Abstract (en)
[origin: EP1739293A2] The device has a main coolant e.g. water with freezing-point depressant, circuit (5) with a cylinder head conduit (1), a radiator (8) and a main coolant circulation pump (3). A secondary circuit (9) has a crankcase upper half conduit (2) and a secondary coolant circulation pump (4). The circuit (9) is connected to the circuit (5) by upstream and down stream junctions (10, 11) that are situated on both sides of a non-return valve (6). An independent claim is also included for a method for cooling a heat engine of a motor vehicle.
