What are the reasons for the reduction of car coolant?

The reasons for the reduction of car coolant are: 1. Leakage in the engine cooling system, causing the coolant to leak out; 2. Thermal expansion and contraction. It is normal for the coolant to slowly decrease, but if the coolant level changes significantly within a certain period, attention should be paid. Coolant is a type of antifreeze coolant that prevents freezing and cracking of the radiator and engine cylinder block during cold seasons. Precautions for car coolant include: 1. Some engines are filled with long-life coolant, and after working for a period of time, the radiator cap should be opened for inspection. When dirt, rust, or sediment appears in the radiator, the coolant should be replaced promptly; 2. Do not come into contact with antifreeze, as both the antifreeze and its additives are toxic substances. Avoid contact and store them in a safe place.
I have considerable driving experience, and there are several common situations where coolant levels decrease. First is aging and cracked pipes leaking, especially after long drives in high temperatures where rubber hoses can deform and crack at the joints. Second could be a worn-out water pump seal causing slow leaks—you might find a small puddle under the car when parked in the garage. Third, a damaged engine head gasket may allow coolant to seep into the combustion chamber, where it evaporates; symptoms include white smoke at startup and sluggish acceleration. Fourth, radiator corrosion can lead to tiny leaks, with slightly increased evaporation in summer heat. Regularly checking fluid levels is essential. If you notice rapid loss, use a pressure tester to locate leaks—otherwise, engine overheating could cause catastrophic damage, leading to major trouble.
