For BMW vehicles, the ZEREX G-48 coolant is perfect. The coolant, which is made for both diesel and gasoline engines, contains low-silicate, pH, anti-phosphate technology that guards against corrosion in all metals, including aluminum.
It is diluted at a 1:1 ratio to protect the modern engine’s components from freezing in the winter and boiling over in the summer. Additionally, the combination is prepared in 5:7 ratios for maximum protection. It also includes a high-quality defoamer system and contains less silicon than the vehicle’s mandated 250 parts per million.

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.

What kind of antifreeze should I use, BMW?
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.
Is Prestone antifreeze safe to put in my 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.
Which antifreeze is best for my car?
You’ll need to discover the appropriate coolant when it’s time to top off or do a full system flush. If every manufacturer used the same coolant, it would be convenient, but they don’t. Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), and Hybrid Organic Acid Technology are the three primary forms of coolant that automakers utilize (HOAT).
Most vintage vehicles employ IAT. It is far less effective than more recent formulae and must be replaced every two years or 24,000 miles. OAT is one of those more recent mixtures. This formula is used in General Motors vehicles, which typically need to be changed after five years or 50,000 miles. Finally, HOAT is a derivative of OAT and, unless otherwise specified, requires the same time change interval.
Visit your car’s dealership to ensure you’re buying the appropriate coolant for the task. Your precise make and model’s recommended coolant will be sold, and it will be the right one. The coolant is frequently marked with the name of the vehicle it will be used in.
For instance, all of Honda’s dealers sell Type 2 antifreeze/coolant. Many others, like BMW and Volkswagen, operate in a similar manner.
Though not all manufacturers do this. All GM vehicles come equipped with a system called Dex-Cool. Ford utilizes Motorcraft in contrast.
You should be aware that almost every current coolant jug you come across has already been diluted. In the past, coolant was usually sold as pure coolant, which required manual water dilution. Of course, the pre-diluted product is more practical, but you wind up spending much more for less coolant.
How long does antifreeze from a BMW last?
How frequently should a BMW have its coolant changed? 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.
What is the price of BMW coolant?
Coolant leak repairs can be very expensive. Fixing this is expensive because it is a laborious operation. The price of BMW coolant repairs varies depending on a number of factors, but it typically ranges from $750 to $1,000. Although the parts themselves are not very expensive, the labor required by mechanics means that they may charge more for this kind of repair. The type of damage and the specific fixes the mechanic needs to do determine the costs of these repairs. You can be given a few alternative solutions for resolving your BMW coolant leaks by them.
Every option has pros and cons, so you should consider them all carefully before selecting one. Prior to selecting a mechanic, you should always collect various bids. Every repair shop will impose a different fee. If it does, it’s critical to decide which solutions are best for you and your circumstances.
They will be able to assist you during the entire decision-making process because you are working with reputable automotive shops. Since this is a significant purchase, you want the greatest possible workout for the money you are spending, thus you want someone to assist you.
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
Why is blue coolant used by BMW?
To maintain your cooling system operating at its peak, use only German OEM engine antifreeze, component number 82141467704. (82 14 1 467 704). Because they don’t include nitrites, amines, phosphates, or borates, BMW exclusively suggests specific coolants. BMW cooling systems typically do not work with off-the-shelf coolant from a neighborhood parts store, and mixing various coolant formulas is not advised (in a pinch you should use distilled water).
The well-known blue coolant, which has been in use since the 1990s, is only permitted for vehicles with model years up to 2018. Internally, it is referred to as the G48 formula and is exclusive to BMW/MINI vehicles. In comparison to other forms of coolant, the blue coolant formula is a hybrid that extends coolant service life and is less harmful to the environment. On vehicles manufactured in 2018 and later, BMW replaced it with a new formulation that contains silicate and offers superior immediate corrosion protection. BMW does not advise using the older blue formula for vehicles created after January 2018.
For increased corrosion resistance, anti-freeze defense, and water pump lubrication in street cars, we advise combining distilled water in a 1:1 ratio with the mixture. Reduce the amount of antifreeze in your coolant mixture if you want more cooling properties, but only in warmer climates where freezing is impossible (see chart below). 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 added if high temperatures could lead to engine banging or pre-ignition.

- optimum cooling, freeze prevention, lubrication of the water pump, and corrosion resistance
BMW coolant is either blue or green.
I recently learnt that BMW no longer uses blue coolant, only green, but I already have blue coolant specifically manufactured for BMW.
Can the incorrect antifreeze cause an overheat?
Your coolant has a problem. If the incorrect coolant was used in your vehicle or you have an unsuitable coolant-to-water ratio (50/50 is ideal), your engine may be more susceptible to overheating.
What do the various antifreeze colors indicate?
Healthy engine coolant is either green (for ethylene glycol) or orange in hue (for Dexcool). A rusty tint means the coolant’s rust inhibitor has degraded and is no longer able to prevent the accumulation of rust and scale. To restore integrity, the system needs to be cleaned/flushed and a new 50/50 coolant mixture installed.
When the hue is milky, there is oil in the system. This is bad news since it typically indicates that the engine coolant is being contaminated with oil or transmission fluid due to a failing head gasket, intake manifold, or transmission oil cooler. This lethal combination will quickly destroy an engine or transmission. Deal with the issue right now!
