    Abstract

    Wet chemistry test methods have been developed to determine the level of alkyl carboxylate inhibition remaining in used OAT coolants. The test strategy of these methods depends on the known alkyl carboxylate ability to protect cooling system metals such as aluminum by forming insoluble metal soaps. Various test configurations make this test strategy suitable for the rapid analysis of used coolants in the field. This paper will document the initial test strategies and the development efforts that led to the first field test for alkyl carboxylate-based coolants. Test kit performance with laboratory and field samples is also discussed.
