Penetrating oil on the threads first and let it soak. If a glow plug seems "stuck" - that is it unscrews but won't come out of the hole - do NOT try to force it out or "yank" it out, you will break the glow plug in half and then be REALLY screwed with half of it still inside the prechamber/cylinder - it means that the glow plug has swollen due to overheating. There is a specially made tool designed to carefully ease the swollen plug out of the hole, I think several members on here own one and it's available to be lent out.
When installing the new plugs, a small dab of antisieze on the threads and don't over torque them.
