Disclosed herein is an integrated reservoir tank assembly for a vehicle. The integrated reservoir tank assembly for a vehicle includes an integrated reservoir tank in which an inner space is partitioned into a first chamber configured to store cooling water of a first cooling circuit and a second chamber configured to store cooling water of a second cooling circuit by a partition wall; a first electric water pump integrally coupled to the first chamber of the integrated reservoir tank and configured to transmit the cooling water stored in the first chamber along a cooling water line of the first cooling circuit; and a second electric water pump integrally coupled to the second chamber of the integrated reservoir tank and configured to transmit the cooling water stored in the second chamber along a cooling water line of the second cooling circuit.

A cooling system for a motor vehicle may include a first circuit, a second circuit, a first heat exchanger incorporated in the first circuit, and a second heat exchanger incorporated in the second circuit. The first heat exchanger and the second heat exchanger may be flowed through by ambient air and a coolant. The first heat exchanger may be arranged, relative to an airflow direction, in front of and directly adjacent to the second heat exchanger. The first circuit and the second circuit may be fluidically connected to one another at an upstream distribution point and at a downstream collection point such that a part mass flow of the coolant is flowable from the second circuit into the first circuit at the distribution point, from the first circuit into the first heat exchanger, and out of the first heat exchanger back into the second circuit at the collection point.

A deaeration valve includes a housing and a ball in fluid communication with housing. The ball can include a body, a seat defining a bleed passage therein, and a deaeration pin slidably disposed within the bleed passage. Further, the deaeration pin may include a head, a retention feature, and a shaft positioned between the head and the retention feature.

An engine cooling system is provided, which includes a water jacket through which coolant flows, a heat exchanger that cools the coolant, a first bypass passage that bypasses the heat exchanger and recirculates the coolant to the water jacket, a radiator passage that recirculates the coolant to the water jacket via the heat exchanger, and a flow control device that is installed at a location where a coolant passage branches into the first bypass passage and the radiator passage and performs a water flow control to adjust a coolant amount flowing into the water jacket by adjusting a coolant amount flowing through the first bypass passage. A thermally-actuated valve connected with the radiator passage via a second bypass passage is provided to the first bypass passage, and when this valve opens, the coolant flowing through the first bypass passage flows into the radiator passage through the second bypass passage.

A housing has a housing main body and an outlet port. The housing main body includes a cylindrical housing inner wall that defines an internal space therein. The outlet port fluidly connects the internal space and an outside of the housing main body to each other. The valve has a valve body rotatable about an rotation axis along a rotation axis of the cylindrical housing inner wall. The valve is configured to selectively open and close the outlet port depending on a rotation position of the valve. The housing inner wall is formed such that a distance between the housing inner wall and the axis of the housing inner wall varies in a circumferential direction.
