  An overheating Komatsu Construction Equipment engine can stem from several causes. First, check if the coolant supply is insufficient and refill as needed. A slipping fan belt can also cause overheating, so tighten or replace it. Additionally, coolant passages or radiator air passages clogged with dirt or scale can restrict cooling, so clean them. Restrictions in the exhaust pipe or muffler can also cause overheating, so inspect and clear them. Finally, a defective thermostat can lead to overheating, so replace it.
