool as the pump is not pushing enough coolant? (Also I only lose coolant if it gets to hot)...
Ford 6.0L Power Stroke Diesel :: 2006 - Overheating - Water Pump Impeller Slipping?
have a 2006 f250 with the 6.0 Powerstroke diesel started overheating yesterday the ECT and EOTcheck fine with the scangauge always ran with in 8 degree's of each other. Thought maybe water pump impeller may have been slipping so it is new with no change. Fan kicks on like it should. Heater works good so don't think it is a thermostat.
View 13 RepliesFord 6.0L Power Stroke Diesel :: Clicking / Chirping Noise - Engine Start Overheating
I have used this forum to look up everything I've needed to since I bought my 05 F250 FX4 6.0 brand new. I was pulling our brand new camper in 100* heat. I began to hear a clicking from the truck from the engine compartment that would be right by the turbo. My engine started overheating, but I had no smoke (black or white). The engine cooled down after I was done climbing the hills, but I had feathering from by the air cleaner and the clicking/chirping was still present.
I pulled over to let the truck cool and checked my coolant reservoir. While pulling over, I lost accelerator pedal responsiveness. The turbo was also engaging a lot. I pulled over. Put the truck in park, but left it idling. As I was looking around under the hood, the truck died. I have not been able to start it. (This all happened Saturday). The truck is 20 miles from home, and I've been out tinkering every day. Here is what I know:
1) I have 48 volts to the FICM.
2) I have tried to start it early in the morning and in the evening when temperatures were low.
3) When I crank, I do get oil pressure from the instrument cluster.
4) The oil level is at the correct markings on the dip stick.
5) Using my scanguage II, I have verified an IPR reading of 14.8. As I crank, it goes up to 84.7. My ICP reading is all over the place. It always gets to above 500, yet it with the key off - engine off, I get a reading higher than zero. With the key-on I go from 300 to 500 and to over 1000 with out the think even hinting at starting.
6) I have oil in the oil filter housing.
7) I have fuel in the upper fuel filter housing bowl.
8)The batteries and alternator have all passed load testing.
9)I tried to start the truck with the ICP disconnected, and didn't have any luck.
10) I have no codes set or pending.
I am at a loss. I don't want to start throwing $$ at various parts.
Ford 6.0L Power Stroke Diesel :: 2005 F350 Engine Overheating / Battery Went Dead
I have not started my truck for some time (about 3 months) and the battery went dead. I recharged the battery and started her up. I then drove my truck about 5 miles and noticed that the water temp gauge was pegged to overheat...unbelievable! So of course I stopped the truck at the the nearest spot that had a water hose. The water was about 2-3 liters low as I could tell. This should not have caused the engine to overheat though. So what happened here. The engine ran ok back home but now I do not know what to do. Is it an electrical issue where the cooling system has a valve that is signaled electronically to open for the water to flow thru the system??

2004 F250 6.0 L. New head gaskets, ARP studs, new oil cooler, new water pump, all new hoses, new thermostat, 4" exhaust, EGR delete, new coolant bottle, radiator and cooling system flush, new injector seals and oil rail plugs all done at 98,000 miles. The truck is at 119,000 now and has been doing great since all the work. I have been frequently hauling very heavy loads and pulling cars on trailers and no problems. EOT has been staying about 7 degrees above ECT except on hill climbs. No coolant loss at all. Today suddenly while driving on the freeway (unloaded) the temps spiked. I pulled over when the ECT hit 240. Once cooled down I checked coolant level, hoses etc and since all was fine I took off again. Overheated again after about 5 miles. My understanding was that the Ford thermostat fails open if it fails. Do I have that wrong? Do I have a stuck thermostat? Some other problem?

So my 11' F350 is over heating when the engine RPM's are below about 1300 whether the truck is moving or not. If I let it idle for 2-5 minutes I can watch the temp gauge go to red and an engine over temp message appears. I noticed that if I rev the engine to > 1300 RPM it cools back down.
This appears to be a water pump going bad, any other thoughts? Are there instructions for changing the water pump here on the forum?
Ford 6.0L Power Stroke Diesel :: 2004 - After Start Up Rough Idle And Power Lag?
Have a 2004 f250 that is having issues. Once the truck is started the idle goes from normal to loud almost sounds like its going to stall. A few weeks back the same happened when i was on a red light. It choked almost to where it was going to die. I accelerated when light turned green and would not move at all. I had to literally use full throttle to get out the road at about 5 mph. I pulled in to a gas station and fueled up as i had a quarter of diesel left and it stopped the rough idle and power starvation once i started the truck up again. It sees like this time its getting more persistent... FML AND THESE 6.0 problems
View 9 RepliesFord 6.0L Power Stroke Diesel :: 2004 - Rough Idle - No Power?
I recently bought a 2004 6.0 extended cab truck. It has 223,000 miles on it and has been running great. Bought it here in Arkansas where I live and recently drove it to Texas and back after having just put some Hot Shot oil treatment cleaner in it. I ran it the 1000 miles as it suggests. Just the other day as it was hitting the 1000 mile mark the truck started to lunge/runaway and stalled. I finally got it back home and started looking into the issue. Based on what it was doing, (lunging/running away, and at idle in park random burst of rpms and then dying after doing it a few times), I started to do some research. Most of the answers I found claimed it was the IPR valve. I found that the IPR valve is supposed to, as claimed by some, be pulled and inspected every 100,000 miles are so and if need be replaced or the rebuild kit gotten for it. So I decided to just replace it as well as the oil, oil filter and fuel filters.
When replacing the IPR valve I noticed that it was original and that its screen was missing. I didn't have any problem moving the little piston in the center of the shaft with a small bolt however that doesn't really mean that it isn't bad. I tried a magnet to see if the screen was still in there and nothing came out. I did not try using a camera as I do not currently have one, to look inside the port to see if I saw it. After replacing the IPR valve with a brand new one and changing the oil I started the truck. It seemed to be running a little ruff so I let it warm up. Not one minute later the exact same thing started happening, lunging/running away (random increase and decrease in rpms), so I called it a night. The next morning I decided to change the fuel filters. No that it matters the order in which I did it, but I changed the top end filter first and the the one on the frame with the dealer recommended OEM filters as was the case with the oil. I did find in the filter on the frame that there was a small amount of sand and clay soil looking matter in the filter. I did clean out the filter housing as well.
After replacing the filters I started the truck to warm it up. I noticed that it was still running a little ruff but no random, lunging/running away (random increase and decrease in rpms). However after five minutes it started coming back. I finished letting the truck warm up and took it for a drive. Got it up to between 7-80mph for about 15 miles to try and see if I could "blow out" whatever may be in the fuel if that was even an issue I do not know. The truck seemed to get more power and run a little more smoothly so I stopped at my buddies house not to far from where I was and let it idle. No issues other than a little ruff idle. After about 10min I took off towards home doing similar speeds. I noticed at a little over 2000rpms that the truck was shaking a little but so I dropped the speed down. When I got home not more than one min after idling the same issue, lunging/running away (random increase and decrease in rpms), started happening again.
At this point I took back to the interwebs and came across a post that said the ICP might be bad and does cause this issue, lunging/running away (random increase and decrease in rpms). However I also noticed that this is a huge debate as to whether or not the ICP can cause this. Ford master mechanics say no and other mechanics say yes and round and round it goes. I decided to do the simple test many recommended which was to simply unplug the ICP and see if anything changes. Things did change. No more lunging/running away (random increase and decrease in rpms). Not more than two minutes after plugging it back in, allowing the computer to account for it now, the lunging/running away (random increase and decrease in rpms) came back. In the middle of it doing this I unplugged it and that went away. So needless to say I replaced the ICP and voila the lunging/running away (random increase and decrease in rpms) is gone but the ruff idle is still there along with a slight loss of power.
To answer some questions:
1. The oil and water are not mixing so I am almost positive that the heads are fine
2. The intercooler couplings are leaking a bit. I have ordered the new ones and will replace them as soon as they come in. Can this cause the issue?
3. I am blowing no white or black smoke except for when the lunging/running away (random increase and decrease in rpms) issue was present and the truck almost died. It would knock occasionally when it almost died and would send a slight puff of black smoke which I assume is a low or high fuel issue from the truck trying to die
4. I have not had the no start issue at all
5. I did not see any debris in the oil during the oil change
6. I didn't do the air test on the ICP port as I do not have the adapter.
7. The only code I got on the IBD II port was when I unplugged the ICP which was to be expected
8. I found no damaged wires
I am at the point where I am wanting to take it to ford to have them run a diagnostic on it but am wondering if there is anything else I need to be looking for. Here are a few questions I have.
1. Does this sound like a bad injector? (When I bought the truck it would sound like a misfire or ruff idle condition was present for about 5-15 seconds and then it would smooth out with no issues. It would run a little ruff if you tried to take off without letting it warm up, which I did once or twice and low rpms, but when it warmed up no issues were present).
2. Could this be the HPOP?
3. Could this be the FCIM? (The previous owner had replaced the FCIM not to long ago with one from Ford I believe. Said it cost him something like $700)
4. Could this be something clogging the oil screen under the manifold?
My final question right now is do any of you know where or what brand OBD II reader or software I can get for a decent price that will tell me the voltage of each injector and FCIM is without me having to go to Ford to get it looked at.
Ford 6.0L Power Stroke Diesel :: 2007 F250 - Rough Idle And Dies / No Power
My truck died on the way home the other night. After pulling over it started right up but died three more times on the way home. Changed fuel filters, cps sensor which wasn't bad when tested, checked fuel pressure (60 psi), cleaned egr valve, fcim has 48 volts, batteries have 12 volts. Tried unplugging egr valve and icp sensor. Truck will start with icp unplugged . Ipr, stand pipes and dummy plugs were replaced last year when I purchased truck. Truck will run in park fine no issues idled normal, builds rpms and boost. Put it in drive when it gets warm rough idle and dies but starts right back up evertime. When truck doesn't die it has no power.

I have a 2005 F-350 Lariat, FX4, CrewCab, with an 8ft Bed if any of that matters. Currently sitting at 191,000 miles and 4,500 Engine Hours I just started running into some issues that I cannot figure out. To start with here is a list of all the mods and prior maintenance that I've done to my truck over that last 6+ years that I've owned it.
I purchased the truck in 2010 and had no issues whatsoever for the first 3 years.....then it all started. While pulling a camper home from vacation "still bone stock" the truck overheated and by the time I realized it it was to late. I ended up blowing a head gasket cracking a head and blowing a hole in my coolant reservoir from the heat & compression of the engine in the coolant system. So to the shop it went.
All of this was done at the same time at just under 4,000 engine hours:
1) Both heads were sent out to be pressure tested "which is where the crack was found", so 1 replacement head and the other trued up and tested by the machine shop
2) All 8 injectors replaced with Airtex/Wells New/Reman
3) ARP Head Studs
4) BPD EGR Cooler
5) New Stock Coolant Reservoir
6) New Stock Oil Cooler
7) Motorcraft Coolant & Oil/Oil Filter Change
8) New Serpentine Belt
After getting the truck back I installed some upgrades that I had wanted but didn't want to do until I had head studs. 4" Turbo back Diamond Eye Performance exhaust, Bully Dog GT Tuner with an EGT Pyro, coolant changed to Caterpillar ELC, Sinister Diesel coolant filtration system, new Optima batteries "I hated them",
Forward a year with no problems I had a crank but no start. I ended up having a bad IPR. A buddy rebuilt the turbo since I had it out and it was leaking. He apparently did something wrong because it took its own life sometime after. So a brand new stock Garrett Turbo with a Wicked Wheel 2 & I changed the IPR "don't remember the brand." Also replaced the factory paper air filter with a cleanable one from AFE that fits in the factory cold air intake.
Little more time and I started to have some overheating issues again, luckily the Bully Dog was monitoring and I had alerts set up so I caught it way before it caused any serious damage. Turned out the fan clutch wasn't working. So I replaced the Water Pump with one from dieselsite.com that has a steel impeller, also replaced the computer controlled fan clutch with a 7.3L mechanical fan clutch and an adapter from BPD.
After that the batteries I hated were replaced. I installed Oddssey Extreme 950CCA ones, a new 185A alternator from FICMRepair.com as well as the complete battery wiring interconnect kit. Did the blue spring upgrade. Replaced my FICM with the BPD 6 phase at 54V setting. Also I changed my starter to an 6.4L Ultima one from O'Reily Auto to bring me up from that slow crank of the 6.0L at about 150RPM to the 225RPM of the 6.4L.
So now on to the current issue. This has happened in the last month and may be related to the issue. I had some small coolant leaks and wanted them fixed. Pressure tested the system & found the radiator and timing cover gasket leaking. I installed a new stock radiator and lower radiator hose. Had the shop do the gasket and a serpentine belt due to cleaners being all over it. During replacement of the timing cover gasket my mechanic found that the LPOP gears had some damage as if something had be in there at one time. Not sever damage just minor. LPOP replaced with brand new one from Ford.
After I got the truck back it was fine for 2 weeks, no leaks or any problems whatsoever. Then I noticed a hesitation as I was leaving work at idle. You could see the RPM's moving up and down by about 50 as it sat there at idle. It got really bad and eventually stalled on me. It fired right back up and ran fine after. I was thinking water in the fuel or just maybe old fuel because it was kinda old and I was at 1/4 of a tank. I went and filled up and it ran great all the way home. Day or so later same thing. At idle you can see the RPM fluctuating and while driving it feels like it has no power at times then it goes away and runs fine. So I changed both fuel filter with Motorcraft ones and put in a new oil filter. It is the Wix brand but I've be running it for years with no issues, one was also in it way before this issues started. The oil has about 2,000 miles on it currently. I verified fuel pressure at idle to be at 70PSI. I tried unplugging the ICP at idle with no change in the hesitation. So I plugged in my SG2 and started to see if I could see anything out of the ordinary.
OAT - 60 Degrees F
KOEO Engine Cold - FMP - 54.5V, ICV - 0.25V, ICP - 0, IPR - 14.9
KOER Engine Warm - FMP - 54.5V, ICV - 0.82V, ICP - 576, IPR - 23.5
Cruise at 40MPH - FMP - 54.5V, ICV - 1.14V, ICP - 965, IPR - 32.9
Cruise at 50MPH - FMP - 54.5V, ICV - 1.42V, ICP - 1,190, IPR - 38.0
Cruise at 60MPH - FMP - 54.5V, ICV - 1.27V, ICP - 1,143, IPR - 37.2
While driving this issue comes and goes very randomly. The only parameter I notice changing alot is the IPR. It jumps around a lot and sometimes it will go to 85. I know that this isn't a good thing so I am going to change the IPR later today or tomorrow. I already had a brand new Motorcraft one to put in, plus at the very least I want to look at the screen. I had read somewhere that there could be air in the oil system and that if you run at a high RPM it can remove this air. I never seen any bubbles or anything on the dipstick. My brother ran the truck for me at 3,000RPM for 5 minutes. No hesitation during the test but he didn't have the SG2 plugged in so I don't know the parameters during the test. I thought that it worked but then it came back after a few miles of driving. The above parameters are from this mornings drive home from work.
Ford 6.7L Power Stroke Diesel :: 2011 - Rough Idle - Surging And Loss Of Power?
I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...
Ford 6.0L Power Stroke Diesel :: 2005 - Rough Idle - No Power - Black Smoke?
05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.
