DIY Complete Cooling System Overhaul (Pump, Hoses, & Tank)

I finally reached the mileage where I needed to do this. I took a lot of pictures since it seems like people are always doing this one and are always having questions. Anyways, I hope it helps some of you all out. Let me know if anythings wrong with the writeup, it's quite long so there's lots of room for errors.

There are directions to replace all of the following:
Water Pump
Upper Radiator Hose
Lower Radiator Hose
Expansion Tank and Cap
Temperature Sensor
Thermostat
Coolant
