Antifreeze is an important fluid for your car, serving a variety of different purposes in modern vehicles. Not only does it reduce the freezing point of your car liquids, as the name might suggest, and stop liquid from turning to ice in freezing temperatures, but it also serves to increase the boiling point of liquids in your car that are at risk from getting too hot, such as your engine coolant. For this reason it is a good idea to top up your antifreeze in preparation for driving in winter, but it is also important that you keep your antifreeze topped up all year round. Car antifreeze can also extend the life of your engine and reduce corrosion thanks to its formulation of chemicals. Like any liquid in your vehicle, your antifreeze is not ever-lasting, so keep an eye on fluid levels and top up when necessary with the RAC antifreeze range.
