The maintenance methods of truck engine accessories mainly include the following aspects:
Maintenance of engine oil and oil filter: Regular replacement of engine oil and oil filter is the key to keeping the engine running normally. Engine oil will gradually deteriorate during use, affecting the lubrication effect, so it needs to be replaced regularly. The oil filter should also be replaced regularly to prevent impurities from entering the engine and causing wear.
Maintenance of air filter: The air filter is responsible for filtering the air entering the engine to prevent dust and impurities from entering the cylinder. Paper air filters should be cleaned every 50-100 hours of operation, using a soft brush or fan for cleaning; oil bath air filters should be cleaned every 100-200 hours and the lubricating oil should be replaced.
Maintenance of fuel filter: The fuel filter is responsible for filtering impurities in the fuel to prevent impurities from entering the fuel system. The fuel filter should be checked and replaced every 100-200 hours of operation, and the oil-water separator and fuel tank should be checked at the same time to ensure the cleanliness of the fuel system.
Cooling system maintenance: The cooling system is responsible for maintaining the normal operating temperature of the engine. The quality and amount of the coolant should be checked regularly to ensure that the cooling system is unobstructed. The coolant should be replaced once a year to ensure its effectiveness.
Preheating before starting the engine: During a cold start, the surface of the internal parts of the engine is not fully lubricated, and rapid driving will cause wear on the parts. Therefore, after starting, preheating should be performed first, so that the engine coolant reaches the normal operating temperature before gradually increasing the speed.
Check the fastening parts: The engine will be subject to vibration and load changes during operation, and the connection parts such as bolts and nuts are easy to loosen. Regularly check and tighten the engine's fixing bolts, nuts and flywheel housing bolts to ensure a firm connection.
Cleaning sediment and dirt: The engine will produce sludge, oil stains, carbon deposits and other sediments during long-term use, which will affect the smoothness of the lubrication system. Regularly clean the carburetor, diesel pump, diesel filter, air filter and other components to keep them clean.
Check and adjust engine components: Regularly check various engine components, including the radiator, water pump, water pipes, etc., to ensure they are working properly. Adjust and repair loose parts in time to ensure that the engine is in good condition.
