The type of engine coolant your car needs depends on the make, model, and year of your vehicle. Generally, there are three main types of coolant: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT). IAT is typically used in older vehicles and is usually green, OAT is used in many newer vehicles and comes in colors like orange, red, and dark green, while HOAT is a hybrid of the two and is often yellow or turquoise. It’s crucial to refer to your car’s owner’s manual to find the manufacturer-recommended coolant type, as using the wrong type can lead to corrosion, overheating, and engine damage. Always ensure that the coolant you choose is compatible with your car’s specific engine and cooling system.
