New Coolant will not circulate after refill, completing successful flush and change - anyone else? Any ideas on what might be causing it?

Ugh! I was thinking I might go the route John mentioned:

"The BMW K1200LT was notorious for getting a big bubble of air trapped if you filled it too fast. The best defense is to know the capacity of the system and measure that amount out first before you start filling. If it all goes in with none left over, you are home free; but if it overflows and you still have some remaining in the filling container, you have an air bubble."

Measure in advance and pour a slow stream. Ugh, if there's a way to screw it up I will.

It's really not that hard. Draining a few ounces from the bleed screw on the right front of the cylinder block fixed the issue for me.

Yep, I'll do my best to remember that. Thanks again for posting your experience.

I suspect this was done after reading the horror stories of what can happen when mixing non-compatible coolant types. I flushed mine 2x when changing mine last time to a different brand.

All coolant, over a long period of time, can turn acidic and start to attack those surfaces it's meant to protect. That is why coolant should be changed at no longer than a 5 year interval. Also to those talking about air bubbles, when you add new coolant after draining the old, add it slowwwwly. Take your time. That way, bubbles won't have an opportunity to form. Always worked for me, Spyder and car.
