Heat exchanger
The heat exchanger is located in a housing which is
integrated with the exhaust manifold and thermostat.
Raw water passes through the heat exchanger matrix
and transfers heat from the internal cooling circuit in
the
engine
(fresh water system) to the outer circuit (raw
water). When the thermostat is closed, coolant is led
through a short, uncooled passage in the heat
exchanger and back to the engine.
