Ford 6.0L Power Stroke Diesel :: 2007 F250 - Max Oil And Coolant Temps?
Jul 11, 2016
I have a 2007 F250 with the 6.0. Towing up a long hill my truck went into limp mode. I didn't have gauges at the time so I didn't know what my temps were. I now have gauges. I know that the coolant and Oil temps should not be more than 10-15* apart, but what is the max temp that oil should EVER get towing up a steep and long hill? Also, what is the max temp that coolant should EVER get towing up a steep and long hill?

I have a new(and flushed) oil cooler and new thermostat and my coolant and oil temps never go above 190. They are always within 3 degrees at most but is this actually losing fuel mileage? I thought these were good numbers, could be wrong though.

I am looking for some insight on an issue before I lose sleep over head gaskets. Headed out today in the truck, and no heat whatsoever. Im thinking maybe a vacuum issue, but 4wd (esof) and all vents move just fine. About 10 miles in I over heated at 236 ect. After cracking the coolant cap there was no coolant. I havent actively monitored it but last i checked was fine.
The exhaust does not smell sweet and I see no puddles or any evidence of coolant splatter before today when i refilled it today. There was some tonight but im thinking that's from me spilling some today. Egr is also blocked off. I need the truck soon for plowing so need this resolved asap.

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?

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.

Took a trip today that was 3 hours there and 3 hours back. Truck ran normal on the way there (eot about 202 and ect about 196-198), but on the way back truck ran a little hotter than normal (ect as high as 214 eot stayed within 2-3* plus or minus ect). Fan did kick on every time I hit ect of 212 and would drop it down to 196-198 and oil temp would drop at the same rate.
Truck is stock 190k miles with a bulletproof egr cooler and coolant filter. Oil cooler probably has about 20k on it. (4th one on this truck- since I like changing them out as much as the rest of us). I checked coolant level when I got home and I might've added a pint to get to bottom of sticker. I'm not sure it wasn't a pint low when I did last flush and cooler replacement.
No puking and I can't find any leaks. I pulled egr valve and no moisture in manifold just a worm out o ring that'll I'll replace. I can't find any leaks. Where to check that I haven't? I don't feel like I'm losing coolant because I wasn't really low. My fan never failed to kick on when I hit 212 or stopped at a red light. No moisture in manifold so I'm not thinking losing coolant due to head gasket. Maybe radiator looks ok but tomorrow I will blow out any bugs to make sure.

I'm trying to chase down a couple of issues and I need to be able to monitor the coolant (and oil) temps. I've downloaded the manual and the specific 6.0 X Gauge commands but don't see the coolant temps listed.

I have a O6 F250. Egr delete and a new oil cooler 20k ago. I have been dealing with missing coolant for about 6 months. A little here or there but it has gotten really bad the last few weeks. My last attempt was to replace the degas cap. Stopped the missing coolant for a 30 mile trip. Just to clarify it had gotten to the point I was adding one gallon per 20 miles. Needless to say I was thrilled. Next morning I came out to find coolant under the truck. Plastic Y under degass, so I replaced it. 25 miles and none missing. Next morning fluid under the truck. Now it's the egr hose.
Replaced it with a gates hose and new clamps. Fill it up with coolant go inside and its leaking in the same location. Its a pure pleasure to undertake. So I assume these leaks weren't previously leaking because the degass cap wasn't pressurizing the system. That being said the leak is on the oil cooler side of the egr hose. The snap lock fitting that was on the original housing spins around. Should that locking mechanism be removed before the hose is secured and clamped? This is the only thing I can come up with as the culprit. I have searched the information on the site but can't find any mention of it needing to be removed. The clamps are the right width and everything is seated.

I've been MIA for a while. 2006 F250 just hit 83k miles. My coolant must be puking out of the degas tank. White residue all over degas and drivers side engine bay. I had my mechanic buddy pressure test coolant system for several hours and he said there weren't any leaks. He told me to replace the degas cap for now. Didn't solve the problem. Temps have always been fine. Never found drops or a puddle of coolant. Even when the truck has sat overnight for over 8 hours, there is still a bunch of pressure built up when cap is removed.

I spotted a leak last nite on my 6.0. It is coolant, running down the right rear on 2 metal lines that go to the trans I think. It was dark and 24 degrees so I did not spend too much time looking. Shut the mother down til I could research. 2004 250, 6.0 FX4x4, stock. Coolant was changed to green by previous owner. Bought it 4 months ago. 187,000 miles.....

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?

Have been working on military diesels for years. I have a 2007 Ford F-250 6.0. I am currently waiting for a new oil cooler as I have oil coming from my coolant reservoir and no coolant in my crank. My question is I have been having my engine light coming on and off intermittently since deleting my EGR cooler.

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...

My friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.

I've got a no crank issue this morning. This truck has done this randomly off and on, mainly during colder temps, but normally if I hold the key in the start position for a few seconds it will crank. This morning, no such luck. Batteries are good, everything has power, I can hear the starter relay clicking when I turn the key to start but it won't turn over. It never does this during warm weather. It got down in the low 40s last night and it's rearing it's ugly head this morning. The only code is the P0341, camshaft position sensor, but I don't know if that would be the cause of this or not. It's a starter issue or the CPS?

This weekend while towing a light load I noticed my FWT and EOT starting to climb rapidly, EOT reached 260 FWT I think about 240. I exited the interstate to find I had a busted radiator hose. I replaced the hose and filled the system with distilled water, but didn't add antifreeze at this time. The system wasn't completely empty.
I noticed once back on the road my EOT seemed to be higher than normal but FWT seemed to be normal. Could the lack of antifreeze cause a greater delta between FWT and EOT? I have seen articles which state do not use Ford Premium Gold Coolant, but to use CAT EL-1 coolant instead. Which should I use?

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.

On my 2005 F350 Super duty 6.0 Power Stroke Diesel I have extremely high oil temps when towing and also have a warm start problem. I need to tackle both these problems at the same time but I am struggling to find the correct (and still affordable) parts for this. My local parts store and Ford dealer are way over priced.
First, I need an oil cooler (truck has an EGR delete so no EGR cooler).
Second, I want to replace all the seals in the high pressure oil system and replace the HPOP elbow.(Already replaced IPR)
Third, I would like to do the Blue Spring update as well while I am in there.
Looking for part numbers or kits numbers. I usually do all my own research but right now I am way too swamped at work and home to find these parts.

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?

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.

The lights are on on the switches themselves, I used the red pass through wire under the hood and then connected it to the Orange w/ blue tracer upfitter wire( I think #4 switch) and it has no power. Changed the fuse and still nothing??
