Radiator

Cooling Radiator

The radiator is made from aluminum and is divided into a high-temperature section and a low-temperature section by a partition wall (see coolant circuit diagram). The coolant first flows into the high-temperature section and then back to the engine, cooled.

Some of the coolant flows through an opening in the radiator partition wall to the low-temperature section where it is cooled further. The coolant then flows from the low-temperature section (when the dwi thermostat is open) into the oil/coolant heat exchanger.
