PURPOSE: A durability testing device for a cylinder head gasket of a vehicle is formed of closed circuit arrangement and provided to supply a large heat impact to a cooler and a heater of which capacities are relatively small by alternately injecting cooled and heated nonfreezing solutions to an engine in a short time, thereby testing the durability of the cylinder head gasket. CONSTITUTION: A durability testing device for a cylinder head gasket of a vehicle includes a first controller(10) for controlling first and second solenoid valves(12,14) mounted on a nonfreezing solution flow channel(6) introduced into a cooling nonfreezing solution storage chamber(40) and a cooler(44) for cooling the nonfreezing solution stored in the cooling nonfreezing solution storage chamber to circulate, a second controller(20) for controlling third and fourth solenoid valves(22,24) mounted on the nonfreezing solution flow channel introduced into a heating nonfreezing solution storage chamber(50) and a heater(54) for heating the nonfreezing solution stored in the heating nonfreezing solution storage chamber to circulate, and a third controller(30) for controlling a three-way valve(32) mounted on the nonfreezing solution flow channel introduced into an engine.
