How can I fit new glow plugs to a Peugeot 307?

as you look at the engine you will see each glow plug below each injector normally 12mm spanner this is for the glow plug at the top there's a 8mm nut to hold the live power supply for all your plug's it's straight forward from here,remove the 8mm nut on the first plug,then remove plug,then replace the new glow plug screw by hand then tighten with spanner/torque wrench i think it's 12 nm then replace the wire at the top and the nut and tighten with spanner same again for all the other plug's hope this help's
