The present invention relates to an apparatus to test a seal of a radiator, which inspects a coupling state or cracks in a tank or a core by means of an internal pressure change while maintaining a vacuum or pressurized state of an interior of the radiator. According to the present invention, the apparatus to test the seal of the radiator comprises: an insert member inserted into the unsealed aperture pipe of the tank to maintain the seal of the radiator, wherein one aperture pipe is sealed and an other one is unsealed among the aperture pipes of an upper tank and a lower tank, and guides air from the outside to the inside of the radiator or vice-versa; an air injection/suction module connected to an end part of the insert member, injecting air into the radiator through the insert member or sucking the interior air from the radiator through the insert member when the insert member is inserted into the aperture pipe of the tank; an air cylinder which pressurizes the air injection/suction module to insert the insert member into the aperture pipe of the tank; and a test module which determines the sealed state of the radiator using the pressure value of the interior of the radiator when the air is injected into the radiator, or the interior air of the radiator is sucked. |
