Now a leaking water pump gasket? I'm starting to lose coolant and now seeing a seepage puddle beneath the HMMWV that's just come to be in the past two weeks. Based on wetness on the engine block, it looks like the gasket between my water pump and the adapter plate is leaking. Is this common...

I rode that ten years ago on my shovelhead going out to visit relatives south of Chincoteague. The bumps of the bridge weren't too bad but it was 30mph crosswinds the whole way back and I HAD to be at work on Monday and dog sitter was leaving Sunday day afternoon. It took 8 hours to do what is...

Installed new oil pressure gauge and sending unit, courtesy of Erik. Working well. Still have the mechanical gauge plumbed. Will run it a few more days before going back to stock. So far so good. Bulldogger

Well gents. The problem seems much more clear now. I plumbed a manual pressure gauge and did some driving. Took a little more time as I gathered fittings so's I could have both the factory electric gauge and new manual gauge connected at once. After some highway driving, the dash gauge would...

I haven't made time to install the mechanical gauge, but just changing the oil to rotella 15w40 and a new filter has doubled the idling hot oil pressure. Funny what the right (or better) components will do. I will still put a new gauge in but so far things are definitely improving. I'm glad for...

orgnal, the trans doesn't drop down a gear when I floor the pedal or when hill climbing, etc. The kickdown switch "clicks", but I haven't had time to test it for continuity. I have verified the kick down solenoid is in place at the transmission and is connected to the other end of the wiring...

There is nothing wrong with painting your truck how you want it, and I think anything that is pro-military in nature is sorely needed in our society right now. PLEASE PAINT YOUR TRUCK IN MILITARY COLORS! Paint your car, your house, your kids in military colors! (OK, maybe use something...

On the suspicion that my HMMWV has less than perfect grounding, I went ahead and put on my homemade grounding harness last night. First thing I noticed digging around is that the ground lug above the fuel filter was loose. This is the ground lug that on the inside of the dash happens to...

Installed my homemade grounding harness last night. It seemed to positively affect the accuracy of my oil pressure gauge, at least in the amount of time I had to test drive. Time will tell. Have to get the gumption up to replace the weeping steering pump next, and fix the transmission kick...

DatGuyC, the fan is locked when the motor is off. It only seems to kick on high speed when the vehicle is moving though. I installed my grounding harness last night, and that included a ground to the EESS, so I will see how/if her behavior changes as I drive her. I took a 15m test drive...

Thanks gents, I appreciate the feedback. I can easily hook up a mechanical gauge, and happen to have more than half the setup handy from a motorcycle diagnosis project earlier this year. I am happy to change to 15W-40 RWH, especially considering the advice comes from you. I bought it by...

My 1987 M998 has been doing fine. We went to Graves Mountain and had a blast last month. Acted odd yesterday, so bear with me while I try to give you experts all the information I can... Coming home Sunday evening from TheCaptain's place, I noticed after a long haul (25 miles maybe) at...

Agreed, normal. Don't feel bad for asking though, I didn't know about it until I asked! That said, it should only last a minute or so and stop. If yours is going much longer, then yes, something wrong. Bulldogger

I have been looking at similar systems. The motorcycle clip-on communications boxes have a mike and speakers. I figured I'd shove them inside a set of inexpensive ear muffs and go. Just haven't gotten to it. If you are looking for "cheap and/for now" there are wired intercom sets on Amazon...

Oh, I did do a little work on my own HMMWV yesterday I should take credit for. Before heading out to TheCaptain's place, I pulled the heater blower motor and fan out and cleaned it all up. There was lots of debris, sand mostly, in the heater blower plenum, and the fan was a little out of...

Thanks for those tips gents. The thought occurred to us, but taking all that off sounded like even more work. I suppose once those coolant hoses and fitting come off once, and get replaced as needed, it's easier the second time. TheCaptain is replacing all engine coolant hoses already, as...

Spent 4 hours yesterday afternoon helping TheCaptain tear off his water pump. Definitely a two man job. My advice is get two OTHER men to do it if you have one needing replacement. Getting the fan off was the hardest part, besides having to break a lot of very rusty long-tight bolts and studs...

Is that a recoilless cannon? Yummy!

My stalling at low RPM at letoff of the pedal in my HMMWV was due to dirty injection pump from long sitting and low running time. Cleaning filters and running fuel treatment has completely cured it. Sounds like you just need to drive her good and hard with your choice of treatment in the fuel...

Patience on eBay paid off after a couple months in my case. It's expensive to be in a hurry with these vehicles, when looking for parts... Bulldogger
