Glow plugs

[Stumper]

I know that I can find printed instructions somewhere but there are so many savvy guys on the site I thout I'd ask-What's the procedure for changing the Glowplugs on a 7.3 litre Navistar('89 International S 1600)?

Just unscrew them and remove.Sometime the end gets mushroomed(out of round) and they can be a bugger to get out.Install them with some anti-seeze on the threads.It is pretty simple.
