1. An engine coolant composition comprising:
50% or more by weight of a glycol-based coolant liquid; between about 0.1% by weight and about 10% by weight of a first carboxyl component selected from the group consisting of aliphatic dibasic acids or their salts having from five to 13 carbons, and mixtures thereof; between about 0.01% by weight and about 10% by weight of isononanoic acid; and at least one inorganic acid or its salt as a corrosion inhibitor, selected from the group consisting of molybdates, phosphates, and combinations thereof, wherein the composition excludes nitrous acid or the alkali metal, alkaline earth, or ammonium salts thereof. |
