Am gonna change the coolant on a 2017 800 gs.
Can’t seem to find the drain plug, surely you don’t just pull the bottom hose off :confused:

Not the best vid, as it doesn't show the action, but it explains the procedure sufficiently.

Personally I am lazy these days & leave coolant changes & brake fluid to the dealer. Service costs on the F bikes seem pretty reasonable, relatively speaking.
 
You remove the lower pipe from the side of the heat exchanger. There is also a drain bolt on the front of the block but I didn't use it as the pipe is lower.

Thanks, I still can’t find the drain bolt though :nenau

You don't need the drain bolt. The BMW service manual says to drain by disconnecting the pipe at the heat exchanger. There is a bleed screw on the right side of the engine. I used a vacuum filler and it was a breeze. Some not using said tool have had air entrapment issues.
