Radiator Flush & 180 Thermostat

My car has been heating up lately and I have never changed the coolant on my car. It has 140k miles and had a radiator replacement when I hit someone at 50k, so I know it must have been changed then. I don't know why it's heating up but I notice my AC sometimes doesn't get cold either...not sure if they're related. I've decided to flush my radiator and change my thermostat to 180. I read on the capacity of my radiator and it says it's over 12quarts or 3 gallons and I can't seem to get all of it out. I unscrewed the plastic cap on the passenger side of the radiator and opened the radiator cap. When I pour water in the cap it does come right out but I suspect there's some in to motor and I see some in the resovoir between the motor and the fan. I've read about a valve I should open to get all of it out, where is that located?

There are two drain plgs on either side of the engine block. Once you take them out all the coolant will empty out. They're white, maybe 1/2" diameter
