Procedure
- 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.
For a BMW, what kind of coolant do I need?
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.
Where does BMW’s engine coolant go?
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.
Does my BMW require a special 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.
Can I use water in my BMW instead of 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.
Is water need to be added to 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.
BMW coolant is it pre-mixed?
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 does my BMW’s coolant gauge show low when it is full?
If the low coolant indicator on your dashboard illuminates, your car may be having one of the following problems:
- The most frequent reason for the coolant light on your car to come on is that the coolant is low. While it’s possible that the car is just short on coolant, it’s more likely that it has another problem that’s causing it to gradually lose coolant over time. You should have your car checked out and serviced if this is the case.
- Faulty Sensor: Your vehicle needs a sensor that measures the amount of coolant in its engine in order to know when the coolant level is low. When the coolant level drops too low, a floating sensor in the coolant reservoir of the majority of automobiles activates, putting on the warning light.
Your vehicle’s coolant sensor may be broken if you check your coolant reservoir and it looks to be full but your low coolant signal is on. The majority of auto repair businesses are able to identify and replace faulty sensors.
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.

Why does BMW have two tanks for coolant?
Low refers to the charge air (water cooled intercooler) system, whereas High refers to the engine cooling system. Your engine’s coolant system has to be topped out. The center-mounted one marked “low” is not equipped with a sensor to alert you when it is low.
Is BMW coolant leakage typical?
Your BMW might have one problem. Several issues, including a damaged radiator, a poor head gasket, or a frail radiator cap, might cause coolant leakage. You should contact a specialist as soon as you notice a coolant leak as this could cause very serious issues for your engine.
Can you combine blue and green coolant in a 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.
How is a low coolant level fixed?
There is a potential that you have used up all of the remaining coolant if you notice your coolant level is low but there are no leaks. The simplest way to fix low coolant is to start filling it back up to the proper levels and let it soak back into the system. The level of the coolant mixture currently in your tank is indicated by signs like “max” and “min” that you can see when you open your radiator cap. The low coolant problem should be resolved by simply filling the vehicle’s tank to an appropriate level (below the “max” line); nevertheless, continual monitoring for a week after filling is advised to make sure there is no coolant leak.
Do I have to wait to drive after adding coolant?
After adding coolant, how long should I let the engine run? The most crucial thing, he continues, is “your own safety.” The engine, hood, and any leaking coolant can all cool down by waiting for at least 15 minutes.
When my coolant level is low, can I drive?
Electric cars, hybrid cars, diesel engines, and gasoline engines all inherently produce heat. Some of this heat is directed into the interior of your automobile when you turn on the heater for comfort. However, there are other ways to control the majority of the heat.
Your car relies on a liquid known as antifreeze, sometimes known as engine coolant, to guarantee that the engine maintains an ideal working temperature. Driving with insufficient coolant could cause your engine to overheat, which is usually bad for your engine, your car, and your trip!
Can I replace coolant on my own?
Step back as the pressure releases, then slightly loosen the reservoir cover. The cap should then be fully removed. Add the proper coolant to the reservoir if the coolant level is low (not the radiator itself). Use diluted coolant alone or combine concentrated coolant and distilled water 50/50.
Are antifreeze and coolant the same thing?
Is coolant antifreeze? Engine coolant and antifreeze, however, are not the same. Before usage, antifreeze, a concentrated liquid with a glycol basis that must be diluted with water, is known as coolant. As an alternative, you can buy ready-to-use pre-mixed engine coolant, which is a mixture of antifreeze and water.
Antifreeze, which is mostly made of ethylene glycol, is used in a car’s cooling system to ensure that the engine can run without issue even in the coldest, subzero conditions. By reducing the freezing point of the coolant liquid inside your radiator, ethylene glycol also helps to lubricate the water pump and prevent corrosion.
Antifreeze and water are often blended in an engine coolant at a 50:50 ratio. This is due to the fact that antifreeze performs best when used as a diluted liquid (as a coolant) to battle extremely hot temperatures. All year long, the engine of your car may be successfully controlled to operate at the ideal temperature thanks to coolant in the cooling system.
Although antifreeze never goes bad, the chemicals that stop engine rust do. Therefore, it is advised that you replace your antifreeze in accordance with the manufacturer’s expiration recommendations.
Additionally, ethylene glycol is poisonous to both people and animals, so be sure to carefully heed the manufacturer’s safety recommendations and disposal guidelines.
What symptoms indicate low coolant?
After a while of driving, you get used to where your temperature gauge is when everything is in order. One of the most telling signs that anything is amiss with your cooling system is if it begins to lean toward red. If you see this while driving, stop, then lift the hood. By doing this, you’ll be able to start identifying the issue and help the engine cool.
