How to service the thermostat on a 4.0L SOHC engine on 2008 Ford Mustang?

Service of the thermostat on a 4.0L SOHC engine begins with draining the cooling system fluids. The first step includes removing both the air cleaner outlet pipe and the throttle body. Afterward remove the three upper bolts from the thermostat housing and set the housing to the side while throwing away the old O-ring seal. You should install the new thermostat with 10 Nm of tightening force (89 lb-in). After installing the thermostat, apply engine coolant to lubricate the new O-ring seal. The cooling system needs to be filled followed by bleeding before finishing the process.
