How to service the thermostat on 2005 Mercury Grand Marquis?

Service of the thermostat begins with draining coolant below the thermostat position. First remove the engine appearance cover followed by disconnecting the bolts alongside removing the coolant outlet adapter while pulling out the hose for safe location. The service procedure requires you to first take out the coolant thermostat alongside its O-ring seal from the intake manifold before checking the O-ring condition and replacing it with a new one if needed. The installation process concludes with the opposite order of removal followed by cooling system filling and bleeding.
