Puking...?

[TheFordman87]

So I know if your truck pukes coolant that it's a big sign that the head gaskets are blown. But why if your running down the interstate running it hard a couple of times would it blow all of the coolant out of the tank? I can see it puking some but the whole tank...? Any thoughts? The truck is under warranty so if it needs new gaskets no biggie. But I will beg them to let me pay for ARP head studs if it does have to have Head Gaskets done.

If it's blowing the whole tank empty it's either the Egr cooler or the headgaskets.. Egr cooler because it will all flow into your exhaust and headgaskets because it will push combustion gasses into the cooling system and therefore over pressure and overfill the system with gas... Only place for the gas and fluid to go is out the cap

Sounds like head gaskets pressure created by combustion is being pusshed into your cooling system and pushes past the 16lbs the cap is designed to hold.

I'm thinking it is as well but maybe just a little bit that's why it only does it maybe when running it down the highway and running the crap out of it. It's okay though I'm going to take the truck in probably this week and have them put new head gaskets on it if that's the problem cuz the truck is under warranty still. I just hope they will let me pay for arp head studs and they can do the work. I will keep my fingers crossed though.
