Some car owners mainly pay attention to the lubrication system in the maintenance of the engine, and seldom pay attention to the cooling system, but the most common faults of automobile engines, such as piston pulling cylinder, deflagration, cylinder block damage and internal leakage, serious noise, acceleration power drop etc., are caused by abnormal working temperature of automobile engine, excessive pressure, and poor condition of cooling system.
When an engine is in good condition with other systems, whether the cooling system can effectively maintain the normal working temperature of the engine fundamentally determines the working condition of the engine. Pay attention to regularly check the efficiency of the cooling system, avoid the failure of the thermostat, adjust the shutters correctly, eliminate the leakage of the machine, keep the coolant temperature in the normal range, prevent the radiator from overheating, etc.
