On the 617 Engines is most often very straight forward as it is very unusual for there to be a stuck Glow Plug.
On the Engines with Aluminum Cylinder Heads and the longer Glow Plugs it seems to be from what I have read 25% of the people removing the Glow Plugs will have trouble with 1 or more stuck Glow plugs.
Similar to but not as easy as changing spark plugs but easier than doing something like the Brakes.
The job can be done with a 17mm wrench to Remove the Fuel Injection Hard Lines, an 8mm or 5/16 inch wrench or socket to remove the nuts that hold the Glow plug Wires on and a 12mm Wrench or socket to unscrew the Glow plugs.
After that you need something to clean the Carbon out of the Glow Plug holes. You can buy a Glow Plug Reamer or I believe some alternative methods are discussed in the DIY section.
If you removed the Fuel Injection Hard Lines you will need to know how to bleed the air out before Cranking. Simply only tighten the Fuel Injection Hard Line nuts at the Injectors by Hand and back them off a turn or so. Crank the Engine until you see Fuel coming out of all and then Tighten the Nuts.
After that go through your normal starting proceedure and Start your Engine.
(If you ever run completely out of Fuel and had been cranking the Engine trying to start it you will need to do the air bleeding as above (after you have fuel in the tank) except that this time you have to loosen the Hard Line Nuts at the Injectors first.)
Some were in the below links there should be a proceedure.
