A RADIATOR PRESSURE CAP FOR A VEHICLE'S ENGINE COOLING SYSTEM

摘要

PURPOSE: A radiator pressure cap structure of a vehicle engine cooling system in an air opening manner is provided to improve the impact safety of a vehicle by contracting a bellows formed on a neck part. CONSTITUTION: A radiator pressure cap structure of a vehicle engine cooling system in an air opening manner comprises a bellows. A radiator pressure cap(12) is projected from the upper part of a main body(11) of a radiator(10). The radiator pressure cap is positioned at the lower part of an engine room hood(20). The neck part of the radiator pressure cap is formed of the bellows. The bellows can be contracted by the impact load from the outside.
