Abstract

The present invention relates to a cooling system comprising a first cooling circuit cooling a first object, a second cooling circuit cooling a second object, an expansion tank, a first deaeration line directing coolant and air from the first cooling circuit to the expansion tank, and a second deaeration line directing coolant and air from the second cooling circuit to the expansion tank. The cooling system comprises further a deaeration valve configured to control the flow through the first deaeration line, a single expansion tank outlet line configured to direct all coolant in the expansion tank to the second cooling circuit and a connection line configured to direct coolant from the second cooling circuit to the first cooling circuit.
