look for the serpentine belt. this is a belt that has a long trail around many pulleys (Power Steering pump, alternator, water pump, AC compressor and a tensioner) and is about 1 inch wide give or take a 1/4 inch. your water pump has a hose coming out of it going to the radiator and another smaller one about the thickness of your thumb going to the firewall. The firewall is the sheet metal behind your dashboard. That small hose goes to the heater core so you'll have heat in the cabin area. if you still can't find the water pump back-trace the hoses from your radiator until you come to it. One caveat is that some Ford/Mercury models have the pump practically built into the engine while others stick out like a sore thumb and are bolted to the side of the engine. You really can't miss as it is the only thing with large rubber hoses attached to it. The only other pump device that runs off of the serpentine belt is the power steering pump. That one is easy to find b/c the rubber hose that goes from the power steering fill-up container should have power steering fluid printed on it. Follow that rubber hose which should be small, and you'll find the steering pump. The only thing left with hoses attached to it is the water pump.
You run the engine till warm then look underneath and see if the pump is leaking. A faulty pump leak is very visible in Taurus/Sable.
depending on your ability to get good deals for 3.0 litre new pump 40 to 70 dollars gmb is a good lasting replacement
The water pump is on the center of the passenger side of engine. It is hard to see with the Radiator/windshield washer reservoir in the way. It is driven by the pulley below the alternator pulley and has the lower Radiator hose attached to it. UPDATE... JUST BE ADVISED, YOU WILL HAVE TO REMOVE THE ALTENATOR AND PROBABLY THE POWER STEERING PUMP AS WELL.

On a 2002 Mercury Sable : The engine coolant reservoir is at the front of the engine compartment , on the passenger side of the engine compartment ( the engine coolant reservoir has a thread on cap on it , that is your pressure cap / radiator cap )
You look under the pump and see if it's leaking. It's very obvious if it is.
no. instead use arm and hammer washing soda diluted with hot water
