Electrical problem
1992 Mercedes Benz Engine Size unknown Wheel Drive Type unknown Automatic 125000 miles
This is a 1992 300D. Where are the glow plugs and relay located, and how do I change them?
Thanks

Hi there,
The glow plugs are on the side of the cylinder head below each fuel injector. They are connected by a Buzz bar. (Heavy wire connector) Disconnect battery, undo all buzz bar nuts & remove individual bars (they are not specific to injectors) do not loose insulators if dislodged. Glow plugs are screwed into Cylinder head, undo and remove.
