Where did you get the plugs? 10 mm might be for the imported ChingV ??, CAMOToday was glow plug day. EDIT to add: 6.5 Turbo
I started on the right side aft plug. I used the medium pry bar to bend the heat shield out of the way some. That one took a while. Open end wrench 1/16th of a rotation each time.
I did the next forward one and it took about as long, again bending the heat shield out of the way and using an open end wrench. I did bend them both back.
After lunch I did the left side in about 15 minutes- easy to get to from the creeper underneath. 3/8inch drive socket wrench made it easy.
Moving back to the right side I pulled the air duct off the air cleaner for more access, and used a zip-tie to hold all the lines/wires/hoses out of the way. For this one I changed to a 1/4inch drive socket.
The last one, second from the front on the right, was the b*tch. I disconnected the coolant hose and moved the hard-line out of the way to give more room, but that (of course) spilled slippery coolant in the place I was working. I was working from the back (passenger seat) and from the top, and got the old one out. Going back in was harder because you can't see the hole, you just have to sort of feel your way around working from the rear.
The old glow plugs used a 3/8inch wrench/socket. The new ones used a 10mm.
All but one were bad. 4 of the 8 were OL on the meter, 2 were in the K-ohms, one in the M-ohms, and the right forward was 1.9 ohms. None were swollen.
Lot of work but glad it's done.
