Well, I did a coolant flush and change on my 2015 F3S today.
I cut the Oetiker clamp and disconnected the lower radiator hose to drain the original coolant.
It appeared clean, orange, and with no noticeable contamination.
I then filled it with distilled water, ran the engine without the pressure cap until the thermostat opened and the radiators got hot, and again drained.
I did this 3 more times, filling the reservoir with distilled water each time to get all the old coolant out.
Each time, the radiators got hot in just a few minutes, and everything worked as normal.
Finally, I reconnected the hose with a new clamp and filled the system with Peak Final Charge PRO series mixed with 50% distilled water.
When I started the bike this time, the coolant would not circulate, even though the engine temp quickly went above 205 degrees.
The only difference besides the coolant mix, is that this time I filled the reservoir to the proper level, instead of filling to the top when flushing.
The level was an inch or so below the cold level when I bought the bike, and it never had a cooling problem, but for some reason it refuses to circulate now.
I guess it's possible that the thermostat decided to stick at this very moment, but I wanted to ask if anyone else has had a similar problem.
I guess I'll try tomorrow morning filling the reservoir fully to see if it will help, but I hate to add more coolant just to remove it back down to the proper level later.
If anyone has had a similar experience, what did it turn out to be?
Thanks,
David
