The invention discloses a leak detection method for a double-loop radiator. A dry detection tool is included. The dry detection tool comprises a tool bottom plate; the middle of the tool bottom plate is used for fixing the double-loop radiator, and the two sides, corresponding to the double-loop radiator, of the position where the double-loop radiator is to be installed are provided with positioning check blocks used for positioning the double-loop radiator, fixing check blocks used for fixing the double-loop radiator and a plurality of pressing air cylinders used for pressing the double-loop radiator correspondingly. A first external expansion plug, a second external expansion plug, a third external expansion plug and a side plug are respectively arranged on the outer sides of the two fixed stop blocks corresponding to two pipe orifices of a low-temperature heat dissipation part and two pipe orifices of a high-temperature heat dissipation part of the double-loop radiator, so that the double-loop radiator is
