How to Choose the Right Coolant for Your Car

Choosing the right coolant for your car starts with checking your owner’s manual, as manufacturers specify the exact type and specification designed for your engine. Coolants vary by formulation—such as IAT, OAT, and HOAT—and using the wrong one can lead to corrosion, overheating, or reduced engine life. Consider your vehicle’s make, model, and year, the local climate you drive in, and whether the coolant is premixed or concentrated. It’s also important to match the correct color and standard rather than mixing types, and to choose a high-quality coolant that offers protection against rust, scale, and extreme temperatures for reliable long-term engine performance.
