ABSTRACT:
An engine cooling system comprises a coolant inlet formed at one side of a cylinder block for allowing a coolant to separately flow into the cylinder block and a cylinder head, and a coolant outlet formed at the other side of the cylinder head for allowing the coolant having flowed into the cylinder block and the cylinder head to separately flow out of the cylinder block and the cylinder head. The coolant outlet is formed diagonally opposite to the coolant inlet. The coolant delivered from a water pump separately flows into the cylinder block and cylinder head, whereby a cooling efficiency of the engine is improved.
