Where is the water pump located on a Ford Taurus - Mercury Sable?

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.
