In the automotive industry, engine cooling systems play a crucial role in maintaining the optimal operating temperature of the engine. Two of the most commonly used coolants in modern vehicles are G12 and G13. Both coolants are designed to provide efficient heat transfer and protect the engine from corrosion and overheating. However, when it comes to using G12 coolant instead of G13, several factors come into play.
The Chemistry Behind G12 and G13 Coolants
G12 and G13 coolants are both organic acid technology (OAT) coolants, which means they use organic acids to neutralize the corrosive effects of the coolant on metal surfaces. However, the chemical composition of G12 and G13 coolants differs in terms of their acid levels and the type of additives used.
- G12 coolants typically contain a higher concentration of organic acids, which provides better corrosion protection for aluminum components.
- G13 coolants, on the other hand, have a lower acid level and are designed to be more compatible with a wider range of engine materials, including steel and cast iron.
Key Differences Between G12 and G13 Coolants
The key differences between G12 and G13 coolants are:
- Acid level: G12 coolants have a higher acid level than G13 coolants.

Understanding the Difference Between G12 and G13 Coolants
Background Information on Coolant Types
Coolants are an essential component in various industries, including automotive, aerospace, and industrial processes. The primary function of a coolant is to regulate the temperature of a system by absorbing heat from the surrounding components. In the automotive industry, coolants are used to prevent overheating in engines, transmissions, and other mechanical components. The type of coolant used depends on the specific application, temperature range, and chemical composition.
In recent years, the automotive industry has shifted towards the use of OAT (Organic Acid Technology) coolants, which are designed to provide better corrosion protection and longer service life. Two popular types of OAT coolants are G12 and G13. While both coolants share similar properties, they have distinct differences in their chemical composition, performance, and application.
Key Differences Between G12 and G13 Coolants
| | G12 Coolant | G13 Coolant |
| — | — | — |
| Chemical Composition | Ethylene glycol-based with additives | Propylene glycol-based with additives |
| Corrosion Protection | Better protection against corrosion in aluminum components | Excellent protection against corrosion in aluminum and copper components |
| Service Life | Longer service life (up to 5 years) | Longer service life (up to 6 years) |
| Temperature Range | Suitable for temperatures up to 105°C (221°F) | Suitable for temperatures up to 115°C (239°F) |
As shown in the table above, G12 and G13 coolants have distinct differences in their chemical composition, corrosion protection, service life, and temperature range. G12 coolants are based on ethylene glycol, while G13 coolants are based on propylene glycol. Propylene glycol is a more environmentally friendly and non-toxic alternative to ethylene glycol.
Can I Use G12 Coolant Instead of G13?
While G12 and G13 coolants share similar properties, they are not interchangeable. G12 coolants are designed to provide better corrosion protection in aluminum components, whereas G13 coolants offer excellent protection in both aluminum and copper components. If you are using a G12 coolant in an application that requires G13 coolant, you may experience reduced corrosion protection and a shorter service life.
However, if you are looking to upgrade from G12 to G13 coolant, you can consider the following factors:
- Temperature Range: If your application operates at temperatures above 105°C (221°F), G13 coolant may be a better option due to its wider temperature range.
- Corrosion Protection: If your application requires excellent corrosion protection in both aluminum and copper components, G13 coolant may be a better choice.
- Service Life: If you want to extend the service life of your coolant, G13 coolant may be a better option due to its longer service life.
