The Mazda FL22 may not be the most popular coolant, but it is a high-quality product. Especially if you own a Mazda car, this is a great pick. It is designed for longevity and has the necessary ingredients to protect your engine and keep it running at its peak performance. 

The coolant that we are talking about in this short review is categorized as a Type FL22. It is a long-life ethylene glycol coolant. It is in a premixed formula and contains deionized water:

1. Boiling Point 

Water has a boiling point of 100°C (212° F). After reaching this temperature, the engine overheats, negatively affecting its performance. The Mazda FL22 coolant has a boiling point of 135° C. It ensures a superior cooling capacity to keep the engine performing at its best. 

2. Freezing Point 

The freezing point of water is 0° C or 32°F. Meanwhile, the Mazda FL22 coolant has a freezing point of -43° C. This means that it will take a freezing temperature before the coolant freezes. When such happens, it is difficult for the engine to run, thus reducing its performance. 

3. Base Fluids 

As common with many other coolants, the base is a combination of water and ethylene glycol. The latter is a transparent and viscous fluid that reacts with ethylene oxide in the water. It is also common in deicing solutions. It is the component that is largely responsible for the main function of an antifreeze – to prevent overheating and freezing. 

4. Compatibility 

You can use the Mazda FL22 coolant in a wide array of Mazda vehicles. Specifically, they are compatible with Mazda CX-3, CX-5, CX-7, CX-9, Mazda 2, Mazda 3, Mazda Speed 3, Mazda 5, Mazda 6, and RX-8, among others.

What We Do Not Like 

  • Hard to Find: This is not one of the most popular coolants in the market. So, finding it can be quite a struggle these days. Even online reviews are scarce, making it challenging to learn from the real-life experiences of other people. 
  • Quite Expensive: The price of this coolant can be an issue for some buyers. While it is a bit expensive, the cost is justifiable. Aside from being made by a reputable brand, it uses high-quality ingredients and delivers a high level of effectiveness. With all its benefits, this antifreeze is worth every dollar.

Got questions about the Mazda FL22 coolant? We’ll answer some of them below:

What Is the Color of the Mazda FL22 Coolant? 

The color of this coolant is green. The color of coolants varies depending on the main ingredient used or its type.

When Should You Replace the Mazda FL22 Coolant? 

In the case of older car models, the manufacturer recommends replacing the coolant after every 60,000 miles or five years, whichever comes first. It is best to add a sticker on the reserve tank to note the date when you replaced the coolant. This way, it is easy to know when the coolant is due for a replacement. 

Does the Mazda FL22 Contain Harmful Ingredients? 

Yes, this coolant has harmful ingredients. It has ethylene glycol, which can be hazardous. Avoid getting in contact with skin and eyes. In case of accidental contact, rinse with water immediately. When swallowed, execute first aid treatment immediately. Use the coolant only in a well-ventilated space. 

How Do You Safely Store the Mazda FL22 Coolant? 

Keep the coolant in a cool, dry, and dark place. Store it away from any flammable object or source of ignition. Tighten the lid after every use. 

Can You Mix Mazda FL22 with Other Coolants? 

Mixing coolants can result in a color change. Especially if you mix Mazda FL22 with an orange coolant, it will turn black. For the best outcomes, it is best not to mix different coolant types. Mixing coolants can clog radiators and result in gelling, which can minimize the engine’s performance. 

Will It Void My Car’s Warranty? 

If you have a Mazda car, there’s no need to worry. Using this coolant will not void the warranty since Mazda also makes it. Meanwhile, for other car brands, make sure to check with the manufacturer.

What Is an Engine Coolant?

What exactly is a coolant? Do you need a coolant for your Mazda? 

A coolant or an antifreeze is crucial for maintaining a vehicle’s peak performance despite the conditions of the external environment. It is in the form of a liquid that runs on the engine to lubricate the moving parts. It also protects different components against damage, such as the cylinder, head gasket, and water pump. 

While there are endless choices for an engine coolant, most of them have a similar composition. Often, it is made of a combination of 50% water and 50% ethylene glycol. If the coolant is for industrial applications, propylene glycol replaces ethylene glycol as the base material. 

The main function of glycol in a coolant is to act as an antifreeze. It ensures that the fluid will not boil in scorching temperatures and will not freeze when extremely cold. It stabilizes the engine’s temperature. This is important when driving long distances with fluctuating temperatures. 

Conclusion – FL22 Coolant (Mazda)

The Mazda FL22 is a high-quality coolant. It protects the engine against premature wear by making sure that it does not overheat or freeze in extreme temperatures. It has a freezing point of -43° C and a boiling point of 132°C. The coolant is made of an equal mixture of water and ethylene glycol. 

While it is quite hard to find nowadays, this is an exceptional antifreeze. More than being made by an exceptional brand, it has an extended life, does not require mixing, manages temperature fluctuations, and inhibits rust. It does not contain silicates so that it won’t harm the cooling system’s rubber components.
