What Happens If You Mix Different Types of Antifreeze?

Understanding the Different Types of Coolant

Coolant, also known as antifreeze, is an essential component in regulating the temperature of your car’s engine and preventing overheating. It is important to understand that different types of coolant exist, and they are identified by their color.

The two main colors of coolant are green and orange (known as Dexcool). Green coolant is more common in older cars and needs to be replaced every 36,000 miles or three years. On the other hand, orange coolant is formulated to provide cooling coverage for up to 150,000 miles before it needs to be replaced. However, its actual lifespan may not live up to that promise. There are also less common colors of coolant available such as blue, pink, and gold, and it is important to check which one your specific vehicle requires.

The Effects of Mixing Green and Orange Coolant

Mixing different types of coolant can be extremely damaging to your engine and can shorten the lifespan of the coolant. This is especially true when green and orange coolant is mixed, as it can cause the engine to overheat. When the two coolants are mixed, a gelatinous substance is formed which can clog the cooling system and lead to serious damage.

It is essential to always check the type of coolant required for your car or consult the owner’s manual to avoid problems. When it comes to replacing coolant, it is important to completely flush the system and use the recommended type of coolant to avoid any issues.

In conclusion, mixing different types of coolant can lead to severe problems, and it is important to always use the correct type of coolant for your car. Regularly checking and maintaining your car’s coolant system can help ensure your car runs smoothly and avoids any costly repairs.

Is it Safe to Mix Coolants?

Tips for Safely Mixing Coolants

Mixing different types of coolant in your car can cause serious damage to the engine and shorten the lifespan of the coolant. However, there may be situations where you need to mix coolants, such as when topping up the coolant level or performing a coolant flush. If you need to mix coolants, follow these tips to do it safely:

  1. Use the same type of coolant – Make sure that the two types of coolants you are mixing are compatible. The types of coolant are identified by their color, and the two most common colors are green and orange (known as Dexcool). Mixing green and orange coolants is not recommended, as it can cause the formation of a gel-like substance that can clog the cooling system and lead to engine damage.
  2. Check the compatibility chart – Some coolant manufacturers provide compatibility charts, which will tell you which types of coolant are compatible and which are not. Make sure to consult the chart before mixing coolants.
  3. Flush the system – If you are changing coolants, make sure to flush the system thoroughly before adding the new coolant. This will help remove any remaining old coolant and contaminants that could cause damage to the engine.
  4. Follow the recommended mixing ratio – If you are adding coolant to top up the level, make sure to follow the recommended mixing ratio. Adding too much or too little coolant can affect the performance of the cooling system.
  5. Check the pH level – Coolants have a pH level, which can affect their performance and compatibility with other types of coolant. Make sure to check the pH level of each coolant type before mixing them.
