How to service the thermostat on a 4.6L (2V) engine on 2004 Mercury Grand Marquis?

The service of a 4.6L (2V) engine water thermostat begins with drained coolant below the thermostat location. The engine appearance cover should be removed before beginning to remove the bolts that secure the water outlet adapter and hose which need to be placed out of operating range. The technician should uncover the water thermostat combined with its O-ring seal from the intake manifold before checking the O-ring seal and putting a new one if needed. Fitting the installation requires performing all backward steps of the removal process.
