How to Change the Thermostat in a Mercury Villager

The second generation Mercury Villager came on the scene in 1999 through 2002. It featured a reasonably powerful 3.3L V6 engine, and was available in base, luxury and sport models, all boasting improved ride and handling as well as thoughtful cabin ergonomics. A Villager in mint condition is worth a look for the used vehicle buyer. The following steps detail the installation of a new thermostat in those models.

Instructions

1

Disconnect the negative battery cable from the terminal. Drain the cooling system so that the level of coolant is below the level of the thermostat.

2

Remove the thermostat housing and set it aside. Lift out the thermostat.

3

Set the new thermostat in position. Make sure the jiggle valve is in the upright position. Replace the thermostat housing.

4

Refill the cooling system with the appropriate type and amount of coolant. Replace the radiator cap securely.

5

Reconnect the negative battery cable to the terminal. Start the engine and allow it to run for several minutes to warm up. Check for proper operation.
