- 3 Conclusion
You know that your car’s engine is in tip-top condition by having the best coolant. This is a very important part of the entire cooling system of the engine, and is ideally a 50:50 mixture of antifreeze and clean water. Coolant or antifreeze greatly helps in keeping the engine from freezing up during the winter season and during cold weather conditions. On the contrary, it helps in keeping the car cool during the summer season.
When mixed with water, coolant is placed in the reservoir and radiator of the car, adding more coolant between certain intervals, such as between mechanic visits. The flushing and filling of fresh coolant are necessary every 2 to 5 years, depending on the coolant type you use. Some manufacturers formulate and add some ingredients for rust and corrosion protection.
However, these ingredients break down over time, becoming harmful to your engine; thereby, requiring you to flush the entire system. With this regard, you will need the best antifreeze in keeping your engine’s cooling system in an excellent condition for as long as you need it to.

Coolant / Antifreeze Buying Guide
After learning about the top-rated coolants on the market, it is now time to learn about the engine coolant types, including some important tips and other essential information involving this product.
Basic Types of Coolants/Antifreeze
Choosing between the coolant types is a crucial step throughout the process. You should understand that there are three basic types on the market, each formulation differ from one another as one type offers slightly different benefits over the others.
While a vehicle can run with any type of coolant, it is important to use the most appropriate variety, which may be affected by different factors like the kind of additive antifreeze offers for better metal protection. In line with this, below are the basic types of coolant, allowing you to differentiate one over the other.
- Inorganic Acid Technology – Also referred to as IAT, this among the antifreeze types, which is widely used in the US-manufactured vehicles, dating from the 1920s up to the late 1990s. Naturally, this coolant is clear, but dyed green for identification. IAT coolants contain phosphate and silicate corrosion inhibitors for metal parts protection as it runs through the radiator and the engine. The experts highly recommend that this green antifreeze, be flushed out once in a two-year interval or every 30,000 miles. It is also recommended for Chrysler, Ford and GM vehicles.
- Organic Acid Technology – Known as OAT, this type is available in different dyed colors, ranging from dark green to orange. Compared to IAT coolants, OAT coolants do not contain phosphates or silicates; thereby, it has higher chances of lasting much longer than IAT coolants. However, it can wear down some metal parts in the engine and radiator eventually. Fortunately, manufacturers have engineered OAT coolants with additives that promote rust and corrosion protection. It lasts for 150,000 miles or five years. The orange antifreeze is dedicated to GM vehicles, while the pink to VW, green to Honda, and red to Toyota vehicles.
- Hybrid Organic Acid Technology – The HOAT coolants are similarly available in varied colors or dyes like orange and yellow. This type of antifreeze contains some silicates for corrosion reduction, and some additives for rust and corrosion prevention. Like the OAT, the HOAT must be flushed out every 150,000 miles or 5 years. It is recommended to use for Chrysler, and major European car makers, German, and Asian.
Determining What Coolant to Use
Determining what kind of antifreeze you need to use, largely depends on the manufacturer of your vehicle. Every car manufacturer often makes use of a single product line of coolant in all their vehicles. By following this tip, you can immediately identify the proper coolant to buy for your car. Comparing the coolant colors for each car make also helps solve your predicament. For instance, the pink antifreeze will be the most appropriate for your VW vehicle.
Another way to identify what coolant to use is by referring to your car’s manual. If the owner manual is unavailable, you can always search through the manufacturer’s website. And, if else fails, you can ask a reliable mechanic for wise suggestions and recommendations.
Many drivers still find it a mystery in determining the main difference between coolants, like that with the engine oils. At the best of people’s knowledge, knowing what is in the red antifreeze may not be available in the blue or pink, is less than what really needs to be understood. Without getting too much ‘geeky,’ however, here are some fundamental things every probable coolant user must know.
- Color Is Not Equivalent to the Type – Mixing colors and types can certainly cause failure, although the results may not appear immediately. By doing such, your engine and cooling system will not function well as the coolant can turn into gel gradually, thus, it restricts flow. Keep in mind that the standard green coolant has additives, especially geared towards corrosion prevention on steel parts, while others are specifically designed for aluminum and alloys.
- Stick to the Ratio – There are some types of engine coolant that allows a direct use, straight from its container. But, there are others, which require a 50-50 ratio, whereas the other half is clean water. A too weak or too strong mixture results in poor engine cooling.
- Always Keep Water in the Trunk – Water is always better than nothing, especially if there are no repair facilities or gas stations when your vehicle runs low on coolant. In such cases, adding water to your cooling system may be enough until you get hold of more coolant.
Adding More Coolant
By now, you should be certain on what type of antifreeze to use, although there are no specific and immediate dangers to mixing coolants in your car. But, once you add an HOAT or OAT coolant to an IAT, the HOAT or OAT coolant will lapse to a two-year service life like that of the IAT coolant. Some experts also believe that combining coolants in a radiator may result in coolant gelling under certain circumstances.
Adding more coolant to your vehicle in between visits to the mechanic and allowing the coolant system flushed out, is a very wise idea to keep your vehicle running well, regardless extreme weather conditions. Otherwise, you can complete the entire process by yourself as this may also be a do-it-yourself job, provided that you have the proper coolant, safety glasses, work gloves, a flashlight, and a funnel. You can likewise refer to the instructions provided by the product.
Over and above, car manufacturers make use of one type among the car coolant types. It is highly recommended that you use the same type, which already exists in your car. Your owner’s manual comes in handy when determining the correct coolant type, while the coolant color can possibly identify the proper type as well.
As discussed above, antifreeze compatibility is fundamental to prevent unwanted damages over time, sticking to recommendations all the time will never give you harm. Nevertheless, radiator coolant is as essential as engine oils and brake fluids in keeping your car in top-top condition.
