K-Seal HD is a ceramic and copper formula that mixes with all types of anti-freeze to make permanent repairs to cooling systems on all larger capacity engines. K-Seal stops leaks in the engine’s block, head, radiator, heater matrix, freeze plugs and the head gasket by pouring the contents into the engine coolant. One 16 ounce bottle treats cooling systems of up to 50 quarts capacity.
Affected tractors are equipped with an automated Eaton UltraShift Plus or Eaton Advantage Transmission with right hand stalk shifter. In the affected trucks, the display on the instrument panel can indicate “N” when the shifter is set into “D” or “R,” causing the truck not to move.
