PURPOSE: A coolant reservoir tank is provided to protect a moisture guide groove from contamination by preventing scattering of coolant flowing in the moisture guide groove. CONSTITUTION: A coolant reservoir tank comprises a barrier wall(25) which is extended to one side of a coolant inlet. The barrier wall includes a drain hole(25a) through which air bubbles included in coolant are ejected, and a moisture guide groove(25b) which guides the coolant partly ejected along with the air bubbles through the drain hole. |
