The Top Five Coolants for Your BMW
The cost of a BMW is high. Investment is made in them. Additionally, an investment needs lots of TLC and cautious maintenance. One of the cheapest and simplest ways to keep your Beemer in peak condition is to make sure you use the appropriate brand of coolant. Coolant is a mini-miracle worker because it prevents rust, serves as anti-freeze in the winter, and helps with engine cooling in the summer. It’s a must for all cars, including BMWs. However, a BMW isn’t your ‘average’ automobile, and it has slightly different coolant requirements than you might be accustomed to. In addition to a long list of other requirements, beemers require coolants that are free of nitrates and phosphates and that prevent the corrosion of aluminum components, making the task of selecting the appropriate one much more difficult than you may expect. However, keep calm. You’ve come to the correct place if reading the fine print on the back of coolants is keeping you from having fun. We’ve read the reviews, combed through the research, and scrutinized the labeling. We discovered the top five BMW antifreeze varieties while doing this. Here they are without further ado.
Which Coolant is Best for My German Car?
No matter what type of car you drive, whether it’s a BMW, Porsche, Mercedes Benz, Audi, Mini, or Volkswagen, your car circulates a solution of water and coolant to dissipate the heat generated within the engine and prevent it from completely melting down (one notable exception are older Porsche models that are air and oil cooled and did not use water or coolant, but instead circulated a large amount of oil to dissipate the heat).
A Spectrum of Colors
Which coolant type is best for your BMW, Porsche, Mercedes Benz, Audi, or Volkswagen out of the many available options? The answer is the kind that was initially installed in your car. Your coolant may be green, pink, blue, yellow, or even clear depending on the manufacturer. All coolants are naturally transparent, and dye is used to give them color. It has no impact on the coolant’s chemical properties that each producer adds their own colour blend. Because the water in Europe is substantially harder than the water in the United States, European manufacturers prefer coolant that is phosphate-free.
Inorganic Acid Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology (HOAT) are the three most common coolant types available today. A HOAT coolant is used by your BMW, Porsche, Mercedes Benz, Audi, or Volkswagen.
In order to protect aluminum surfaces, silicate is added to OAT coolants to create HOAT coolants. The cylinder heads and radiators, as well as other parts of your BMW, Mercedes Benz, Porsche, Audi, and Volkswagen engine and cooling systems, are constructed of aluminum.
Silicate and phosphate corrosion inhibitors are not used in OAT coolants. These coolants are made to last for 150,000 miles and have a long service life (or 5 years). It should be mentioned, nevertheless, that German Auto Center and the majority of manufacturers advise cleansing or replacing the coolant every two years.
The metal (Iron) components of the engine and cooling system are protected by traditional coolants, which are IAT coolants and use silicate and phosphate corrosion inhibitors. IAT coolants shouldn’t be utilized because the majority of the iron components in your BMW, Mercedes Benz, Porsche, Mini, Audi, and Volkswagen have been replaced with aluminum and other lighter composites.
It’s crucial to keep in mind that modern German performance cars, whether you drive a Porsche, Mercedes Benz, Mini BMW, Volkswagen, or Audi, will last you for many miles and years if you maintain them properly.

Does BMW require a particular coolant?
In addition to controlling engine temperatures, the quality of your BMW coolant is essential for lubricating the water pump, guarding against corrosion and buildup, providing anti-freeze during the winter, and, in some models, assisting in cooling for engine and gearbox oil coolers. Not just any antifreeze will do; BMWs have special coolant needs (nitrite and phosphate free) to prevent build-up and corrosion of metal components. Along with BMW coolant, we also sell coolant additives like Red Line Water Wetter, which lower combustion chamber temperatures and elevate boiling points in order to prevent detonation and banging.
Why is the coolant in my BMW low?
You should take your automobile to the automotive service shop as soon as possible for an inspection and maintenance if your coolant is low because it could be an indication of a larger issue. Some of the causes of a possible coolant shortage in your car include the following:
- reservoir leak or overflow tank
- a radiator leak
- radiator hose leak
- water pump leak
- cracked or compromised radiator seal
- defective head gasket
Will Prestone coolant work in a BMW?
Yes. OAT coolant/antifreeze Prestone also has anti-corrosion components to safeguard your cooling system. It works well in all vehicles, provides the same levels of security, and causes no harm.
How often is coolant required for a BMW?
Typically, every 30,000 miles or every two years, you should have a BMW coolant cleanse conducted. Your car may be able to go longer between flushes in specific circumstances.
Do I need to combine water and coolant for a BMW?
Keep your cooling system operating at its peak performance by using BMW engine coolant (antifreeze). This 1-liter bottle works well for little top-offs of coolant that has been lost. For the best defense against boiling, freezing, corrosion, and lubrication, coolant is mixed with distilled water. For the optimum protection in street cars, mix distilled water with antifreeze 1:1. Reduce the amount of antifreeze in your coolant mixture if you want more cooling properties, but only in warm climates where freezing is not an issue. We advise monitoring the freezing point of the coolant mixture if you want to use antifreeze and water ratios other than 1:1.
Red Line Water Wetter can also be used with pre-ignition if high temperatures could lead to engine knocking.

Why is blue coolant used by BMW?
The majority of coolant manufacturers in East Texas, where we can experience a wide variety of temperature variations throughout the year, offer an engine coolant that is a 50/50 combination.
In order to receive the greatest cooling benefits for our Texas climate, BMW “Blue Coolant” must be mixed and added to your cooling system in the right manner. This calls for a coolant flush and refill procedure that removes air and old coolant from your system to improve engine safety.
Because it is silicate and phosphate free and has a far longer lifespan inside of your car’s cooling system, we advise using BMW “Blue” coolant in your vehicle.

Can I use water in my BMW instead of coolant?
Your radiator system becomes more contaminated when you use water. Although using water instead of low coolant is significantly better for the engine, you should switch the water out as soon as you can for the proper coolant for your car.
Any remaining coolant in the radiator is diluted when water is added to it. Preventing corrosion, raising the boiling point of water, and reducing the freezing point of water are just a few of the crucial jobs that coolant does. While using water in place of the coolant will allow you to drive the automobile for a brief period of time, your engine won’t be adequately protected.
This means that the radiator needs to be filled with a 50/50 mixture of coolant and water as soon as the issue that led to a low coolant level is resolved.
Can you combine blue and green coolant in a BMW?
It appears that they can coexist, with green being able to mix with blue-filled cars but not the other way around. from getbmwparts copied: G48 coolant (blue) should not be used in vehicles that were first filled with HT-12, although BMW HT-12 can be used in any vehicle that now uses G48.
What occurs if the incorrect antifreeze is used in a BMW?
The performance of the car can be hampered if the wrong coolant is used or if several types are mixed together. Additionally, the radiator’s corrosion may worsen. It’s crucial to remember that color alone cannot accurately identify the type of coolant you should use. The radiator, water pump, radiator hoses, cylinder gasket, and other components can suffer corrosion and other issues as a result of using the incorrect coolant. Having a qualified auto mechanic handle your vehicle’s maintenance is the greatest method to guarantee that you obtain the right coolant.
