Coolant Flush Help
Hey, just picked up a 2003 919 and decided to do some minor preventative maintenance on it. I started with an oil change which was easy and straight forward and then decided to flush the coolant. I read on how to do it in the service manual and looked up a video on Youtube, ...seemed pretty easy. I moved the tank up, opened the coolant fill cap and the reservoir cap, pulled out the plug bolt and drained all of the coolant. Used a siphon to get the reservoir coolant out. Ran a garden hose through the system until I was getting clean water out the other end, then used about a gallon of distilled water to flush it through.
This is where I get a little confused from the guide I was following, they said pour coolant into the reservoir container, run the bike for 2-3 min then top off the container as it should have sucked the coolant to fill the system, then repeat this a few times. When I tried this, nothing! The container stayed right where I left it. I tried opening the cap under the fuel tank and then ran it for 2-3 more minutes and still nothing. ???
I then decided to fill the system through the cap that is under the fuel tank, got about 1.5 quarts in there, and 1 quart in the reservoir. The manual says 3.2... What am I doing wrong?!? Why isn't the reservoir being sucked dry to fill the rest of the system?
Any help would be awesome!!
