Ok, had the P0299 come on. 2nd time it came on. Came on once before then went off. Dealer said they couldn't do anything the first time. Came on again and they replaced the turbo. Get the car back and it over heats. Take it back to the dealer. Of course they can't make it over heat and they have had the car 4 days now. It's been 97 degrees the last couple of days so if it is not going to over heat on a day like that it is probably good. My best guess is an air pocket in the cooling system and it worked its way out. This is also the 2nd time this dealer gave me the car back after warranty service and it over heated. So yeah, this is obviously the last time I deal with them. I am now worried that I am going to have more issues down the road because of the 2 overheating issues. Luckily both times we were local and were able to get it right to them.

Anyway, for changing the turbo, I thought I read where they have to drain the oil to replace the turbo? If that is true, then they put the old oil back in. Or maybe it was the coolant they have to drain which would explain why it could have gotten an air pocket or whatever happened to it.

Sorry for the rant. Just not happy with them. Unfortunately next closest GM dealer that is not owned by the same company is about 30 miles away.

Assuming you're talking about the gas turbo (as opposed to the diesel). Not sure if it makes a difference regarding your question but they do have different turbos.

From what I've read here the gas turbo bearings are lubricated with engine oil and cooled by a line from the coolant system. I don't claim to be a mechanic but surely those lines would have to be disconnected in order to R&R the turbo which could introduce air in the line.

I have pulled my turbo multiple times. You have to drain the coolant. The oil return is gravity fed, so no need to drain the oil since the second you turn the car off it ends up in the oil pan.

The process to refill the coolant is a "little" time consuming. I use the term loosely, because it is about 20-30 minutes and depending on the dealership they may not have taken the time to do it correctly. You fill it up, let it get up to operating temp, and then top off as necessary. I could see them filling it up and calling it a day. Then when you brought it back in they could have just filled it and not said anything. Of course this is all just speculation.

Thanks for the info. So far so good on it. No heating issues. It does run better with the new turbo thats for sure. I will probably replace the spark plugs shortly as well.
