BEFORE YOU DO THIS: Be aware that if you are doing it because of a a knock sensor code, it is most like uneccesary. A knock sensor is a passive device that has no effect on normal engine operation. Mercury Villagers are notorious for throwing knock sensor codes when nothing is in fact wrong with the knock sensor (which produces no current under normal conditions). Because of the way emission components are wired, problems in front oxygen sensor wiring harness (common) or the throttle position sensor can also cause this code to be set. Many of these sensors are replaced uneccesarily. Know also that this is a fairly involved job which will take the better part of an afternoon if you are fairly skilled. You will need to drain and refill the cooling system, and you will be disassembling a number of pipe connections that have to be reinstalled with either aftermarket gaskets or assembled with RTV, which can be tricky to get right without leaks.
Here is the procedure for replacing the knock sensor on a '01 Mercury Villager:
--Removal--
1. Remove the lower intake manifold.
2. Disconnect the heater core hose from the coolant crossover tube. (refer to the diagram in the 'related links and sources' portion of this answer) Release the clamp and disconnect the hose.
3. Release the clamp and remove the lower radiator hose from the coolant crossover tube.
4. Remove the water bypass hose from the thermostat housing. Release the clamp and remove the hose.
5. Remove the coolant crossover tube. Remove the bolts and tube.
6. Remove the Knock Sensor (KS). Disconnect the electrical connector. Remove the bolt.
--Installation--
1. Install the knock sensor and bolt. Connect the electrical connector.
2. Install the coolant crossover tube. Position the coolant crossover tube. Install the bolts.
3. Install the water bypass hose. Position the hose. Position the clamp.
4. Connect the lower radiator hose to the coolant crossover tube and position the clamp.
5. Connect the heater core hose to the coolant crossover tube. Connect the tube. Position the clamp.
