How to service the thermostat for a 3.5L engine on Lincoln MKZ?

The procedure of servicing the 3.5L engine thermostat starts with draining the cooling system liquid. Start by taking away the air cleaner followed by removing the outlet pipe before disconnecting the lower radiator hose from the thermostat housing cover for placement aside. Detach the two bolts followed by removal of the thermostat housing cover and O-ring seal and thermostat. After inspecting the O-ring you should replace it with a new one if needed. Installation of the new thermostat requires engine coolant to lubricate the O-ring seal before securing the bolts to a torque of 10 Nm (89 inch lbs.). Close the system by following the reversal steps of the removal procedure while filling and bleeding the cooling system.
