An expansion tank is disclosed in which a non-return valve is fitted in an outlet port of the expansion tank to limit backflow of coolant into the expansion tank in the event that the pressure in the expansion tank falls below the pressure in a return conduit thereby preventing the expansion tank from filling with coolant. The non-return valve and the expansion tank are formed as a single component and the non-return valve is located in an outlet port of the expansion tank.
