PURPOSE: A jig for measuring a radiator mounting insulator characteristic is provided to conveniently measure spring characteristic value of an insulator through installing the insulator to a hydraulic pressure measuring apparatus. CONSTITUTION: An upper protrusion unit(54) is inserted to a lower hole(22a) of a load cell unit(22) while combining a lower protrusion unit(56) to a support groove(12a) of an insulator(10) centering upon a flange unit(52) of an upper jig(50). A case of the insulator is inserted to an insertion container(62) of the lower jig for combining a fixing unit(64) to an actuator plate(21) by using bolts(66). After installing the insulator to a hydraulic pressure measuring apparatus by using jigs, vibration is applied to the insulator through the actuator plate. Then, the vibration is transferred to the case for being transferred to the load cell unit through the upper jig connected to a rubber material(12). Thus, a spring characteristic value of the rubber material is measured by measuring vibration characteristic applied to the actuator plate and the load cell unit.
