Engine coolant is designed to remove excess heat from your vehicle’s engine and cooling system while also lubricating components for improved efficiency and longer service life.

Coolants typically consist of water mixed with either ethylene glycol or propylene glycol to control temperature. Furthermore, corrosion inhibitors and dyes may be included.

Function

Engine coolant flows through your car’s radiator to help regulate temperature fluctuations, helping prevent its engine from overheating in hot weather or freezing up in cold weather. It prevents overheating when temperatures soar while helping prevent freezing when temperatures plummet.

Internal combustion engines produce significant heat when burning fuel to create energy for propulsion of your car forward. While some of this heat dissipates through exhaust, some is absorbed by engine block and heads where it could potentially cause damage.

The engine coolant system uses the natural cooling properties of ethylene or propylene glycol and distilled water to protect your car’s engine. It contains corrosion inhibitors to minimize metal-to-metal contact while also providing corrosion prevention measures, corrosion inhibitors and lubricating certain parts of its cooling system such as water pumps.

There are three engine coolants commonly used in cars: IAT (Inorganic Acid Technology), OAT (Organic Acid Technology), and Silicated HOAT (Hybrid Organic Acid Technology) or long life coolants. While IAT coolant requires frequent replacement to remain effective, OAT long life green coolants have been approved by several carmakers including GM Dex-cool, Chrysler and some Fords; Silicated HOAT long life coolant is free from nitrites, phosphates borates or amines making this an excellent long life green coolant choice which Mercedes Benz, BMW/Mini, VW/Audi and Porsche all use this type of long life coolant coolant type as part of their coolant portfolios.

Composition

Coolants come in various shades of green, orange or red; however, color should not dictate which antifreeze type should be used in your car – instead rely on its owner manual and manufacturer guidelines as your source for guidance.

Chemical components of coolants are essential in providing your engine and its components with protection from overheating. Most coolant liquid is composed of ethylene glycol – this colorless substance prevents engine from overheating in winter weather as well as cooling overheat in hot weather.

Modern antifreeze mixtures are designed for specific uses. Manufacturer-specific coolants like Subaru Blue and VW/Audi G12 are specifically tailored to match the requirements of one vehicle’s engine, providing superior corrosion protection, thermal stability, and seal degradation prevention. Other coolant types, like HOAT/ELC hybrids (Hoat Overcoat/Indirect Antifreeze Combi Acid Treatment/Extended Life Carboxoxylate), combine elements from OAT and IAT formulas in order to offer long service life protection as well as advanced corrosion protection; Valvoline offers HD Nitrite-Free products which specifically targets automotive metals while meeting specifications set by major automakers.

Benefits

Engine coolant is an indispensable fluid that maintains an engine at an ideal operating temperature. Without it, overheating would damage its components; its removal removes heat from radiators and stops engine water from boiling when overheated in summer months; additionally it protects parts against corrosion damage as well as providing immunity from rusting.

Engine coolant contains ethylene glycol as its main ingredient, providing resistance against freezing in cold temperatures and boiling in hotter ones. Other components make the coolant effective as a heat transfer agent.

Manufacturer-specific coolants are tailored to meet the specifications of your engine, providing superior corrosion protection compared to “all makes” alternatives. In particular, they help prevent scaling in aluminum components and seal degradation as well as higher thermal stability ensuring proper functioning of water pumps and thermostats. Furthermore, manufacturer-specific coolants contain additives which slow nitrite depletion rates – an indicator of quality engine coolant performance and health.

Types

When checking engine coolant levels, it is essential to keep in mind that different colors of fluid exist. Consult your vehicle owner’s manual and select an engine coolant which best meets the needs of your car – choosing an incorrect type may lead to engine overheating and damage if chosen incorrectly.

Engine coolants come in various hues, such as green, orange, pink and blue. Constructed of either ethylene glycol or propylene glycol and water with corrosion inhibitors phosphates or carboxylates as additives to protect from rusting as well as chemical reactions at higher temperatures, engine coolants come in an assortment of hues for easy identification and selection.

Your car’s need for engine coolant will depend on manufacturer guidelines and your local climate, with preventive maintenance guidelines such as flushing it at regular intervals to help preserve engine and cooling system life.

Importance

Engine coolant (or antifreeze) plays an integral part in keeping the temperature of your engine operating within its proper range and protecting against corrosion and clogging.

Your engine would quickly overheat without its cooling system, as engine coolant soaks up excess heat and transfers it to the radiator for cooling by airflow from your car’s fan. This ensures its internal temperatures stay at reasonable levels during winter and help protect it against boiling over in summer.

If your engine is overheating, power may decrease or it may completely stop working altogether. If the coolant levels in your car have dropped too low to function effectively, do not hesitate to reach out and arrange an appointment for service with us as soon as possible.
