I always just take a garden hose in every opening until they all run clear. This includes flushing the rad top to bottom, take out T-stat and water top to bottom in engine and then remove the heater hoses and flush the heater core. Then make sure everything is drained and refill with a 50/50 mix. No problem so far for me using this method.
