Coolant Outlet: Description and Operation
Coolant Outlet Duct
A coolant outlet plastic pipe connects to the outlet port of each cylinder head to provide a common connection point for the radiator top hose. It also
incorporates the Engine Coolant Temperature (ECT) sensor which provides a signal representing coolant temperature at the cylinder heads. The outlet
pipe has connections to supply the heater matrix and 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 ECT sensor to duct joint.
