one ?? Check the coolant: First, check the coolant level in the cooling system to ensure it is within the standard range. If the coolant is insufficient, it is necessary to add an appropriate amount of coolant in a timely manner. At the same time, check whether the coolant is expired or contaminated, and replace it if necessary. In addition, carefully investigate whether there are any leakage points in the cooling system. Common leakage locations include water pipes, water tanks, water pumps, etc.
two ?? Cleaning the water tank and radiator: The cooling fins of the water tank and radiator may be blocked by dust and debris, affecting the heat dissipation effect. You can use a low-pressure water gun to carefully rinse the front, back, and surrounding areas of the radiator fins to remove blockages, but be careful not to deform the fins due to excessive water pressure. If the water tank or radiator is damaged, it should be replaced in a timely manner.
three ?? Check the thermostat: A faulty thermostat can affect the circulation of coolant. Water boiling and other methods can be used to check whether the thermostat can be opened normally. If the main valve of the thermostat cannot be fully opened, stuck or poorly sealed, causing leakage of the expansion body and hindering the circulation of cooling water, the thermostat should be replaced in a timely manner.
four ?? Check the silicone oil fan: Ensure that the silicone oil fan operates normally without any signs of breakage or fatigue failure. For fans connected by belts, it is necessary to check the tightness of the belts and adjust or replace them if necessary to ensure that the fan speed is normal and can effectively increase the heat dissipation effect.
five ?? Check the engine oil and oil filter: Check the oil level to ensure it meets the requirements and avoid excessive or insufficient oil. Too little engine oil can affect lubrication and heat dissipation, while too much can increase engine operating resistance. At the same time, regularly replace the oil filter element to prevent it from clogging and affecting the filtering effect of the oil.
six ?? Other related component inspection: Check the engine oil level, add as required, and prevent excessive or insufficient oil. Check the drive belt of the fan, replace it promptly if there is any breakage or fatigue failure, and adjust its tightness to an appropriate level. Check the cooling system components such as water temperature sensors and water pumps to ensure that they are working properly and can effectively maintain the operation of the cooling system.
seven ?? Troubleshooting workload issues: If the loader frequently operates under heavy loads, especially during heavy climbing, it can easily lead to excessively high water temperatures. Attention should be paid to avoiding long-term high load operation of the engine to prevent affecting its service life.
? It should be noted that the specific maintenance methods may vary depending on the model, brand, and actual situation of the loader. During the maintenance process, a detailed inspection and analysis should be conducted based on the specific situation of the loader to accurately identify the root cause of the high temperature problem and take effective solutions. If the maintenance is uncertain or the problem is complex, it is recommended to consult the manufacturer of the loader or professional maintenance service personnel.
