Difference between Dex-Cool and regular antifreeze

The easiest way to tell the difference between Dex-Cool and regular antifreeze is that Dex-Cool is usually orange/red, and regular antifreeze is green/blue.  Dex-Cool is made up of combinations of different phosphates and silicates as well as an organic acid technology that helps minimize corrosion in aluminum engines.  On the other hand, regular antifreeze is composed of water mixed with methanol and ethylene glycol and is designed to change color when rust or corrosion is present. Both products are used to keep your car’s engine cool but Dex-Cool is usually what you should use in your GM vehicle.

Can I use dex cool in my chevy?

Dex-Cool is designed to work with all GM vehicles 1995 & newer (GM-approved), most Ford vehicles 2011-2018, and most Chrysler vehicles 2013 & newer.  It manages engine temperature, prevents freezing, and protects the engine from corrosion.

Do Chevy and GM vehicles use a particular type of coolant?

For a couple of decades now, GM has used a type of coolant known as Dex-Cool. Despite not being called antifreeze, it still accomplishes the same task, so you don’t have to worry about replacing Dex-Cool for the winter months or anything like that.

Are there advantages to Dex-Cool?

Why did Chevy and GM make the change over to Dex-Cool? The idea was simple really Dex-Cool lasts longer than traditional antifreeze. In fact, most owners’ manuals put the change interval at 5 years or 100,000 miles or even longer for Dex-Cool.

Can you mix other coolants with Dex-Cool?

Dex-Cool and traditional anti-freeze don’t mix well. When mixed, these two products will react forming a gel that can prevent your engine from cooling properly. It can even damage multiple components of your cooling system which then must be flushed or replaced which is expensive.

For that reason, the best thing for your Chevy or GM vehicle is to stick with Dex-Cool. There are a few alternatives out there though. Currently, many coolant producers make solutions that aren’t Dex-Cool but are safe to mix with Dex-Cool. Make sure to read your manual and the label on the coolant that you would like to add thoroughly.
