1. What is Automotive Coolant?

Besides engine oil, car owners also need to pay attention to other vehicle maintenance products, such as automotive coolant. Automotive coolant is a liquid made from antifreeze agents, anti-evaporative compounds, and highly purified distilled water. By using coolant, your vehicle can maintain stable temperature and optimal operation.

In addition to preventing engine overheating, coolant offers many other benefits such as: minimizing metal component corrosion, preventing scale buildup, preventing corrosion in motors and hydraulic cylinders, etc.

2. What does Automotive Coolant Composition Consist of?

Automotive coolant comprises 5 main components that ensure optimal performance and protect the engine from issues such as freezing or overheating.

• Water: The primary component that enables the cooling solution to transmit heat effectively and prevent freezing at low temperatures.
• Ethylene Glycol or Propylene Glycol: These are antifreeze agents that prevent coolant from freezing at low temperatures. Ethylene Glycol appears in common product lines, while Propylene Glycol is typically used in more environmentally friendly automotive coolants.
• Corrosion inhibitors and anti-yellowing agents: These compounds protect cooling system components from corrosion and scale accumulation, keeping the system running powerfully and durably.
• Anti-foaming agent: Prevents foam formation in the solution, helping maintain good heat transfer capability.
• Dyes and coloring agents: These substances can be added to improve aesthetic appeal and aid in identifying the type of automotive coolant.
