Many people only think about antifreeze in winter. In fact, antifreeze (coolant) is just as important in summer as it is in winter. It helps the engine operate at its ideal temperature, prevents rust and corrosion, and extends the life of the cooling system.
What does antifreeze do?
- Prevents freezing
- Raises the boiling point
- Protects against corrosion
- Helps protect the water pump and other system components
- Maintains balanced heat transfer
Why is the correct mixture ratio important?
Using only water can increase corrosion, while using only antifreeze may reduce heat transfer efficiency. In most cases, the ideal ratio is around 50% antifreeze / 50% purified water, although this may vary depending on the climate and the product type.
Coolant colors (green, red, blue) are not the only criterion
Color may vary depending on the manufacturer’s formula. What really matters is compatibility: always use the type and specification recommended by the vehicle manufacturer.
When should it be changed?
Over time, coolant loses its protective properties. Follow the replacement intervals recommended by the vehicle manufacturer.
Common signs include: color changes, sediment buildup, constant coolant loss, and temperature fluctuations.
What to watch out for when adding antifreeze
- Mixing compatibility: Combining different types may cause sediment buildup.
- Use purified water: Hard water can leave mineral deposits inside the system.
- Check for leaks: Coolant loss may be caused by a leak.
