To clearify we own a private beach house on private roads. The Humvee lives out there. I unplugged the time delay module tonight and the fan kicked in. After hearing the fan I can't say that I've heard this come on while driving. Would a bad time delay module cause the fan to not engage and the...

Driving home tonight. Temps where in the 200-220 range. But any long periods of idling or moving slow and temps creep up.

Nine! Nice! I've read from a few places that temps in the 230's isn't bad. What are your temps like in summer months just cruising around? Do you ever have any over heating issues? Mine hit 240 so I question what the fans doing.

ill check the fan tomorrow and see if it kicks in when it's supposed to and functioning. I'll post tomorrow when I got some more info. Thanks

Driving around it stays at about 200. It shouldn't be running 240 in this weather not being abused. It seems like every time I open the hood the fan is spinning. I'll do a coolant flush just to be sure fluids are good. Old t stat was a little crunchy. I'm considering running a top aux fan since...

Isn't the 6.2 a belt driven fan off the motor?

1993 Humvee with 17k. Replaced thermostat suspecting old one was stuck. New NAPA one I believe it's a 190. Seemed fine for last couple days driving around about 40 mph weathers been in the 50's. Same weather today driving on the beach slower speeds, humvee gauge reads 240. Is this normal for...

Thanks guys. I ended up finding a ground plug disconnected right over the trans in the ground cable cluster and it looked like someone had cut another ground wire at the plug. I had to cut the wire cover back to get the end and solder a new connection. Once I pluged them both in all my gauges...

Thanks NDT. Found a good write up on supplemental grounds. Going to give it a try tomorrow

With the humvee running i am able to get the back lighting to work but no actual function from the gauges. Oil pressure needle jumps to 0 then stops. Nothing from volts or fuel. Tanks full and bats are new. I tried a new oil gauge just to see and it does the same thing. Thought it was...
