Why Choosing the Right Antifreeze and Coolant Matters for Your Vehicle
There are three main types of antifreeze and coolant:
- Inorganic Acid Technology (IAT): IAT coolant is the oldest and most common type of coolant. It is typically green in color and contains silicates and phosphates, which help to protect the engine from corrosion. IAT coolant is relatively inexpensive and easy to find, but it needs to be replaced more often than other types of coolant, usually every 30,000 miles.
- Organic Acid Technology (OAT): OAT coolant is a newer type of coolant that is becoming more popular. It is typically orange, yellow, or red in color and does not contain silicates or phosphates. OAT coolant is more expensive than IAT coolant, but it lasts longer, typically 150,000 miles or more.
- Hybrid Organic Acid Technology (HOAT): HOAT coolant is a hybrid of IAT and OAT coolant. It typically contains a small amount of silicates and phosphates, but it also contains organic acids. HOAT coolant is typically orange or yellow in color and lasts for about 150,000 miles.
Selecting the appropriate coolant for your vehicle is crucial in maintaining optimal engine performance and longevity. Your owner’s manual provides valuable insights into the specific type of coolant recommended by the manufacturer for your particular make and model. However, should any uncertainty arise regarding the suitable coolant for your vehicle, it is highly advisable to seek guidance from a certified mechanic or an automotive professional. They possess the expertise to not only identify the correct coolant but also ensure that it aligns with your car’s specific requirements, including its year, make, and engine type.
Making the right choice for your vehicle’s cooling system not only enhances its efficiency but also contributes to the overall well-being of your car’s engine.
Here is a table that summarizes the key differences between the three types of antifreeze and coolant:
Type | Color | Additives | Change interval |
---|---|---|---|
IAT | Green | Silicates and phosphates | 30,000 miles |
OAT | Orange, yellow, or red | None | 150,000 miles or more |
HOAT | Orange or yellow | Small amount of silicates and phosphates | 150,000 miles |
It is important to note that you should never mix different types of coolant. This can cause the coolant to lose its effectiveness and can even damage your engine.
