Ford 6.0L Power Stroke Diesel :: Coolant Leak And Pressure Loss
Feb 21, 2017
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.

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.

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.

So I have a 2003 6.0 king ranch w/ 164k on it.. EGR delete, high pressure oil pump, coolant filter and SCT tuning. A couple months back I had a coolant flush done. After about a week the coolant tank was empty.. Engine heated up due to loss of coolant.. I flushed system again and put ford gold coolant back into the tank. (5 gallons). A couple days later and coolant was very low and engine heated up?? There are no signs of leaks anywhere...Added water and it cooled back down. I'm lost. EGR is deleted but no studs done.....

Loss of coolant! I have a 2003 6.0 diesel with 200,000 miles. I put in a new oil cooler and ipr egr delete two years ago also flush the system and added a coolant filter. I filed it back up with the red antifreeze. Now the problem I have never lost any coolant since then and my deltas are about 5 degrees. But the other day I pulled a heavy load the first one since I did the repairs (coolant got up to 220 degrees and would drop back down) when I got home the coolant tank was about a inch low. I let the truck sit about 3 hours and checked it again and it was back at the full mark. Drove it the next day and it's back low about a inch, Any clue what's going on.

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.

Recently I had a radiator hose split while traveling. The EOT got up to 250 degrees before I could pull over and stop the truck. I flushed the cooling system with water, replaced the thermostat, and added Ford Gold coolant as per the recommendations in the Tech folder. My oil temps are higher now than prior to this incident. Unloaded on a flat road my deltas are about 10 to 12 degrees @ 60 mph.
My water temp will stay around 190 to 195 degrees while my EOT have reached 212-215. I pulled a small utility trailer and saw a delta of 17 degrees this was at about 75 mph. Typically unloaded I would only see a delta of about 8 degrees and this was at 80mph. My question is do you think a EOT of 250 would burn the oil, I had Shell Rotella T5 5W40 in the engine. Would it be possible that the oil cooler is partially plugged from this temp?

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.

I am having a heck of a time finding this coolant leak. It drips off the power steering pump. I replaced the upper radiator hose and the heater "y" hose that goes to the bottom of the Degas bottle. I recently replaced the lower radiator hose as well. So the truck runs normal. When the system is under pressure I do not see any leaks. But after the engine is completely cold it starts leaking a small puddle of coolant. Its appears to be coming from the power steering pump. But I am sure its something above or near it. This is on my 2005 Excursion with a 6.0. Can the water pump be going bad and leaking this direction. I would expect a water pump to leak straight down the middle of the engine. What to look for? The thermostat seal stays dry. but it has to be in that area. What is really messing with me is. When it is hot and pressured up It does not seem to leak. Only after it has been sitting for hours and cools off..........What the heck!

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.

Nothing to be alarmed about, I'm just letting y'all know I have a coolant leak on the front of the motor. It leaks about 8oz. Of fluid/week.
I have been through the radiator issues, 5 in all on my '08 and 1 on my '11 at 52,000 miles. This one is different, I'm pretty sure it's the water pump.
I'll give the official word as soon as I can get it diagnosed. I guess it's because I tow all the time, nothing real heavy, just everyday use. Truck is hardly ever on its own.

Seen a coolant leak near the back of the block? I did an oil change and noticed coolant on the bell housing.

I installed a BPD EGR cooler about 4 years ago just as a preventative measure (along with an oil cooler) in my '06 F-250 6.0. About 6 months ago some coolant was found to be coming down the rear of the engine and onto the garage floor but only in the mornings after cooling down and even then not every morning.
A couple weeks ago I did a coolant flush and put the red ELC coolant in and now I can see better where the coolant is coming from. It appears to be coming out from the O-ring between the cooler and the intake manifold. I did check the torque on the stud and bolt and they are tight.
Is there a way the drop the cooler enough to install a new O-ring with out going through the whole process of removing the intake manifold and everything that is associated with that? The thought is daunting...

I just replaced the oil/egr cooler, stand pipes and dummy plugs along with all suggested upgrades, just filled with oil hooked up batteries and while filing with coolant it started gushing out from under the intake in front. I think I see an o-ring pushed out.. I hope I can lift the intake without removing the turbo!!!

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.

Just finished doing my own heads on my 2005 Excursion 6.0L. Turned it on with really no problems. After running for about 5 min. it started smoking. I also noticed that I had some pressure in the coolant reservoir. I toke off the cap and it stopped smoking. I placed it back one and it started to smoke again. Oil has water now. I used ford head gaskets and ARP bolts. I torqued the bolts down to ARP's specs and torque pater, 210 lbs/ft. I also replaced the oil cooler, stand pipes, stc and the dummy plugs. Also from Ford. I don't know where I went wrong.

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.
