Sorry Thanks for the infoFirst off, please don't type in ALL upper case.
Ok, glow plug removal on a V1702 engine really isn't that hard, they are on the left side of the head looking in from the back. You will need a 12mm deep 1/4” socket for this. You may even need to remove or loosen the bolts on your inlet manifold to get the socket between the glow plug and the manifold. With that done, just remove and replace, they are very simple. Access is the only problem.
Good Luck.
