What are the reasons for the frequent lack of water in the car's auxiliary water tank?

The reasons for the frequent lack of water in the car's auxiliary water tank are as follows: 1. Cooling system: Frequent water shortage indicates a leak in the cooling system or a slight cylinder head gasket failure. 2. Coolant temperature: The coolant temperature may be too high, causing the system to lack water. Leaking coolant can be seen from the front of the engine. 3. Water pump seizure: A seized water pump can damage the timing belt, leading to piston valve contact and other related component failures. 4. Cylinder gasket failure: A blown cylinder gasket (air or water passage) can mix with engine oil or be expelled through the exhaust pipe. 5. Water-cooled air compressor: In a water-cooled air compressor, leakage from the steel gasket can cause seepage.
It's really annoying that the auxiliary water tank in my car keeps running low on water. I've encountered similar situations before, and there are usually several possible reasons. The most common one is a coolant system leak, such as a damaged radiator, loose or aged hose connections, which cause the coolant to slowly leak away. Another reason could be a water pump issue; if the pump is faulty, it can't circulate the liquid properly, leading to a gradual decrease. Alternatively, if the radiator cap doesn't seal well, steam escapes, and the water tank naturally keeps running low. I must mention that if the cylinder head gasket in the engine is burnt, oil mixing into the coolant system can also cause abnormal evaporation of the liquid. It's less noticeable in winter, but in summer when the engine gets hot, the water level drops faster. It's best to check the water tank level before each drive. If you fill it up and notice it dropping again, you should quickly take it to a professional shop for inspection. Otherwise, an overheated engine can cause serious trouble.
