The disclosure relates to an expansion tank (1) for a vehicle with dual cooling lines (12,13), comprising a first chamber (2) with a first fluid pressure (P1), wherein the expansion tank (1) comprises a first fluid connector (3) in fluid connection with the first chamber (2) for connection to a first cooling line (12), a second chamber (6) with a second fluid pressure (P2), wherein the expansion tank (1) comprises a second fluid connector (7) in fluid connection with the second chamber (2) for connection to a second cooling line (13), wherein the first chamber (2) and the second chamber (6) are in fluid connection via a pressure actuated two-way valve (9) that acts as a one-way valve open in the direction towards the second chamber (6) at differential pressures between the second flud pressure (P2) and the first fluid pressure (P1) below a first predetermined differential pressure threshold (DP1) and opens also in the direction towards the first chamber (2) at differential pressures above the first predetermined differential pressure threshold (PD1). The disclosure further relates to a coolant system (11) for electric circuits in a vehicle (10) with an electric drive line and a method for filling the expansion tank (1).
