04 6.0 coolant problems

i put a new coolant resivoir bottle on in july(due to a small crack in the old one) and in september i started noticing a wining noise coming from the location of the resivoir. every time i checked around the cap was wet, the level is low, and i noticed a wet mark on the hood. so i replaced the resivoir cap because i heard they had a problem with the caps, im not sure if that is true or not, but i have the new cap on it and its not making the whining noise anymore but it is still losing coolant through the cap and i was wondering what is going on with it? i had an idea that it might be the egr getting clogged and making it build too much pressure in the resivoir? i have no idea what is going on with it and i really need help.

thanks,
jon

At minimum it sounds like you have an EGR cooler that has cracked and is cusing excessive pressure in the cooling system and causing it to "puke" out of the degas bottle. It is also possible that you have a head gasket issue. When do you notice the leak? After driving it hard, towing? Is the truck stock?

i can hear the noise while excellerating and when i let off i hear it it briefly no matter how i am driving it. the only thing the truck has is an sct programmer and 4 inch turbo back exhaust. if i did atleast an egr delete it would get rid of the cooler and all.. correct?

Yeah, it would eliminate the cooler but you should still have it checked. When mine went, it also took out the head gaskets. Had 6 of 8 blown.

No, the EGR delete can be done with the cab on.

Take the sct tuner out that p.o.s. Tuner just costme $1000. But i had the exact same problem when i had my tuner in. Im not taking the risk blowing my motor. I justpaid ford $800 for a induction cleaning due to the sct clogging up my intake, and a new egr valve. Ever sincei took the tuner out their has been no cooloant leak

How is the intake being clogged a result of the SCT?

The sct adds more fuel causing more soot build up eventually clogging egr and intake. The sct is way better then the hypertech that i have but now im stock i cant take the chance anymore. But take the sct out for a week or two and you will notice no coolant loss. I called eric at innovative diesel and sct recommends to keep coolant level 1 inch below the min line. But i would rather keep stock and have a motor then overheat / blow something expensive just for more power. It took me mnths to take the tuner out cause it was so addicting to have power. What leveldo you have it on?

I disagree 100%. I've never puked coolant with my SCT and the X-Race tune. He has something else going on causing the leak.
