Now I know this isn't required but I was wondering if anyone has done it? Was thinking about adding 2 more batteries in the rear and a equalizer between all 4. The only reason is we get some really cold days here was -20 the other day and while I have a block heater that doesn't do me any good...

after doing some reading on here I see that my trans light shouldn't always be on, was on when I got the humvee and had a code (73 I think) which I fixed but the light never went away the code just didn't flash anymore so I assumed the light was suppose to always be on. What non-code related...

My humvee has started to smoke on start up quite a lot for the first 3 seconds and then cleans up and is fine. Things I've checked so far: Glow plugs have 22.9v going to them when the Wait light is on. All glow plugs Ohm good but 1 is bad (open) on the rear drivers side cylinder. Vent line and...

Hey guys was wondering if anyone else has ran into this issue. My humvee is a 1097r with 6.5/4 speed and the front end seems to hop/wobble between 30-35mph but is perfect at all other speeds. Thought it might be my tires so I rebalanced them with weights twice and it didn't help, so I ended up...

Just a little story for ya on my first time changing one of these tires. after getting the tire off I unbolted the plate and tired it on the tire machine which didn't work so I thought to myself I would put 4 nuts back on the rim to keep it from flexing so the machine could break the bead and...

Was going up a hill which was really steep maybe 60% grade/angle (90% being straight up and down). I noticed some noise from the engine compartment kind of thinking it is power steering related but got leveled out and the noise continued. Decided to drive home about 10 mins away and the noise...

How much electrical dip is normal from turning things on like the headlights or fan? I noticed when I turn anything on it seems to work the system pretty hard. On the voltage gauge just turning the fan on high when idling will move the needle from fluttering right between the red and green down...

hello, I have a new to me humvee with the N/A 6.5 and 4l80e transmission and have been changing fluids and doing some little maintance and driving around town. everything seems good except the transmission seems a little confused if it should shift up or down in overdrive. found on here how to...
