As well as preventing water from freezing up, antifreeze raises the boiling point of engine coolant to prevent overheating, protects your engine from corrosion, aids heat transfer, and prevents scale from building up internally. Antifreeze is either sold in concentrated form, or ready mixed with water. The ready mixed version is commonly referred to as engine coolant and can normally be used straightaway for top ups and replacements. However the concentrated forms needs to be diluted with water, usually at a level of around 50% antifreeze and 50% water. Always check the instructions for the right ratio to use. It is also recommended that you change your engine oil at least once every 12000 miles, or once a year especially if you drive in hot weather.
General Tips on Antifreeze
Coolant is usually red, green, blue or yellow. If it looks colourless, looks rusty, or has things floating around in, flush your cooling system, and add new coolant. If the coolant has a sludgy, oil surface, immediately take the vehicle to your mechanic to check for internal head gasket leakage. The service facility should have special equipment for performing this check, only check the coolant level when the engine is cold - it should be the maximum and minimum marks.
Check regularly and look out for wet or white staining on coolant hoses too, refer to the handbook to make sure you use the correct type of antifreeze and follow the correct procedure
Don’t remove the coolant filler cap unless the engine is cold - the system is pressurized and you risk a face full of scalding hot water if you release it with the engine hot
If the level drops in modern cars m the sealed cooling system must be escaping from somewhere, a possible leak, check the floor for possible spillages, and ask a garage/expert for advice
