The application discloses a kind of detection method, device and equipment of the cooling liquid filling quantity of engine cooling system, comprising: filling cooling liquid to the expansion kettle of cooling system to the highest mark line position;Multiple control starts engine operation and after engine each operation stops, re-filling cooling liquid to the expansion kettle to the highest mark line position, until engine operation stops, the cooling liquid level height in expansion kettle is stabilized at the highest mark line position;The amount of cooling liquid filled in the expansion kettle each time is accumulated, to determine the cooling liquid filling quantity in cooling system.In the present application, cooling liquid is directly injected into the expansion kettle, and the engine is started multiple times, and cooling liquid is filled and supplemented when the engine stops each time, until the cooling liquid in the expansion kettle stabilizes at the highest mark line position, i.e.The filling quantity of cooling liquid in the cooling system can be accurately determined, to provide more accurate and reliable data basis for engine matching vehicle, which is beneficial to ensure the working performance of engine operation.
