What are the reasons for the decrease in coolant level?

[DiHope]

There are several reasons for the decrease in engine coolant level in a car: 1. Poorly designed cooling system; 2. Rapid consumption due to poor circulation; 3. Leakage, with visible traces of seepage; 4. Coolant entering the cylinder and being burned or entering the oil pan. Below is additional information about coolant: 1. The cooling system is an important device that helps dissipate heat from the car engine. However, due to the use of antifreeze, it is particularly important to strengthen the inspection and maintenance of the cooling system after driving for a certain period of time. 2. Have a professional mechanic conduct an inspection. When adding coolant, ensure the engine has cooled down before doing so. During the process, start the engine and appropriately press the accelerator to expel air from the system. Add the coolant slowly, and if necessary, follow the instructions in the manual to vent the cooling system.
