A COOLANT INFLOW PLUG OF AUTOMOTIVE COOLANT SUBSIDIARY TANK

摘要

The present invention reduces the height of the coolant inlet installed in the auxiliary tank that maintains the coolant filled in the radiator of the car at a full water level at all times, thereby increasing the ability to mount surrounding parts and at the same time improving the watertightness of the car coolant auxiliary tank. In order to provide the cooling water inlet of the cooling water inlet 33 is provided above the auxiliary tank 32 for temporarily storing the cooling water 31 overflowed from the radiator 30, the circumference of the cooling water inlet 33 In the cooling device of a vehicle having a locking projection 35 and a threaded portion 36 to which the coolant injection device 34 is formed, the coolant inlet 33 formed while the auxiliary tank 32 and the coolant inlet 33 meet. Concave forming the annular groove (40) having a diameter smaller than the diameter of the screw portion 36 around the outer root portion of the annular groove (40) is Rimteok 35 is configured such that the.
