The Dex-cool antifreeze comes in red/ orange color. Always consult the label and user manual. For instance, Zerex Coolant has stated that their coolants are compatible with orange dex cool. Usually, labels clearly state if it is compatible with dex cool. You should check the antifreeze label if you are looking for antifreeze compatible with Dex cool. What antifreeze is compatible with Dexcool? Most times, if not regularly changed, the engine may corrode. Regular antifreeze changes color, although it doesn’t change color in aluminum engines. Dex-cool does a great job of minimizing corrosion in the engine parts for a longer time. In addition to color and composition, one can differentiate dex-cool and regular coolant by how they interact with engine materials, specifically aluminum in the engine. In addition, Dex-cool is not typically glycol-based and instead contains phosphates, silicates, and organic acids. This mixture helps to prevent overheating in the engine. On the other hand, regular antifreeze is composed of water, ethylene glycol, and methanol. Compositionĭex cool and regular coolants are different when it comes to composition properties. However, it is pretty tricky to tell with Dex-cool. The regular green antifreeze interacts with rust and changes color to let you know when it needs replacements. For example, most universal or regular antifreeze comes in c lear green or blue, while dex-cool is usually orange or red. Their color can be individually identified. The following are differences between dexcool vs regular antifreeze: Color
Difference between Dex Cool and Regular Antifreeze 200Īlthough these two fluids perform similar jobs, they are very distinct in color, composition, and how they interact with engine materials. GM resolved this issue by using a different material for their gaskets. However, GM stated that allowing air to enter the engine environment results in chemical changes to the coolant, leading to gasket leaks. In some cases, people have reported coolant leaks. These gel-like substances can damage the radiator and other components and will often require flushing to fix it. Mixing dex cool with antifreeze wrongly could form a slimy gel-like fluid that prevents antifreeze circulation and causes the engine not to cool properly. What happens after mixing dex cool with antifreeze? The additive found in dex cool prevents these from freezing or boiling. We mainly use antifreeze like dex cool instead of water because it will freeze at 32 0 and boil at 212 0. In composition, antifreeze is 1:1 water to antifreeze. Pure antifreeze boils faster than water, but combined reduces the water’s freezing point and increases the boiling point. It is not ideal for mixing water with dex cool, although distilled water can work we don’t recommend it. In addition, they will require coolant flushing or, worst cases, total replacement of the cooling system, which is very expensive. The effect of wrongly mixing dexcool and green antifreeze greatly damages many components of your cooling system.

Always ask a professional mechanic if you still need clarification about whether to mix the fluids into your radiator. However, it was labeled Dex-compatible, which assured me all would be fine. Personally, I have used the Dex-cool on my Silverado, and it worked fine.
But cars manufactured in late 1990 forward actually require a 50-50 mixture between the two fluids. Most car owners before 1998 couldn’t mix both coolants without causing any harm to the vehicle.

The obvious question is how to know what universal coolants are compatible with Dex cool. That said, wrongly mixing dexcool and universal antifreeze will produce a gel-like substance that can destroy the engine or cooling system and cause overheating. Today most universal coolant/antifreeze is compatible with Dex-cool than older green coolants. Can you mix universal coolant with dexcool? However, General Motors has noted that mixing universal antifreeze and dex cool will reduce the integrity of Dex-cool by more than 70% and require you to change fluids at regular intervals. It is generally in a 50-50 proportion shake them together and pour them into your radiator, which works perfectly. Some factors are essential to consider when mixing these fluids and will be examined in this article. If you are thinking of mixing universal coolant with Dex-Cool – You should stop and read this first to get your answer regarding can you mix universal coolant with dexcool?
