Understanding Car Antifreeze Coolant

Car antifreeze coolant plays a crucial role in regulating your engine temperature. By preventing the engine from overheating and freezing, it ensures that your vehicle runs smoothly under various weather conditions. This fluid is a mixture of water and chemicals, primarily ethylene glycol or propylene glycol, which lower the freezing point and raise the boiling point of the fluid.

When selecting the appropriate antifreeze coolant, it's important to understand the types available. Here are the most common types:

  • Inorganic Acid Technology (IAT) Coolant

    • Typically green in color.
