Do Sedans Need to Add Water?

[ColtonFitz]

Cars do not need to add water. What is commonly referred to as adding water actually means adding coolant. The engines used in cars are water-cooled engines, which rely on the continuous circulation of coolant within the engine to dissipate heat. Without coolant, the engine would overheat, which could severely damage the vehicle's performance in serious cases. Below are some precautions for using coolant: Regular Replacement: Most coolants have a validity period of two years. When adding coolant, ensure the product is within its validity period. It must be replaced regularly, typically every two years or every 40,000 kilometers driven. Taxis should replace it more frequently. Coolant Selection Principles: Choose the freezing point of the coolant based on the environmental temperature conditions. The freezing point is one of the most important indicators of coolant, determining whether it can prevent freezing. Select coolant according to the specific requirements of the vehicle. Generally, imported vehicles, domestically produced imported models, and mid-to-high-end vehicles should use permanent coolant, while ordinary vehicles can use direct-use coolant, and softened water can be used in summer.
