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.
