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.

Step 4: Replace the coolant in the BMW’s cooling system.
Before filling the system once more, make sure that all of the drain plugs are secured. We want to achieve a 50/50 blend of distilled water and antifreeze. Check to see if the water and antifreeze have already been blended. If it was, just pour the water in without adding more. If it wasn’t, choose a 50/50 mixture.
Pour in 5 liters of water and 5 liters of antifreeze if your car used 10 liters of water (2.64 gallons) during the water flush. You would need to remove the blender screw if your car has one; otherwise, just add coolant.

As previously stated, distilled water must be used to dilute the BMW blue coolant. Don’t believe the person who answered the phone; believe the instructions on the product itself (and everyone else here).
4. Combine one part BMW Antifreeze with one part water for the optimum all-year protection and performance. Corrosion and freezing protection are provided by this 50/50 combination down to -34°F. The mixture can be raised to a ratio of 60% antifreeze/40% water during the winter in severely cold places, which gives freezing protection down to -62degF. Never go above a 60% antifreeze percentage.
Ratio of a Coolant Mixture
The standard ratio for coolant to distilled water that is advised is 40/60. In order to have a stronger endurance for freezing temperatures, one can alternatively use a 50/50 mixing ratio.
If one utilized coolant and water in a 60/40 ratio, what, if anything, would happen? Would this affect the mixture’s ability to cool?
Both ratios are provided in my BMW Motorrad K-Models Repair Manual. 50/50 blend for antifreeze down to -36 degrees Celsius and 60/40 water down to -28 degrees Celsius.
According to my understanding, larger concentrations have a poorer potential for heat transmission than lower ones. Therefore, the 60/40 would be superior in that sense and possibly better for settings with greater temperatures.
I’m not sure if I agree with your findings, which are in bold and italics. You mean more antifreeze than water, like 65/35 or 70/30 antifreeze/water, when you say higher concentration?
How can the higher, less heat-dissipating combinations be better in hotter regions if they have a lesser capacity to dissipate heat than the lower ones?
If my memory serves me right, although it could not, water can transfer a certain number of BTUs of heat while antifreeze can do so at a lower rate per unit of time. If water can transfer, for example, 10% more BTUs of heat than antifreeze, you start to lose more and more of that 10% advantage as the water ratio in the mixture decreases.
Higher ambient temperatures in hotter climes call for greater heat transfer from the engine. However, there is a cost because you also need protection from boil overs, which antifreeze offers in addition to freeze protection.
BTUs don’t require numbers as long as the description is clear.
And I think you made a valid point.
Can coolant and BMW coolant be mixed?
Yes, you must drain it right away and rinse it out completely with distilled water. Dexcool utilizes OAT antifreeze while BMW uses HOAT. They might or might not get along, but it’s not a chance you should take.
Is it necessary to combine water and BMW coolant?
To make the best coolant, they must be mixed. You can purchase antifreeze that is full strength and needs to be diluted with distilled water before being applied to the engine system, or you can purchase ready-made combinations of coolant that already have water added.
Can I use blue and green coolant in my 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.
Is it possible to add coolant to a 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.
What happens if I fill my BMW with the wrong coolant?
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.
How is coolant handled by BMW?
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.
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. 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.

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.
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 any blue coolant work in a BMW?
Now they can all work together. Ethylene Glycol serves as the “Active Ingredient” in “BMW” Coolant in addition to distilled water. Also concur with the distilled water
What is the ideal coolant composition?
The cooling liquid in the cooling system is referred to as coolant in general. Coolant lubricates while offering protection from overheating, corrosion, and freezing. Its job is to take the heat from the engine and release it through the cooler.
The anti-freezing chemical (glycol/ethanol) and tap water are combined to make the coolant, which is also colored and contains a number of additives (bitter substance, silicate, antioxidants, and foam inhibitors). In order to stop the coolant from accidentally being drunk, bitter chemicals are employed. Silicates create a barrier of defense on the metal surfaces, preventing things like limescale buildup. Antioxidant substances stop components from corroding. Foam inhibitors prevent the coolant from foaming. Glycol boosts the boiling point of the coolant while maintaining smooth hoses and seals.
Water and antifreeze should be combined at a 60:40 to 50:50 ratio. This typically equates to antifreeze protection between -25 and -40 degrees Celsius. The ideal mixing ratio is 40:60, and the ideal minimum is 70:30. The freezing point does not decrease any further when the antifreeze content is increased (for example, to 30:70). On the other hand, undiluted antifreeze freezes at about -13 degrees Celsius and does not sufficiently dissipate engine heat at temperatures higher than 0 degrees Celsius. The engine would get too warm. Glycol has a very high boiling point, thus by utilizing the proper mixing ratio, the coolant’s boiling point can be increased to as high as 135 degrees Celsius. Therefore, even in warm areas, having a suitable antifreeze share is crucial. Always adhere to the manufacturer’s guidelines. Using inhibited water, a typical composition can be 40%/60% or 50%/50%.
The coolant and its additives are subject to some wear, meaning that over the course of a few years, some of the additives will be consumed. The coolant turns brown, for instance, when the corrosion prevention chemicals are depleted. As a result, some manufacturers provide an interval for changing the coolant.
However, so-called long-life coolants (such VW G12++ / G13) are increasingly used in the cooling systems of contemporary automobiles. The coolant does not need to be changed under normal conditions (assuming contamination does not occur) or only after 15 years or 250,000 kilometers (VW). As a general rule, vehicles without long-life coolant should have the coolant changed if contamination (oil, corrosion) has taken place. The guidelines provided by the vehicle’s manufacturer must be followed with regard to the antifreeze’s specs, replacement period, mixing ratio, and miscibility.
Coolant must not be discharged through the oil separator or into the groundwater. The removal and disposal of coolant must be done separately.
