I have been hearing that also, but hear is something I have not read or heard of yet and I got thinking about it.

Any other engine you look at has a place for the coolant to go when it expands to much for the radiator either out a vented cap where it is spewed every where or through a hose to a catch can, where when the engine cools the coolant is pulled back into the cooling system due to the vacuum that develops.

What is everybodys thoughts on this?

 

NUMMIT,

if that was the case there would BE ALOT OF 6.0'S LAYING ON THE SIDE OF THE ROAD. There are alot of people that drive these things and have no idea that they are doing it.

I just got a heads up from a ford master tech. Corporate ford has leaned on him for some fixes in the past on certain things, and they are coming to him and a few other techs around the country. He said he was going to bypass the EGR cooler and see if that stopped the puking on a few of the harder pulling trucks, IE the truck that runs a big trailer for the dealership picking up cars all around the country. I haven't checked back, but it looks like its working. Not sure how the EPA is liking this fix, but hey, I think it would be worth a try.

 

That is the most probable reason on truck that are really crank the power, but on stock and near stock other reasons are suspected.

Mine (like others) only does it when pulling a heavy load.

 

The dealer replaced the heads on my truck at 14000 miles. I've got 17000 miles on it now and no puking so far.
Only puked coolant while towing at first, but at around 12000 miles it would puke with out the trailer. The truck is stock, no mods.
When I got the truck back the coolant bottle was filled past the top line. I've got 3000 miles on it with some heavy towing in hot tempatures and the coolant level has not moved.

 

Great info. My '03 6.0 PSD started puking coolant when I loaded it with a popular tuner that I felt was the best tuner for my truck. The mileage on the truck at the time was around 34,000 miles, bone stock, prior to starting a long trip to Alaska. The engine had never overheated while pulling the same trailer to Northern CA, Oregon, Washington, Canada and beyond before returning to SO Cal. prior to installing the tuner. With the 2nd tow tune selected, I started the trip to AK, it overheated right off the bat going up the Cajon Pass, and I heard a strange new high pitched squeal coming from the engine going up the hill. The temperature climbed very fast scaring the hell out of me, but cooled very fast at the summit. All was well until I was in Montana climbing a particularly steep grade when the temperature climbed so fast that even coming to a very slow speed the temperature gauge continued to indicate max temp. I was sure the engine was history, but the temp finally started to return to normal. At the first stop, I reprogrammed to the stock program, and noticed that the water bottle had puked all the coolant in the bottle, it took a full gallon to bring it back to normal level. With the stock program the overheating problem is gone, the truck has peformed great, and the puking problem is gone, and the truck has not overheated once.
I have to say that in my case, the tuner was a bad idea for towing. It performed better when not towing, but does better towing with the stock program, and it does not puke coolant.

 

There are many trucks that puke coolant stock, and there are many trucks that do not puke coolant when programmed.

Ford has acknowledged there is a problem with coolant expansion, head gaskets, head bolts.

Trucks that puke coolant programmed are accentuating a factory problem that in some cases isn't quite extreme enough to show up stock.

There are far more trucks that don't puke coolant when programmed than there are trucks that do.

 

I can't believe Ford would acknowledge that they have this problem.The only thing is if a programmer brings this out why anyone would put one on their truck. As stated by 6.0Rules his did this with the programmer only. I believe its the other way that most of the trucks that have this problem are from programmed trucks. . It would be an interesting poll if guys were honest and would say if they have a programmer or not.Most say no because they know thats why its puking coolant. Maybe the 03 and 04's had a problem stock but I've havn't seen a problem with an 05 that wasn't programmer related.

 

Keep in mind, this happens on a limited number of trucks.
It is a Ford problem and believe it, Ford has acknowledged a problem...wouldn't be the first time.

I have dyno and load tested well over 100 stock and modifed 6.0L diesels.
At least 11 trucks puked coolant BONE STOCK.

 

I've got an '05 that is stock and it started puking coolant while towing at 5000 miles. Nothing that the dealer tried corrected the problem, until ford stepped in and replaced the heads. So far i've got about 3000 miles on it and no puking.

 

Try changing the thermostat to a 185 degree. My friend says when he installs programmers, that he does not have an issue. I would try it, but do not have a programmer yet. Changing out the thermostat should be a piece of cake.

 

My '05 King Ranch 350 has less than 5k miles, bone stock and has coolant sprayed all over the engine and hood. I noticed it a couple of months ago, prob around 3k miles. Most of my driving is back and forth to work, 5 miles away. I am in Northern CA and it has not been Hot here yet. The heaviest thing I have towed was a motorcycle trailer, at very most 1000 lbs.

Am I destined to have problems if I put a chip in? Should I have the thing into the dealer to fix it? Will I be told this is normal??

 

Trauma I would take it back to the dealer asap. That way you have a paper trail should something go wrong. They should be able to fix it. I would NOT put a chip or programmer on it untill its fixed . Thats the first thing they will void the warranty for. Some have said the heads were replaced and fixed the problem others still have it.

 

Hey People....
If this is one of the problems that causes the puking, would we not see some type of increase, or spike, in the temp. guage, or is it not that accurate? My truck never had a perceptible change in temp. when I was having puking issues. BTW, the last time I had puking, I had the Edge on level 4, ambient temp. 90 degrees, ran hard WOT, then part throttle on a very deserted road, in the 95-105 MPH range for about six miles....puked just a few ounces. Towed 9900 lbs. about the same time with the Edge on level 1, no puking.

You are correct...and your description above is consistent with lifting heads.

 

I do not believe that there are more trucks puking when tuned than not tuned. My 03 has had a residue of coolant under the hood ever since I purchased it. Every time that I wash it clean then after a trip or towing it is back. I have never seen any fluid just the residue. I have also added a programmer and I believe it pukes less when programmed (edge level 3) than when it is stock. The local tech has told me he has seen lots of stock trucks that have bad coolant caps and replacing them usualy helps. But the others they can't find a fix. If FORD would spend more time trying to fix these problems than trying to deny claims then they might once again be the Truck of all Trucks. And dont get me wrong thay shouldn't have to warrant anything that they are not responsible for, I just would like my truck back the way it was when I purchased it in dec 2002 and that included the quiet engine, engine braking over 50 and down to 0, Fuel economy. Then they need to find a fix for these mistery things that I have had to live with for the last 2-1/2 years like "engine Flutter" and this puking problem. There is nothing seriously wrong with my truck unless you believe these guys that say the heads are lifting of the block and streaching bolts, there has to be an engineer here that figure out what kind of psi it would require to stretch head bolts. But I may be wrong just my opinion.
