The invention relates to a cooling system (4) for an internal combustion engine having at least one cylinder head (1), the at least one cylinder head being connected to at least one cylinder block (2) by means of a cylinder-bead sealing surface (28). The cooling system comprises at least one first cooling jacket (5) arranged in the cylinder head (1), the at least one first cooling jacket having a flow connection to at least one coolant inlet (27) and at least one first coolant outlet (19), and at least one second cooling jacket (6) arranged in the cylinder block (2), the at least one second cooling jacket being connected to at least one second coolant outlet (20) in the cylinder head (1), wherein the first cooling jacket (5) and the second cooling jacket (6) are connected to each other by means of at least one connection flow path (17), which preferably extends through an opening (17a) in the cylinder-bead sealing surface (28), and a liquid coolant can flow through the first cooling jacket and the second cooling jacket in succession, and wherein the coolant Sow through the second cooling jacket (6) can be controlled by means of at least one first valve (8), preferably a thermostat valve, which blocks the coolant flow through the second cooling jacket (6) in a first valve position and allows the coolant flow through the second cooling jacket in at least one second valve position. In order to enable quick heating of the coolant while achieving optimal cooling of the internal combustion engine, flow through the first cooling jacket (5) according to the invention is possible in a transverse direction of the internal combustion engine. |
