What Color Is Dex-Cool Engine Coolant?

Questions and Support
1

I’ve been trying to determine the color of Dex-Cool engine coolant as I want to make sure I’m using the right type in my Chevrolet. From what I’ve read, Dex-Cool is usually a distinct orange or peach color, but I’ve come across some discussions suggesting it can vary a bit.

Here are a few points that I’m curious about:

  • How can I tell if the coolant I have is Dex-Cool or something else, like the traditional green antifreeze?
  • Is it possible for Dex-Cool to change colors over time, and what might cause that?
  • Are there any compatibility issues I should be aware of when mixing with other types of coolant?

If anyone has experience with this or advice on identifying Dex-Cool, I’d really appreciate your input! Thanks for any help you can provide.

I’ve heard some recommend DEX-COOL over traditional green coolant because of its longer life. Anyone else have experience with that?

That’s true! DEX-COOL can last up to five years or 150,000 miles, if maintained properly. Just make sure to regularly check levels.

Speaking of which, if you see your coolant turning brown or murky, that’s a sign to flush it out. Don’t ignore it!

I actually mixed DEX-COOL with green coolant once. The resulting sludge was scary! Lesson learned: always check the color!

Yikes! Mixing can lead to serious engine issues. It’s vital to stick with the manufacturer’s specifications.

Can anyone explain why DEX-COOL is orange? Is there a chemical reason behind the color?

Great question, mary28! The orange color mostly comes from a specific dye used in the coolant. It’s meant to be easily identifiable.

Sometimes I wonder if there’s a secret coolant color code we’re all missing. Imagine if all fluids had unique colors!

Haha, that would be wild! But let’s stick with DEX-COOL’s orange for now—it’s a classic!

DEX-COOL is typically orange or pink, but beware! Mixing it with green or blue coolants can cause gelling, which is a disaster for your engine. Stick with DEX-COOL if that’s what you have.

14

That’s right! Always read the labels. If you’re ever unsure, it’s best to just flush and refill completely rather than risk a bad combination.

15

I’ve heard some people mix DEX-COOL with conventional coolants and claim it works fine. But I’d stay away from that experiment—my friend had a bad experience.

16

It’s really not worth the risk! DEX-COOL needs special handling. Always flush the system when switching types to avoid any issues.

Mixing colors is like mixing oil and water—bad idea! DEX-COOL works best when it’s pure. Regular maintenance can extend its life. Anyone have tips for the flushing process?

18

Definitely! Use a cooling system flush solution to clean it thoroughly before refilling with fresh DEX-COOL. Follow the manufacturer’s instructions for best results.

Isn’t it ironic that the color coding is supposed to help us, but it can confuse people who don’t know? Just because it’s green doesn’t mean it’s safe to mix with DEX-COOL!

True that! DEX-COOL’s specific formulation is really what you want under that hood. Mixing can create challenges that are tough to handle.
