Need help finding the "block drain plugs" on the 3.5 engine for 1997 Chrysler Concorde.

I'm refering to a haynes repair manual to flush the coolant of my 1997 Chrysler Concorde. Following the step by step directions, I have located the drain **** that resides at the bottom of the radiator (step 25.5, gives an illustration). But then the next step, after you open the bleed valve screw, is to "remove the drain plugs located behind the exhaust manifolds on each side of the engine block". Anyone familiar with the chrysler concorde 3.5 engine know where I would find these drain plugs? What do they look like? The manual does not give an illustration, it is step 25.7.

 

Try searching the internet for images of "engine block drain plug" and take a look at what comes up. Then crawl under there and look "behind the exhaust manifolds" and you will find what you are looking for.
There is an easier way to flush the cooling system. Get a flush and fill kit from the local autoparts store. You cut a heater hose and insert the "T" fitting from the kit in the heater hose. Connect a garden hose and the old coolant is pushed out. Follow the directions in the kit to fill with new antifreeze. Be careful to run the city water at low pressure/flow rates so you don't blow the seals of your water pump. Full city water pressure is several times the pressure that your cooling system was designed to run at so you need to be careful with it.
