2011 Cadillac CTS 3.6L water pump and coolant outlet seal replacement

I had a coolant leak that showed up on the floor of my garage so after doing some work to figure out where it was coming from I decided to replace the water pump and the coolant outlet seals. The engine is the GM LLT 3.6L.
This video covers replacement of the water pump procedure and upper coolant outlet o'ring and seal.
