I have a part on my 2008 Pontiac G6 GT that I cannot identify. It is connnected to a hard line believed to be steel and believe it to be an inlet for coolant. It is held on with 2 bolts. Located on the front passenger side top of the engine. Please help!!

What you have pictured it the coolant vent pipe./// https://mechanics.stackexchange.com/questions/14711/how-to- change-a-thermostat-on-a-2007-pontiac-g6

that is the link where I found the picture. I did not have my wife's car to take a photo of my own. I cannot find this part anywhere and searching 2008 Pontiac G6 GT coolant vent pipe I had no helpful results

IDK but am a 40 year old as of today and I work on my own vihicles and this part is cracked on my 2009 please im begging someone please tell me what this part is

I have a leak in that general area I believe. But i cant see it from the top, only coming from the bottom. We have same car and trying to see if its the same problem I'm having. Can you see when it leaks? I know around that area is a coolant crossover gasket that are known for leaks in our year car. Have you figured out the problem?

I have the same problem as the flange is split at the top and cannot find the part anywhere. Even the GM parts diagram don't list it. Please let us know if anyone has found what it's called and where you buy it.

It's the engine cool filler tube assembly you can only order from GM
