Coolant Loss???

Ok here's the deal, about two months ago my engine was pulled at the dealership, oil leaks. Anyway about three weeks ago I noticed my coolant was at the "min" mark, so I added some, which brought it up midway. Week later I checked again and it was at the "min" mark again, and again I added coolant. So just now I decided to look again and sure's **** it's at the "min" mark again, and once again I added some coolant.

My question is what the hell is going on here? My truck is running great and I don't see any coolant anywhere? I'm getting ready to go on a 1200 mile trip, will I be ok or should I take the car? What gives???

Probably your EGR cooler is leaking. That is common for the 6.0, I won't jump to a blown head gasket just yet, although that is another common failure.

Have you smelled the exahust, does it smell normal or is there a hint on coolant.

The EGR is inside your radiator, if it is leaking then you may be burning the coolant and not know it.

I havn't had too much experiance with the 6.0, the 7.3 is my gig. But from what I have seen, the EGR is usually the cause. Being that you have a tuner, could also point to the head gasket, But that usually does alot of puking at hi power.

Hmmm, well everything seems to be running great, I'm very happy with that. I'm thinking maybe some might be coming out the top of the cap? It's never been below the "min" just at it, is that where it's suppose to be?

Egr cooler is under your intake. Do you still have stock exhaust? If so it is a slight egr cooler leak the coolant is more then likely getting burned off in the cat. It isnt bad enough to actually blow white smoke and water out the exhaust yet.

Now that you mention it, I do remember seeing a TSB about the full mark being wrong on the degauss bottle. But I don't remember if it was lower or higher then the full mark.

I think it moved it down about a 1/2 inch below the min mark. My motor was just apart and I'm really hoping I don't have anymore dang leaks...

And yes I still have my stock exhaust, at least for another week or so. Just bought a new turbo back...
