Dismantling and Fitting Glow Plugs on a Mercedes B-200

Model: Mercedes Classe B W245, MK 1 - Years 2005-2011
Part: Glow plugs

Is your car indicating a glow plug warning light? In this video, we will see how to maintain our Mercedes B-200. Open the front bonnet of the engine bay, locate where to work on the part, and equip yourself with a socket wrench with the appropriate insert. Start unscrewing the glow plug located in the engine block as shown in the video. Once unscrewed, compare it with the new one; ensure to install the same type of glow plug to avoid issues. Use your wrench to screw the glow plug into the engine block, being careful not to overtighten it to avoid breaking it. Check the instrument panel to see if the warning light is still on. Use the same procedure for the others.
