Difference between Dex-Cool and regular antifreeze

Are you looking to top off your car with antifreeze before the winter? This is always a good idea, but if you are doing it yourself you may be wondering which antifreeze is right for your car and what’s the difference between Dex-Cool and regular antifreeze? We will answer all these questions and more!

Pouring Dec-Cool coolant into a GM vehicle Do Chevy and GM vehicles use a particular type of coolant?

For a couple 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. The main way to tell the difference between Dex-Cool and regular antifreeze is that Dex-Cool is typically orange, whereas antifreeze is usually green.

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 owner’s manuals put the change interval at 5 years or 100,000 miles or even longer for Dex-Cool.

Mechanic working on a car with a wrenchCan you mix other coolants with Dex-Cool?

Technically, you can mix coolant types, but before you go ahead and do it, let’s cover some things. Firstly, Dex-Cool and traditional anti-freeze don’t mix well. Though they can work together in a pinch, after extended use, they can react and create a gel, which can be very damaging to multiple components of your cooling system.

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.

Why is your coolant low?

Before we send you on your way, let’s look into the heart of the issue. Why is your coolant low in the first place? This question could require a mechanic to answer. It may be something as simple as a leak, but it could also be the first symptom of a much more major problem. If your coolant level seems to drop over the course of a week or even a month, you should take it to a trusted mechanic.
