Can You Mix Different Types of Coolant?

Can You Mix Different Types of Coolant?

Everyone knows that their car uses anti-Freze, but did you know that there are different types of antifreeze there? If you know you bought it differently and want to know if you can mix you, come to the right place.

You tell them everything you need to know about different types of antifreezes and know what happens if you decide to mix them up. If you’re in a pinch, I’ll let you know what you can do. By the end, you’ll be ready to get your car back on the road!

Can You Mix Different Types of Coolant? You should never mix different types or colors of coolant if you are not an expert on the chemical composition and reactions of the various types. Stay on the safe side and follow the manufacturer’s recommendations. Using the wrong type of coolant can lead to expensive repair costs.

Now, I will take a closer look at why it’s not a good idea to mix different types of coolant. Different types of anti-bubbling
There are many different anti-freeze varieties, but the two main types used in vehicles are the orange anti-frost, which uses traditional green anti-freeze and dexole. Colors can be a good starting point for finding the type of coolant you have, but colors can be misleading.

For example, not all vehicles with orange anti-frost frost. Also, if you want to insert DexCool into a regular orange antifrost, ask for the problem. Always check twice, triple check, vehicle coolant type is not just defeated by color. If you can’t reliably find out what anti-freeze your vehicle has, it’s best to complete a coolant spool and find out what’s there. Always check the specifications of the engine type!

Green coolant

• Green coolant is the most common type of anti-frost on vehicles.
• Green Antifreeze doesn’t take as long as orange coolant, but you should check the recommended service intervals for your vehicle before rinsing the coolant every few thousand miles.

This is because modern vehicles are getting better and have sealed cooling systems. This can take longer between changes in the liquid. Before rinsing the system, take a look at the owner’s guide and make sure it says!

Don’t forget that this interval applies to antifreeze recommended by the manufacturer. So, using something else can be expected to change the service interval.

Orange Coolant

Orange coolant is often a product named Dexcool. GM manufactured Dexcool and promised that you’d only need to flush your system every 150,000-miles if you used it. This is a much longer service life than regular anti-freeze, so you can see why its popularity surged.

The only problem is that Dexcool didn’t always work as advertised. Moreover, just because you open the hood and see orange coolant, that doesn’t mean you have Dexcool. Always double-check what kind of coolant is in your vehicle instead of relying solely on the color.

If you’ve never flushed the coolant on your vehicle, you can check the owner’s manual, if you have changed the coolant, you might be out of luck. If you don’t know, go ahead and flush the entire system before potentially mixing the wrong type of coolant.

Less Common Types

While green and orange anti-freeze products are by far the most common, you can also find vehicles that use a pink, blue, or gold anti-freeze. This largely comes down to your vehicle’s manufacturer and what kind of coolant they decided to put in the vehicle.

The differences between these coolants vary, but it almost always comes down to the types of additives used in each anti-freeze. They are all glycol-based, but the additives that they use make a big difference.

If you can’t find the exact coolant that your vehicle uses, stop by the dealership or flush the entire system before adding the new coolant. Keep in mind that adding a different kind of coolant to a vehicle under warranty can void the warranty.

What Happens if You Mix Different Types of Anti-Freeze? Since there are so many different anti-freeze types, the exact results of mixing anti-freeze will vary depending on what anti-freezes you mix, but the short answer is that you should never mix different types of anti-freeze.

For instance, if you mix green and orange anti-freeze, the two different types of additives will mix and coagulate. In short, they’ll get thick and gum up the system. Not only does this shorten the lifespan of the coolant, but it can cause your engine to overheat and damage your system.

So, while there are some forums out there that claim you just need to go to the shorter lifespan of the two coolants – this is 100 percent false, and it can severely damage your engine. Don’t risk it, and don’t mix different types of coolants.

Keep in mind we’re talking about types of coolant here – not brands. Most times, the brands simply switch the names but use the same formulas, so as long as they’re the same type, you’re still in great shape.

What if You’re in a Pinch?
If you’re stuck out in the middle of nowhere and need to top off your coolant to get where you’re going, you have better options than mixing the wrong types of anti-freeze. While mixing the anti-freeze might get you where you’re going without any problems, you’re taking a risk.

Instead, all you need to do is add some distilled water to top off your system. While diluting the system with more water lowers the boiling point and raises the freezing point, a system with only 10 percent anti-freeze and 90 percent water will still only have a freezing point of 26 degrees Fahrenheit.

So, as long as you’re not driving during a snowstorm, you should be alright. If you read that and thought, “I want the lowest possible freezing point, so I’m going to add 100 anti-freeze and no water,” you’re mistaken. Adding water actually lowers the freezing point and glycol – to a point. The ideal anti-freeze to water ratio is 60 percent anti-freeze and 40 percent water.

But if you’re in a pinch, add water – not a different kind of anti-freeze. Not only will you avoid problems, but you’ll have no problem getting where you’re going either.

Final Thoughts On Mixing Anti-Freeze
If you’re thinking about mixing anti-freeze to save a few bucks – don’t. While you might save $20 to $40 now, it can easily cost you a couple hundred to a couple thousand dollars down the road.

If you’re worried and trying to save a little money, just add distilled water to the system. Distilled water is not the same as tap water, as tap water has chemicals that can lead to corrosion inside your cooling system.

But distilled water is cheap – you can usually find it for as little as $1 per gallon. Don’t take the risk by mixing anti-freeze types, it’s just not worth it.
