The effect of aluminum automotive cooling system components on antifreeze compounds and other cooling system metals was investigated. Bench corrosion tests were used to screen antifreeze compounds and inhibitors for use in systems containing aluminum. Suitable combinations were then placed in simulated vehicle circulation units containing aluminum in conjunction with other metals. Preliminary results indicate that the presence of aluminum in military automotive cooling systems would present no immediate problem when employing antifreeze meeting Federal Specification O-A-548a with additional inhibitor meeting Federal Specification O-1-490.
