Antifreeze is essential to keeping your car running smoothly during the winter months. Antifreeze lowers the freezing point of the water in your car's engine cooling system, preventing the water from freezing when the mercury drops.

If the water is allowed to freeze, it could damage your engine once it's heated up, resulting in costly repairs.

Antifreeze is also used to increase the boiling point of engine coolant to prevent it from overheating, protecting your engine from corrosion and aiding heat transfer.

Our wide choice of antifreeze comes in two forms: ready mixed (often known as coolant) and concentrate, so it's up to you to pick which you prefer, or use one of or antifreeze testers.
