- 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 can I tell if the coolant in my BMW is low?
- Make sure to provide plenty of time for the engine to cool down and park your car on flat ground.
- Find the coolant reservoir by opening the hood.
- Turn the cap slowly in the other direction to release the extra pressure gradually.
- When the cap is taken off, a floating object will show up.
How do I determine the amount of engine coolant?
The first thing you should do if your coolant light turns on is to see if your levels are low. A hot pressurized liquid could spray out of your car if you don’t first let it cool down. Find the coolant reservoir underneath the hood, either on the front or side of the engine, and start there. It is often translucent with a “cold” and “hot” line labeled towards the bottom and top, respectively. Take off the cap to see if the levels fall below the “cold” line. If so, there is not enough combination.
A leak is typically to blame for low coolant. Hoses, gaskets, and seals on your automobiles tend to leak more as they get older. Finding and fixing a leak as soon as feasible is necessary.
What causes low BMW coolant?
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 can I tell if my coolant level is low?
The dashboard’s high-temperature gauge is one indicator of low coolant. You can use this gauge to detect when the engine is becoming too hot. The gauge should most of the time remain close to the intersection of the H and C symbols. Turn down your engine and have it towed to a Firestone Complete Auto Care in your area for repairs if the gauge is reading very close to the H.
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.
What sort of coolant is suitable for my 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.

The coolant light on my BMW is on why?
If the coolant light on your dashboard is on, you should safely pull over as soon as possible because this is a sure warning that your engine may be overheating. You run the danger of doing irreparable harm to your car if you opt to ignore the light.
Before checking the coolant levels after stopping, you should give your car at least 30 minutes to cool down. If you open your coolant reservoir too soon, hot, pressurized steam could shoot out and burn you if you don’t wait for your car to cool down.
Check the coolant reservoir beneath the hood of the car to see whether the fluid level is low after the engine has had time to cool down. If your coolant levels are low, you can carefully turn the cap to remove any trapped pressure before fully opening the coolant reservoir. Up until the reservoir is full, add coolant as necessary.
You should think about having your car towed to a repair facility if you personally discover any leaks. You can drive your car to a repair shop if there are no obvious leaks and the coolant light on the dashboard has stopped working. It is advised that you take your car in for an inspection and servicing as soon as possible, whether or not you can see a leak, to make sure it is safe to drive and to make sure any potential concerns are rectified before they create more issues.
Any problems that can prevent the right amount of coolant from traveling around your engine must be fixed because coolant is an essential component of your car while it is in operation. Your car will be serviced by qualified mechanics at My Euro Pro. Bring your vehicle to My Euro Pro in Wilmington, NC, Myrtle Beach, SC, or Charleston if you are having coolant-related problems and want to keep your BMW running smoothly.
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.
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.
When the automobile is hot or cold, do you check the coolant?
Locate the coolant reservoir by opening your hood after the engine has cooled. On the side of the coolant reservoir, there are F (full) and L (low) signs that indicate the coolant level. a
Heat is removed from the engine by coolant, which then disperses it into the atmosphere via a radiator. While coolant cycles through your cooling system again and again, it might evaporate and its level can gradually decrease over time. It is usually a good idea to check your coolant level frequently because coolant is essential for keeping your engine operating at the best temperatures.
A low coolant level in your coolant reservoir can cause overheating, and if your engine overheats, it could blow your water pump, head gasket, and cylinder head, among other significant damage. Look for any physical indications of coolant leakage once a week. Cars frequently experience coolant leakage difficulties as a result of defective radiator hoses or thermostat housing. It will substantially aid you in preventing overheating issues with your car.
The first thing you need to be aware of when checking your coolant level is that you shouldn’t do so when the engine is still hot. You should avoid touching the reservoir cap or radiator hoses until they have completely cooled down if your car has been running for a time because the engine, radiator, and reservoir all get quite hot. When an automobile is heated, it is under great pressure, making it risky to open the reservoir top. Hot coolant may shoot out of it if you attempt it while it is still hot, which could result in a severe burn. Therefore, always wait until the cooling system is cold before checking the coolant level.
Find the coolant reservoir after you’ve opened your hood. It is simple to locate the reservoir cap because coolant is written on it. Consult your owner’s manual if you still can’t identify it; it should describe its location. The ideal coolant for your car to prevent freezing and rust is also listed in the owner’s manual.
You can view your coolant level without opening the lid thanks to the L (low) and F (full) indicators on the side of the reservoir and the tank’s transparency. You need to top off the reservoir with more coolant if the fluid level is near or below the L sign. Again, before you do anything, check to see that the engine is cold and that there isn’t an excessive amount of pressure inside. Bring the level to F without filling it entirely.
Or, if the engine coolant warning light is illuminated on the dashboard, this might potentially mean that your coolant level is low or that your cooling system is malfunctioning and causing your car to overheat. If so, you can either check the coolant reservoir as previously described and add coolant to it, or if you’re unsure how to replenish the coolant, you can have it brought into an auto repair shop.
