Engine Cooling System Survey of Military Antifreeze MIL-A-46153 Field Performance
Abstract
The purpose of this survey was to determine whether or not the current formula for Military Specification antifreeze. MIL-A-46153, requires improvement. It consisted of a questionnaire (see Appendix A), with 25 questions pertaining to cooling system-related overhauls and cooling system component replacement frequencies. The number and types of vehicles varied significantly among the 87 motorpools. Responses to question 2 revealed that small cooling system components are replaced more often, per year, than other components. Components such as thermostats, hoses, radiator caps, radiator drain plugs, and engine block drain plugs were among the smaller items that appear to be more susceptible to degradation as compared to larger components such as water pumps, radiators, and engine blocks. Radiators and water pumps were also tied for the second most frequently replaced component per year, comprising 22% and 23% of the total, respectively. Heater cores represented 13% of the components replaced and engine blocks only 3%.
