Coolant is super important for your car. It keeps the engine from getting too hot. This guide helps you pick the right coolant. You want to keep your car running smoothly, right?
Key Features to Look For
You need to know what to look for when buying coolant. Here are the main things:
- Type: Coolant comes in different types. The most common are:
- IAT (Inorganic Acid Technology): This is the old-school type. It often comes in green.
- OAT (Organic Acid Technology): This is a newer type. It often comes in orange or red.

- You must use the right type for your car. Check your car’s manual!
- Protection: Coolant protects your engine from heat, rust, and freezing. It should have:
- Antifreeze: This stops the coolant from freezing in cold weather.
