While I too like the SCT and believe it is the only viable option when it comes to 6.0's you can push coolant with any of them. Stock trucks do it sometimes. Usually if coolant is pushing out the reservoir it means only a few things, it could possibly be a cracked reservoir tank and/or cap (possible, but not often the case), an ruptured EGR cooler (quite possible), blown headgaskets(also quite possible), or it could have just flash boiled a little bit and overpressurized. It can and does happen, but it wont do it ALL the time. If it's doing it all the time its one of the other three things I just mentioned. Also the Edge products are notorious for killing transmissions in these trucks.

Well that will work for a little while I guess, but is by no means a fix. Some of these trucks will "self-level". Where is your level at now? It should be at the low mark when cold and never any higher. There is a service bulletin out for this. If it pukes every time you get on it, you may have blown headgaskets.

whats ur oil temp and ur coolant temp running ... my oil runs about 30 degrees hotter then coolant temp which means my oil cooler is bad and its restricting coolant to my egr cooler so when it finally reaches my egr cooler it boils the coolant and causes it to puke... this is what i was told by a very respected ps mechanic... i dont no much about these motors but it makes since to me.... so im replacing my oil cooler and doin a river city diesel egr delete... let me no if i was told or am thinking wrong on this

Ryan, that is dead on. Your oil temp and coolant temp should never differentiate more than 15 degrees, if it does, it's a sign of a oil cooler failing. If you're doing an EGR delete now (or any time headgaskets are done for that matter) you should rebuild the oil cooler too.
A coolant filter will help to prevent this as well, since the 6.0 blocks are sand-cast, over time sand deposits break loose and pass through the coolant system and end up in the oil cooler (the oil cooler regulates the temp between oil and coolant). The dieselsite.com coolant filter is around $120 and is worth it's weight in gold.
You're probably just flash boiling the coolant for now, but I wouldn't push it too much more. Do you hear a tea kettle whistle? That is when it's pushing out because of gaskets or egr cooler failure.

Good god mdub I love you you hit the nail on the head. That's exactly what happens!!

The temps y'all are talking about....are those when the engine is fully heated like after driving 10 mins or something?
