Ford 6.0L Power Stroke Diesel :: High Pitched Squeal - Coolant Temp At About 180 Degrees
Jan 4, 2015
I have a 2006 350. When I am pulling my camp trailer (about 12,500 lbs) up a grade I hear a fan or blower turn on and I get a high pitched squeal. It will also have a beep and my in dash display will say high engine temp. I have a bullydog pmt programmer (i tow with it in stock mode) the display will show my coolant temp at about 180 degrees. If I pull over and let it idle for about 2 minutes the warning clears and the temp gauge returns to normal. the display reads about 180 degrees the whole time this goes on. I know the engine is not over heating so why do i get this warning and squeal?

My F250 Will not start once the oil temp reaches about 117 degrees. Once oil temp drops it fires up. In the morning it only crranks for a couple of seconds. What could this be? I am getting over 1300 PSI HPOP while cranking. FICM Volts 48.5. Just no hot start. What do you think it is and how much at the repair shop. I have the Torque App, IPR values are good to I think.

Ever since having the EGR delete done, the oil temp has been LOWER than the coolant temp. I am assuming this is bad info from the sending unit? They are reading with in a degree of each other at start up, but when at operating temp the gauge will read lower. Before the EGR delete I had a delta of about 4-7* oil hotter than coolant.

Yesterday my truck started making a loud high pitch squeal at idle. Messing with it this morning I found when I turn the a/c on it quits. Then it will do it for a second at startup and quit. If the a/c system is turned off it comes back. I thought exhaust leak until I found the a/c link.

I've been searching for a while now but have not found an exact match to my problem.
So, Yesterday I was pulling a large load home (15K lbs) over flat land/small rolling hills and I experienced a coolant temp spike. And I am trying to figure out what caused it. I was traveling 65 mph about 2k rpm and 20lbs of boost, I was motioning the ECT, EOT, TFT, and Fan Speed via my scanguage and 99% of the time the ECT was in the 209-220 range, once it got up to 220 the fan would come on and the ECT would drop to 209 ish pretty quickly.
However, twice the ECT shot up from 215 ish to 240 within seconds then the dash indicator said check coolant temp then the fan came on and cooled it down to 200 within seconds, I did lose about 1/2 gal of coolant. So today I'm going to get a new degas cap (still OEM original) and continue to monitor the situation.
My EOT ECT delta has been a constant 10-13 degrees for the 3 years i've been monitoring it so i believe my oil cooler is still functions within spec and all my cold soak temps are within a degree or two for various ambient temps (20 -80) so all my sensors should be good.
Also, tonight I'm going to pull the EGR valve and check if there is any coolant in the intake, but if there is not, where should I start looking and what should I start worrying about e.g. head gaskets?

This is the only 6.0 I have owned. My tranny temp (with the Torque Pro) is pretty much always the same as my ECT. My ECT will move, and less than 2 seconds later, the tranny will move to the same temp. Is this normal? I was expecting lower tranny temps, but maybe it should be the same because of sharing the radiator.

I know they're supposed to be within 15 deg of each other. How bad is this? Pulling a small trailer with a polaris rzr on it. Running 75mph

For a month or two now my truck has been making a squeal and the turbo has been sticking after hard acceleration. The sticking was a woebegone unison ring and I was hoping the squeal would be resolved when I cleaned the turbo but it didn't, in fact, it got worse.
It used to be occasionally and go away after warming up, but now it's more constant than not. It goes away when the VGT does its idle cycle and once you get up to speed.
Here's the sound - YouTube.....

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.

My dad's 03 has had some work done after his oil cooler was clogging. New oil cooler, egr delete, head studs etc. The oil temp seemed to run some what high when he got it back. After a couple interstate runs on cold days 15-20 degrees, the water ran around 185 and oil as high as 218 but usually a bit lower. What's going on here? how could this thing be clogged again? It hasn't seem to gotten much worse since we got it back but not better either.

I recently noticed on my truck that my oil temp was running high, I would go down the interstate at 75 mph and the oil temp would get up to 215-218 while my coolant temp would sit around 192-196. So, I took it into the shop and was told it was most likely a bad oil cooler and had it replaced 2 years ago when I had my injectors and gaskets replaced along with my egr deleted. So, got the truck yesterday, going 60mph down the highway, truck ran an oil temp of 192 and the coolant at 188. Was great, but later on once I got to the interstate going my 75 mph, The oil temp jumped to 209 and my coolant sat at 192. Not sure what the deal is, was told the oil cooler was replaced and wanted some input on what else I could be looking at. I currently have 5w40 synthetic oil running in it. I have an EDGE CTS tuner on it and tuned it back to stock mode, but oil temp still jumps up to 209 and coolant remains around 190-192.

Bought this truck, and the engine coolant temp gauge does not work, so I replaced the sender, still don't work.

I have an 04 F350 and I was wondering if the fan is supposed to be locked up when the A/C is on. In max A/C with the fan on 3 it's barely keeping cool in the 95 degree heat we have been having. If I rev the engine I don't hear the fan noise like I do when the coolant temp hits 218 and the fan roars. Freon was replaced several months ago, along with receiver/dryer and orifice tube when I did the HG's. The A/C shop drew a vacume and did not find any leaks.

What the coolant temp should be around after plugging in the block heater overnight? Not looking for an exact measurement since this can be affected by OAT and the length of time it has been plugged in. But when it's -15 to -20F this weekend I was wondering what to expect.

Trans temp used to be about 185 max, now it's running side by side with coolant temps (200-203 with Mishy 200 thermostat) after I did the 08 pan and filter upgrades. I added 9.5qts after the change of Valv Max Life and checked and double checked the dip stick bout half way up hot. This is normal operating conditions, not towing anything. Checked with TorquePro App. Why it would run so high? Did I do something wrong?

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 code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

I'm excited to be a Powerstroke owner again! I had a 2000 with the 7.3L and since bought and now sold a Chevy 1500. Last week I bought a new 2015 6.7L. I am MORE than impressed and love the truck. Today I brought it to get the windows tinted. I have not had one issue with the truck since I have had it. When they finished with the windows, my check engine light was on. The shop I had it done it EXTREMELY reputable. They brought out their snap on scanner and pulled the code. p0073 for the ambient air temp sensor circuit high. Is this a coincidence that this came on after they got done, or could something they did while tinting the windows tripped this?
As I drove off down the road after determining I wasn't going to hurt the truck, the air temp sensor went from showing -40 to the actual temperature. What would cause this? I deleted the code when I got home with my actron, and the MIL has stayed off since, however, it shows P0073 Permanent ...

Coolant temps getting much higher than oil temps under load. Is there any problem that could cause this other than a bad temperature sensor? Reading temps with an Edge CTS 2 monitor. Think I'm going to hook up a mechanical gauge in the morning and see what it shows.

My 2002 PSD X with 258K miles has a high pitched squeal in the engine compartment. I only had a minute to look at it as my wife was leaving with it. But, I was able to stick my head under the hood and it seems like it is coming from the front of the engine. Trying to pinpoint where the squeal is coming from with all of the other engine noises is tough. I suspect one of the bearings up there like idler pulley, tensioner pulley, alternator, AC compressor, water pump. The alternator has about 70K miles. The other items I don't know.
