My unit has a Caterpillar D10 bulldozer has been running nearly 10,000 h, the engine coolant in the engine 2min after the sudden emergence of the coolant temperature rise alarm and the tank of the coolant boiling phenomenon. Accordingly, we carried out a comprehensive inspection of the cooling system and found that the cooling fan speed is particularly low. Because the cooling fan is driven by a hydraulic motor, the hydraulic system is inspected
