Antifreeze at Halfords
Antifreeze is pretty much essential to keeping your car running smoothly during those chilly winter months.
As the name suggests, antifreeze lowers the freezing point of the water in your car's engine cooling system, preventing the water from freezing when winter rolls around. If it's allowed to freeze, it can damage parts of your engine which you definitly dont want!
It's also used to increase the boiling point of engine coolant to prevent it from overheating. This protects your engine from corrosion and aids 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.
