1. Fan (engine and engine cooling)

   NHTSA 77V173000 Reported October 12, 1977 48,000 vehicles potentially affected MACK TRUCKS, INCORPORATED

   The flex blade fans on the involved vehicles may develop cracks in the laminated stiffener as a result of fatigue during operation. If such a condition exists and the cracks go undetected, continued operation could cause pieces of the stiffener to break off.

   Remedy: Dealer will replace the original fan with a steel fixed blade fan, free of charge.
