Antifreeze is a concentrated glycol-based liquid that must be diluted with water before use, when it becomes a coolant. Its main role is to lower the freezing point of the liquid and thus prevent engine damage, but also to increase the boiling point of water, prevent the formation of scale, corrosion, deposition and foaming, and lubricate engine parts.
There are two main groups of antifreeze, mono ethylene glycol-based and mono propylene glycol-based. We recommend you to refer to the owner’s manual to find out which type your engine needs. Each antifreeze contains special additives to prevent corrosion of the metal surfaces in the cooling system. Do not mix different antifreezes, which will adversely impact additive performance.
