6.0 overheating- gaskets?

so i have the basic three mods, intake exhaust and chip, yeah the superchip isnt as good as the sct i will upgrade to one when i go further with my truck. so heres my question.
I am having intermittent overheating problems, not holding coolant all the time either. No matter the tune whether stock, economy or high power. I will find myself at a stoplight or in the drive way in park, with the ac on, and look down so find my oil needle near redline temperature. I can drive it around, and the temperature will eventually go down. I have checked the coolant when engine was cold and added enough to fill the coolant bottle back to normal, but after driving a few days it goes back to "intermittent overheating". I also have the EGR block off plate installed. My guess is head gaskets are on their last limb. Just seeing what the general consensus was.

Re: 6.0 overheating- gaskets?

Oil temp going up? Scan it and see the difference between EOT and ECT.shouldn't be more than 15 deg. Is there any oil in your coolant?

Re: 6.0 overheating- gaskets?

Noticing any white smoke from the tail pipe? Are both side of the cooler blocked off or just the exhaust side? Sounds like you need an oil cooler/egr cooler. HG's are a possibility

Re: 6.0 overheating- gaskets?

Just because ur truck is over heating doesn't mean HG, like stated above is ur egr cooler still in place ? Could also be oil cooler failing, how much coolant are ur loosing ? Is the truck excessively puking ? Also drive it stock n any notice in smoke color ?

Re: 6.0 overheating- gaskets?

when my head gaskets went.... those were the symptoms.... new head gaskets and studs, no more overheating issues.... I am not saying its your problem.... Ia m just saying it was mine. I had already deleted my egr, put new injectors in it and did a bunch of other work, so I kinda knew it was time for some studs and gaskets....... if it is the case, make sure you get the heads done at a good machine shop.... and also put a coolant filter in there while your at it....

Re: 6.0 overheating- gaskets?

Make sure you check the basics before getting too excited about an EGR or headgasket problem.

Is the water pump OK?

Is the thermostat OK?

Is the fan clutch working properly?

These are questions I'd want answered before looking at $$$$ EGR or HG repairs.

Re: 6.0 overheating- gaskets?

i would def. recommend a coolant filter kit, its a small price to pay for the preventative maintenance and not having to worry about plugging your oil cooler.

Re: 6.0 overheating- gaskets?

first off thanks for all the fast responses.

No, there is no white smoke coming from my stack. Even when being driven. I have blown one egr cooler before and it was replaced along with an updated hpop. Just the exhuast side of the cooler is blocked off.

Yes, the oil and egr coolers are both in place. The truck does not excessively puke until underload for a period of time (given that you filled the coolant bottle before you left) in which it would begin to overheat in cycles. By cycles i mean the needle would pin, my electric fans come on and as i spool the turbo in neutral it brings the temps down. If i dont touch it it continues to climb.

It is a problem that comes and goes and I thought that the egr plate would elminate what I thought the egr was causing.

any help is appreciated. I have recieved two quotes of 1800 and 2500 in labor to do headgaskets, not including the studs. Sure would be nice to be sponsored by a machine shop.

Re: 6.0 overheating- gaskets?

If only the exhaust side of the egr cooler is blocked off, and the cooler blows, coolant will still enter the intake through the egr valve causing your symptoms. If your losing coolant as fast as you say and you have no leaks I guarantee there is white smoke coming out of your exhaust, your just not noticing it. You can try pulling your egr valve and looking down in the intake, if it looks wet then the cooler is more then likely blown.

If all seems well in that area then the proper way to do it is pressure test the cooler off the truck, if it passes you need HG's. Can't rule out the possibility of it being both too

Also I'm not sure if you have a coolant filter or how clean you keep you oil but I'd bet you probably need an oil cooler as well, they just don't last once you start to rack up miles. I'm on my 4th

Re: 6.0 overheating- gaskets?

We have had two of these with the last to weeks, with a intermintent overheat problem, 2003 and 2004. Both of them ended up being the waterpump. They have plastic impellers on them and both of them were cracked from the center out, just free spining on the shaft. We are in the R&D stage of making a billet impeller right now. This will solve the problem of the plastic impellers breaking.
