This is incomplete in that it doesn't mention backflushing the system by using Prestone's own "Flush N Fill" kit on the heater hose near the firewall. It's odd that they leave that out.
You can't "drain the entire cooling system" by just draining the radiator, especially if the thermostat is closed on a cooled-down engine. The same applies even if the thermostat is open (or removed) with the engine off and there's no water pump or garden hose pressure forcing out coolant against gravity.

@shaocaholica they used a general motors vehicle which used dex-cool. this is gm's "own" coolant and shouldn't be mixed with traditional green.
