The invention provides an automobile engine cooling system which comprises a water pump, a cylinder cover water jacket, a cylinder body water jacket, a first thermostat, a heat radiator, an electronicwater pump, a supercharger, an expansion tank, an engine oil cooler, a second thermostat, a fan heater and an engine degassing pipeline, wherein the opening and closing of corresponding pipelines ofthe engine oil cooler and the fan heater are controlled by the second thermostat; after the supercharger is shut down, the electronic water pump carries out delay cooling; and the flow rate of each loop is about 30 L / min, so that the requirements of the engine oil cooler and the fan heater are met at the same time. With the adoption of the engine cooling system, the friction is reduced, oil consumption is reduced, the requirement on water pump performance is lowered, the combustion efficiency is improved, and the reliability of the supercharger is ensured.
