Just looking for any members in Central Florida that might be able to recommend a shop to change out stuck and broken glow plugs in a 6.2 Detroit Diesel? Not many shops are willing to work on Humvees :(

200AMP ALTERNATOR / GENERATOR DUAL VOLTAGE. 14v & 28v - Niehoff Asking: $800 obo – no trades. Paypal ok, so long as there are no fees on my end. Manufacturer Part Number: 2920-01-458-9238 Not listed as a HMMWV part but another unit fit in my M998. I can provide more information if needed on...

Again looking for advice from the collective. As I put in a post previously, I made the mistake of attempting to change out my glow plugs myself. One head had one that was rusted to the treads and would no budge with a breaker bar and rounded off the head. Another on the other head actually...

Was busy today trying to replace all the glow plugs as a maintenance item. Got busy on the pass side, cylinders 8 & 6 went smooth. Cylinder 4 was seized. The officer I bought the M998 from said he replaced all the glow plugs, but #4 was a different shade and I think he never did #4 as he did...

Hello once again. I tried searching. I beg the collective for some more of your fine advice to help me avoid wasting tons of $ Before I upgraded to a 200 AMP generator, the Wait Light did not light for the last couple months. I would wait a minute after turning to run and the truck would start...

Hi there. Another opportunity for you guys to mock me. I am planning on installing a rear winch. I have the m998 WINCH MOUNTING PLATE 12469385 REAR 5340-01-485-5962 I assume the rear lower a-arm bolt goes to the the yellow arrows. I don't have much of a shop, and I am old and feeble. I...

Hello, Once again I ask the collective for guidance on a question I came up with regarding upgrading a 60 AMP to 200 AMP gen. Please reference this YouTube: at the 16:30 mark. The creator references that there is a second cable supplied in the conversion kit that goes to the first battery...

I am hoarding parts for a 60 Amp to 200 Amp generator conversion and I need the knowledge of the collective again. This time, it is belt routing after the conversion. I bet there is someone here that has a 200 AMP generator with AC and can tell me how their v-belts route! A "Normal" M998 with...

Yet another request from the collective on a shortcut or procedures to help me save tearing up my hands, destroying my radiator, or breaking my fan. Once the Florida Inferno subsides in 5 months, I am going to replace all the V-Belts on my M998 6.2 NA and replace the Fan Clutch Host with one of...

Once again the NOOB must come to the collective to get advise. Recently, I began hearing a whistling noise that I have been unable to track down. At first I thought it was bad belt(s) or a bearing going out, but now I think it is something else. It sounds like a whistle to me. Maybe a vacuum...

Hello again folks. Another newbie question here. Possibly something I am concerned about for no reason, but I will ask anyway since is the first diesel engine I have owned. I understand it is possible, but not likely, that the 6.2 NA can run away under some unlikely conditions. So I am thinking...

Yet another newbie question for the experts. I was thinking of mounting a rear hitch on my M998, using part number 5340-01-485-5962, this Humvee m998 WINCH MOUNTING PLATE: I have this bumper and receiver. Will 5340-01-485-5962 work on the bumper I have and will I be able to keep the...

Folks, My luck just seems to be going from bad to worse. I am working two different AC problems in different threads and now another horrible issue developed. When starting the engine I heard a horrble grinding sound while cranking. I get under the truck and pull the Torque Converter cover...

Yet another question for the collective. I did scan the electrical diagram I have for the M998 but I am not seeing this Fan Sensitivity switch. After converting my TH400 to a 4L80, I moved the Fan Sensitivity Switch that was located on the throttle body, to the back of the engine. I used the...

I have done lots of successful AC repairs in my time on a bunch of cars. But since I don't have much experience with my M998, I thought I would ask the collective's advice. When I first got my M998 last year, the AC was a bit warm, and the sight glass showed bubbles. So I added about 3/4 of a...

Another Q for the collective. I have seen HMMWV that have rear AC installed. I did some quick searches and did not find any kits that have rear AC. My current AC is the one that mounts under the radio shelf. I supposed there might be some generic parts for civi trucks but they would be 12...

Another question for the experienced folks here. As I mentioned on my other thread, I recently installed a set of skid pads from Jeremy Johnson. He certainly does great work. I mentioned that when I turn the steering wheel all the way to the right stop, the right outside of the right tire rubs...

I was installing some sound/heat insulation and I got to the driver's side under the dash area and I spotted this thing pictured below. Does not look like something the previous owner installed, but what do I know? It goes inside a tube that just is opened on the other end just out of the...

I tried to do some searching but I am not finding what I need, so I thought I would ask. I may not have the correct name for them, but I want to carefully remove the interior "hush" panels, or whatever they are called. They are green and look like they are made of some kind of foam. For my...

I free admit I am a newbie, and I have two silly oil change questions as my next oil change in coming up soon. M998. Last time I changed the oil, I finished up and started the engine to let it cycle before I checked the oil and discovered that the brand new pristine oil on the dip stick was...
