You will need an 8mm socket with various bends as they are very tricky to get at. Carefully unscrew the electric connection from the top then unscrew the glow plug itself. Remove from the block and replsae with a compatible plug. Attach the electric connection. Do this with the remaining 3 plugs.. Bobs your uncle
