Ford 6.7L Power Stroke Diesel :: 2011 F350 Overheating When Engine RPMs Below 1300 Whether Truck Is Moving Or Not
Jul 28, 2015
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?

2011 Super Duty, SB, 6.7, Lariat, SuperCab, FX4 Undercover hard bed cover, Ford bed mat, and mud flaps.Traded a 2003 Expedition with 100k miles on it. It was time for a new tow vehicle, I tow a 30 foot travel trailer.(7000 to 8000lbs) The dealer offered me a deal at invoice plus all of Ford's incentives, so I couldn't refuse.
I have about 1300 miles on it and it runs fine. I have been noticing a wet spot under the right front of the truck, checking today it looks like anti freeze leaking from above the air condition pump. It makes about a 3 inch diameter wet spot, the fluid recovery bottles are still at the correct cold coolant level. I couldn't get my hand in that space to find where it is leaking from.

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??

I have a 2011 6.7 F-350 Diesel. I bought the truck new and I've never had any problems with it until now. I have a SCT Chip & Tuner. It needed an update so I returned the truck to stock and a code came up on my dashboard that said "reduced engine power" which obviously I thought was Normal because of the modifications done to my truck.
I updated my tuner and returned the truck to a performance tune but this dashboard code will not go away. My truck isn't reading any codes and there's no other indication lights on. The truck has Normal RPM readings but 0 throttle response. No power at all...

I am using my son's truck this week, 2012 F250, 120,000 miles or so. I left it running in the drive while I got something from inside the house. Guess it was idling approximately 10 minutes. When I put it in reverse the transmission would not shift and the truck didn't move. I killed it, re-cranked it and it went in reverse.
As I was driving down the road the transmission would change gears up and down for no reason. I stopped the truck, and put it in park. I would put it in drive and the transmission sounded like it wanted to slip. I put it back in park and the transmission would not engage. I then killed the truck, re-cranked it, and it drove fine for awhile and started doing it again,
I kill the truck, re-crank it, and we go down the road.

I just picked up a 2011 Ford F350 about 8 months ago. I have had troubles with the check engine light coming and going. Now it's been on for good with loss of power. I have had the codes read and they came up as the p0401 and a code about the def heater. I can not remember that code off the top of my head. After some searching I have found a video about the def heater but nothing about the Egr cooler/valve. Is there anything out there about how to clean and remove the the cooler as I will be needing to do repairs myself as the truck has no warranty.

Well it finally happened, a couple of weeks ago I was headed to an MX race and my check engine light came on and it started running rough. Long story short a piece of an exhaust valve broke off and went out through the head. Dealer has been great even though I was 300 miles from home and they did get me a rental(small POS SUV). Truck was supposed to be finished this week, but now they are saying the head gasket is on back order and they probably won't have one until the middle of April......... I can't be without my truck that long, but not much I can do. By the way truck is completely stock with just under 20K on it, and I have never had any issues with any of my Ford trucks or Ford diesels, even my old 6.0.

I just flushed my coolant system and installed a red ELC, Riffraff billet thermo housing, Ford thermostat, new hoses and Riffraff coolant filter. When I first started the truck and was waiting for the thermostat to open I notice at idle the flow from the coolant filter into the Degas bottle was a lot.
Fast forward a week and about 75 miles I have zero flow at idle and it will start to dribble at about 1300 RPM's and increase from there. It seems the flow would not be dependent of the thermostat being open since the connection is below it. I am wondering if my Donaldson filter is already full?
I used a flusher that uses air and water, after flushing I used air to blow to tap water out. How fast have you guys seen one fill up? I ordered 2 extra but just do not want to waste the first one

Just bought 2 new F-350 with 6.7s for a service truck and feed truck. I have a 2011 6.7 so pretty familiar with it. I noticed both these new trucks shift at a lot lower RPMs. At times if going from pasture to pasture I have noticed the tach at 900 rpm in 6th gear. My 2011 doesn't do that, it shifts at a higher rpm. Both of the trucks have been deleted, and I have a SCTx4 tuner in each truck and have both tuned to the lowest setting, Tow 40HP. Is this a fuel economy thing?

It's a 2004 6.0 excursion with about 190,000 miles. At 185,000 I pulled the motor and did new oem head gaskets, Arp head studs, bulletproof egr cooler and oil cooler system, bulletproof 48v ficm, strictly diesel regulated return, and I've been running gear heads srl tune before and after the truck was rebuilt.
Recently the truck has been acting up at random times. While running the gear head srl tune, the truck will lose power, the boost gauge on my edge insight will get stuck along with Icp psi, the water in fuel light and glow plug light will come on, and then after a few seconds it will clear itself and run fine. Last night I was on a two lane road and putting my foot into it and the truck did the same thing where it loses power, but this time the truck actually died on me while I was cruising at 60.
Same lights were on but this time the cruise control light fluttered while the truck was in the midst of dying. I tried restarting it and it took two sets of cranking before it fired and stayed running. On the way home I babied it and the truck lost power and the Rpms dropped and only the glow plug light came on. Got home and ran codes and I got camshaft and crankshaft position sensor codes and I tuned it back to stock, drove it around, and the truck ran fine, but while on a stock tune I am getting a egr valve code.

I am getting ready to go on vacation this weekend with my f350 and I was driving today when suddenly the truck shut down while going at about 25 mph. I tried to start it and it just kept cranking. I got it started 5 mins later and it threw a P0069 code. I drove for about 2 more miles and it shut down again, and started right back up. I'm guessing map sensor? This was the last thing I needed to happen!

A little background, this is an 04, f-350. It sis not start a week ago so I charged the batteries and it started, started fine this morning, (had not driven it for the week) Drove it to work, 35 miles, parked it, and it will not start.
I downloaded Torque and got a few numbers,
HPOP 1900 FMP 48V (repaired last summer) and FVP 11.5V.
Ran out of battery to surf more and look, so I am trying to figure out the app, and the issue with the truck. It seems to turn over good, until I ran the battery down, and the GP cycles normally, and the injector buzz seems good. Temp is in the 50's...

I've got a problem with an '05 f-350 with the 6.0. Initially I had a code for the #1 glow plug so I replaced the plug and the code was still there. Next I tested the harness and the rest of the plugs on the same harness and everything checked out fine. This lead me to the Gpcm which I then replaced. The first thing I noticed was when removing the old Gpcm I got a spark when removing the mounting nuts.
When I installed the new Gpcm the truck started fine and no codes came up so I thought all was good till I went to start the truck the next day and the batteries were dead. I thought I possibly left something on so i started charging the batteries but noticed they seemed to have a draw on them. I put my hand on the new Gpcm and it was very warm with the key off so I have the batteries disconnected till I can figure this out.

So I'm having a problem with my truck revving up out of no where. Happens more when I'm driving. It only shoots up a little bit but sometimes goes up 1000 more rmps. Happens for a quick second then stops and does it again. I've had the ckp replaced and it has an egr delete. Other than that it's stock. I got home and let it idle for a minute. The rpms fluttered up and down in small increments and almost stalled out. What is causing this?

I have a 2011 f350 that i bought with 30k miles on it and I now have 40 k miles. My truck will not go over 83mph it seems like its governed out there.. I have taken it to ford and they thought it was my key was set to max speed 80mph. but it was not and could not figure it out.. I have tried to disconnect the batteries to reset computer. I have not clue what is going on. I do have 35's (tires) on the truck with a leveling kit. But I have verified my speed only going 83 with ford and my own gps device..

New here but long time lurker. I have a 2006 e350 with 6.0, bought it from a friend not long ago. The work that has been done to it the last 50,000 miles is as follows.. New hpop, all new injectors, egr delete, sct tuner, stand pipes and dummy plugs. I had it for a week and would get a no start hot once in a while. This issue had become worse and the truck started to stall as the RPMs dropped. Reading here i replaced crank sensor and the stalling stopped but the no start hot continued. I took it to a local diesel repair shop and they did the following..
Use a test ipr (no change), replaced ipr pigtail (was cracked) air test (leak under pass valve cover) replaced stand pipes and dummy plugs on this side. They said no leaks and I was good. Truck worked as its supposed to for 1 day and the no start hot issue reared its head again. Took it back and now they say the hpop is bad. The pump that was put in about 50,000 miles ago was a bostech? do these go out? Sangauge reads good ficm, but seams ipr doesn't climb that quick.

I have a 2004 F350 with 6.0. My problem is the 4x4 will not engage from inside the truck. I have to get out and twist each hub to lock in the 4 wheel drive. If I rev the engine with high rpms the front will lock in with a big jerk. It use to lock in just by turning switch. What is the best way to fix it?
