Using dexcool coolant in a audi6/19/2023 ![]() ![]() This could lower the efficiency of your vehicle’s cooling and even cause overheating, which may cause severe engine damage. This could cause chemical reactions that result in a gel-like substance or sludge, clogging the radiator and cooling system passages. It’s important to avoid mixing Dex-Cool with regular antifreeze. Using regular antifreeze instead of Dex-Cool in a vehicle that specifically requires Dex-Cool wouldn’t be the smartest idea. Can You Use Regular Antifreeze Instead of Dex-Cool? Generally, manufacturers suggest changing traditional antifreeze every two to three years or after driving 30,000 to 50,000 miles.Ĭlick here to find out if antifreeze expires. However, it is important to note that traditional antifreeze, whether it is IAT or HOAT, requires more frequent changes. ![]() Using it in a non-compatible vehicle can cause serious issues and negate any benefits of the extended lifespan. However, it’s important to note that Dexcool is not compatible with all engine types. This longer service interval can save time and money on maintenance. The OAT formulation of Dexcool allows it to last up to 5 years or 150,000 miles before it needs to be replaced. The coolant type you choose impacts not only your engine’s health and performance but also determine how frequently you should schedule coolant changes due to the differing lifespans of Dexcool and Antifreeze. How Does Coolant Influence Maintenance Schedules? ![]() However, antifreeze is more versatile than Dexcool and can be used in a wider range of vehicles without the risk of damage that could happen if using the wrong coolant. This means more maintenance and costs for your vehicle over time. This combination helps protect against corrosion and also makes the coolant last longer.Īntifreeze is not as long-lasting as Dexcool, so it usually needs to be replaced every two to three years or 30,000 to 50,000 miles. Newer types of antifreeze now use HOAT, which is a mixture of organic acids and inorganic salts. These types of coolants are widely accepted in the industry because they are compatible with various types of vehicles and cooling system materials. Antifreeze coolants that are more traditional use inorganic salts, such as silicates, phosphates, and borates, as their primary corrosion inhibitors. It is created with either IAT or HOAT, depending on the product. On the other hand, Antifreeze is a type of engine coolant that is usually green or yellow and can be used for different vehicles. As a result, it’s not advisable to use Dexcool in a vehicle that isn’t explicitly compatible with it. This is because its OAT-based formula could have negative effects if combined with other coolants, possibly leading to damage of the cooling system. It’s important to be aware that Dexcool is only appropriate for certain types of vehicles, primarily GM models from 1996 and beyond. This longer lifespan can be beneficial in terms of scheduling maintenance and saving money. It can last up to five years or 150,000 miles before needing a replacement, which is much longer than traditional coolants. The OAT formulation of Dexcool creates a protective layer that helps prevent corrosion and cavitation in the engine’s metal components, providing more extended protection.ĭexcool is an antifreeze product that stands out due to its bright orange/red color. Unlike traditional coolants, Dexcool doesn’t contain silicates or phosphates that can cause scaling and deposits in the cooling system. Dexcool is based on Organic Acid Technology (OAT), which uses organic acids as primary corrosion inhibitors. General Motors (GM) developed a specialized engine coolant called Dexcool. Meanwhile, Antifreeze is a general term used for coolants that can work with a wider range of vehicles and may be either Inorganic Acid Technology (IAT) or Hybrid Organic Acid Technology (HOAT) coolants. Dexcool is an Organic Acid Technology (OAT) coolant designed for use in GM vehicles manufactured from 1996 onwards. Although they both share the same purpose, to keep your engine from overheating and freezing, their compositions and best use cases significantly differ.Īlthough both Dexcool and Antifreeze are engine coolants, they have different compositions and are best suited for different types of engines. While most of you have only heard about antifreeze when it comes to engine coolants, there’s another name that you should be familiar with, especially if you own a more recent General Motors (GM) vehicle – Dexcool. ![]()
