On 6.2L diesel equipped "C/K" models, the upper radiator hose has a shield to protect it from the A/C belt. In July of 1983, the part
number was changed to 14071983 with a shield length of 57.2 mm (2.25 inches). The old clamp part number 14045655 had a shield
length of only 38.1 mm (1.50 inches).
Should you encounter vehicles where the belt is contacting the hose, make sure the new clamp is installed and adjusted properly.
