The engine cooling thermostats are a wax pellet driven, reverse poppet choke type. The thermostats have an air bleed located in the thermostat flange.
The air bleed allows internal trapped air during cooling system filling to be released. The thermostat on the 2.7L and 3.5L engines are located on the
lower left side of engine, near the front. The thermostat on both engines are on the inlet side of the water pump.
The thermostat on the 5.7L/6.1L gas powered engine is located beneath the thermostat housing (1) at the front of the intake manifold.
The thermostat on the 3.0L Diesel engine is integrated into the thermostat housing located at the front of the right intake manifold and is serviced as an

-
Main Valve (4) - Controls coolant flow through the radiator
-
Bypass Valve (2) - Controls coolant flow through the bypass passage to the inlet side of the water pump
-
Vent Valve (1) - Vents the cooling system via a ball valve when it is filled and when the engine is running
