FIELD INVESTIGATION OF THE EXTENDED USE OF MILITARY ANTIFREEZE UNDER DESERT CONDITIONS
Abstract
The object of the test was to evaluate the use of antifreeze 0-A- 548a, Type 1, under high temperature operating conditions and determine the possibility of extending the use of antifreeze beyond the specified one season. Eight facility vehicles at Yuma Proving Ground were utilized during the test and operated under normal conditions. Four vehicles contained a 50% 0-A-548a, Type 1, antifreeze solution plus 0-1-490a inhibitor. The remaining vehicles contained tap water plus 0-1-490a inhibitor. Results of this test verify results of previous tests which showed that dilution and proper antifreeze addition is difficult to control. Over extended periods a high volume of antifreeze replacement is necessary due to leaks, mechanical failure, evaporation, and overflow. In the field, uncontrolled, improper additions would lead to extensive and expensive cooling system damage. This test reaffirmed that it is not desirable to extend the use of antifreeze beyond the one season specified in TB 750-651. Overheating was not experienced in any of the vehicles under the conditions of this test.
