Coolant leak, dont know name of part

[yukonxl1500]

I have a coolant leak right behind the throttle body. I dont know the name of it. I have been searching for engine diagrams so that I can see the part and replace it. Does anyone know where I could get such a diagram or the name of the part. It appears to be some hoses with metal fitting/elbows.

Thanks

i`m not sure but it sounds like one of the coolant lines that are in this thread, maybe the pictures will help you out.
