Easiest way to flush coolant?

I've seen some posts but I wanna know the quickest, most thorough, most effective, fewest extra tools, and cheapest way. If those are mutually exclusive please add your thoughts. Has anybody found a better, less expensive, silicate-free coolant that Honda's at $14 a quart?

O'reilly's sells a coolant that is Honda approved for about $20 a gallon.

I don't know if there are any faster ways, and I don't honestly recall the procedure offhand (only did it once so far) but I just followed Fred Harmon's video and all went well. One thing I remember for sure - it took a loooooooonnnnnggggg time to get all the fluid back in - that part's a slow process.

If I ever do it again I will wet -vac the coolant out of the reservoir/ overflow tank. The feeder tubes were very very short and the room to maneuver was very very small.

I did you use a manual oil change pump that you use for the dipstick for the coolant bottle, sucked it out put some water in and repeated a couple of times. As stated above refilling is the slow process.

You lips move but I can't hear what your saying

Is that the tank at the bottom on the left side or up top under the right pocket? Because I thought of THAT on my own and was hoping someone would confirm that it's possible to open a cap somewhere and SUCK IT OUT! Tell me more...

So... Tell me more. You drained or sucked only? Why did replacing it take so long? Do you run the engine during the process to circulate and break up globs or loosen corrosion? Just wondering.

I need to drain it, flush it really well, and refill. My wing has 110,000 miles and I put 65 of those on it and I have NEVER flushed/changed it! I know I'm a bad person for not doing it.

That's the plastic tank under the bike, of which I speak. You have to drain the coolant via the drain plug located behind the lower front cowl.

If you are going to keep the bike until it is truly worn out you might look at Evens coolant. It is a life of the engine coolant replacement that is claimed to perform and protect better than other coolants. I put it in my bike this year but haven't done any extreme , for me , riding this year. Did do a couple of rides were I was stuck in traffic in high 80s low 90s with out any issues but that is it.
