Abstract:
An engine coolant additive for use in combination with a major amount of a coolant liquid is described. The engine coolant additive has an alkaline pH, and includes a salt of a monobasic carboxylic acid compound, a salt of an azole compound, and from about 25 weight percent to about 35 weight percent water. The additive may optionally include a transition metal compound such as molybdenum-containing compounds to assist in corrosion inhibition.
