Common Use Case or Symptoms: Use when the water pump or A/C compressor drive belt is cracking, glazing, squealing, or has broken — a failed belt will result in engine overheating (water pump application) or loss of cab cooling (A/C compressor application) on applicable John Deere skid steer and wheel loader models.
