Answer six questions about what you see in the machine. You will get the most likely causes in the cooling system and what to check first.

About this diagnosis

  • It is guidance based on the most common causes of overheating in heavy equipment and on findings from the MESABI® workshop.
  • It does not replace an inspection: confirm with temperature readings, a pressure test and the machine's manual.
  • If the temperature warning comes on, stop the machine safely and let it cool before opening the cap.
