There is a "Flushing Cooling System" section in co.pdf. It can be difficult to get all of the air out of the system. Pour in the coolant at a rate of <= 2qt per minute. If you have an aftermarket coolant control valve, make sure it is open. When the coolant is full, you can squeeze the upper coolant hose to get some air out of it. Don't overtighten either of the plugs, they are plastic and could break. Changing the o-rings on the plugs isn't usually needed and either is removing the plugs on the engine block.
