The invention relates to an engine cooling system. The engine cooling system comprises a high-temperature circulating cooling system and a low-temperature circulating cooling system. The high-temperature circulating cooling system is provided with a large-circulation cooling liquid flow path, a small-circulation cooling liquid flow path and a delay-circulation cooling liquid flow path. An electronic control auxiliary water pump is additionally arranged for the high-temperature circulating cooling system so that delayed circulation can be achieved; the heating requirement of all parts can be better met after an engine is shut down; and the flow direction problem of cooling circulation between different parts is solved.
