A vehicle coolant circuit (20) is disclosed configured to remove heat generated by a vehicle component (1, 11). The coolant circuit (20) comprises a heat exchanger (3) configured to regulate temperature of coolant in the coolant circuit (20), an expansion tank (5), a static line (7) connecting the expansion tank (5) to a first portion (2') of the coolant circuit (20), and an impeller pump (9) arranged in the static line (7). The present disclosure further relates to a hydrodynamic retarder arrangement (10), and a vehicle (30) comprising a coolant circuit (20).
