How to flush radiator and coolant reservoir?
- Thread starter HiveMind
- Start date
Please explain "burp". Thnx
fill it. put the cap on, then turn the bike on for 5-10 seconds. Check the coolant level and repeat until all the air is out.
Do it on the kickstand, not a rearstand and the cap will be at the highest point of the system
I thought when you changed the coolant you were also supposed to flush the system with fresh tap water? Personally I just had my dealer do this for me since they were so cheap while having other stuff done also.
To me in the owners manual it looked like you were supposed to take out the reservoir. Looked difficult to get at to take out.
You can DL a copy of the owners manual here. I would DL to your computer and maybe print a copy out to fold up and keep in a ziplock baggy or so under the passenger seat on the bike just in case needed while out.

Repped and thanked!
16k miles or 24 months, whichever comes first...

I don't think it's been changed since the purchase.....
EDIT:
Called the dealer and they charge $76.50.. wondering if I should just do it myself..

If you can change your oil, you can easily change your coolant. And getting the reservoir out is no big deal. One bolt is a little hard to get to, because of the exhaust headers, but not too bad. Be careful not to over tighten the drain bolt, because it's really small. When I flushed the system with tap water, I just filled the system a couple times with water, started the engine for a few seconds, then shut it off and drained it again. Finally filled with Engine Ice and burped the system as mentioned above.
Make sure you get a new crush washer for the drain bolt (I think it's copper). Don't put the new washer on until you're putting in the bolt for the last time, or else you may wear it out and it will leak.
Changing every couple years is important. I know that in cars the old coolant/water mix can cause corrosion and head gasket failure, so this is cheap and easy insurance.
A note on Engine Ice, too. Any floating things you see in the Engine Ice are supposed to be there. I called them and they said that is normal.

any of you guys have trouble getting the radiator cap off? I turn it all the way off of the notch but the lip of the cap is still catching. any tips?
just fiddle with it... it's just a very tight tolerance and you can "unscrew" it too far, just unscrew, then tighten slightly while lifting.
