Can You Mix Dex Cool With Green Antifreeze?

Yes, you can mix Dex-Cool with green antifreeze. There are a few things to keep in mind when doing so, however.

First, you should always check your vehicle’s owner’s manual to see what type of antifreeze it recommends.

Second, mixing different types of antifreeze can decrease the effectiveness of each one. Therefore, it’s important to use the same type of antifreeze in your vehicle that is already present.

  • Begin by checking the coolant levels in both the Dex-Cool container and the green antifreeze container
  • If either is low, top them off so that you have an equal amount of each
  • Next, pour half of the Dex-Cool into a clean mixing container
  • Add the entire contents of the green antifreeze to the Dex-Cool and stir until combined
  • Finally, pour the mixture back into the containers, being sure to label them accordingly

Can You Mix Dex Cool With Green Antifreeze?

Most carmakers specify Dex-Cool for use in their vehicles. Dex-Cool is an extended-life coolant that contains silicate inhibitors. These inhibitors allow the coolant to last up to five years or 150,000 miles, whichever comes first.

Some automakers also approve the use of phosphate-free, hybrid organic acid technology (HOAT) antifreezes in their vehicles. These coolants contain sebacate or 2-ethylhexanoate corrosion inhibitors instead of silicates.

While most carmakers approve the use of HOAT antifreezes as a replacement for traditional green antifreeze, they do not recommend mixing the two types of coolant.

The different inhibitor packages can interact with each other and cause deposits to form on engine components. These deposits can clog cooling system passages and reduce the effectiveness of the coolant.

What is the Difference between Dex Cool And Green Antifreeze?

Most carmakers use Dex-Cool, which is an ethylene glycol coolant with organic corrosion inhibitors. It’s available in different colors, including green, but it isn’t the same as the old-fashioned green antifreeze, which was based on silicate technology. Dex-Cool can last up to five years or 100,000 miles before it needs to be replaced.

Dex-Cool Or Green Antifreeze: Which is Better?

There are a few key factors to consider when trying to decide which type of antifreeze is best for your car. The most important factor is what type of engine your car has. If you have a cast iron engine, then green antifreeze is the better option.

This is because dex cool can cause corrosion in cast iron engines. However, if you have an aluminum engine, then dex cool is the better option because it doesn’t cause as much corrosion. Another factor to consider is the climate you live in.

If you live in a cold climate, then green antifreeze is the better option because it has a higher freezing point. However, if you live in a hot climate, then dex cool is the better option because it has a higher boiling point. Ultimately, the decision of which type of antifreeze to use comes down to personal preference and what works best for your car and driving habits.

Conclusion

Yes, you can mix Dex Cool with green antifreeze. However, it is important to note that dex cool is a newer type of antifreeze and is not compatible with all types of green antifreeze. You should always consult your vehicle’s owner manual or a mechanic to find out which type of antifreeze is best for your car.
