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...
View 10 RepliesLast 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?
View 11 RepliesOn 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.
I was towing a fairly heavy trailer yesterday (around 10k) and laying into the throttle to gain some speed before a big hill when I completely lost power. It slowed me down to about 10 MPH.
I was able to drive home at very slow speeds and the only way to get over 10 MPH (only up to about 20MPH was to very lightly accelerate up to speed. Any hard acceleration and it cut me off to 10 MPH. No warning lights of any kind going off...
Truck has a Hypertech Max Energy programmer on stage 2.
2013 CCLB, 33,500 miles, stock emissions
While towing a 9000 pound trailer at interstate speeds (75 to 80 in Wyoming), when pulling a hill, the truck downshifts to 4th gear, boost is about 18psi, eng and transmission temps in the 230F range, EGTs around 500C or 935F. RPM increases normally to 3000 then the turbo gets very loud and boost drops to about 10psi. The truck shifts to 5th gear, noise decreases but is still present, shifts to 6th and noise goes to normal after a couple seconds and boost builds normally.
This just started today. I have about 8000 miles towing this trailer and never had this before. I have about 350 miles until I'm home so I'm headed back out. Will play around with manual mode and see what it does. I also took a video of the gauges while this happens. Audio is difficult to discern. I will try to get better audio and post when I get home.
I want test my fuel pressure. What is a good gauge or kit to buy? My truck has lost power towing and is now starting to miss a little. I'm wandering if i my problem is in the tank. Is there a good scan tool that would diagnose things too?
View 14 RepliesI 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.
View 1 RepliesI 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.
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?
View 14 RepliesTook 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'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?
View 4 RepliesI'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.
View 8 RepliesThis 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 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.
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.
View 14 RepliesI have an 06 F-250 with 122,000 miles. When driving empty at 70-75 mph the coolant temp runs 194-200 and the oil temp 5 to 10 degrees higher at the most. When I pull my travel trailer the coolant temperature will start to steadily climb then abruptly drop down under 200. I have seen the coolant temperature pass the oil temperature when this happens.
The last time I pulled the trailer I was driving at 60 mph and the coolant temperature climbed to 220 then dropped to 196. A few miles later it climbed to 230 then dropped to 200. While the temperature was climbing I slowed to about 45 mph. As it was dropping I accelerated and the temperature continued to drop.
I have flushed the cooling system, replaced the thermostat and cap with no improvement.
The pickup has an SCT tuner set to street 1 and I was told by the previous owner that the egr was deleted, but the stock egr cooler is in place. It is possible that a plug was put in. I pulled the egr valve and the carbon coating on it is gooey like it has been wet.
Just looking for comments on using the cruise control while towing? and what's the recommended weight for using the tow haul mode. The enclosed trailer I have is about 3300 lbs. taking it across the country empty. 2004 6 liter.
View 11 Replies2004 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?
View 14 RepliesI have a 2006 f250 bulletproofed for about 5 years now with no problems other than normal wear and tear. I had the factory water pump go out a couple months ago so I decided to go with the bulletproof diesel pump for piece of mind now I do tow anywhere from 8K-15K about once a week with custom Gearhead tunes using SCT.
While I was changing water pump, I ordered low temp thermostat figured it would work with towing temps even though they weren't that bad to begin with my deltas always around 10-128.. Now i am seeing signs of puking out degas bottle, I replaced cap seems to work a little the truck doesn't puke unloaded unless i really get down on it.
I noticed the other day while towing I was cruising with TC locked in at around 55 mph and i watched my EOT 210* and ECT 205*, the n ECT started climbing up followed by EOT then at ECT 222* fan came on ECT finally hit 234* and started dropping fast while EOT never got over 226*. ECT would level out at 188* go back up to 205* and stay there for awhile and do it all over again...
What is going on. I've talked to a could mechanics and they aren't confident its the HG..
