Thanks for your question and I will be glad to help. I will follow this post with instructions from the ford workshop manual. If you have any questions please feel free to ask. The replacement of the glowplugs is pretty straight foward but requires a special too to remove the harnesses to prevent damage of the harnesses(although harness damage may happen even with the tool). May I ask why you are wanting to replace the glowplugs?
