I used tap water for flush, then distilled for filling so I didn't need to buy so many gallons of H2O.
Just disconnect the top hose from the overflow bottle and put its end into whatever container you plan to trap the old water in (I used a 5 gallon bucket)... the hose should be able to reach out of the engine bay, over the grill. Have plenty of fresh water ready to fill into the overflow bottle as it starts to pump out the hose (take off cap and use a funnel, I cut the bottom from a 1 gal. water jug).... continue until only clear water exits hose (good time to add flushing detergent and replace hose to the bottle for 15-20 minutes, then re-flush)... whether you use detergent or not, once a couple of gallons of only clean water comes out, add 1/2 - 1 bottle of antifreeze, depending on how much you need in the winter... when water starts coming out green, put the hose back in place and fill to max with water... let it cycle through and adjust as needed... check the level the next day before you start it.
All told, I had about 5 gallons of dark waste water, about 5 more of medium colored until it started turning clear...
If you want to back-flush, this technique is not the way to go... this is an easy-way.
I'm a bit unclear on this. Do you just disconnect the top hose, run it into a container, then run the motor to pump the coolant out while replacing through the reservior? If so, seems like a very easy way indeed. Of course, I need to replace my water pump and will try to back flush the system when I have it off.
