摘要

The coolant cooler (7) has a gearbox-oil cooler (5) which is integrated into a cooling water reservoir (6) of the coolant cooler. A second coolant inlet (130) and or a second coolant outlet (20) are provided on the coolant water reservoir to enable the circulation of coolant even when the motor thermostat (11) is closed. The second coolant inlet and or outlet are connected to a thermostat (21). The second inlet and outlet are connected by a bypass line (22), with a branch leading to the engine thermostat.
