Toyota employs HOAT, or Hybrid Organic Acid Technology, coolant. This coolant, which is red in color, is designed to safeguard all engine metals, including aluminum.
Additionally, it contains corrosion inhibitors to help prevent rust on your radiator. This kind of coolant is suitable for use in all Toyota models as well as other makes and models of automobiles.

What type of antifreeze does Toyota advise?
A new generation of ethylene glycol-based coolant, Genuine Toyota Super Long Life Antifreeze/Coolant is pre-diluted 50:50 with de-ionized water for freeze protection to -34F. Long-life hybrid organic acid technology was used to create a coolant that is non-silicate, non-amine, non-nitrite, and non-borate.
Will Toyota require certain antifreeze?
Every automaker, including Toyota, has created its own coolant or calls for a particular coolant that is specific to obvious years and models. Coolants come in a variety of colors, including blue, red, yellow, purple, green, and orange, to assist you distinguish between them.
Which antifreeze is red in color?
Dexcool is the brand name for red antifreeze, which lasts longer than other varieties. After the development of organic acid technology (OAT), which is discussed below, inorganic acid technology (IAT) was used to create several colored antifreeze compositions (mainly orange colored antifreeze formulations were produced by this technology). Later, the IAT and OAT were combined to create the hybrid organic acid technology (HOAT). The creation of red antifreeze is the result of this hybrid technology. Red antifreeze is more stable and extends the life of the water pump when compared to green antifreeze and other antifreeze substances from earlier generations.
Is Toyota red and pink coolant interchangeable?
The Toyota’s coolant needs to be changed, but you’re not sure which is better: Toyota Red Long Life Coolant or Toyota Pink Super Long Life Coolant. While they appear to be similar, there are some distinctions between the two major coolants that Toyota offers.
Is Toyota Pink Coolant Just Premixed Red?
Toyota Pink Coolant is not merely Red premixed, though. The OAT (organic acid technology) in the pink coolant normally has a longer service life. On the other hand, the red coolant uses an IAT (inorganic acid technology) and is thought to be more “traditional” while still lasting longer than some other coolants on the market.
What Are the Ingredients of Each Coolant?
Pink Super Long Life Coolant from Toyota:
- Salicylic Acid (111-20-6)
- Water (7732-18-5)
- Epoxy Glycol (107-21-1)
- Potassium Oxygen (1310-58-3)
- Diacetyl Glycol (111-46-6)
Red Long Life Coolant from Toyota:
- Inorganic Salt Hydrated (1310-58-3)
- Salted Orange Acid (532-32-1)
Which Toyota Coolant is the Longest Lasting?
According to Toyota, Pink Coolant needs to be changed every 100,000 km (60,000 miles) or 5 years after the factory fill, or up to 160,000 km (100,000 miles) or 10 years. Every 50,000 km (30,000 miles), or every two years, the red coolant needs to be replaced because it has a much shorter lifespan.
Which Toyota Coolant is the Cheapest?
Toyota Pink Coolant is considerably more expensive even if it lasts longer than Red. This is in part because Toyota Red is not pre-diluted, whereas it is only offered as a 50/50 pre-mixed mixture.
Is Toyota compatible with Prestone coolant?
CONDITIONAL INFORMATION It is specifically designed for use in Toyota, Lexus, and Scion vehicles*. Prestone 50/50 Prediluted Antifreeze/Coolant for Toyota Vehicles. The #1 Branded Engine Protection Prestone prevents corrosion from spreading, enhancing the performance and extending the lifespan of a vehicle’s cooling system.
Toyota uses red coolant, right?
The choice of pink or red Toyota coolant depends frequently on how old the car is. The red solution has a triazole and molybdate to protect copper and other components, whereas the pink product is not designed to protect the metals present in non-aluminum radiators.
The pink coolant is what your modern Toyota uses right out of the factory. As of the early 2000s, it was installed in the majority of vehicles. If you decide that “long life is good enough for your purposes,” the red is acceptable for replacement if you need to flush.
Mazda FL22
Mazda FL22 is your initial choice. Although it is a premixed 55/45 gallon, your Toyota motor can still use it.
Your engine’s antifreeze system will be cleaned of debris, corrosion, and soiled-old fluids before receiving a fresh, concentrated liquid.
Mazda can freeze at -43 degrees Celsius and has a boiling point of 132 degrees Celsius.
Zerex Asian Premixed 50/50 Gallon
You can also try Zerex Asian Pre-mixed 50/50 gallon as an alternate coolant. The Toyota pink Super Long Life Coolants recipe was altered by the Valvoline brand to become a 50/50 Pre-Mixed Formula Antifreeze, emphasizing the position of the automaker.
The advantage is that you may purchase the same product with almost exact ingredients for almost half of what you would have to pay a Toyota dealer.
This product promises to guard against rust and corrosion in antifreeze systems. Additionally, the absence of silicate and borate allows for the avoidance of scale deposition.
Motorcraft Specialty Green Engine Coolant
Last but not least, a secure substitute for Toyota pink super is Motorcraft Specialty Green Engine Antifreeze. It is available at any Ford parts counter.
This 50/50 green coolant creates boiling at 129 degrees Celsius and freeze protection to -36.7 degrees Celsius when mixed with distilled water.
Can you switch to red coolant from green?
Know that green antifreeze is the older variety. That antifreeze was an outdated variety whose glycol shelf life was maybe three years. Therefore, you should replace the coolant perhaps every three years or every 15,000 miles. Red is one of the many colors that the contemporary coolant is available in. It frequently has a five-year or 150,000-mile lifespan. So using it is superior antifreeze.
Now, if you mix them—which is against their intended use—you won’t experience an explosion or anything like because it’s not like mixing an acid and a base. The problem is that when you mix them, any machine that mechanics use to determine the freeze point will give you incorrect readings. Therefore, your reading may be inaccurate if someone attempts to determine whether you have enough antifreeze in your system so, for example, it won’t freeze in the winter. You can wind up cracking your engine if it gets very cold. In other words, you should stick to the coolant that the car was designed for. If your vehicle is older, say, and it originally came with green coolant, you can flush it out completely and replace it with the newer type after putting 150,000 miles or five years on it. If you wish to do that, it is entirely backwards compatible. However, mixing them is not a smart idea and you should avoid doing so. Consider using YourMechanic if you want the proper coolant added for you. To carry out this service, they will be able to visit your house or place of business.
What occurs if I substitute green coolant for red?
Because antifreeze is antifreeze, you might imagine that mixing two different types of antifreeze won’t harm your car. Wrong! Although green and red antifreeze are created from different compounds, they function radically differently even if they are ultimately intended to accomplish the same task.
In actuality, combining green and red antifreeze would result in a thick gel that wouldn’t effectively flow through your cooling system. This may lead to overheating and damage to various cooling system components in your car.
Don’t even try to drive your car if you accidentally mix these two types of coolant together. As soon as you can, flush your cooling system (we’ll show you how to do this later in this post) if you want to have any chance of saving your cooling system.
The meaning of red coolant
The HOAT process is used to make red antifreeze (Hybrid Organic Acid Technology). There are two varieties of red antifreeze on the market. They are designed for Asian, European, and Japanese automobiles. This kind of antifreeze is suitable for Nissan, Hyundai, Toyota, and Honda automobiles. The most common red coolant is known as “Dexcool.” Its long lifespan is four years or such. Red antifreeze typically turns pink when combined with water in cooling systems.
