Can You Put Any Engine Coolant in Any Car?

When it comes to maintaining your car, there are a lot of different fluids and chemicals that you need to keep an eye on. One of the most important is engine coolant, which helps to keep your engine running at the proper temperature. But can you just put any engine coolant in any car?

The Different Types of Engine Coolants

There are three main types of engine coolants: inorganic additive technology (IAT), organic acid technology (OAT), and hybrid organic acid technology (HOAT). IAT coolants are the oldest type and are made with silicates and phosphates. OAT coolants are newer and are made with organic acids. HOAT coolants are a hybrid of IAT and OAT coolants and contain both silicates and organic acids.

IAT Coolants

IAT coolants are the most affordable type of coolant and are compatible with most older vehicles. However, they do not last as long as OAT or HOAT coolants and can cause corrosion in some engines. IAT coolants are typically colored green or blue.

OAT Coolants

OAT coolants are more expensive than IAT coolants, but they last longer and provide better protection against corrosion. OAT coolants are typically colored orange or red.

HOAT Coolants

HOAT coolants are a hybrid of IAT and OAT coolants and offer the best of both worlds. They are more affordable than OAT coolants, but they provide better protection against corrosion. HOAT coolants are typically colored yellow or pink.

Which Type of Engine Coolant Do I Need?

The type of engine coolant you need depends on the make and model of your car. You can find the recommended type of coolant in your owner’s manual. If you are not sure what type of coolant to use, you can always consult with a mechanic.

Can You Mix Different Types of Engine Coolant?

No, you should never mix different types of engine coolant. Mixing different types of coolant can cause chemical reactions that can damage your engine.

How Often Should I Change My Engine Coolant?

The frequency with which you should change your engine coolant depends on the type of coolant you are using. IAT coolants should be changed every 2 years or 30,000 miles, while OAT and HOAT coolants can last up to 5 years or 100,000 miles.

Conclusion

Engine coolant is an important part of your car’s cooling system. It helps to keep your engine running at the proper temperature and protects it from corrosion. It is important to use the correct type of coolant for your car and to change it regularly.
