Support System (Saweria) click the following link: https://saweria.co/themechaniche One characteristic of diesel engines is that they tend to take a long time to warm up. This is because diesel engines have higher thermal efficiency than other engines. Heat energy in diesel engines tends to be transferred more efficiently, so less heat is wasted to the radiator. Diesel engines are also equipped with a conventional radiator fan that runs when the engine is running, even when the engine is still cold. In general, a normal diesel engine takes more than 30 minutes to reach optimal temperature. However, you should be suspicious if your diesel engine overheats more quickly. It could be due to one of the five causes of a diesel engine overheating listed below! 1. Radiator Water Leaks The first cause of a diesel engine overheating easily is a radiator leak. Radiator water essentially acts as a conductor of heat, allowing the engine to cool and distribute the heat. The circulating coolant within the engine ensures that the heat is distributed evenly. When the coolant volume is reduced due to leaks, whether caused by loose hose connections, broken radiator hoses, or a leaking radiator, the engine's heat cannot be distributed evenly. Even when the engine is just running, the hotter parts are actually at the top of the engine. 2. Blocked Water Pipes in the Engine (Water Jacket) Dirt or scale in the rotating coolant pipes inside the engine can cause blockages, which can cause a diesel engine to overheat easily. The dirt or scale originates from the edges of the water jacket, which are scratched by heat. This condition prevents the coolant from working smoothly and causes the engine to overheat more quickly. 3. Damaged Coolant Temperature Sensor Generally, the engine coolant temperature sensor, or coolant temperature sensor, is found in common rail diesel engines and is responsible for monitoring the coolant temperature. The data displayed by the coolant temperature sensor is used to indicate when the cooling fan will turn on and to indicate the amount of diesel fuel injected. Damage to the coolant temperature sensor can provide incorrect information. For example, the engine may be hot, but the sensor still indicates a cold temperature. This condition causes the engine's ECU to activate a system to quickly warm up the engine. 4. Thermostat Won't Open The thermostat is a valve that opens and closes the coolant channel from the engine to the radiator. The thermostat's role is to help the engine warm up quickly. When the engine is still cold, the thermostat closes, and when the coolant temperature in the engine begins to feel hot, the thermostat automatically opens. When the thermostat fails to open, the coolant typically circulates within the engine, preventing heat from escaping to the radiator. This slows down the engine's warm-up process. 5. Water Pump Not Turning Finally, a diesel engine that overheats easily is caused by a malfunctioning water pump. The function of the water pump is to ensure proper coolant circulation. If the water pump is not functioning properly, the coolant will usually not circulate, resulting in the engine's heat not being distributed evenly. Malfunctioning or damaged radiator fan/fan belt The radiator fan is located behind the radiator and functions to facilitate airflow from the front of the radiator across the radiator fins, ensuring smooth and optimal heat dissipation from the radiator to the outside air. Stuck water pump The radiator pump circulates coolant through the water layer, absorbing heat from combustion, which is then channeled to the radiator for heat dissipation. Damaged radiator cap The radiator cap part of the radiator plays a very important role. If the radiator cap has a problem, the air pressure in the radiator will decrease little by little due to leaking air. The fan belt broke Inside the generator there is a fan belt installed to connect the engine rotation to the radiator fan itself Clogged radiator fins The wider the radiator fins, the easier the process of releasing heat from the radiator to the outside air that flows between the radiator tubes. For example, if the radiator fins are blocked by small objects, this can cause a tendency for the engine to overheat. #diesel #overheating #excavator
