What Is Universal Coolant? Pros and Cons Explained
Universal coolant is a versatile solution designed to meet the diverse needs of various vehicles and cooling systems. This type of coolant is formulated to be compatible with all types and colors of coolant, making it an excellent choice for those who may not know the specific coolant requirements of their vehicle. This article will discuss everything you need to know about universal coolant.
What Is Universal Coolant?
Also known as all-makes/all-models (AMAM) coolant, universal coolant is compatible with all colors and types of coolants. As mentioned, if you are unsure of which type of coolant color or type to use in your vehicle, this is the easiest option you can consider regardless of the manufacturer’s recommendations.
Universal coolant is typically dyed either yellow or amber, but the color can vary depending on the manufacturer.
What Is Universal Coolant Made of?
Universal coolant is typically made of a base fluid, such as ethylene glycol or propylene glycol, along with a blend of additives. The additives in universal coolant can vary depending on the manufacturer.
Pros and Cons of Using Universal Coolant
Let’s inspect both sides of the coin.
Pros of Universal Coolant
Compatibility: Universal coolant is compatible with all types and colors of coolant, making it convenient for use in a wide range of vehicles.
Convenience: With universal coolant, you don’t need to worry about using the wrong type of coolant for your vehicle. Although the color of antifreeze doesn’t really matter, mixing different colors and types can cause different issues to your vehicle.
Cost-effective: Since universal coolant can be used in various vehicles, you don’t need to buy different types of coolant for different vehicles. This can be really beneficial if you have multiple vehicles to maintain.
Easy to find: Universal coolant is widely available at auto parts stores and can be purchased without the need for special ordering.
Cons of Universal Coolant
Performance: Universal coolant may not provide the same level of performance or specific benefits as manufacturer-specific coolant. Some vehicles may require a specific type or color of coolant, and using universal coolant may not meet those requirements.
Cooling system compatibility: While universal coolant is designed to be compatible with most cooling systems, there may be some exceptions, so it’s important to check compatibility before use.
So, Is Universal Coolant Really Universal?
Well, while universal coolant is designed to be compatible with a wide range of vehicles, our experience suggests that it may not be suitable for every vehicle. Factors such as specific manufacturer requirements, coolant system design, and compatibility with existing coolant in the system can affect the suitability of universal coolant for a particular vehicle.
As explained, universal coolant can be a convenient option for many drivers, especially those who are unsure of their vehicle’s coolant requirements or who service a variety of vehicles.
However, it’s always a good idea to check your vehicle’s owner’s manual or consult with a professional mechanic to ensure that universal coolant is suitable for your vehicle.
Why Do Some Mechanics Insist on Mixing Universal Coolants?
We’ve seen some mechanics insist on mixing universal coolants because mixing different types or colors of coolant can sometimes improve compatibility, especially in older vehicles or vehicles with unknown coolant histories.
In addition, mixing universal coolants can be convenient, especially in situations where a specific coolant type or color is not readily available. It allows mechanics to use what they have on hand without having to wait for a specific coolant to be ordered.
Can Universal Coolant Be Mixed with Dexcool?
Mixing universal coolant with Dexcool, which is an extended-life coolant (OAT), is generally not recommended.
Dexcool is specifically formulated to work with the materials used in General Motors vehicles and is not recommended for use in other vehicles. If you need to top up or replace the coolant in your vehicle and you’re unsure about compatibility, it’s best to flush the cooling system and use the coolant recommended by your vehicle’s manufacturer.
Can I Use Universal Coolant in Any Car?
Well, as we explained earlier, the word “universal” can be really confusing as universal coolant is not suitable for certain vehicles, including newer vehicles under warranty, vehicles with specific coolant requirements, mixed coolant systems, high-performance or specialized vehicles, and vehicles with contaminated coolant systems.
Using universal coolant in these vehicles can lead to compatibility issues, warranty voidance, or inadequate cooling system protection.
