This was the congealed coolant that siezed the pump on my '15 Limited...
The system never had anything but factory coolant in it, failed at about 2 years, 20k miles.
Full disclosure... I had never drained/flushed the system, but then... I've never seen coolant congeal either.

Several years ago, GM had a problem with their Dexcool coolant congealing and clogging up radiators.
I had a ZR2 Blazer at that time that needed the radiator changed because of this mess. $800 bill!!
A local repair shop said they change coolant out of GM vehicles weekly and add Prestone.
Is this the problem with Harley coolant?
