Coolant leak

[Junior]

2007 rsv. On right side of engine I noticed anti freeze on each cylinder pooling. I removed cylinder covers and found coolant leaking from plugs ? In each cylinder. Help !

Fairly common.  That are line freeze plugs.  Cheap and easy to change.

Why are they leaking ? How do you pull them out to replace and where do you get replacement ?

They leak because the o-ring gets old, so you will need a new o-ring. I believe they just pull out and the cover holds them in place, but somebody else will have a better insight into that.

Thanks

The thread in the center of the freeze plugs is the same as that on the tip of a spark plug with removable tip.  Just thread the spark plug into the freeze plug and pull.

Thanks for information. I ordered 4 new plugs.
