In Depth Comparison

Now let’s take a deeper look into ms 12106 vs ms 90032 specs.

ms 12106 vs ms 90032 specs

Need for Mixing:

MS 90032 coolant is a concentrate product that needs mixing before use. On the other hand, OAT coolant MS 12106 is 50/50 premixed and ready to use.

MS 90032 coolant requires mixing with water before use. While MS 12106 coolant is a concentrate and does not require mixing with water. 

So, MS 12106 coolant is a waterless formula designed to be used directly in the cooling system. MS 90032 coolant is a liquid coolant that needs to be mixed with water before it can be used in the engine.

When mixing MS 90032 coolant with water, it is crucial to follow the manufacturer’s instructions. And use the recommended water-to-coolant ratio to ensure optimal engine performance and avoid damage to the cooling system. 

The recommended ratio may vary depending on the specific application, engine design, and operating conditions. And it is crucial to use the correct ratio to avoid issues such as engine overheating, corrosion, or cavitation.

Generally the ideal ratio for the mix is 1:1. Meaning you will add 1 liter of water to 1 liter of MS 12106. But remember to create the mixture before pouring it in the engine. Do not pour antifreeze directly into the engine. 

Remember that these coolants should be mixed with water only. Not with any type of transfer case fluid.

Winner: The winner of this round is MS 12106 because it is ready to use. 

Freezing Point: 

The freezing point of MS 90032 coolant is lower, whereas the freezing point of MS 12106 coolant is higher. 

As was just mentioned, the MS 12106 does not need to be mixed with water in order to function properly. The MS 90032 coolant is a liquid that requires water to have water added to it before it can be used. 

The coolant known as MS 90032 has a distinctive formulation that does not include any water. This contributes to its lower freezing point. Because of this, it is appropriate for use in situations with extremely low temperatures. 

On the other hand, MS 12106 coolant is composed of water in addition to a number of additional additives. These additives work to increase the freezing point of the coolant.

Winner: This round is also a draw. Which is better for you in terms of freezing depends on the environmental temperature. 


MS 12106 coolant being ideal for automotive and heavy-duty diesel applications. And MS 90032 coolant being great for all types of power sports vehicles.

On the matter of oat coolant ms-12106 compatibility, it is commonly used in automotive and heavy-duty diesel applications. This includes, but is not limited to, Chrysler, Jeep, Dodge, Ram, and Fiat vehicles. 

On the other hand, MS 90032 coolant is designed for use in all types of power sports vehicles.  This includes, but again is not limited to, motorcycles, ATVs, snowmobiles, and other small engines.

MS 90032 coolant is great for all types of power sports vehicles because it maintains a stable, hostile environment. It is where corrosion and bacterial growth cannot exist.

Winner: This round is also a draw because preference in compatibility will differ from person to person.


Don’t worry, your antifreeze will not evaporate. But MS 12106 coolant and MS 90032 coolant have different longevity. Because they are designed for different applications and have different formulations.

MS 90032 coolant is a premixed formula that meets the 10-year or 150,000-mile service life recommended by the manufacturer. This is significantly longer than the service life of traditional coolants. It is made possible by the unique formulation of MS 90032 coolant. Because the coolant uses Organic Acid Technology (OAT) to provide extended engine protection.

On the other hand, MS 12106 coolant is a liquid coolant that requires mixing with water before use. According to the manufacturer’s recommendations, MS 12106 coolant should be changed every 150,000 miles or 5 years, whichever comes first. This is to ensure optimal engine protection. 

Winner: MS 90032 edges out the win but both coolant have very similar longevity. 


MS 90032 is a type of Mopar Antifreeze/Coolant that is a 10 Year/150,000 Mile Formula OAT coolant. It is the concentrated form of MS 12106, which is the pre-diluted form. 

It is an OAT (Organic Acid Technology) coolant. This means it is designed to have a longer service life than traditional coolants.

OAT coolant is more environmentally friendly than traditional coolants. OAT coolants use organic acids, which are biodegradable and less toxic than inorganic chemicals. This can help to reduce the environmental impact of coolant disposal.

Mopar Antifreeze/Coolant is a type of engine coolant manufactured by Mopar. It is the parts, service, and customer care organization within Fiat Chrysler Automobiles (FCA).

Mopar Antifreeze/Coolant is formulated with a combination of ethylene glycol and corrosion inhibitors. As it is an OAT Coolant, it contains organic corrosion inhibitors such as carboxylates and triazole

Winner: The first round is a draw because both of them have the same formulation with different concentration. 


MS 12106 coolant and MS 90032 coolant are two types of coolants used in different applications. But both coolants are designed to regulate the temperature of an engine, increase fuel efficiency, and improve performance.

MS 12106 coolant is a chemical solution used in automotive and industrial applications to regulate the temperature of an engine. It absorbs and removes heat from the engine’s cylinder walls, reducing drag on internal components and increasing fuel efficiency. 

By reducing drag, MS 12106 improves acceleration and top-speed performance. MS 12106 coolant also reduces carbon monoxide emissions, making it an environmentally friendly choice.

MS 90032 coolant, on the other hand, is a waterless coolant designed for power sports vehicles. Such as motorcycles, ATVs, and snowmobiles. 

MS 90032 is a specialized formula that eliminates the need for water. This creates a stable environment that prevents corrosion and bacterial growth. 

MS 90032 coolant is ideal for harsh conditions where servicing the cooling system can be difficult or impossible. It requires less maintenance than traditional coolant and helps to prolong the life of the engine.

MS 12106 and MS 90032 are interchangeable. They have no problem and will protect your car from extreme temperatures regardless of high or low they get.

Winner: This round is also a draw because both serve very similar purposes and they are interchangeable. 


The price of MS 90032 coolant is $22.5 per liter. And the price of MS 12106 coolant is $16 per liter. This is based on ATO 24 websites. 

It’s important to note that these prices may vary depending on the specific website or retailer you are purchasing from. As well as the quantity of the coolant you are purchasing.

Winner: MS 12106 wins this round because of its lower per liter price.

MS 12106


Both MS 12106 and MS 90032 are excellent options. You cannot go wrong with any of them as they are interchangeable and very similar in formulations. You just have to remember to mix water with MS 90032 prior to using it. 

You may consider MS 90032 in colder regions as it has a lower freezing point. But it is the more expensive option. The higher freezing point makes the MS 12106 a better choice for warmer climates. It is also more friendly to your wallet.  

Frequently Asked Questions (FAQs):

Why is antifreeze so colorful?

Antifreeze comes in different colors to help differentiate one kind from another. OAT coolant color ranges from pink, orange, bright red, red, blue and dark green. However, it is important to note that color is not a reliable predictor for what type of coolant you have

What Colour is OAT coolant?

OAT coolant comes in many different colors including green, blue, pink, and red. The color of antifreeze is generated completely by coloring dye, not as a direct result of any chemicals mixed during manufacturing. While specific colors agreed upon in the automotive industry do signify chemical makeup, variations still exist within each shade.

Are all OAT coolants the same?

No, not all OAT (Organic Acid Technology) coolants are the same. While OAT coolants share some common characteristics, such as their organic acid corrosion inhibitors, there are different formulations and types of OAT coolants.


And that concludes our discussion on ms 12106 vs ms 90032. They are coolant that can be interchanged, but they are different and are better with different types of vehicles. 

Our guide will provide you with all the information you need to make the decision. But know that you will not go wrong with any of them.
