I have always had good luck with using the Prestone Flush Kit. This is the one the the "T Connector" for the heater hose and hooks up to a garden hose.
I've used this kit on multiple vehicles and flush plenty of fresh water through system with engine off and with engine running. You must first catch coolant in 5 gal buckets, maybe 2, for proper disposal, but after that, just let the water run.
Then add coolant to achieve 50/50 mix.
