Can I Mix Blue And Green Coolant BMW?

It appears that they can coexist, with green being able to mix with blue-filled cars but not the other way around. HT-12 can be utilized in any car that currently has G48 coolant (blue), but G48 shouldn’t be used in cars that were filled with HT-12 initially. This information was copied from


Once combined, 1 gallon of Genuine BMW coolant will yield 2 gallons. Since you already require about 2 liters…

The item is incompatible with your BMW!

To maintain your cooling system operating at its peak, we advise using only German OEM BMW engine antifreeze, part number 83192468442. Because they don’t include nitrites, amines, phosphates, or borates, BMW exclusively suggests specific coolants. It is not permitted to use store-bought coolant from a nearby parts retailer.

2018 saw the introduction of this new green coolant, which has replaced the previous blue coolant. Green can be used on automobiles before 2018 and is backwards compatible with blue. BMW advises against using the older blue formula on vehicles created after January 2018.

The silicates in the green coolant provide further protection for the cooling system’s internals, although the coolant needs to be changed every two years.

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. 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.

Can I mix 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 green and blue coolant be combined?

Let’s address the big question: Can you combine different brands? now that I’ve clarified what goes into coolants.

Yes, that is the response. Peak can be blended with Zerek or Prestone, but only if they are both the same chemical type of coolant. The ratio is less important, but the type and application must be compatible.

The simplest method to keep this in mind is to try to pair together like types: IAG with IAG, OAG with OAG, and HOAT with HOAT.

However, it’s qualified and depends on getting things to match as closely as you can, just like anything else. Combining various antifreeze or coolant brands may reduce their corrosive effects and endanger your engine.

There will be times when you won’t have an option but to use various coolant or antifreeze brands. as when you go to a hardware store or gas station and discover that the brand you typically buy is sold out.

The safest course of action in that case is to drain the old coolant and replace it with the safest coolant or antifreeze you can locate.

In a pinch, however, you can use the closest match, particularly if it’s temporary.

I have a BMW; may I use green coolant?

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.

How is BMW coolant blended?

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.

Can you mix different coolant colors?

Mixing two distinct antifreeze colors or types is never a smart idea. While combining two recipes won’t result in any explosive or harmful reactions, it may cause your coolant to become a sluggish chemical brew that won’t be able to pass through your cooling system as intended. In order to function properly, coolant must be fluid, and a thick coolant could block the cooling systems and cause other potential problems in the engine of your car. The final word? Don’t combine antifreeze in different colors.

Is blue BMW coolant required?

It doesn’t have to be blue, though. I use Zerex G-05, and the independent BMW shop next to me does also for all the vehicles. BMW coolant is made of ethylene glycol and is phosphate and nitrate free. It’s fine as long as you buy coolant that meets those requirements.

What shade of coolant does a BMW require?

What shade of coolant is used in the BMW 325i? It’s wonderful to realize that color is irrelevant. Hybrid Organic Acid Technology (HOAT) coolants are orange and yellow, as opposed to the typical orange, yellow, red, or purple of Organic Acid Technology (OAT) coolants.

Which coolant is OK for my BMW?

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.

Does BMW require a particular coolant?

Antifreeze and coolant Any generic antifreeze won’t work since BMWs have unique coolant specifications (nitrite and phosphate free) to prevent build-up and corrosion of metal components.

Is blue coolant superior to green coolant?

There really isn’t much of a difference in terms of performance benefits because both coolants will function equally well in your Nissan. Nissan Green is likely what we would choose because it is concentrated (making it slightly less expensive) and because we believe that changing the coolant more frequently is preferable for preventative maintenance.

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.

What is coolant in blue?

The only possible meaning of a blue engine coolant temperature signal is that your coolant, or antifreeze, is too cold. In fact, the temperature is so low that your radiator could become too cold, which would prevent your engine from starting since it would freeze up.

What is the price of BMW coolant?

A BMW 328i coolant change typically costs between $276 and $315. While materials are priced at $124, labor costs are projected to range from $151 to $191.

How long is a mixed coolant vehicle safe to operate?

Chemical bonds between organic and inorganic materials make up hybrid coolant. A hybrid coolant typically contains silicates, nitrites, oxygen, and glycol as its chemical constituents. These substances boost a car’s gas emissions while enhancing engine efficiency.

Coolants cannot be mixed on your own. Physical mixing is just mixing two coolants together, whereas chemical mixing involves combining the right minerals in a closed environment.

However, hybrid coolants enable you to travel 30,000 miles or more in total. This distance is merely a guess. It still depends on how often you use the automobile and how well the engine is maintained.

Because healthy gas emissions are combined with engine performance efficiency, most auto owners favor hybrid coolants.

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

What occurs if the incorrect antifreeze is used in a BMW?

The performance of the specific additive packages can be hampered by mixing various engine coolants or by using the incorrect coolant, which can lead to increased corrosion of the radiator. The engine coolant needs to be changed more frequently as the cooling system’s protective layers gradually get thinner and more porous. Using the incorrect engine coolant can progressively cause corrosion and damage to the cylinder gasket, water pump, radiator, and radiator hoses. In the worst situation, this may result in engine damage.

How often should I change the coolant in my BMW?

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.

Can I substitute water for coolant?

Due to its narrow range of boiling and freezing points and inability to safeguard the engine of your car, water cannot substitute for antifreeze on its own. Additionally, it doesn’t absorb heat as well. You can use water in your coolant rank in a severe situation.

Is antifreeze the same as coolant?

Antifreeze, commonly referred to as engine coolant, is combined with water to prevent the radiator from freezing in extremely cold weather and overheating in extremely hot weather. Knowing which coolant type is best for your automobile or truck is crucial because there are numerous varieties available.
