Ford 6.0L Power Stroke Diesel :: Max Oil Temps While Towing

Last year while towing my fifth wheel to the North Rim of the Grand Canyon my oil temp went to 260 degrees several times. The outside temps were 95 degrees at the start and it is a long steep climb with a heavy load. Each time I pulled over for a bit, as I couldn't remember at what temp that plastic thing inside the oil filter melted. Each time it cooled off fairly quickly but it really stressed me out. So how hot can the oil get. I am using Rotella T-6 and my temp different is only 12-15 unloaded. Could I allow 280 for 15 minutes or so?

Ford 6.7L Power Stroke Diesel :: Truck Temps While Towing In Hot Weather

I was towing the 5er (about 15000#), across Southern Mn and SD today going right into a 20-25 mph wind in upper 90 temps, saw 228 on the oil temp and 199 on the tranny temp. When tow need to see for warmest temps and at what point you start to get concerned...

Ford 6.0L Power Stroke Diesel :: High Coolant And Oil Temps?

New 6.0 owner having some issues. I have read just about everything I can find on the ECT/EOT problem.

208K on it, its been studded, running a full banks system. Factory size tires. Since buying it I have drained and flushed with distilled 4 times before new ELC coolant (system looks very clean, no debris found at all), T6 oil change and cleaned the air filter.

I am having a large delta on ECT and EOT. Here's some data from today's run. There is a lot of it. Readings from every minute.

Ambient Temp 118 today, took it for a run up the highway cruised north at 65 mph and back south at 75mph. I was driving on Saturday at 75mph and got the wrench light for excessive delta with 232 degree EOT.

45mph on the way to the Freeway- ECT 195.8, EOT 213.5

65mph after accelerating lightly- ECT 197.6, EOT 216.4

10 miles later, flat 65mph cruise set, it maintained a reasonable temp hold and reached max of ECT 199.4, EOT 218.7

After 2 minutes of coasting down off-ramp and sitting at a light- ECT 195.8, EOT 213.5

after reaching 75MPH moderately- ECT 201.2, EOT 216.5

1 mile later, holding 75mph- ECT 204.8, EOT 220.2

2 miles at 75mph- ECT 204.8, EOT 224.6

3 miles at 75mph- ECT 204.8, EOT 225.2

4 miles at 75mph- ECT 204.8, EOT 226.4

5 miles at 75mph- ECT 204.8, EOT 227.3

6 miles at 75mph- ECT 204.8, EOT 228.2

7 miles at 75mph- ECT 206.6, EOT 228.5

8 miles at 75mph - ECT 208.4, EOT 231.0

At this point I dropped cruised and coasted to the next exit, a mile down.

After coasting to exit and sitting for a minute- ECT 201.2, EOT 221.0

After a mile at 45mph- ECT 203.0, EOT 221.6

2 miles at 45mph, lightly on throttle- ECT 204.8, EOT 221.0

After idling stopped for a few minutes- ECT 195.8, EOT 213.8

Driving again lightly at 45mph- ECT 203.0, EOT 211.5

Am I just ignoring the obvious oil cooler issue or is this a water pump, etc? I changed out the thermostat again for another motorcraft unit after Saturdays hot run. I swear it did not run this hot when I got it... but I question if they were running nearly 100% water in the system. What EGR cooler there is, if there is a way to tell without disassembly?

Ford 6.0L Power Stroke Diesel :: Coolant Temps Seem High

It's been pretty smooth sailing since I installed my BPD oil cooler a couple months ago, oil temps are great now. However, in the last month or so, since the outside temps have gotten hot, I'm noticing that my coolant temps seem to be a little higher than they should. I put a new Ford thermostat in it back in the fall when I flushed the coolant system and refilled with EC1 coolant. The temps I'm seeing range from 206 up to 222 and I have seen as high as 230 when I was going up a long grade on a hot day. This is not towing.

The fan does kick on like it should, or at least I think its working properly. When the temp gets to 210-212 I can hear the fan a little, when the temp gets to 219 I can really hear the fan. It usually cools it back down pretty quick unless I'm headed up a long grade. Am I wrong in thinking these temps are too high for a 192 degree stat? My worst fear of course is head gaskets even though I don't have any other HG symptoms. No coolant loss, no puking. What other things should I check first? A new thermostat would be easy enough but I don't know if that would be the issue or not.

Ford 6.0L Power Stroke Diesel :: 2006 F350 - Loss Of Power When Towing Up Grades

My dad recently bought 2006 6.0. He has had it about 2 and half months. Has the egr delete kit installed. The truck has ran great. Up until Wednesday the 3rd. My dad headed to Ut to pick up our new quads. While heading up a small grade with empty trailer in tow. Truck went to limp mode, fan kicked on, orange wrench came on on dash board. He pulled over let her cool down turned her off.

Checked fluids Then started her back up and she was fine. That has happened 3 times. Now he is on his way back (tow haul mode turned on) and it is doing it again. She hasn't went into limp mode yet. As soon as the fan kicks in my dad pulls over immediately and puts it in park. And lets her cool down checks fluids. This issue only happens mid way up a grade. So my question is...... What is causing this? How do we fix her and make her a happy truck again.

Ford 6.7L Power Stroke Diesel :: 2011 F350 - Transmission Temps Hot / Antifreeze Coming Out The Cap On Degas Bottle

Just bought a used 2011 ford f350 with the 6.7 diesel engine. Coming from a 7.3 1999 f350 with 330,000 miles, still going good. Took a 1000 mile trip on the 11 truck with out pulling anything did good. Hooked my enclosed trailer to it did a trip of 900 down and 900 back. Transmission temps were staying around the 250f, almost in yellow on gauge. Highest it went was 255f. Light never came on. Yesterday on trip without trailer was staying at 230f on trans temp. This is the first concern.

Second concern, had antifreeze coming out the cap on the degas bottle. Rolled over the hood and hit the drivers side windshield. Stopped un did the cap, it hissed. Put 2 quarts of antifreeze in drove on, this at 300 miles of trip. Primary water pump went out, half way there, at about 550 miles of trip. On trip back, about 1600 miles of trip, antifreeze was on windshield again. Undid cap, hissed, did not need to add any to it. Drove on no problems since. Have bought a new cap and installed.

Transmission doesn't want to shift right when its cold. First starting out. When it warms up shifts great. That's third problem.

Ford 6.0L Power Stroke Diesel :: 2007 F350 Running Extremely Rich When Accelerating From A Stop

I have a completely stock 2007 F350 turbo diesel with 98000 miles that i just bought . When accelerating from a stop, it runs so rich that it will barely move and it accelerates very slowly . It burbles excessively and spews black smoke . It slowly builds rpm . As it builds rpm it runs slightly better and the black smoke turns into a medium gray the faster it goes . It takes around 20 seconds to reach 3000 rpm on level ground with the accelerator pedal half way down . Once it reaches 3000 rpm, it runs fine and hauls a_s but looks like it still smokes a little.

The temp gauge stays right in the middle and it does not run hot . It starts and idles fine. The check engine light is on but i have not read the codes yet and can't do that until monday. I have read that it could be an injector that is stuck open but do not know how to check for that. I am a vintage car mechanic and engineer but I know zero about newer computer vehicles and very little about diesels.

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.

Also fan seems to be work properly I monitor fan speed etc., and tft on my scangauge.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Lag Off Idle For About A Second Every Once In A While

Well, after getting the bed back on my '05 F350, I have been driving it on the road for a few days, but now I have a new problem.

Every once in awhile I get lag off idle for about a second, then the turbo spools and everything is fine. Other times, I step on the accelerator a bit from a stop, and the truck acts like its going to die for a moment, a puff of black smoke, and then the turbo spools and all is back to normal. It a combination of these two problems happens about 3-5 times out of 50 stops a day.

I have a scanguage and everything looks normal and I never get any codes when I check.

2005 F 350 6.0

124000 miles. Drove the truck on a long road trip Saturday ran great. Didn't touch it Sunday. Went out Monday morning and it wouldn't start I noticed the fuel gauge said empty and the low fuel light was on. I knew there was plenty of diesel still in the tank but I still went and bought 5 gal and dumped in it fuel gauge then read over half full but still won't start. A buddy who's a mechanic swung by sprayed starter fluid in it fired right up then died he said I need a new fuel pump. I have been reading the forums. I just want to make sure is he right?

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Hard / No Start - Low Power

Don't know where to start so I'll ramble!

2005 f350 with the 6.0. Crew Cab, 8' box, 4x4 with DRW. I use it only take the boat to the launch 5 minutes away once in a while and to pull car trailers every other week. Majority of driving is on the highway and average trip is about 300 miles. Low power and now no start.

No codes. I do have a scan Gauge and can provide data.

Was running this week, but has had a lack of power for some time. I had put 2 new injectors in last summer. Also updated dummy and stand pipes. Blue spring. Also new IPR at the time.

Ficm board was replaced in March.

New injector harness last year. New Glow plug harness last year.

Coolant level is fine and none being lost.

CAC hoses appear fine, no cracks.

No boost. But newer MAP sensor, hose not cracked or plugged and nipple on intake is clear. Put the MAP sensor last year and it didn't make a difference.

Turbo was rebuilt 2 years ago.

IPR has to hit close to 80 before boost hits 12-15. But it takes a while to get there.

Now won't start.

Yesterday am it was about 30 farenheit and no start. Last year would start no problem.

Batteries are fine. tested.

Engine fires within 3 seconds, but doesn't want to run.

ICP is above 500. climbs as I turn over.

Fires only in first few seconds and then nothing while I keep cranking it. it is cranking fast enough though.

Now...I see IPR will hit 84.7% and then 14.8%. Not good!

When running it sits in between.

FICm voltage is 48.5 key one and 47.5 when cranking.

Wondering if possibly IPR screen is plugged? Or would CKS or CPS cause issues? I recall reading about pulling one of them and cleaning rust off of it? Also...should mention, no EGR reading on scan gauge..never was either. I had checked and cleaned egr valve before. it was clean when I pulled it and not sticking.

Intake had been cleaned 2years ago. Also, on occasion, while pulling up hill, I would get power! Black smoke and it would race up a hill like it's supposed. Then it would go back to no power.

Also...if I pull the MAP hose from the intake nipple, should I feel suction from the intake? There doesn't appear to be any air coming or going from the nipple.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - No Power To Move

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didn't have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines, harness, pump, sending unit , tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.

So I took that stuff to the garage had them swap it out and now they said come get the truck they won't work on it anymore that now it needs 3 injectors and they won't touch it with aftermarket fuel system on it. So i go to drive it home and it starts but runs rough and u can hold it to the floor and it won't budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now.
