- Hood is open. The hood release on your BMW 3-Series can be found underneath the dashboard. When you hear the BMW hood pop open, pull the lever. The hood safety latch at the front of your 3-Series needs to be released next.
- The hood should be raised and locked open.
- the Coolant Reservoir’s location. The BMW’s coolant reservoir (tank) can then be found. Here, you may check the coolant level and top it out if necessary. The coolant expansion tank is found on the driver’s side of the engine in a 3-Series. Slowly remove the cover. Only after the engine has cooled should you open the cap.
- Remove cap to check the coolant level in a BMW 3-Series. Observe the low and high levels in the coolant reservoir tank. You must replenish coolant if the level falls below the minimal level, or your 3-Series risked overheating. The floating gadget is used by the BMW 3-series to gauge the coolant level.
- Add antifreeze and engine coolant. Use only the BMW-recommended coolant type.

How much coolant should you use in a 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.

Is it possible to add coolant to a BMW?
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.
In a BMW, where is the coolant located?
Find the coolant reservoir by opening the hood. This tiny black tank is typically located to the left of the engine in BMW models, but it isn’t always the case. If you’re unsure of what to look for, double-check your owner’s manual. Turn the cap slowly counterclockwise to gradually remove the extra pressure.
What occurs if the incorrect coolant 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.
Should I mix BMW coolant?
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 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
How much does a BMW coolant change cost?
$188 for a BMW Coolant Flush and Pressure Test To guarantee that your engine is properly ventilated for the upcoming drives, your coolant flush service will remove dirt, rust, the water pump, and engine passages.
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.
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.
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.
BMW coolant is what color?
To maintain your cooling system operating at its peak, we advise using only German OEM BMW engine antifreeze, part number 83192468442. (83 19 2 468 442). 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 (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.

Can I simply top off my car’s coolant?
Add the proper coolant to the reservoir if the coolant level is low (not the radiator itself). Either diluted coolant alone or a 50/50 blend of concentrated coolant and purified water are acceptable. Replace the cap and tighten it until you hear a click when the coolant reaches the cold fill line. Shut the hood.
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.
How long can you keep your coolant low?
How long can an engine run without coolant? is a question we hear a lot. Maybe answering this issue will be simpler now that you are aware of how crucial radiator coolant is. It is dangerous to drive a car with low or no engine coolant since it could harm some of the engine’s secondary and even primary components. It is preferable to stop if there is insufficient coolant in the vehicle. Even a brief drive in such a vehicle is not recommended because it could seriously harm the engine of your vehicle and incur expensive repairs.
Many new and modern automobile brands have a cut-off feature that checks the engine temperature and detects a lack of coolant. This detection feature turns off the car engine to guard against potential engine damage if there is a shortage of coolant in the cooling system of the car and, as a result, a perception of a significant increase in engine temperature.
However, if you drive an older vehicle, you must be aware of the symptoms of a coolant shortage to save your engines from overheating, seizing, or bursting a gasket. The following is a list of some of the most frequent cooling system parts that sustain the most harm when the cooling system overheats and runs out of coolant:
- water meter
- head seals
- engine timing for the cylinders and pistons
- piston head
- twisted or warped connection rods
- Lack of a crank
Repairing or replacing these parts is quite pricey. Therefore, try to avoid allowing your car’s cooling system to overheat due to a shortage of coolant.
How far can a car be driven without coolant, then? You can continue driving for a while if your car’s coolant level is low. Really, it depends on the coolant level. You can drive your car for a few days if it is low but still higher than the required amount. However, if the level is below the minimum, kindly do not even attempt to start your engine.
