Coolant Outlet: Description and Operation

Coolant Outlet Duct





A plastic coolant outlet duct connects to the outlet port of each cylinder head providing a common connection point for the radiator top hose. It also incorporates the ECT sensor - providing an input of coolant temperature at the cylinder heads - and the supply to the air-conditioning heater matrix as well as the bypass flow to the thermostat housing. An in-groove gasket seals each of the outlet-to-cylinder head joints. An aluminum gasket seals the ETC sensor to duct joint.
