It is innate to do your research if you plan to buy, flush, or replace the coolant in your car. There are copious colors of coolants to assist distinguish each including green, blue, red, purple yellow, and orange. Give the advisors at Coggin Nissan at the Avenues a call at 9047478567 or schedule service online and let one of our technicians and service advisors handle your coolant flush.Įvery vehicle manufacturer, encompassing Nissan has developed its own coolant or requires a specific coolant that is unique to disparate years and models. You can invest ready-made mixtures of coolant that already have water distinct, or you can invest full-strength antifreeze which needs to be diluted with distilled water before being distinct to the engine system. They need to be combined to create the essential coolant. Keep in mind, you never want to pour antifreeze or water by themselves into your engine system. Interestingly enough, this isn't the first time you've heard of ethylene glycol as it is the fundamental ingredient in the prominent term "antifreeze". In colder climates, this is extremely difficult. Water is used to transfer heat while ethylene glycol is used to lower the bitter point of the liquid. Liquid coolants are generally half water and half ethylene glycol. The growth in the number of available antifreeze/coolant formulations has forced manufacturers to use different color dyes for different types of antifreeze/coolants.Coolant, as it relates to vehicles, is typically a liquid or gas substance used to regulate the temperature of your engine. Since both water and antifreeze/coolant are colorless, manufacturers add a colored dye to the solution so the user can differentiate between it and other under-hood fluids and more readily know if a heavy duty engine is experiencing a coolant leak. These coolants typically provide 600,000 miles or 12,000 engine hours of service life, but their performance life can be drastically reduced if contaminated with nitrite-containing coolants. Organic Acid Technology (OAT) has no nitrite added. The ELC antifreeze/coolants use organic acids (organic additive technology), nitrite and/or molybdenum as part of their inhibitor package and are referred to as Nitrited Organic Acid Technology (NOAT) antifreeze/coolants. Nitrited Organic Acid TechnologyĮxtended Life Coolant (ELC) does not require a supplement (referred to as an extender) until 300,000 miles or 6,000 engine hours to achieve the full 600,000 miles or 12,000 engine hours of service life. These formulations are not compatible with the extended interval coolant formulation of either NOAT or OAT coolants and should not be mixed with them. HOAT coolants are most commonly found dyed yellow or orange. Unlike the OAT and NOAT Extended Life Coolants (ELC), HOAT coolants, like the IAT coolants, typically require SCA added back into the system at the first maintenance interval (25,000 miles) or as specified by the engine manufacturer. Hybrid Organic Acid Technology (HOAT), which is a combination of some of the inhibitors used in inorganic IAT and organic OAT coolants, is typically based on a low-silicate, nitrite technology. However, compared to OAT and NOAT coolant formulations, the IAT coolants do require the frequent addition of SCA at an interval of 25,000 miles, or as specified by the engine manufacturer. Today, most of the “conventional low-silicate” antifreeze/coolants in the market are fully formulated with a pre-charge of SCA to protect the cooling systems of heavy duty engines against corrosion, cavitation, liner pitting, freezing and boil over. It was typical to start with a low silicate-based product design for cars and light-duty trucks, which required dilution with water, then you needed to “pre-charge” it with specific amounts of supplemental coolant additives (SCAs) to protect heavy duty engine cylinder liners from destructive pitting corrosion. The original, green-dyed antifreeze/coolants are called conventional low-silicate, but the technical name for this type of coolant and its inhibitor package is Inorganic Acid Technology (IAT).
