Did you tighten the coolant heater hoses when you removed your egr cooler?

 

[06dmax]

Yes that is tight and not leaking

you're probably just smelling what you spilt. i know under my hood stunk for several days after i pulled the coolant drain plug and got that shit everywhere.

 

[06dmax]

Okay good that's what I want to hear

Yeah I wouldn't worry about it.. Could be a injector cup leak, but dont think that much into it, prolly just an air pocket and left over coolant spill!

turns out to be head gasket on pas side at the back of the motor dripping anti freeze im pissed!!!

Mines doing the exact same thing. I think its the HG, but still hoping it might be something else. I'm gonna tear into it and check all the other possibilities tomorrow i think.

The LB7 engine is the only one with injector cups. The rest were machined into the head for injectors.

I've got an 06 LBZ, too, and mine is puking antifreeze from the overflow tank. I'll let it cool off, fill the overflow again. Then drive it and it takes awhile for the temp to come up...longer than normal and heater blows cold. Then after about 10 mins of driving, the temp spikes up past normal for just a few seconds then levels back off where it always ran, heater starts to blow hot and at same moment my computer comes on and says "Low antifreeze level."

I just had someone put a new EGR valve on it and clean the ducts around it? I was getting an EGR Insufficient Code, so I took it in and that's what he said needed done. Just after I got it back from that service, the antifreeze puking and crazy temperature issues started.

Any ideas?

Thanks,

Chris

Head Gasket(s) are blown for sure. Been there, done that, 3 trucks... Lame.

You're right. Mechanic just called me today. Says it's a 30+ hour labor job!! Holy smokes! Says should cost me $5K. Does that sounds right? I trust this guy a lot and consider him a friend, so I'm sure it's right, but WOW...seems like you could built a new truck in 30 hours.

Thanks.

There is alot to it,5gs seams pretty steep but i do believe thats what GM says it takes is 30 hours.Maybe someone in your area from the forum can help out,save you some cash and put a little in there pocket at the same time.I would get parts yourself from Darryl or Henry from creatures of the night.that may save you some rite there

Mine too leaking same damn place. Number 8 inside combustion chamber and down block. Pulled motor and finally got all the bolt on shit off of it. Going back w injectors to stock trim. Lame for you sorry dude. Mine would smoke the street out at take off
