It is well documented that the AC 13G plugs swell and can be a real pain to remove. The AC 13G is the original equipment plug that was used when these trucks were new and is what is probably in the TM. You can still buy them but don't, they are obsolete. Autozone has AC 60G plugs for $8.99...

I would like to go on record as never recommending the Wellman plugs. My original post was edited by one of the moderators. A couple of us went round and round about the best plug to use and I finally got tired of it and quit posting. I have used AC 60G in both modified and unmodified trucks...

NEW type glow plug relay - Michael's Photos The bid red wire goes on one big post and the two big orange go on the other. The small blue is on the top small post and the small pink is on the bottom. I don't think it makes any difference if you get them backwards since the two small wire...

You probably could, but it would have to be heavy duty because of the load. This is directed to all of the new guys, not just Alredneck. You should be asking these questions in new threads, not in this one. This thread is meant to be answers to FAQs.

You can buy them, but they aren't worth the expense and don't have much of a warranty. The battery tray in a CUCV is designed for 6TL or group 31 batteries.

The Commercial Utility Cargo Vehicle or CUCV Program was instituted to provide the United States military with a cheaper vehicle to augment the purpose-built, but expensive, Gama Goats and Humvees then coming into service.

You need to start a new thread with your question. This thread is for answers to common problems. Sounds like you have more than the common starter relay problem, but I think it still may be your main problem. GM used a off-the-shelf heater relay as a starter relay in the CUCV. Its purpose is...

RE: FAQ Thread for CUCV I would rate this as the third most common problem, but probably the most expensive one if you don't know what to do when it happens. CUCVs have an extra starter relay under the dash. It is known to either rust and not work making the truck not start or to stick in the...

RE: FAQ Thread for CUCV CUCVs use metric bolts so you will need metric tools to work on them. The main problems with CUCVs are charging issues and glow plug issues. The original glow plug relay was defective and should have been replaced before the truck left the service. If you have one that...

RE: FAQ Thread for CUCV Do not buy AC13G glow plugs. They are obsolete. I prefer AC60G which is what GM recommends for all civilian 6.2 and 6.5 engines.
