Default 2015 Equinox Coolant Change

I was going to do the 60 month/150K coolant change but haven't found any good information on how to accomplish this. The Haynes manual is useless. Says to drain the radiator & reserve tank and refill. Well you only get 3 of the 8.2 quarts out. The rest is stuck in the block behind the thermostat & in the heater core. I've found some references to a block drain plug near the water pump but the information is elusive. An extensive Google search and nothing useful. Then how about the heater core? Thanks
