Ford 6.0L Power Stroke Diesel :: 2006 - White Stuff Around Coolant Cap - Leaking?
Jul 26, 2016
2006 6.0l
Just noticed yesterday during an oil change that I had white stuff around the coolant cap on the overflow bottle and that no coolant was visible. I went and got some antifreeze premix to top it off and it only took around 1 quart. Today after driving it approx 30 miles, the coolant was again missing.
When I changed the oil the other that same day there was no coolant in it, and I don't have any puddles on the ground. Whats going on?
EGR is deleted with a sinister kit, temps are fine, today it was 94 degrees and the truck was running at 194 oil 192 Coolant when getting off the highway after 15 minutes doing ~75. I've got a little bit of stiction going on but besides that nothing seems wrong.

Last week I noticed I was having to refill coolant in my excursion more than I should. I hae a mechanic friend now trying to diagnose the problem. he said he doesnt think its the water pump and there's no white smoke. Are there common leaking places for the coolant on 6.0s he should be looking for?

Ok I bought a 2006 Ford F350 with 6.0 after driving for about 3 weeks I noticed a little bit of coolant was disappearing out of reservoir. So yesterday I was driving with a load Reservoir overflows replace coolant with one gallon of coolant and finish trip with no issues. I started truck today and it will not stop smoking it is also not overheating after hearing about head gaskets. I'm hoping it might be EGR cooler white smoke smells like raw diesel fuel. What to do?

I noticed about 1 year ago I had diesel in my coolant but wasn't sure.. took it to a Ford Guy about 45 minute's away.. He seems to know his stuff but when he tested the coolant the results said less than 2% diesel.. But he did find an injector issue and swapped it out..
Forward to present.. there is diesel in my coolant now , since the level is rising to almost overflow and I believe this has been doing on for quite some time as I have that smell you get in the cab..
BTW - All injector cups have been done about 3 Years ago.. On another note , I get white smoke on start up especially if the truck has sat for a day or 2.. What can cause diesel in the coolant.. I did a complete coolant flush this summer and was super **** about getting all the old coolant and gunk out.. Ended up with only clear water coming out the degas

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 would like the hear what others have to say about the problems I'm having with my 2006 F-350 sd xlt 6.0 with 113,000 miles on it. It's being used as a tool truck mostly going from a shop on the property to close by buildings on the same property. In other words very short distances. Used occasionally to take a dump trailer to a close by dumping ground.
1. White smoke from exhaust. I've read this is most likely an ERG cooler that needs replacing. Any other possible causes? If I end up having to replace the cooler is there a stock cooler that is reliable or should I get the one by bullet proof?
2. Diesel is dripping from the muffler weep hole. Last full tank lasted only 60 miles. Could this be the oil cooler? Anything else? If so is the Ford replacement cooler OK or should I go with an upgraded cooler?

I recently was informed by my local mechanic that fuel was leaking into my coolant. He said I had a cracked head based on this and it would give soon. Well, he was right, and now I need to do a head job. I found new heads, but would like to know how many book hours this should take before I proceed. He gives me a wide range of time, and don't want to get taken advantage of.

I have a 2006 v6 ford mustang and just developed this problem yesterday.
When I drive the car, the temp guage stay right in the middle, but when I park I get white smoke come from under the hood. I popped the hood and saw coolant leaking from where the top radiator hose meets the engine block. This was producing the smoke. When I checked the hoses, the top hose was hot and hard, the bottom hose was cool and soft.
Extra info:1. I did not touch the radiator to see if there were cool or warm spots2. The overflow bottle looked empty or close to it, but the engine was still hot from driving to work
Thinking this could be one of the following:
1. bad thermostat
2. clogged radiator
3. Air bubble somewhere blocking the coolant flow

Newbie hear to the 6.0L's. But I'm learning an awful lot really quick from all of you here. I've read lots of tech stuff on these EGR Coolers, oil coolers, FICM tests. This is what I got happening right now.
2004 F-250 6.0L. Today was 45 degrees in Reno. 5400 ft elevation. Tried to start it without block heater. Would not even crank. It tried to crank but sounded like it locked up on first crank. Tried again, nothing. Same. Tried yet again and finally got to getting the engine to crank, but wouldn't start after about 5 seconds of cranking. Waited a little while not wanting to burn out my FICM, then tried again. Same as previous, would crank but not turnover. Checked batteries. Both were over 12.3 V cold, motor not running. This next time, turned key on and let it sit in ON position for about a minute. Then cranked and it took about 5 seconds and then the motor finally cranked over. Lots of black smoke as usual for a cold start like this. Battery volts after cranking over and running were now both over 13.6 V.
Keep in mind the truck has started better than this before in 15 degree weather just about a month ago.
After it started I noticed what appeared to be oil/coolant residue directly underneath trucks transmission area. It was not tranny, but in that area. I got under the truck and can see this fluid coming from EGR Cooler area.
Now for the smoke. Just stared smoking on start up. White smoke. Then it would disappear as engine warmed up. Now its constant white smoke when warmed up and applying the throttle. Smells like coolant coming out of exhaust. Not diesel.
I parked truck facing downwards on my driveway. Then I checked EGR Valve. When I pulled it it was WET. Not dry. Peeked in EGR Valve hole, didn't see coolant. Just wetness. I did change gasket and rings on it the day before as well.
As for FICM, it reads 47.9 Volts on key turn, 48.1 on cranking and 47.8 running. FICM good by all standard 6.0L literature. Degas bottle passed pressure test holding near 15 PSI for 20 minutes! No oil in degas bottle that I can see.
Truck is stock. Is my egr cooler and oil cooler shot? Would a bad egr cooler or oil cooler cause this awful cold start? When I plug in the block heater, it starts NO PROBLEM, but still white smoke. Also, NO loss of power at any time.

On our '04 Ex with 195 on the clock I've discovered a pretty good leak dripping. I crawled under it an coolant appears to be dripping off the back of both exhaust manifolds.
Less than 1000 miles ago we had an oil cooler and egr was pulled and freeze plugs installed by an excellent well respected 6.0 diesel shop. I don't think both gaskets could have blown at the same time creating two leaks. It runs fine, degas bottle still has coolant in it.
I've seen other threads that point to the heater core hose and more commonly the "orange" egr hose. It appears that an egr delete removes the hose - I think... but would that Blue / orange hose be there if the cooler was just capped and electrical unplugged?
The shop is going to look at it Monday but I'm trying to understand it better ahead of time.

I LOVE my Super Duty and with only 15k on it (have a company truck) plan on keeping it for a long time. I've had an EGR Delete and new Oil Cooler along with some misc things done to the engine and turbo, about 6g's worth. Now my mechanic at NCB is telling me that the reason I'm loosing coolant is that my head gaskets are leaking. I'm looking at another 5-7 grand which is a no go for me. I'm thinking of doing the work myself, especially since I've seen where i don't have to remove the body to do it.
Okay, here is the question, I've been having a hard time finding a comprehensive list of the parts I should be getting to do the job. Looking for a list or link on what I need to do it correctly and anything I might want to do while my engine is apart so I don't have to do this again?

I have a 2012 with 41k miles on it. I noticed it was leaking oil from the front of the motor. So...I checked the oil and found it to be over full. Assuming I overfilled when I changed the oil (2000 miles ago) I changed the oil again and made certain it was filled properly, 13 qts right in the middle of the dip stick. The oil leak stops. 1000 miles later the oil leak starts again. Too much oil again and the coolant is mysteriously low!!! The dealer can get me in two weeks from now.
Time to get the 7.3 back on the road, I knew I kept the old girl for a reason. 262k of miles no truck should endure and still going strong. I was 21 when I bought the 7.3 (16 years ago) and beat the crap out of it. This truck has been pampered compared to my past trucks. I was hoping to get 14 years out of this truck too.
Is the motor OK after having coolant sloshing around in there? I just hope ford stands behind this one. I have a feeling it's not an easy fix. I am sure glad I left everything stock.

I've just finished a marathon replacing the y-pipe, and doing the IPR screen. I had many seized/stripped bolts to contend with. 2 I had to cut off in the most awkward places.. Anyways, it all came together and completed the project late tonight...
Befoer even starting the truck I noticed coolant dripping from passenger side manifold/block heater area.. I obviously must have damaged something in my reefing on turbo to get it lined up with exhaust pipes, etc...
I cannot see the source of the leak, but it seems wet above the block heater, but pools there then drips.. I'm curious where to look. Could I have damaged the EGR cooler and its coming from there? At the manifold joint closest to the back, is there coolant flowing there? I am pretty frustrated, because after going through a day like to day, ripping my arms to shreds, straining for 12 hours straight, then having yet another issue to figure out...
Also this is as best as I could get the y-pipe to meet the turbo... slight gap at bottom.

On Friday am I noticed a 6" sized puddle on the garage floor. Coolant leak on the drivers side coming off the frame. Dropped it off at the dealer on Sunday and today the tech tells me it was in fact a radiator leak and the new one will be here wed. They hope to have it buttoned late Wednesday. I am assuming all will be covered under warranty.
I have 23k miles logged and had just got home from a 1300 mile run pulling about 18k worth of hay and trailer. Truck performed flawlessly. Averaged 11mpg for the trip. I am hoping this is the first and last radiator replacement I have to go thru.

I recently had my injectors changed at Ford and while I was driving it started dumping coolant. If the leak can be cause from the injector replacement or if they didn't put something back together right... 2005 f 350 6.0...

I spotted a leak last nite on my 6.0. It is coolant, running down the right rear on 2 metal lines that go to the trans I think. It was dark and 24 degrees so I did not spend too much time looking. Shut the mother down til I could research. 2004 250, 6.0 FX4x4, stock. Coolant was changed to green by previous owner. Bought it 4 months ago. 187,000 miles.....

06' with 85,000 on it started smoking yesterday. When idling , and stopping at red light, and then sometimes it doesn't. Run it this afternoon for about 10 miles, let it warm up. Ran good and smooth didn't smoke when cranked then at the red light it started to put out a little white smoke. Drove back home, pulled egr valve and it did have a little wet on it, the coolant level has dropped some to. I scanned it and it didn't have any codes, no misfires or anything! Is it safe to say that the egr cooler has a small crack in it and its just starting to leak?

We have two 6.0 trucks and one is having issues. A couple days ago it started to have white smoke like crazy upon startup, and when you slowed down you could see smoke, any speed and it dispersed so it was not noticeable. It got worse very rapidly and I haven't ha. A chance to work on it, it's also burning antifreeze, that's what the smoke is. Recently the egr started to act up so I cleaned it and the code for a sticky egr went away. It came back after a few months so I cleaned it, it went away for a few days then came on with the symptoms I just described. It has been moved at work a couple times the last few days, but not driven. Today I had to move it and it would not start, no white smoke either while cranking. I read the codes and this is what it has:
P0674- cylinder 4 glow plug control
P0404- EGR control circuit range/performance
P0299- turbo underboost
P0403- EGR control circuit
P0405 EGR sensor A circuit low
I would say it's a head gasket or EGR cooler, no? What course would I take to find out what's wrong? The truck in question is a 2006 F350 SRW King ranch. It has 115k on it, and the majority are work miles pulling trailers.

My 06 6.0 is blowing a fair amount of blueish, whitish smoke only on initial startup, then continues to blow smoke slightly for around 10 min until it's warmed up. It seems to be getting a little worse as time goes on, only on startup though. truck has no other issues otherwise, has an egr delete, and some old edge tuner. I don't think it's head gaskets, no other symptoms.

I have a 2006 f350 with 75k on it, has a mild sct towing tune, and 4' turbo abck dual exhaust. It recently started blowing whiteish smoke, so i did an EGR cooler and valve delete kit, and it stoppe dsmoking for a while.. coinsidence?
It has recently started again, at idle there is no smoke, and taking off slow from a stop, it doesnt ALWAYS smoke. but leaving a dead stop, if i get right into it, it billows whiteish smoke, and if im cruising, romp on it, let off it, then get on it again it will smoke.
Ive been told fuel pressure, injectors, turbo seal etc. when i had the down pipe off, no sticky black residue was present, so im counting out turbo seal (for now). I purchased the blue spring upgrade for fuel pressure, because i was told its not getting the right amount of fuel, once i get that ill throw it in and see if it fixes it.
whats yall's opinion? is it worth have it checked for a failed injector? as i said, no EGR in the truck, no loss of coolant either, oil is clean. It does seem a little sluggish at times off the line now as well.
