Under the front of the car are two plastic covers to keep dirt from getting up into the engine compartment. Remove the one on the passenger side. The coolant drain plug is on that bottom corner of the radiator. It looks like a wing-nut. Please be gentle because it is just plastic and can easily brake.

Were is the drain plug on block

You could try draining the coolant from the bottom of the radiator, rather than the block.
If you can not find a coolant release valve, try removing the hose from the lowest connection of the radiator.
Make sure that you take the cap of the expansion bottle (or radiator) to ensure that air can enter to let the coolant out.

I have a 1997 civic dx and it has a sputtering from engine

If you haven't done a tune up within the last year, it's time to do so. Check your spark plug wires, they may be bad already and arcing inside the engine block causing a missfire. Also, replace the plugs, cap and rotor.
