As the name suggests, Antifreeze is used to stop the fluids in your engine coolant, windscreen washer and brakes from freezing. It’s best to have this checked before the freezing temperatures arrive to ensure that the effectiveness is as expected, if not this is easily replaceable to ensure you aren’t caught out. Naturally this will also make you check the levels of your fluids, to ensure they are as they should be. It’s always advisable to carry a bottle of screen wash in your car, just in case you ever run out mid-journey!
