[LeKiara]

If there is a coolant leak, the first step is to identify the source of the leak. Start from the coolant reservoir and follow the coolant circulation lines to check for leaks at connection points, water pump, or radiator. Possible causes include loose hose clamps, aged hoses, rusted radiator, or damage from collision accidents. Additional relevant information is as follows: Introduction: Coolant is a liquid containing special additives, primarily used in liquid-cooled engine cooling systems. It prevents freezing in winter, boiling in summer, scaling, and corrosion year-round, ensuring the engine operates within the normal temperature range. Application: Coolant is generally used in automobiles, diesel locomotives, tractors, ships, engines, radiators, and various mechanical equipment, serving as a cooling liquid in diesel and gasoline engine cooling systems.
