Organic Acid Technology (OAT) coolants are advanced coolant formulations designed to provide superior engine protection and efficiency. These coolants are typically composed of organic acids, which help to prevent corrosion and scale buildup in the cooling system. OAT coolants are known for their long service life and compatibility with a wide range of engine materials, making them a popular choice in the automotive industry.
| Base fluid | Ethylene glycol or propylene glycol |
| pH level | Typically between 7.0 and 8.5 |
| Freezing point | Up to -34°C (-29°F) depending on concentration |
| Boiling point | Up to 129°C (265°F) depending on concentration |
| Service life | Up to 5 years or 150,000 miles |
When selecting an Organic Acid Technology coolant, consider the specific requirements of your vehicle or equipment, including the manufacturer's recommendations for coolant type and specifications. Pay attention to the coolant's freezing and boiling points, as well as its pH level. It's also important to specify the desired service life and any necessary certifications or standards when requesting a quote.

OAT coolants use organic acids for corrosion protection, while conventional coolants often use silicates and phosphates.
Mixing OAT coolants with other types can reduce their effectiveness and is generally not recommended.
Typically, OAT coolants should be changed every 5 years or 150,000 miles, but always refer to the manufacturer's guidelines.
OAT coolants are often considered more environmentally friendly due to their lower toxicity compared to traditional coolants.
OAT coolants can vary in color, commonly found in orange, yellow, or green, but color is not an indicator of performance.
While OAT coolants are compatible with many vehicles, always check the manufacturer's recommendations for your specific model.
