Did my coolant flush and change today. Let me first start off and say thanks to all the info everyone has posted. Had no problem doing it. The only step I came across that I thought was pointless was siphoning the coolant from the reservoir. I even question this step to begin with but still bought a $5 siphon just in case. The reservoir tube drains into the radiator fill side so once you drain the radiator the reservoir starts to drain. I actually found this out when the first thing I removed was the radiator cap. The fluid from the reservoir overfilled the radiator fill area and drained out into my pan. So really the siphon is not needed. The only other issue that delayed the process was getting a coolant drain plug crush washer. Ended up getting one for a Honda which is the same inside diameter but the OD was just a tad bigger. Worked fine. I flushed my radiator twice so I used a full gallon of distilled water. I'm glad I did because it needed it to remove all the old coolant.
The thing I thought was odd was how much distilled water the system took compared to the amount of coolant I added. A full half gallon of engine ice filled the radiator. Only needed the second half gallon for the purpose of topping off the reservoir.
