Can You Mix Different Types Of Antifreeze Together [Best Answer]

If you’ve been an expert mechanic for 30 years, then you probably know that you can mix different types of antifreeze together. However, there are a few things you should keep in mind when doing so.

First, it’s important to check the compatibility of the antifreeze you’re mixing. Some antifreezes are not compatible with each other and can cause serious damage to your engine.

Second, you should always add the antifreeze to the coolant, not the other way around. Adding antifreeze to the coolant can cause the coolant to become too thick and can damage your engine.

Third, you should always follow the manufacturer’s instructions when adding antifreeze to your engine. Overfilling or underfilling the antifreeze can also damage your engine.

Fourth, you should always check the level of antifreeze in your engine before adding more. If the level is too low, it can cause your engine to overheat. If the level is too high, it can cause your engine to freeze.

Fifth, you should always flush your engine before adding new antifreeze. This will help to remove any old antifreeze that may be in your engine and can also help to prevent any new antifreeze from mixing with the old antifreeze.

Finally, you should always be sure to dispose of any old antifreeze properly. Antifreeze can be poisonous and can cause serious health problems if not disposed of properly.

Keep these things in mind and you should be able to mix different types of antifreeze together without any problems.

Can you replace Dexcool with regular antifreeze?

Yes, you can replace Dexcool with regular antifreeze, but there are a few things you need to know before you do.

Dexcool is an ethylene glycol based coolant, while regular antifreeze is usually propylene glycol based. Dexcool has a different chemical makeup which allows it to last longer and provide better cooling than regular antifreeze. It also has a higher boiling point and can withstand higher temperatures.

However, Dexcool is also more expensive than regular antifreeze. If you are on a budget, you can definitely replace Dexcool with regular antifreeze, but keep in mind that you will need to change it more often.

Another thing to keep in mind is that Dexcool is not compatible with all types of antifreeze. If you are mixing Dexcool with regular antifreeze, make sure to use a 50/50 mix.

In general, it is best to consult your car’s owner’s manual before making any changes to the type of antifreeze you are using.

What happens if you mix orange and green antifreeze?

If you mix orange and green antifreeze, the results can be catastrophic. The orange antifreeze is typically used in older cars, while the green antifreeze is used in newer cars. The two types of antifreeze are not compatible and can cause serious engine damage if mixed.

The orange antifreeze is made with ethylene glycol, while the green antifreeze is made with propylene glycol. These two chemicals are not compatible and can react with each other, causing a chemical reaction that can damage your engine.

If you mix orange and green antifreeze, the coolant will become thick and sludgy. This can clog your radiator and cause your engine to overheat. The coolant will also turn a bright orange color, which is an indication that it is no longer safe to use.

If you accidentally mix orange and green antifreeze, it’s important to flush your cooling system immediately. This will remove the contaminated coolant from your car and prevent further damage to your engine. You should then take your car to a mechanic to have the cooling system flushed and the antifreeze replaced.

What happens when you mix Dex-cool and antifreeze?

When mixing different types of antifreeze, it’s important to know what each does. Dex-cool is an antifreeze designed for use in General Motors vehicles. It’s a propylene glycol based coolant, which means it’s less likely to cause corrosion than traditional ethylene glycol based coolants. It also has a higher boiling point and a lower freezing point than ethylene glycol coolants.

Antifreeze is an important part of your vehicle’s cooling system. It helps to keep the engine cool and prevents the coolant from freezing in cold weather. The coolant also helps to keep the engine clean and free of rust.

When mixing Dex-cool and antifreeze, it’s important to use the correct proportions. If too much Dex-cool is used, it can cause corrosion. If too much antifreeze is used, it can reduce thecoolant’s ability to protect the engine.

The best way to mix Dex-cool and antifreeze is to use a 50/50 mix. This means that half of the coolant will be Dex-cool and the other half will be antifreeze. This mix will provide the best protection for your engine.

If you’re unsure of the proportions, it’s best to err on the side of too much antifreeze. This will ensure that your engine is protected from freezing and corrosion.

What is Dex-Cool compatible with?

Since Dex-Cool is an ethylene glycol coolant, it is compatible with all materials that are compatible with ethylene glycol. This includes most metals, plastics, and rubbers. Dex-Cool is not compatible with aluminum, however. It is also not compatible with cast iron or copper.
