Winterization of Vehicles To -50F

Discussion in this paper is centered on general problems of subarctic operation, results of the 1968-1969 winter testing at Ft. Churchill, Manitoba, Canada, and the testing planned for the 1969-1970 season at Ft. Churchill. Significant findings from the 1968-969 testing indicate the vital importance of care in preparation of vehicles for the arctic, the need for greater simplicity and reliability in design of winterization systems, and the inadequacy of currently used elastomeric components (hoses, o-rings, etc.).
