Abstract
A coolant circuit for a drive device. It includes a first coolant sub-circuit and a second coolant sub-circuit, in each of which a device to be temperature-controlled is arranged and which are fluidically connected to one another via at least one connecting valve, wherein at least one coolant pump is provided in each of the two coolant sub-circuits, which is designed in at least one of the coolant sub-circuits as a fluid pump having variable delivery direction. The disclosure furthermore relates to a method for operating a coolant circuit for a drive device.
