Are you cruising in your BMW, enjoying the car’s performance and handling when out of the blue, you notice a warning light? After looking closely, you notice it’s a coolant warning light. If you are wondering what this means or how you can go about addressing it – you are not alone.
The coolant warning light is one of the most dangerous warning lights and if not sorted out immediately may lead to severe damage to your engine. This light is a signal that there’s something wrong with the cooling system of your BMW. Here are some of the steps you can take to fix the coolant light issue to ensure your BMW is always in the best condition.
How You Can Resolve Coolant Light Problems In BMWs
- Check Coolant Levels: The first and easiest thing you can do is to take your time to look at the coolant level. This entails taking off the hood to find the coolant reservoir. Ensure that the engine has cooled down before doing this – never remove the coolant cap while the engine is still running as you will be burned by the steam. If the coolant level is very low, you can augment it by adding some coolant and see if the coolant light will switch off. BMWs also need specific coolants that are often mentioned in the owner’s manual, so don’t use just any coolant.
- Look for Leaks: If topping up the coolant does not help or if you are often faced with the need to add coolant you most probably have a leakage. Start by doing a thorough check under the car for signs of dripping fluids. This fluid is usually colorful, normally pink, blue, or green, and has a sweet smell. Sometimes it may be challenging to point out if there is actually a leak, especially if the leak is internal or if it is dripping slowly. In such cases, you should take your BMW to a mechanic to have it checked.
- Inspect Cooling System Components: Your cooling system is made of several units that have to operate cohesively for everything to run as it should. Look at the radiator, hoses, thermostat, and water pump and see if they have any signs of wear or tear. At times, the coolant light can come on because one of these parts has gone bad and resulted in overheating or loss of coolant.
- Check Coolant Sensor: If the coolant level is ok and there are no signs of leakage then the issue might be tied to the coolant sensor. A malfunctioning sensor can give a wrong signal and the light flickers even when all is okay in the vehicle. A faulty sensor can often be replaced for a small amount of money and it does not take long to accomplish.
Visit a Mechanic
If the lights stay on after trying some of the above interventions or you have not been able to diagnose the cause, it is high time to consult a mechanic. A professional can tell whether it is a sensor problem, a leakage problem, or a more severe problem such as the water pump or the radiator.
