There's usually a drain plug on the engine block, it can be opened normally with out un bolting any thing, if you cant find this on the block consider removal of the lowest coolant hose to drain,
Running an engine flush through the system is a good idea if the coolant has not been changed for a few years (over) , a lot of people dont realize that old coolant actually turns acidic at some point and starts to eat internal Aluminium parts
