changing/flushing coolant (please help)

[StegsRide]

ok i searched and i cant find much info on this.
i already got the radiater drained but the haynes manual says you need to drain coolant from the engine block. it says to remove the drain plug or knock sensor

so my question is where is the plug or knock sensor?

i think i found it but its looks like a pita to get off. i hope its not it.

To avoid that, I just started up the motor and used the garden hose to run water into the radiator, left the drain open and ran a bunch of water through, then closed it and filled it up, drain it, fill it up, drain it...Seems to have gotten all the rusty crap out.
