Here, drivers may choose between several brands, with most of them being available in several colors. When this becomes a challenge is when you try to buy a Mercedes-Benz engine coolant from an auto parts store. This is straightforward when buying at the Mercedes dealership, as sales agents know the correct coolant. What is the correct engine coolant for Mercedes-Benzīefore filling up, it is important to find out what type of coolant should be used.

On newer Mercedes-Benz cars, coolant may also disappear because of cracked oil coolers and EGR coolers on vehicles with diesel engines. Symptoms that would reveal this condition include white smoke coming from the exhaust and rock-hard coolant hoses. The most common failure that causes this is a broken head gasket, allowing coolant to enter the combustion chamber.

Most of these will cause puddles of liquid under the car unless the leak is minor.Īnother possibility is an internal leak such as a blown head gasket, where the coolant gets into those engine components it should not go in. This can be anything from cracked hoses or leaking radiators to broken coolant bottles or worn water pumps. Possible reasons for the lack of coolant fall into two major categories are: external leaks or blown head gasket. The cooling system is a closed-loop, from which nothing gets out under normal running circumstances. You may be able to drive as long as the engine doesn't overheat. If the engine temperature rises when driving, or there is steam coming from under the hood, you must stop immediately, turn off the engine and let the engine cool down. Do not drive the vehicle if it starts to overheat. If the warning comes up again and the engine starts to overheat, your vehicle may need to be towed to a mechanic. The only way to determine this is by visually checking the level inside the coolant reservoir.Ĭheck the engine coolant level and add coolant if necessary.

However, a driver can't know the actual level from the message displayed on the cluster. When an extensive amount of coolant is missing, the engine will overheat within a few minutes. When there is not enough coolant inside the cooling system, the coolant (if any) will lose its ability to cool the engine. Is it safe to drive a Mercedes-Benz with a coolant level warning on? If the engine coolant level is low, add the recommended Mercedes-Benz engine coolant directly to this coolant tank.With a cold engine, it should be just at the top of a marker bar inside the filler neck. Once the cap is removed, it is possible to see the coolant inside the bottle and check its level.Ideally, this should be done only when the engine is cold, ensuring an accurate reading. Next, remove the cap from the bottle filler neck by unscrewing it counter-clockwise.This will be a plastic tank with a cap on top of it. Lift the hood and locate the coolant bottle within the engine bay.Pull the hood release under the dashboard, driver's side.

How to check the coolant level on a Mercedes Benz?Ĭhecking the coolant level is quite similar on most Mercedes Benz vehicles, although some differences may be possible. The car will warn the driver immediately if the level falls below a certain level.

Mercedes-Benz cars have a sensor that measures the level of coolant within this bottle. Most systems also have a coolant bottle (overflow reservoir), which acts as a buffer that allows the coolant to expand. There is also a thermostat, which controls coolant flow to ensure optimum engine running temperatures. When the engine coolant level is low, the water pump may not circulate coolant and cool down the engine.Ĭoolant goes through several hoses towards the radiator, where it cools down and heads back to the engine to repeat the cooling process. The water pump pushes the coolant inside the engine, taking away the heat generated by combustion. This means that the engine may overheat if you continue to drive. The Check Coolant Level message indicates that the coolant level in the radiator or coolant tank is below the minimum. What does the Check Coolant Level message mean? In addition, we will go through what drivers should do when checking coolant level warning comes up. In this article, we will explain what this warning means and what may cause it. Is your Mercedes-Benz showing a Check Coolant Level warning message on the central display?Įngine coolant, also called antifreeze, is important for engine operation, as a lack of it may result in overheating.
