What are the reasons for a car radiator running low on water?

The reasons for a radiator running low on water are as follows: 1. Leaking pipe joints or the pipes themselves, requiring pipe replacement or reinforcement of the seal; 2. Cracks in the engine block or a loose/damaged cylinder head gasket, causing water leakage; 3. Damaged seals or sand holes in the oil cooler, leading to water leakage; 4. A loose radiator cap; 5. Leaks in the heater radiator; 6. Leaks in the three-way connector. Methods to determine if there is a water shortage: 1. Check if the exhaust pipe emits white smoke, which indicates water burning, possibly due to cracks in the engine block or a loose/damaged cylinder head gasket; 2. If the engine block has cracks: the radiator will release gas upwards, but it hasn't boiled over; 3. A loose or damaged cylinder head gasket will cause insufficient engine power; 4. Start the engine and use a cloth or tissue to check for leaks at various connections; 5. Fill the radiator with water, leave the cap off, start the engine, and rev to around 2000 RPM to see if bubbles emerge from the radiator, indicating a blown cylinder gasket or likely a deformed cylinder head; 6. For damaged oil cooler seals or sand holes, check the oil for water droplets or emulsification to make a judgment.
I've pondered over the issue of low coolant levels many times. The most common cause is leakage—whether from cracks in the radiator itself or loose connections at the joints, allowing coolant to seep out gradually, leading to a noticeable drop in levels over time. High summer temperatures can also accelerate evaporation, causing significant loss of moisture. Additionally, if there's an issue with the vehicle's engine, such as a damaged cylinder head gasket, coolant may leak into the combustion chamber and burn off, not only reducing the coolant level but also producing white smoke. A faulty water pump can similarly disrupt proper circulation. In my daily driving routine, I make it a habit to regularly pop the hood and check the coolant level to ensure it's adequate, which helps prevent overheating problems. If I notice the level dropping too quickly, I promptly take the car to a repair shop to locate any leaks—neglecting this could lead to bigger troubles. Maintaining the radiator is actually quite simple: just a monthly glance and topping up the coolant as needed. This wisdom comes from decades of driving experience—safety always comes first.
