Do This If Your Mercedes Says 'Check Coolant Level'
Do you have a notification on your Mercedes saying to "Check Coolant Level"? We are aware of the disconcerting nature of the display of such an error message. But fear not… Just because your Mercedes is displaying such an error message, doesn’t automatically mean expensive repairs.
In this article, we are going to help you understand what it means when a Mercedes says to check coolant level and more importantly what you can do to get rid of it.
Mercedes Says Check Coolant Level: Here’s What It Implies
From a simple issue like a low coolant level to a more complicated condition requiring component replacement, there are numerous reasons why your Mercedes may display the 'Check Coolant Level' warning on the dashboard. This blog post will outline a few things that you should check before reaching out to a mechanic
But before anything else, let's talk about the crucial purpose that cooling systems in cars provide.
The Importance of a Car’s Engine Cooling System
Your car engine works hard to generate the desired torque. This is achieved through the controlled burning of gasoline. The purpose of a vehicle’s engine cooling system is to eliminate the excess heat generated due to the combustion process. And, to do so… the cooling system makes use of the radiator, thermostat, water pump and of course… coolant.
All right… now that you know what function a car's engine cooling system serves, let's jump to the next topic which is- factors that can contribute to the appearance of the 'Check Coolant Level' warning message on the dashboard of a Mercedes.
Reasons Why Your Mercedes May Display ‘Check Coolant Level’
Reason #1- Declining coolant level
Coolant level is the first thing that you should check if your Mercedes' 'Check Coolant Level' message comes on. Coolant is the lifeblood of a vehicle's cooling system, as this fluid circulates between the engine and the radiator to remove excess heat created by the combustion of gasoline. If the coolant level drops, your entire cooling system will fail- which may result in engine overheating and other problems.
As a preventative measure, modern cars come equipped with sensors and computers that monitor the coolant level and notify the driver when it drops below the minimum level.
Reason #2- Faulty cooling system parts
Yup… your Mercedes' check coolant level message may come on because of a defective cooling system part. Why so, you asked? To be precise... a specific system is in place to ensure that coolant absorbs heat generated by the engine and disperses it to the outside air. Some of the major parts that make up that system are the water pump, thermostat, radiator and coolant reservoir.
In the event that any of these components malfunction, the cooling system will become inefficient- which may prompt the onboard computer to display the ‘check coolant level’.
Reason #3- Clogged radiator/hose
The radiator, as most of you probably know, is a device that pulls heat energy out of the coolant and radiates it to the outside air. However, it can get clogged with dirt and other airborne debris. If your Mercedes' radiator is clogged or damaged, it may restrict the coolant circulation which may prompt the onboard computer to set off the 'Check Coolant Level' message on the dashboard.
Reason #4- Faulty sensor
This might seem silly, but it happens all the time. The sensor that serves to keep track of the coolant level, if goes bad, can feed misinformation to the computer and may cause the ‘Check Coolant Level’ message to come on.
Mercedes’ Check Coolant Level Message On? Do This
While you can always reach out to a trained car mechanic to diagnose and treat such a problem, there are a few troubleshooting tips you can try first.
Check the coolant level in your car regularly.
If your Mercedes is leaking coolant, find out where the leak is and fix it.
Make sure different parts of your vehicle's cooling system are in good working condition.
Last but not least… check the sensor that is employed to keep track of the coolant level. If it is faulty, replace it.
In Closing…
The 'Check Coolant Level' message in a Mercedes car usually comes on because of a drop in coolant level. But, issues such as a defective water pump, clogged radiator,
and faulty sensor may also result in the appearance of such a warning message. In any case, you should take analogous actions before things take a turn for the worse.
