Coolant replacement

[Hondatechnut12]

Hey guys, I removed all the Tupperware for a coolant change but I'm wondering about the draining procedure? I'm aware to drain the radiator by removing the lower coolant hose and also draining and cleaning the overflow, but I also see the SM shows removing the drain bolt from the right cylinder head. There's a similar bolt on the left side cylinder head aswell? should I be removing that to drain that side? Thanks for the info in advance!!

From what I've read, the additional draining isn't worth the effort. Just flush it well, and fill it properly.

The lower radiator hose is not at the lowest point of the radiator. I used a small vinyl hose and would siphon out what’s left.

I wouldn't bother with the drain plugs. Hassle to access, and the incremental coolant yielded is immaterial.

I removed the cylinder jacket drain screw once . It's tucked away behind the exhaust. It is relatively easy to get off, but getting it back in position to start the thread is really quite difficult. I've never bothered since - the amount of coolant that comes out isn't worth the effort.

Once filled, engine warmed and blipped. Check the reservoir level after your first ride - It may have dropped significantly. You can remove the access cover to get at the filler neck. I use a flashlight. If you can see fluid, it is full. If not, the flaslight shining in will make it easier to see the level from the side.

If you're going to follow the SM, there's only one Cylinder Head bolt, Right Side only. Have fun!
