    Abstract

    Methods and equipment for engine coolant testing are described covering some of the newer standard procedures and proposed additions to the tests used. Methods and equipment gradually evolve according to the needs of the automotive industry. A continuous process is involved in design, safety, operator convenience and test requirements. The ASTM D 4340 test equipment with improvements is discussed. The ASTM D 3147 stop leak test has been substantially revised and updated. A new hot surface scale deposit test procedure and equipment are presented. The ASTM D 2809 test is reviewed with commentary on the current test procedure. Simulated service testing for long-life coolants requires changes to the present D 2570 standard, with consideration of including a more dynamic test similar to European approaches.
