Antifreeze is a very important engine fluid for vehicles

1. The role of antifreeze in automotive engines

Antifreeze is a colored liquid used to regulate engine temperature. With ethylene glycol as its main component, antifreeze can lower the freezing point and raise the boiling point of water, thereby preventing water in the radiator from freezing in extremely cold temperatures or evaporating when temperatures rise significantly.

Along with fuel and automotive lubricants, antifreeze is an essential element for engines to operate smoothly and stably. Besides its ability to regulate engine temperature, antifreeze also lubricates the components of the cooling system and protects metal parts from corrosion.

2. Are antifreeze and coolant the same?

The terms "antifreeze" and "coolant" are often used interchangeably. Many customers of Huynh Chau automotive lubricant distributor mistakenly believe these two liquids are the same. However, this is actually not accurate.

Antifreeze is only one component of engine coolant. More specifically, coolant is a mixture consisting of antifreeze and water. The ratio between components can vary depending on the type of coolant. However, most products currently available on the market are mixed with a 50/50 ratio of antifreeze to water.

3. Do you need to replace antifreeze frequently?

Similar to automotive lubricants, antifreeze deteriorates over time and becomes acidified. This can lead to corrosion and damage to cooling system components such as the radiator, water pump, hoses
