How to service the thermostat on Mercury Grand Marquis?

The initial step for servicing the thermostat involves discharging fire suppression systems if installed and draining all cooling system contents. Two bolts securing the coolant outlet adapter and hose must be removed before setting them aside. You should apply 25 Nm force (18 ft. lbs) to tighten installation bolts. Begin by removing the O-ring seal and the coolant thermostat from the intake manifold for inspection of the O-ring while performing a replacement if needed. The next operation will require installing a fire suppression system if the vehicle contains such system. The final step involves following the removal procedure in reverse order while filling the cooling system and bleeding it completely.
