Ford 6.0L Power Stroke Diesel :: Losing Coolant Pressure - Pin Hole Leak Somewhere Once Shut The Truck Off
Apr 11, 2017
I noticed when I shut off the truck about 30-40 minutes later I'll open the degas bottle cap and notice there is no pressure.
I used a coolant pressure tester kit and pumped in 16PSI but couldn't hear or find the leak.
I'm going to buy a smoke machine in a month or two but until then, can I still drive the truck ?
I'm guessing it is a pin hole leak somewhere as once I shut the truck off... there is a lot of coolant pressure.

I am in the middle of a several thousand mile road trip, and I am with family in Utah when this evening I noticed a puddle under my 6.0 Excursion.
Coolant leak? - YouTube
The fluid does not smell like typical coolant, but from the location of the drip, I cant think of it being anything else.

Well got home and the front of the truck was covered in coolant. I must have driven 2 hrs after I noticed no coolant pressure, but temperature was great so figured it was another crappy cap. Looking to get a quick turnaround. Need to go out of town for work Saturday so I have this week to get it done.
Just put a stock unit back in? I don't think I need to do anything else in that area. Belt/pulleys/radiator all done last spring.

I recently had an upper radiator hose bust and ever since I have been having a slight water leak. It appeared to be coming from between the layers of rubber on the new hose which I replaced twice since the incident. Both hoses had water seeping from the same location. This afternoon I plan on doing a pressure test on the cooling system to diagnose where the water may be coming from.
My question is could a loss of pressure cause larger than normal Oil and Water deltas? If I have to replace the radiator is there a particular manufacturer or type I should avoid? Should I try to get a factory replacement from Ford or would an Autoparts unit be sufficient? The original is still in the truck now with 286,000 miles on it.

My good friend has a 2011 6.7 and has been dealing with a coolant leak for a few months. Dealership has had the rig a few times and said it passed " a pressure" test etc. and they see no issue, yet he finds a puddle under the truck when after it has been parked. How best to check it out? I'm not familiar with some of the common trouble spots on the 6.7 like I am with the 7.3.

2003 crank no start, 196k bone stock truck egr still in truck and stock head bolts. Replaced the icp sensor and ipr sensor, both from ford. What happened is I got fuel then about 15 minutes afterwards my truck acted like it was going up a hill and was just losing power and shut itself off. ficm tested 48.5 volts all 8 injectors tested good and there is oil pressure. Had an egr fault code but I'm at a loss.....

2011 6.7 with 3.55 gearing. Just got the truck. And it seems when its cold the truck will rev high in 3rd gear and then sort of fall into 4th gear sort of losing power for a split second. If I gas it hard, its not as bad. Usually only happens like I said when its cold. Check the trans fluid its full and looks clean. My guess is some sort of sensor or the computer???

My 2006 6.0 is blowing white smoke/steam and Im losing coolant (not out the top). Pulled the EGR valve and its wet down there. All signs lead to EGR cooler? I've been reading a lot on this forum and Ill do the oil cooler at the same time. I seems VERY important to flush the coolant system before I tear into this. I am afraid of hydro locking the motor or ruining the head gasket or stretching the head studs if I run the truck. How can I do this without further damaging the engine? I am doing this myself. I'll have 3 solid days to finish this job because I have to tow my trailer in 5 days.

I have a 2003 6.0l... When I first bought truck, seemed to run fine. Since then truck has broke down on me once. I took it on a six hour drive, and couldn't turn vehicle off, because if so, truck wouldn't start back up until cool. After getting to my destination, fans seemed very loud every time I pressed pedal, and seemed very sluggish. Drove it a couple days and boost was low and fans continued to sound like they werre engaging even when I first started truck for the day. Had truck towed to shop, because it cut off on me when driving.
At shop : Truck had air filter, water in fuel sensor, o-ring for draining plug, new ICP sensor and harness, and HFCM cleaned up as it was filled with gunk.
After shop : Fans quit being so loud, but have not had near the boost I had before issues started. Truck struggles to go from stop, and around 15 psi boost gauge starts shaking erratically. Also, I have been losing coolant in a short period of time, and can't see any leak coming from anywhere, and also my radiator has been making a sloshing/gurgling noise and it will stop, then come back all within bout ten seconds. And I guess while I'm writing, I should mention the bucking after it downshifts in about third or fourth gear giving it gas makes the truck buck until the RPMs are above 2000 or it upshifts or downshifts, and at an idle seems to miss until warm.

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!

So I am out of town about 120 miles from home on a job. I was driving down the mountain road to the store and my tuck just shut down. Lucky for me I was able to get into a turn out. So I try to start the truck and it will not fire. I check for codes I am getting p2614, p2617 so I was able to clear the codes and get back to the house I am staying in. What is going on with my tuck. Oh ya the code did not come back on in the 15 min drive to the house. Also just finished up doing a y pipe and my egr o ring so I and the intake and all that off.

Just got this injectors done. Filled the tank up. Drove for 1/4 of a tank. Went to leave out yesterday. Made it out of my subdivision and down the road 3 miles or so. I was going 55 when the truck stalled. I tried to start the ignition it would turn over, but wouldn't catch to stay running. I did this at least 8 times. Friend came with Ether. Tried 3 separate times, truck started going dead. So i was about to give up... Tried it 1 last time, it fired up like a champ!

So a few day ago my truck shut down while driving. I posted up and checked the ficm harness as suggested. Things were a bit lose so I zip tied my harness around the ficm. Thought it was all fixed and test drove it and it shut down again. I tried to start it a few times and my ICP was a tad low about 450 ,I have a brand new ICP and harness. Checked my scan gauge and I have code p2614. I cleared the codes and the truck started right up. I need to get this sorted out I was supposed bro go home tomorrow from working out of town all week about 100 miles from home...

Truck has a high oil pressure leak, only leak i have found is in the high pressure rail, I cannot get to it till sat, or sunday. So I have to let the oil cool before I can start. Any way testing to find the right temp for Oil to thicken enough to Build? I've been here for hours and its went from 180's to about 100 now...

I have a High pressure oil leak somewhere, and where it can be. I tore the oil rails out and replaced the nipple cup seals last night. I got it all back together and air tested it and sure enough a leak is present. I have no problem paying for your time (I always provide good beer). I can rebuild gas motors all day long, but these diesels has me thrown for a loop. The frustration I am experiencing is crazy at this point. All the injectors are new, and the dummy plugs and standpipes were replaced as well.

Adding a coolant pressure gauge to truck? There are some expensive kits but considering I already have a gauge that would work, could I just buy a 5v sending unit for fuel pressure or oil pressure and have it work?

I just did a pressure check on the cooling system on my 04 6 liter. It reached 16lbs towing an enclosed trailer and into a strong head wind. I was just wondering what's the Normal pressure suppose to be, or is there a Normal pressure. I'm using the new style cap with the larger spring in it and it didn't kick any coolant out.

Im lost here, my 6.0 is building coolant pressure on start up, and the temperature is not overheating. I cant tell if the pressure is staying high while driving, but its blowing coolant passed the cap. Thermostat? The truck was on a coolant pressure tester for 24 hours and never lost a pound of pressure.

I was driving to a job this morning with my truck loaded with tile for a job and it just died.
It has power to the lights, radio, etc. But when I try to start it it does not even crank and it has no fuel pressure on the gauge and the pump is no running.
It is as if the truck has no power. When it died is was like I turned the key off and it just stopped.

I have a leak in the fuel pressure regulator housing. Seems like a common problem. I ordered the new kit from FICMrepair.
While I wait for the new kit to arrive, is there any risk other than loosing a few mm of diesel fuel driving the van? Will the leak damage injectors?
It's not gushing out. I have smelled diesel fuel for the past 3 months and could not locate it until last weekend.
The kit is coming next week and I like driving the diesel van over my under powered 6 cylinder E150.
I want to clean out the EGR while I have everything apart. I have heard that some people just disconnect it. There is a write up about in the tech folder and it went way over my head.

What could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.
