Re: Coolant Flush
Nothing, they will mix fine.
I open the bottom hose connection and let it all drain (with the cap still on), one most of it is gone then I loosen and remove the cap, that little tiny bit of vaccum keeps the water from pouring out. Also unbolt the plastic reservoir and spill anything out of there. Clamp the hose back in and then I fill the system back up with a 50/50 mix of water and white vinegar. Top it off and get most of the air out. Start up the bike and let it run up to the fan coming on. Then turn off the bike and let it sit for 1-2 hours.
The vinegar will help disolve and loosen any mineral deposits in the cooling system and help flush them out. After 1-2 hours have passed, drain the system again like before. Then refill it with distilled water, start it let it come up to temp a little and turn it off and drain. Keep doing it another 1 or 2 more times until whats draining out is nice and clean and clear. At that point you've drained out the majority of the old junk in there. Finally refill and bleed the system.
BTW, why are you putting engine ice in your bike?
