Symptoms of Issues With Your BMW’s Coolant System

BMWs can develop issues with the coolant system that can lead to catastrophic failures. While most coolant leaks can be repaired easily, ignoring the problem can lead to a lot of down time and unnecessary expense out of your pocket. Below, you will find more about what the coolant system does for your BMW and also the symptoms to look for if there is an issue with beginning to develop.

BMW Engine Overheating

Function of the Coolant System

The coolant system plays a major role in how successfully your BMW operates. The coolant system is responsible for maintaining the proper temperature in the engine of your BMW. As the engine is constantly running, it gets hotter and hotter. In order to prevent overheating, the coolant system is required.

The coolant system ensures that the engine can perform at an optimal rate since it keeps it at an optimal temperature. The coolant system is made up of many parts, including the radiator, water pump, thermostat, fan, and a series of hoses that connect everything together. All these parts work together to maintain the proper engine temperature.

Symptoms of Coolant System Issues

The first symptom that will alert you to a coolant system issue in your BMW is a consistently-high reading on the temperature gauge. The temperature gauge is located on the dashboard of your BMW. Your dashboard is what gives you many different readings about what is happening inside your BMW. The temperature gauge shows the current temperature of your engine. If you notice that the gauge is rising or remains in a high state, then you should pull over immediately and wait for the engine to cool down.

Another symptom that you will notice if there is an issue with the entire coolant system in your BMW is a steaming hood. Steam coming from underneath the hood is a sign of overheating and proves that the cooling system is unable to do its required function. A steaming hood means that the coolant in the engine has boiled and is now steaming. This is another instance where you would want to pull your BMW over to let it cool down. It would also be a good idea to add some more coolant to the system because a lot of it may have evaporated.

Additionally, a sign that can point to an issue with the entire coolant system is white exhaust smoke. The white exhaust smoke is caused by a coolant leak under the hood. In the case of a leak, the coolant fluid is burned during the combustion process. Once it has burned, what is left is white smoke. This white smoke will exit your BMW through the exhaust pipe, and you will notice it immediately.

When consistently driving your BMW, you will need to maintain a proper schedule for servicing and maintenance. One aspect of this is ensuring that there are the correct coolant levels in your BMW. If you or your mechanic notice that the coolant fluid is low, then more should be added. If you notice that the coolant is being filled up with every visit or even more frequently, then there may be a leak in the coolant system.

You will be able to tell a coolant leak from any other potential leak in your BMW because it is a bright green and has a sweet smell to it. So if you notice a bright green pool of liquid under your BMW, then you have a coolant leak that needs to be addressed.
