In BMW vehicles, the coolant warning light is located on the instrument panel, and it is used to indicate a low coolant level. The coolant is a vital part of the BMW’s cooling system, and it helps to regulate the engine temperature. When the coolant level drops below a certain point, the BMW’s computer system will trigger the coolant warning light. In some cases, the BMW may also display a message on the iDrive screen that says “Check Coolant Level.”
If you see either of these warnings, it’s important to check the BMW’s coolant level as soon as possible and add more fluid if needed. The BMW’s cooling system also includes a radiator, radiator hoses, water pump, thermostat, and engine fan. These components work together to keep the BMW’s engine at the correct temperature, and they can be damaged if the coolant level gets too low, leading to expensive but preventable repairs.
Five Indications of a Coolant Problem in Your BMW
BMWs are revered for their performance, luxury, and style, but like every vehicle, they require regular maintenance to keep them running smoothly. One important task is to check the level of coolant.
BMWs have a specific coolant that helps to keep the engine at the optimal temperature. If the level of coolant gets too low, it can cause the coolant warning light to illuminate to alert you to the problem. Luckily, there are warning signs that indicate when it’s time to top off the coolant level:
- The engine is overheating. This can be indicated by a higher than normal reading on the temperature gauge or by steam coming from under the hood.
- The engine is running rough. If the engine is misfiring or idling roughly, it could be due to low coolant levels.
- There’s an unusual smell coming from under the hood. Low coolant levels can cause a sweet or burning smell.
- There’s fluid leaks beneath the car. Coolant leaks are usually easy to spot because of their bright green color. If you see any fluid leaks, make sure to check the level of your BMW’s coolant right away.
- The coolant warning light comes on. This is the most obvious sign that there’s an issue with the coolant levels.
The Source of the Coolant Warning Light Illumination
Leaks are one of the most common causes of low coolant levels in BMWs. Engine sealants and gaskets can degrade over time, allowing coolant to seep out. BMWs with water-cooled engines are particularly prone to leaks, as they have more cooling components than other types of vehicles. If you notice your BMW’s coolant level is dropping quickly, it’s best to take it to a mechanic to have the leaks checked out.
Evaporation is another common cause of low coolant levels in BMWs. Coolant can evaporate when the engine is too hot, so it’s important to make sure your BMW isn’t overheating. A BMW that frequently overheats is likely in need of a new thermostat or water pump. Unfortunately, these repairs can be expensive, so it’s best to catch the problem early on.
Excessive engine heat can also cause the coolant to evaporate. BMWs are designed to operate at high temperatures, but if the engine gets too hot, it can cause the coolant to boil off. This usually happens when the cooling system isn’t working properly. If your BMW has been running hot lately, it’s important to get it checked out by a trained mechanic.
