Do Cars Need Water? How Often Should It Be Added?

[LeDonovan]

Cars do not require water; they need to use specialized coolant. Relevant information is as follows: Engine: The engines used in cars are all water-cooled engines, which rely on coolant continuously circulating within the engine to dissipate heat. The coolant has two circulation paths within the engine: one is the major cycle, and the other is the minor cycle. When the engine is just started, the coolant undergoes the minor cycle, during which it does not pass through the radiator to dissipate heat, helping the engine to warm up quickly. After the engine runs for a while and reaches normal operating temperature, the coolant switches to the major cycle, passing through the radiator to dissipate heat, thereby maintaining the engine within the normal operating temperature range. Coolant: The coolant needs to be replaced periodically. If not replaced for a long time, the coolant's freezing point may rise, and its boiling point may drop, affecting the engine's normal operation. Therefore, it is essential to regularly replace the coolant during routine car use. When replacing the coolant, ensure that the old coolant in the cooling system is completely drained before adding new coolant.
