Is Dex Cool a HOAT Coolant?
Dex Cool is a coolant developed by General Motors (GM) for use in their vehicles. The debate surrounding whether Dex Cool is a HOAT (Hybrid Organic Acid Technology) coolant or not has led to confusion among car owners and technicians. In this section, we will delve into the history, composition, and characteristics of Dex Cool to determine its classification as a HOAT coolant.
History of Dex Cool
Dex Cool was first introduced in the 1990s as a replacement for traditional ethylene glycol (EG) coolants. It was developed by GM as a more environmentally friendly and durable option for their vehicles. Dex Cool was designed to provide better corrosion protection, improved heat transfer, and a longer lifespan compared to traditional EG coolants.
The early versions of Dex Cool were formulated with a combination of organic acid technology (OAT) and ethylene glycol (EG) to provide improved performance and protection. However, in 2000, GM introduced a new formula for Dex Cool that replaced EG with a new organic acid technology (OAT) base.
Composition of Dex Cool
Dex Cool is a proprietary coolant developed by GM, and its exact composition is not publicly disclosed. However, based on various studies and analyses, it is believed that Dex Cool is a hybrid organic acid technology (HOAT) coolant.
A HOAT coolant is a type of coolant that combines the benefits of OAT and EG coolants. It uses a combination of organic acids, such as silicates and phosphates, to provide corrosion protection and improve heat transfer. HOAT coolants are known for their improved durability and resistance to corrosion compared to traditional EG coolants.
Studies have shown that Dex Cool exhibits many characteristics of a HOAT coolant, including:
