How to replace the coolant in the Mercedes GLB.

Model: Mercedes Glb MK 1 - Years 2019-2026
Part: Antifreeze coolant

Below you can find information on how to replace the coolant in your Mercedes GLB. The steps are really very simple and quick, and they are as follows. First, let's open the hood of the car, then locate the radiator reservoir, which is on the left side of the engine block, as we can see in the video. At this point, after checking that the fluid we are using is the correct one, we will unscrew the cap of the reservoir and, using a funnel, pour the fluid into the reservoir, staying between the minimum and maximum capacity levels. It is important to perform this operation with the engine cold.
