Motor vehicle cooling system

摘要

A cooling system for a motor vehicle includes an engine cooling circuit in which an engine cooling circuit coolant pump pumps the coolant through at least one engine cooling system and an engine cooling circuit heat exchanger. The cooling system also includes a separate supercharger air cooling circuit in which a supercharger air cooling circuit coolant pump pumps the coolant through at least one supercharger air cooler and a supercharger air cooling circuit heat exchanger. The two cooling circuits are connected with a common expansion tank via ventilation lines which connect each cooling circuit with an upper portion of the expansion tank.
