It gives you a notification when your coolant level is dangerously low, so you would know before the coolant causes various problems on your vehicle. Cool, isn't it?

To let you understand your Mercedes Benz Slk280 coolant level sensor more, here are some tips on how to diagnose your car problems that could be related to it:

Engine overheating

The coolant level sensor alerts you whenever there is an insufficient level of coolant in your system. But when it fails, you won't know whether you are running low of coolant and your engine is at risk of overheating. When your engine overheats, there are several problems that could arise, especially if your engine head cracks. This would result in reduced car compression, which could make your car hard to accelerate. Before this happens, what you can do is to check if the magnet attached to the coolant level sensor becomes loose or has fallen off. Unfortunately, you have to replace it or use a black tape over the warning light and monitor the levels from time to time.

Wrong signal

If you have been experiencing a hard time knowing your correct coolant level due to the inconsistent signals that your sensor is producing, then you need to check the connections to make sure that there are no loose wires that could cause this inaccurate readings. To check if your sensor is working, unplug it and then start the engine. If the reading displays code 13, then you should check it for a short circuit. But if the reading displays code 16, then you need to replace the sensor and test it afterwards. Sometimes, it could also be due to a faulty coolant level sensor switch that might have worn-out over time. In any case, you need to replace any damaged part with a new one immediately to restore your coolant level sensor's functionality.
