Parts Glossary
Radiator: A heat exchanger used to cool the engine's coolant. It is typically located at the front of the vehicle. Example: Komatsu PC200-8 Radiator.
Water Tank (Coolant Reservoir): A container that holds excess coolant and allows for expansion as the engine heats up. Example: Komatsu PC210-8 Water Tank.
Turbocharger: A device that forces extra air into the engine's cylinders to increase power and efficiency. It is driven by exhaust gases. Example: Cummins QSK60 Turbocharger.
Hydraulic Pump: A component that generates flow in a hydraulic system, providing the power for hydraulic cylinders and motors. Example: Caterpillar 320D Hydraulic Pump.
Starter Motor: An electric motor that cranks the engine to start it. Example: Kubota D1105-T-E3B-KEA-1 Starter Motor.
Fuel Injector: A device that delivers precisely metered fuel into the engine's combustion chamber. Example: Cummins ISF2.8 Fuel Injector 5258744.
Solenoid Valve: An electromechanically operated valve used to control the flow of hydraulic fluid or air. Example: Rexroth Solenoid Valve R901155051.
Engine Sensor: A device that monitors various engine parameters (e.g., temperature, pressure) and sends data to the control unit. Example: Volvo EC240 Camshaft Sensor.
Oil Seal: A seal used to prevent lubricant leakage and keep contaminants out of rotating shafts. Example: Perkins 1106 Front Oil Seal.
Control Valve: A valve used to control the direction, pressure, or flow rate of hydraulic fluid. Example: Yuken Directional Control Valve DSG-01-3C2-D24-N1-50.
Common Fault and Solution
Equipment: Komatsu PC200-8 Excavator
Fault: Engine overheating, especially under load.
Cause: A common cause is a clogged radiator or a failing water pump, reducing coolant circulation. Low coolant level or a faulty thermostat can also be culprits.
Solution:
Visually inspect the radiator fins for debris (dirt, leaves) and clean them carefully with compressed air or water.
Check the coolant level in the reservoir and top up with the manufacturer-recommended coolant mixture if necessary.
Inspect the water pump for leaks or unusual noises. Replace if faulty.
Test the thermostat for proper operation. Replace if it fails to open at the specified temperature.
If the problem persists after these steps, the radiator itself might be internally blocked and may need flushing or replacement. Using a genuine Growshine Komatsu radiator water tank (20Y-03-42452/205-03-31110) ensures optimal cooling performance.
Regular Maintenance Tip: Perform coolant system flushes according to the Komatsu maintenance schedule to prevent sediment buildup.
Radiator and Cooling System Knowledge
The radiator is a vital part of the engine's cooling system. Its primary function is to dissipate heat from the coolant that has circulated through the engine block. A typical radiator consists of a core of tubes and fins that increase the surface area for heat exchange. A water pump circulates the coolant, while a fan draws air through the radiator to aid cooling. The water tank (or coolant reservoir) provides a buffer for coolant expansion and contraction with temperature changes. Using high-quality components, like those from Growshine International, is essential for preventing engine overheating, which can lead to severe damage like a cracked cylinder head or warped components. Regular inspection of hoses, clamps, and coolant levels is crucial for the longevity of your Komatsu excavator's cooling system.
