What Engine Coolant for My Car?

Engine coolant is a vital fluid that helps to keep your car’s engine running smoothly. It circulates through the engine, absorbing heat and transferring it to the radiator, where it is dissipated. Engine coolant also helps to prevent corrosion and lubricate the water pump.

There are two main types of engine coolant: inorganic additive technology (IAT) and organic acid technology (OAT). IAT coolants are typically green or yellow, while OAT coolants are typically red or orange. IAT coolants contain silicates and phosphates, which can help to protect metal components from corrosion. However, these additives can also break down over time, forming deposits that can clog the cooling system.

OAT coolants do not contain silicates or phosphates. Instead, they use organic acids to protect metal components from corrosion. Organic acids are less likely to form deposits than silicates and phosphates, so OAT coolants can last longer than IAT coolants.

Which type of engine coolant is right for my car?

The type of engine coolant that is right for your car depends on the make, model, and year of your vehicle. You can find the recommended type of engine coolant in your owner’s manual.

If you are not sure which type of engine coolant to use, you can always consult with a qualified mechanic. They can help you choose the right coolant for your car and make sure that it is properly installed.

How often should I change my engine coolant?

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

It is important to check your coolant level regularly and to have it changed according to the manufacturer’s recommendations. This will help to keep your engine running smoothly and prevent costly repairs.

Here are some tips for choosing and using engine coolant:

Always use the type of engine coolant that is recommended by your car’s manufacturer.
Do not mix different types of engine coolant.
Check your coolant level regularly and add coolant as needed.
Have your coolant changed according to the manufacturer’s recommendations.
