Remove Glow plugs Mercedes vito

Answer 1

The reason for this problem is the corrosion between the glow plug threads and the cylinder head. A lot of engines have this problem (in fact a risk at most engines, a lot of problem also with injectors and sprak plugs)) An excessive force with a torque wrench may cause the glow plug to break, or lead to damage to the thread. If this happens, the mechanic does not really have any choice but to remove the cylinder head from the engine to extract the glow plug (and high repair bill sure >1000$). There is are solutions on the market for this. Most of them are very expensive tools to pull out the glow plug. There is one new solution named vibropac, see www.vibropac.ca. This product is just on the market in Nort-America, it was designed in Europe for cars having this problem. This tool vibrates the glow plug, ensures the material forces of corrosion and dirt are breaking and are minimized and at the same time, using force to unscrew the plug. Good luck.
