Some coolants are sold as a ready-to-use solution with a 50:50 mix of water and coolant, whereas others are a coolant concentrate that is intended to be diluted by the user. Coolants with organic additives are referred to as ‘global’ coolants or ‘HOAT’ (hybrid organic acid technology) whereas inorganic additive coolants are referred to as ‘IAT’ (inorganic acid technology). Many coolants contain organic versions of these additives, or a combination of inorganic and organic additives. Other additives in antifreeze include corrosion inhibitors and lubricants. This circulation process continues as necessary, while your car’s thermostat works to regulate the temperature of the coolant and the engine.Įngine coolants contain antifreeze so they do not become frozen when the outside temperature drops below zero. As the liquid flows through the intercooler, it’s cooled by the air as your vehicle travels down the road. Once the coolant becomes too hot to effectively cool the engine, it’s drawn back out through a separate hose before passing through the intercooler. The liquid is circulated into the engine through a hose into gaps or ‘passages’ in the engine block. Engine coolant plays a vital part in keeping your engine running in top shape (and just running period) and prolonging the life of the engine and its components.Ĭoolant is a water-based liquid that works to draw heat from your engine.
