Antifreeze and screenwash
Antifreeze is a coloured liquid needed in your car radiator which reduces the freezing point of the liquids in your car, stopping water from turning to ice when it gets cold which can damage your engine. Car anti freeze also increases the boiling point of water, stopping the coolant from boiling easily when the engine gets hot. Modern antifreeze liquids also contain chemicals to reduce corrosion and extend the life of your engine.
There are different types of antifreeze including universal, red antifreeze and blue antifreeze. Universal antifreeze is formulated to be compatible with most car engines but always check your owner’s manual to see what the manufacturers recommend for your car.
In addition to topping up your coolant fluid with antifreeze in preparation for the winter, you should also add screenwash to your vehicle. Screenwash is used to keep your windscreen clean. At the RAC, we sell a full selection of both antifreeze and screenwash, including concentrated screenwash and ready-made liquids.
You should never use plain water as your screenwash. Modern screenwash solutions are designed to prevent scale build-up in your pipes, and also contain chemicals to break down the kinds of dirt, grime, and even bug parts that get stuck on your windscreen. Plain water and home-made soap solutions are not up to the task. If you use a poor quality screenwash you could end up with smudges and smears on your windscreen. Not only is a streaky windscreen unsightly, it can impair your concentration and make it difficult to see the road clearly when you are driving. A good screenwash will keep your screen clear so that you can concentrate on the most important task, keeping your eyes on the road.
