Get a service manual. The process is coveted in detail. I recall roughly, remove cap from radiator, pull coolant hose from water pump to drain. Reconnect coolant hose to water pump, add the required amount of coolant to radiator, run water pump to burp air from.system, top off overflow bottle, replace pressure cap and overflow bottle cap. Done. Something like that, service mannual has all the details.
Assuming you are asking about Rushmore Twin Cooling, not the other liquid cooled bikes.

Changing Coolant in your 2014 - 2016 HD
What I found is the following:
This URL will take you to You Tube. The instsructions provided in the video are right from the tech manual.
From what I've learned from other owners and self mechanics is that is you have a good working knowledge of how things work, go together and how you need to put them back after disassembly you can do this task. Reason is because the disciplene of how, why and because has to be followed.
Spoke some of the HD mechanics and they said yes it works... but you need to start with a cold engine. Not an engine that has just cooled off. one that was sitting over night.
DO NOT START THE ENGINE until you have performed the entire procedure. That means not starting the bike and only turning on the waterpump and fans when your ready. Have patience... it works and it's easy! This video is perfect and follows the manual. I'll be doing this to mine next week.. I'll take pictures and notes and share it
