PROBLEM TO BE SOLVED: To provide a vehicular engine warming-up device capable of improving collecting efficiency of warm water, and having a thermal storage system. SOLUTION: The vehicular engine warming-up device comprises a heat radiating portion radiating the heat of cooling water, and a heat accumulator 10 storing the cooling water that is warmed up over a specified temperature, in an engine cooling water system. The heat radiation capacity of the heat radiating portion is made to be variable, and when the heat accumulator 10 collects the warm water, the heat radiation capacity of the heat radiating portion is made to be small. The heat radiating portion is a radiator. COPYRIGHT: (C)2004,JPO
