In 2007-2008, GM settled in the class action lawsuits and had to compensate owners for the damage, but the 2009 bankruptcy made the payout more complicated. It’s essentially a HOAT solution that supposedly has a longer service life.ĭex-cool has sparked a lot of controversies when it was determined that it causes manifold gasket failures and acts as a plasticizer, ruining nylon and silicone rubber. Any price and availability information displayed on at the time of purchase will apply to the purchase of this product.ĭex-cool is a proprietary antifreeze solution made by GM for vehicles 1995 and newer but is also used in some Ford and Chrysler vehicles. Product prices and availability are accurate as of the date/time indicated and are subject to change.

The IAT antifreeze should be bright green, but manufacturers also used different shades of green and blue to color their solutions. The original green has been used for a very long time, but manufacturers began to phase them out in the ’90s in favor of less toxic options. MPG is primarily used in food processing because of its low toxicity, MEG in for most car antifreeze solutions, while propylene glycol methyl ether is used for heavy-duty diesel engines and is the most volatile.Ĭommonly known as the ‘original green’ ethylene glycol solution is made out of distilled water, MEG, and additives that stabilize the highly toxic and corrosive substance. The three most prominent IAT antifreeze bases are MEG (mono ethylene glycol), MPG (mono propylene glycol), and propylene glycol methyl ether. IAT stands for Inorganic Acid Technology, an abbreviation that can quickly tell you whether the antifreeze is compatible with your vehicle, as manufacturers indicate what antifreeze you should use. An undiluted solution requires you to add about 50% distilled water in the mix, but it’s easier to carry and cheaper to ship, while a diluted solution can be poured directly into the car, which is especially handy when you have to top up while you’re on the road. Diluted vs Undiluted AntifreezeĪntifreeze comes in diluted and undiluted variants for convenience. When you’re buying antifreeze, the color can narrow down your search, but you should really check the chemical composition to be certain it’s the right one for your vehicle. The reality is that antifreeze is colored to make it more visible inside the coolant reservoir and make spills easier to identify. Some people will tell you that blue color is used for ethylene glycol, green is for propylene glycol and red is for organic acid-based antifreeze, and while there is some truth to it, it’s far from a reliable way of telling what the antifreeze is made of. As newer vehicles have aluminum radiators and the notion of regularly replacing antifreeze doesn’t exist, you can really damage your car by using older types of antifreeze. This wasn’t the problem at the time because radiators were copper plated, but those made out of aluminum needed to be regularly flushed. In an enclosed coolant system with no leaks, the antifreeze can last forever, but the additives fade, and the antifreeze can corrode components. It’s the most toxic and corrosive mixture that is stabilized by additives. The conventional antifreeze we can still use today became available in 1926 as an ethylene glycol solution. To give you a better understanding of the subject, I’ll explain the differences between antifreeze types, their significance, and why mixing antifreeze is not a good idea. Mixing the chemicals can cause a chemical reaction that can turn the antifreeze into acid. To differentiate between chemical compositions, manufacturers intentionally choose specific colors. Should you go ahead and pour in the antifreeze? You’ve got a bottle of coolant to top it up, but as you open the coolant reservoir, you realize the antifreeze colors don’t match.
You’re under the hood checking fluid levels when you notice your coolant is low.
