Coolant under hood

So I took my truck in to get my turbo checked under warranty, they said the vanes were sticking, they cleaned it up and it worked good. I took it home and the next day notice the turbo isn't boosting again. Also noticed loss of power so I looked under the hood and noticed coolant all over the right side of my engine compartment all around the degas bottle. I took the truck back in today and they said they should know what's wrong today. Other than the turbo bring bad, what's with the coolant all over the inside of my engine. Anyone experience this? My truck has 61k miles but got warranty to 100k.

I think your head gaskets are shot. If they are MAKE sure you get the heads checked and do ARP head studs!!!!!

Dealer called, guess there was a hose that came off my aftermarket gauge that made me lose turbo boost. The cap on the degas bottle was bad they said and that was the cause of the coolant under the hood. Guess it was a quick fix.

Well, I popped my hood and was about to do the zoodad mod and sure enough, there is coolant all over everything AGAIN. Obviously it wasn't simply a bad degas bottle cap. This pisses me off cause I simply don't have the time to drive back and forth from the dealer. Could this be a gasket issue? No codes or check engine light. Seems to be running fine, maybe EGR cooler?

sounds like the EXACT same problem I was having. Ended up being the head gaskets anyway. Before this the oil cooler and egr cooler were leaking. Had them repaired, it kept puking all over the driver's side of the truck so next was the head gaskets, NO CEL, no funny noises....just tons of coolant loss

I'm not losing coolant like crazy but pressure is definitely sending it all over the driverside engine compartment. I have driven it and check and no fresh loss, seems like it's occasional back pressure causing it to pressurize out. I was hoping for some more feedback cause I really don't want any more trips to the dealer. I called the service manager and they said they pressure tested it around the city last time when they replaced the degas bottle cap and it tested out fine. They said next Monday they will take it on the freeway and get the RPMs up and check the pressure then. Hopefully they find out, I'm tired of popping my hood and seeing white **** everywhere.

When my HG blew my cab heat was also intermittent - when accelerating it blew cold air when there should have been heat, when idling, heat worked fine. From what I understand, the coolant system is getting air bound due to the excess pressure in the coolant system with blown HG. This is a simple test that might help diagnose.

If it is your head gasket, make sure to get the heads machined and pressure tested and try very hard to get the dealer to put in ARPs and do an EGR delete kit to help with the reliability of the engine.

Good Luck

Mine was more dramatic I guess. I would drive it around, and it would take a LONG time to get up to operating temps, I'm talking like 20 minutes. then I would get home, check the overflow and it would not show ANY coolant. When I filled it to minimum though, and drove it, you could smell the coolant puking out and the evidence was there under the hood. Coolant all over the place.
