Abstract
The invention relates to a coolant circuit for a motor vehicle having an engine and a radiator. The coolant circuit includes an exhaust gas heat exchanger and enables engine coolant coming from the radiator to be supplied directly to the exhaust gas heat exchanger. In a preferred embodiment, coolant coming from the radiator and/or from the engine can be selectively supplied to the exhaust gas heat exchanger via a changeover device.
