Abstract: A vehicle cooling system includes a first cooling circuit having a first operating temperature range when the vehicle is in an operational state, a second cooling circuit having a second operating temperature range, and a degas bottle. The degas bottle has a first chamber operably coupled to the first cooling circuit and a second chamber operably coupled to the second cooling circuit. The degas bottle includes a first chamber operably coupled to the first cooling circuit, a second chamber operably coupled to the second cooling circuit, and a third chamber configured as a common filling chamber for the first and second chambers. The first chamber is operably coupled to the third chamber via a first filling gate, and the second chamber is operably coupled to the third chamber via a second filling gate. The first and second filling gates are configured for simultaneous opening during a fill operation in which cooling fluid is provided into the third chamber to fill the first and second chambers.

The degas bottle has a first chamber operably coupled to the first cooling circuit and a second chamber operably coupled to the second cooling circuit. The degas bottle includes a fill port operably coupled to the second chamber and a flow restrictor disposed at a divider separating the first and second chambers. The flow restrictor is configured to open to enable cooling fluid provided via the fill port, when the vehicle is in a non-operational state, to flow from the second chamber to the first chamber and be closed when the vehicle is in the operational state to prevent the cooling fluid from flowing between the first and second chambers.
