Abstract
A cooling system for an internal combustion engine is disclosed. The cooling system includes a radiator for exchanging heat between a coolant and ambient air, and a coolant pump for circulating the coolant. The coolant system further includes a first set of fluid connection branches between the coolant pump and the engine block, the cylinder head and the exhaust manifold and a second set of fluid connection branches between the engine block, cylinder head and exhaust manifold and the radiator and/or the coolant pump. A first controlled valve intercepts the coolant towards the radiator so that the coolant is recirculated towards the coolant pump. A second controlled valve intercepts the coolant from the cylinder block. A third controlled valve intercepts the coolant from the integrated exhaust manifold.
