as you look at your engine you will see four pipe's & underneath these pipe's you will see a strip of wire with four nut's/bolt's through it each evenly spaced these nut's/bolt's are your glow plug's,they will have 8mm nut's holding wire & 12mm hex for the glow plug body they are right hand thread, & take care when you try to take these out,that they do not shear off, when replacing the glow plug's they are 12nm torque to tighten hope this helps
