The invention discloses an automobile engine zero-flow cooling system and a control method thereof. An engine water outlet cover is installed at the rear end of a cylinder cover of an engine body. A first cooling liquid control valve is installed on the engine water outlet cover and is connected into a bypass loop of the engine water outlet cover in series. A second cooling liquid control valve is connected into a cooling liquid loop of an engine oil cooler and a cooling liquid loop of a fan heater in series and controls the flowing of cooling liquid passing through the engine oil cooler and the fan heater. A water inlet pipe of a radiator is connected with a connector of the engine water outlet cover, and a water outlet pipe of the radiator is connected with an electronic thermostat. The electronic thermostat is used for controlling the flowing of the cooling liquid cooled by the radiator. The engine heating time can be shortened, fuel consumption of an automobile engine is reduced, part abrasion caused by slow engine heating is also reduced, and the service life of the engine is prolonged.
