How to Choose the Right Coolant for Your Car

Choosing the right coolant for your car starts with checking your vehicle manufacturer’s recommendations, as different engines require specific coolant types to ensure proper heat transfer and corrosion protection. Coolants vary by formulation—such as IAT, OAT, and HOAT—each designed for different materials like aluminum or cast iron, so using the correct one helps prevent rust, scale buildup, and overheating. Climate also matters: in hot regions, a coolant with strong heat dissipation is essential, while in colder areas, proper antifreeze protection is critical. Always select a high-quality, manufacturer-approved coolant and avoid mixing incompatible types, as this can reduce performance and damage your cooling system over time.
