One or more techniques and/or systems are disclosed for a new coolant tank that may also provide a structural element to the frame of the engine compartment. The coolant tank is comprised of a rear wall that also makes up a portion of the firewall in the engine compartment. A structural coolant tank component is engaged with the rear wall to form the coolant reservoir. The coolant reservoir can provide support to attach structural elements of the vehicle, and can also allow for improved space efficiency in the engine compartment. Further, improved access to the filling port is provided, while continued operation and desired function is maintained even at extreme vehicle tilt.

A system is provided that may include a pressure sensor coupled to a radiator. The pressure sensor may determine plural pressure readings of a radiator fluid in the radiator. The system may also include a vehicle controller of a vehicle system that includes one or more processors. The one or more processors may repeatedly determine the plural pressure readings of the radiator fluid, and determine a pressure variance of the plural pressure readings that is repeatedly determined. The one or more processors may further be configured to identify a pressure condition based on the pressure variance that is determined.

A control method for an engine coolant valve includes: monitoring an engine driving condition and an engine driving environment; predicting, by a controller, degradation of an engine coolant based on the engine driving condition and the engine driving environment by a controller; changing, by the controller, an opening of an integrated flow control valve when the engine coolant is predicted to be degraded; and generating, by the controller, a coolant exchange alarm when the engine coolant is predicted to be out of a control range and degraded.

A coolant circuit for an internal combustion engine includes: a coolant pump; at least one coolant line; a radiator; and a coolant cavity delimited in the internal combustion engine. The coolant pump, the coolant line, the radiator and the coolant cavity are filled with a coolant. One or more sensors, configured to monitor the coolant concentration, are fixedly and permanently arranged in and/or on the coolant circuit.

A diagnostic apparatus for a coolant control valve including a housing having a plurality of ports, a valve member provided to be rotatable in the housing, and a driving device rotating the valve member between two end positions, the diagnostic apparatus including at least one position sensor provided on an external surface of the housing for sensing a position of the valve member, a determination device for determining whether or not the valve member is stuck using the position of the valve member sensed by the position sensor and a controller for controlling the driving device.

A cooling system for a vehicle is provided. The system includes a valve that is disposed at a predetermined position in a cooling channel to discharge bubbles produced in a coolant out of the cooling channel. Additionally, a controller is configured to detect whether bubbles have been produced in the coolant using a rate of pressure change based on a temperature increase in the cooling channel and open the valve in response to detecting that bubbles have been produced.
