  • Patent number: 10899952
    Abstract: An automotive engine coolant composition includes: a non-silicone surfactant; an anti-foaming agent containing a mineral oil and silica; and a base, in which the base includes at least one alcohol selected from the group consisting of a monohydric alcohol, a dihydric alcohol, a trihydric alcohol, and a glycol monoalkyl ether and/or water, a kinematic viscosity is 8.5 mm2/s or more at 25° C. and 2.0 mm2/s or less at 100° C., and with respect to 100 parts by mass of the coolant composition, a content of the mineral oil is 0.01 to 0.4 parts by mass and a content of the silica is 0.003 to 0.1 parts by mass.
