Glow plug how-to???

Does anyone have a step-by-step on how to replace the glowplugs? Its for a 94 IDIT.

If not, could someone explain it to me? I have to help out a friend, and i know the idea, but not the details.

Assuming it's a factory turbo, first take of the air cleaner. The top comes off with 3 bolts, and a couple hose clamps. Under the air filter are 2 bolts to remove the air cleaner base. Then on each glow plug, pull the electrical connector and remove the plug. You'll need a 1/4" drive, 3/8" deep socket, ratchet, a U-joint, and several extensions. I get to the ones under the turbo by sliding the socket/U-joint/extension from the driver's side of the turbo, underneath it...

Search this forum for "stuck glow plug" and read what to do if you have trouble getting any out.

Good luck!

the one set i removed were autolites which hadn't swelled yet, and some of them stuck to my socket as they came out, the others were simply lifted out with my fingers or a small pair of pliers. they're as easy as they can be
as you know, motorcraft plugs only, and put anti-sieze on the threads just in case you ever do change them again

After you change the glow plugs keep a close eye on your your return lines and caps. I changed my glow plugs and had had return line caps leaking. If you have not changed the return lines and caps I would do them at the same time.
