A DRAIN CHAMBER SEALING COIN SETTING STRUCTURE FOR A VEHICLE'S ENGINE COOLING SYSTEM AND THE METHOD

摘要

A drain chamber sealing member installation structure of the water pump of car engine cooling apparatus and an installation method are provided to increase the service capacity of the drain chamber by using the coin type sealing member of which the thickness is relatively thin. A drain chamber sealing member installation structure of the water pump of car engine cooling apparatus comprises a drain chamber(12) which can store and dry a coolant leaked in a water pump body(11) naturally. A coin type sealing member(13) is pressed in the leading end of the drain chamber. The coin type sealing member is made of aluminium. The coin type sealing member has a plastic deformation since the tensile strength of member is lower than the strength of the water pump body.
