Since it is summer, I would simply top off with water (up to max line only, when engine cold). Then watch it closely. If you suspect a leak, go to the dealer right away.
Water topping up is acceptable, but since the coolant system is sealed, it shouldn’t need to be done.
Keep an eye on the coolant level and let your dealer know if you see any loss as this is a common sign of a damaged EGR cooler.
Is there any sign of sooting on the insulation beneath the underside of the EGR cooler? Another indication of a damaged EGR cooler is that.
Mine has experienced this twice in the recent days. I simply added water to top it off. I’m hoping it doesn’t get worse before my duty the following week.

2 liters of BMW coolant cost around PS11, I believe. For the ideal blend ratio, combine it 50/50 with water.
If you can’t see it, use a torch to illuminate it. Fill the container when it’s cold so the water or coolant just touches the mark.
FFS, do it in a cold car. If you attempt to remove the cap before it is entirely cold, you risk burning yourself.
Don’t top off with tap water; instead, use that RO water product (I can’t recall its name, but I’m sure someone will confirm). can purchase it in bottles at the grocery store.
Tap water causes that corrosion-causing green substance (sorry, I’m useless; it’s been so long since I’ve had to top any car up).
A damaged EGR housing is what’s causing my low coolant signal. Due to BMW’s lack of inventory in the UK, this item will arrive from Germany the following week.

How is the coolant refilled in a BMW?
I normally have my technician add more coolant to my BMW when I get my car serviced, but there doesn’t seem to be anything else wrong with my car. I’m not interested in taking the car in to obtain more coolant. Is there a way for me to refill the coolant on my own?
In less than two minutes, find out if your auto insurance is being overcharged.
Your car’s coolant can be filled on your own, yes. You will require the following supplies to refill the coolant in your BMW:
- according to the instructions in your manual, a fresh bottle of coolant
- the funnel
- One set of gloves
To top off the coolant in your BMW, complete the following steps after gathering the necessary materials:
- Identify the coolant tank by opening the hood. If your automobile is hot and you just switched it off, don’t touch anything there.
- While pressing downward, rotate the cap in the other direction.
- When the cap is removed, a brightly colored stick or level float ought should be visible. If the coolant tank is properly filled, a schematic showing the level float’s location will be located anywhere on the tank.
- Place the funnel in the tank, leaving enough room for the level float to be visible.
- Until the float reaches the appropriate height as shown by the diagram, begin adding coolant.
- Replace the cap after carefully removing the funnel.

The best coolant for a BMW is what?
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.
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
My BMW has no coolant, can I add some?
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 add more coolant on my own?
It’s easy to top off the coolant in your engine by opening the reservoir cap; just make sure the engine isn’t running too hot and open the cap with a cloth wrapped around it in case there’s any trapped pressure. What you use to do this, though, is crucial.
- Use a quality engine coolant that you can purchase at an autocenter or local dealer. Simply adding water is not advised since any minute organisms or impurities could accumulate inside your engine and cause the coolant pipes to ‘fur’ up, thereby obstructing the internal waterways. If that’s all you have, it’s still preferable to use ordinary water rather than letting your coolant level get too low.
- Using distilled water instead of store-bought coolant is an option. Since this has been cleaned, it is free of the impurities that can harm your pipes.
Do BMWs require specialized 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.
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 (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.

Can water be used in a BMW as 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.
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 does a BMW’s coolant light appear?
To keep your engine from overheating, coolant fluid absorbs the heat from your engine and distributes it through the radiator.
When coolant levels are low, this yellow warning light will illuminate to prompt you to top them off.
Avoid taking any lengthy trips without enough coolant; instead, stop as soon as you can and top it off to prevent major damage to your vehicle. Before topping off, let the engine to cool. Get your car serviced if this light appears frequently to be sure there isn’t a leak.
Can a BMW be operated with the coolant light on?
It can startle you when the coolant light on your BMW illuminates. Any sign that your BMW isn’t operating properly should raise suspicions. If this occurs to you, you should immediately pull over and stop driving even though this normally indicates that the coolant level has fallen too low. Refilling your coolant could be a simple remedy, or you might need professional assistance to fix your BMW.
Is it acceptable to add water to coolant?
Only in an emergency situation when the coolant liquid level is lower than it should be, should coolant be topped off with water.
You shouldn’t rely on topping up with water to bring you safely to the closest garage and help you find any problems.
A small amount of water added to coolant shouldn’t cause any significant harm, but too much water will lower the coolant’s boiling point and prevent it from performing as effectively.
