Loosing Coolant At The Reservoir
 

I have a 2005 6 litre and it blows hot coolant out at the resivoir. Just wondering what my problem is?

How hard does it blow out? If it's ginning, cracked/warped head or leaking head gasket.

only blows out when under load. like towing a trailer or with the programmer turned up and with my foot in it. not alot and only if it is hot outside.

AC turned on? Partially blocked radiator, sticky thermostat, programmer may have something to do with it. DB has a few Ford gurus, and they can go a little more into the programmer end of things.

By the way, welcome to DB!:U:

Could be a couple things.

What progammer?

I'm gonna say it's time for studs most likely though by your statement of it does it under load.

did it with both Banks 6 gun and Predator downloader

does it with both Banks 6 gun and Predator sport downloader

Might be too late to try w/ out either hooked up. Worth a shot!

Predator has been know to blow head gaskets on the 6.0's. How long has it been doing this?

My money is squarely on headgasgets. The other option would be a cracked EGR Cooler, but that USUALLY will leave a small puddle of coolant behind the passenger side front wheel.

My 04 F-250 would blow some coolant when I first got it because it was overfilled with cooltant from the factory.

it's been like this for almost a year. It did it for the first time on the way to work when a V6 mustang tried to pass me and i put her to the floor, when i got to work i noticed the coolant in the wheelwell i opened the hood and found that it was coming out of the resivoir. I had my Banks plugged in then so much for safe i guess.

thanks everyone

also -- I've read a LOT of people just have faulty coolant caps and when the system gets pressured up (like under load) it starts spewing thru the cap...

try the simplest first -- replace the cap... if it fixes it - GREAT! if not.. then you start moving on to the more serious things...

Usually they are faulty because of excessive pressure.

I replaced my cap and the tea kettle sound went away for a little bit, but it showed back up. Combustion gasses were making it into the cooling system.

Since the OP stated he has used a Predator, I would venture to say that he has stretched headbolts. Predator programmers have too much timing on the top end and have been the leader in headbolt stretching. If there is no coolant on the ground where I described earlier, that would pretty much rule out a cracked EGR cooler.

i have replaced the cap. Didn't help. Started to loose the coolant with the Banks 6 gun in. Oh well i guess she's very sick then, thanks everyone for your help.

should still be under warranty...

take all the stuff off of it and run it as long as you can..

then take it in for studs and make sure they put in some ARP or other aftermarket set!

I know you said it started with the banks in, but the damage may have started earlier than that.

To be perfectly honest, the 6.0's have been known to stretch head bolts in stock form. So with ANY tuner it is a matter of WHEN, not IF you will need head studs.

my milage is over for my warranty. and that was when i threw all the stock stuff out anyhow.

You have more than 100,000 miles on your truck?

I think this common with the six leaker cousin said his did it and his has under 20k. If it leaking out of the reservoir then it is probably not you head gaskets or stretched head bolts.

Ummm that's where mine was blowing out when I needed head studs.

Some of them were over filled from the dealer and would do it once or twice, but if it is recurring then usually the culprit is the headbolts/gaskets.

But what do i know? I mean I've only been there, done that and have the ARP atuds to prove it.

egr will show all the same signs as a blown HG.

That is true the egr will show similiar signs to a blown head gasket. I would pull the cab put headstuds in and while your at it put an egr delete kit in it and run it. Just my opinion we have 4 f 550's at work. if you can swing it i would upgrade the turbo while the cabs off just easier to do. as our bone stock trucks blow headgaskets and seem to go through egr's.

Blowing Coolant
 

Well I am sorry to here that you are having a problem with your coolant and overflow. I had t same problem since day one I bought my truck back in 04. I had my truck in the shop 4 different time. I took it to the Ford dealership in Carthage, Ny; Watertown, Ny; Munce, Ind; and then finally to Moser Ford in Portland Indiana. The mechanic there has 18yrs experience with stock and high performance diesels. I had left my truck with him for a few days and to come find out, it had a head problem. Listen, this is a factory problem. On the 6.0, the head bolts come loose after a few thousand miles. Under normal driving you wouldnt notice any blowout of collant. Never once did I see any coolant in my oil. Only under boost would I notice coolant blowing out of the coolant box. Ford will swear up and down to you that you have no head problem. However, if the would tear your heads off, you would see the blow-by (something similar to blow head gaskets). It isnt a EGR problem. I wouldnt take "NO" for an answer. I can give you the contact info for the mechanic if needed. Also if you call EDGE and BANKS, they will tell you the same thing about the head bolts. If you have notice, your truck doesnt get as good of fuel mileage as it did once you first bought it. During on of your recalls or oil changes, Ford burns a new factory tune into your computers rom. The did this to back off the horse power and eliminate the pressure on the heads to keep the bolts from coming lose.

Ford has never done an oil change on my truck or been able to flash my computer. I have contacted Banks about it they didn't care to hear about my problem (must depend on who you talk to). Anyhow my waranty is over, so i got them changed at NADP in edmonton alberta, they also did an EGR delete and the truck seems to run alot smoother now( might just be me). thanks anyways.:c:

I have the same problem. I am loosing coolant but i dont see it leaking. The res. is low about every 2 or 3 days. when i am driving on the highway and i do about 75-80 for a period of time it sound like a loud fan running and (this amy sound wierd) it smells like water.????? planning on taking it in to dealer.I have 94,000 miles and I want to get it in before 100,000 warranty is up.

Ill post when I find out what they say.

i had the same problem with my 03 6.0 and i replaced the tank and it don't leak anymore i did discover that the alum. peace at the end was pushed out a little.
Trent

I have the exact same problem. I think the EGR cooler is boiling the fluid out. I have stock guages and the temp guage and trans temp guage show normal yet coolent boils out of the resivuior. I run SCT with Spartan tunes on a stock motor (no studs) I know the head gaskets will blow so I have been taking it easy only hitting the horespower for very short runs. This has eliminated the coolent problem so I think you have the EGR cooler causing you to push coolent out. If this is not the problem then you are looking at the head gaskets.

my clutch fan starting coming on and staying on for long periods of time, come to find out my coolant res was low (not seeing any coolant) and i went to Ford for 2 gallons of the gold stuff, poured on gallon in like it was completely empty?? i have not heard it come on since filling it back up. i need to buy some studs and do an egr delete system on her.

Did you try doing a pressure test to the system or tank yet cause that might narrow it down a lil bit. :U:

ok this jsut summed up that I am keeping my 2 7.3's cause I hate the 6.4 and was thinking about a 6.0

thats being a lil narrow minded dont you think??? the 7.3 has their quirks as well, have you ever driven a 6.0? as for the 6.4 with about 2K and DPF delete and Spartan Diesel tunes that 6.4 will prob do more than the 6.0 and 7.3 ever will.

true i might have reacted too quick jhust hard to break habits ive had a 7.3 since my 92

I'll own a 6.0 in a heartbeat... just get some studs, EGR delete, and open up the exhaust, and some tunes and you're rocking and rollin! Earlier ones had some injector problems also, but hell, when something breaks, upgrade it! :choochoo:


The 6.4;s are bad ASS when opened up... I just can't see myself doing that to a truck that is still under warranty for a several more years/ couple hundred thousand miles just to have some fun now...

I have just learned something recently while I'm now in the process of gathering all needed stuff to do my EGR delete and headstud modification/upgrade(should be done in the next 2 weeks:U:)......While all the posts here are true and should be checked....apparently the OIL COOLER is known by Ford techs to cause coolant to blow out of the degas bottle, what happens, in a nutshell, is the oil cooler gets clogged and causes coolant to sit still and along with egr boiling the coolant at the same time and "poof" out comes the coolant, ok so to check this you will need to be able to monitor coolant temp and oil temp, this can be done via scanner plugged into diag. connector....with engine and all systems to full operating temp, the oil temp and coolant temp should not be anymore than 25 degrees different..max..at all times....if the diference between the two exceeds 25 degrees you will see the coolant start to back up and out the bottle...now I have not seen this, I was informed by a good friend of mine who is a Ford diesel tech, I've been lucky and have not had any coolant problems with my 04, hence the mods now...just wanted to share....hope it's helpful.

go complain about the Fords on the Dodge pages. Thanks for nothing!!!

Your truck still running good?? EGR delete fix ya up??

Dude is that really called for....

Ymmot has one and after studs and a tuner it flat rips and hauls heavy aswell. After a few mods the 6.0 can be pretty reliable and a power house aswell.

I had an '05 with all of the above mentioned problems. It started with the coolant coming out of the jug because of the egr and the Edge module, then the oil cooler "blew", then the egr cooler again, then the head gaskets. I got sick and tired of that truck being in the shop so, at 85,000 miles, I traded it for an '06 just like. It's got 60,000 on it now and it hasn't been in the shop yet. I love this truck.

I would rather have a 7.3 seems like all the guys that have 6.0 go back to 7.3

ok guys school me I have had the a 05 ford 6.0 what can you do to make it hold up to a edge exhaust etc so it wont blow coolant and heads and gaskets? mine went threw head gaskets and heads the next year so school me with a positive remarks because i am trying to be open minded

RV i think headstuds are a must ..i'm not sure if you will get around that one???
