This volume consists of 14 manuscripts from the Fifth International Symposium on Engine Coolant Technology sponsored by the American Society for Testing and Materials Committee D15 on Engine Coolants, held in Toronto, Canada, in May 2006. Papers cover advances in system components, experimental testing, uses, and users' experience of automotive and heavy-duty applications. They focus on international coolant development, field testing of additives, recycling, additive compatibility, alternate coolant base technology, extended life oxidation and thermal stability, and new testing methods of cavitation, erosion, and localized corrosion. Contributors are international technical representatives from OEM and engine coolant producers. There is no index.

Recycling of used engine coolants containing ethylene glycol and other glycols would appear to be well established, particularly for reverse osmosis and nanofiltration membrane, electrodialysis, and distillation-based processes. Both literature and recycling facilities indicate success in employing these techniques. However, many recyclers, particularly those employing a single treatment technology, are not capable of producing recycled product meeting original equipment manufacturer (OEM) requirements for coolant, and these typically fall far short of approaching virgin (nonrecycled) coolant quality. In addition, some recycling facilities have produced and marketed product that led to coolant system damage and engine failure, either as a result of not sufficiently removing contaminants or inadequately reformulating with corrosion inhibitors and other additives. The danger of process upsets resulting in inadequate product is particularly high for those facilities that receive feeds with varying contaminant levels and coolants containing a range of corrosion inhibitors and additives (silicates, organic acids, etc.). However, no study to date has focused on a fundamental assessment of the separation characteristics and interactions of the various classes of coolant technologies with the commercially available reverse osmosis, nanofiltration, and electrodialysis ion exchange membranes typically seen in recycling operations. This study presents results of a comprehensive evaluation of the separation characteristics of a wide range of these membranes with a wide range of coolant types. In particular, the study examined production rate characteristics, inhibitor and other additive separation, and contaminant removal for reverse osmosis, nanofiltration, and electrodialysis. Residual inhibitors remaining in the recycled coolant are examined, with guidance provided on how these residuals might affect coolant reformulation and performance.

Over the years, new performance requirements and environmental regulations have driven engine manufacturers to design new engines. The new engine technologies have resulted in different operating conditions in cooling systems. In general, a trend towards higher coolant temperatures is observed, which is expected to have an implication on the coolant stability and corresponding lifetime. In heavy duty applications, this trend is even more pronounced as engines are running longer and under more severe conditions. In this paper, a selection of different current coolant technologies available in the market have been tested to obtain more information on the influence of the coolant additive package on the thermal stability of the most commonly used coolant base fluid, mono ethylene glycol (MEG). For this reason glycol oxidation products have been measured after subjecting the coolants to high temperature oxidative conditions. In addition the physical/chemical stability of the coolants and corrosion protection level of the additive packages have been evaluated.

Annotation Emerging from a November 1991 symposium in Scottsdale, Arizona, 19 papers report on advances in developing, testing, and applying engine cooling fluids for automobiles and heavy duty engines. Among the topics are carboxylic acids as corrosion inhibitors in engine coolant, phosphate-molybdate supplements to heavy duty diesel engines, the toxicity and disposal of engine coolants, and the characterization of used engine coolant by statistical analysis.

EPDM (ethylene-propylene rubber) has been used for more than 25 years as the main elastomer in radiator hoses because it offers a well-balanced price/performance ratio in this field of application. Some years ago the automotive and rubber industry became aware of a problem called electrochemical degradation and cracking. Cooling systems broke down due to a typical cracking failure of some radiator hoses. Different test methods were developed to simulate and solve the problem on laboratory scale. The influence of different variables with respect to the electrochemical degradation process has been investigated, but until recently the influence of the engine coolant was ignored. Using a test method developed by DSM elastomers, the influence of the composition of the engine coolant as well as of the EPDM composition has now been evaluated. This paper gives an overview of test results with different coolant technologies and offers a plausible explanation of the degradation mechanisms as a function of the elastomer composition.

Engine coolant recycling continues to provide solutions to both economic and environmental challenges often faced with the disposal of used engine coolant. General Motors' Service Technology Group (STG), in a continuing effort to validate the general practice of recycling engine coolants, has conducted an in-depth study on the capabilities of recycled coolants. Various recycling processes ranging from complex forms of fractional distillation to simple filtration were evaluated in this study to best represent the current state of coolant recycling technology. This study incorporates both lab and (limited) fleet testing to determine the performance capabilities of the recycled coolants tested. While the results suggest the need for additional studies in this area, they reveal the true capabilities of all types of engine coolant recycling technologies.
