I have never put glow plugs in, is there anything particularly tricky I should know, I have a 1997 K1500 6.5 (S) model and I ordered the set Kennedy has on sale.

I like ti use dielectric grease on the threads, plus the terminals to prevent rust. Some use anti-seize, but I find dielectric to last longer especially with the heat.

Alldata shows that I need a glowplug socket to replace the glowplugs. They refer to the part number as "J 41515-A Glow Plug Socket" Is there anything special about this socket or will a deep well socket of the appropriate fit work? Do I have to take any parts off such as the turbo or starter? Thanks in advance
Nope. Just a deep socket, or box end wrench where the socket doesn't fit.
Hello CCC and welcome.
Last week I put in 7 of the 8 Kennedy Glow Plugs I purchased. They seem to be a great product and I believe it is a 10mm deep well that I used to remove the old and install the new.
The reason I say 7 of the 8 is because the entire pass side is a challenge and there is one glow plug behind the down pipe which is especially tricky. I was advised to take the inner fender out of the pass side to make removal and replacement easier...this is good advice and allowed me to get right in after the plugs with a straight shot.
I think I will be able to get the last plug with a swivel/extension setup but have not been able to work on it yet so I cannot be sure. I highly recommend removing the inner fender for this operation it makes the difficult pass side plugs much easier.

Keep a short 6" piece of vacuum hose to fit over the spade connectors to use as a means for threading the glowplugs in and also to back them out. It allows you to feel the plugs thread when starting.
Did all mine on pass side through wheel well with dust shield removed including the one hidden by the turbo did the back one on my back. also removed the heat shield tubes,made things real easy. 45 mins.
Good Luck Dave

My trick was to hole saw a hole in the inner fender in a location so a very long 3/8" ext could reach. I stand outside the fender to reach it now. Use a solid plastic gromet to fill the hole when not in use.

Thanks to all who helped with the glow plug change out, I put 7 of 8 in and may or may not put the 8th in. The plugs that came out were very wet with fuel. When I buttoned the truck up and tried to start it, it didn’t start. I tried several cycles but all I got was a lot of white smoke. I then let the truck sit for a while and thought about it. I got a code P0380 which my reader tells me is “Glow Plug/Htr malfunction CKT A.” I didn’t know what that meant but it sounded like there would be a CKT B, so considering there are two wires coming off the glow plug relay, I checked them both to see if they were connected tightly, and then checked the grounds. I then pulled a connector off a glow plug on the passenger side, hooked the positive connection of a tester to it and the ground of the circuit tester I hooked to the negative on the battery. I then turned on the key and got a voltage reading of about 10.5 volts for 9 seconds. I did the same test on the drivers side and got the same reading. After I put everything up, I tried the truck again and it fired right up. Why? I drove the truck for about an hour and then turned it off and started it three or four times in about a 15 minute period. I’m glad it’s running but why wouldn’t it have started the first time? Would cycling the glow plugs have anything to do with it (the temp is about 34 degrees, the truck was not plugged in) or do I maybe have short in the harness? By the way, thanks to John Kennedy for the quick heat plugs they not only work a lot better than the ones I took out, I had them in two days!

Can anyone tell me what P0380, “Glow Plug/Htr malfunction CKT A.” means?

P0380 means what it says, except the "heater" part (the 6.5L doesn't have an intake heater). One or more failed glow plugs, or a failed glow plug controller/relay is most common. If all the plugs check out, look to a poor connection or failed relay. Any significant current draw variation will cause the code. The PCM monitors line voltage during the glow cycle, and will complain if the value is out of spec. This could also be caused by marginal battery health, or poor connections.
Thanks DmaxMaverick, I changed out the glow plug controller. I took the old controller apart and found a burn spot on the coil that is part of the electromagnet, I suppose it is shorting out. I found it was working sometimes and other times it didn't. With the replaced glow plug controller ($10 at the bone yard) and the new quick heat glow pluggs from Kennedy, the truck started with the outside temp at 6 degrees without a block heater! This truck NEVER started below 20 degrees before. Thanks to everyone for all the help, I even got the four wheel drive working. Life is good.
