I know this should be obvious, but I'll post it anyways. My first HMMWV, a M998 from GovPlanet in Western WA was a '89 in great shape, came from a OR Guard unit with '06 MMA overhaul, 218 w/6.5. Fluids all looked fresh and correct but being anal I swapped everything fresh with Redline Synthetics, fresh DOT 5 & flushed and swapped the Coolant to DexCool.
2nd HMMWV I got, 2011 1097A2 from a Hawaii GovPlanet, wasn't able to look at it first but the video showed it cranking but no start. I figured that would probably be easy enough to figure out. Bid and purchased, when I got it the engine was seized solid, of course I made the mistake of swapping out all of the fluids, as they had all been drained, before I made an attempt to start it as I hadn't gotten batteries for it yet, waiting for that Costco trip. Still working on that one, not really but someday, maybe a Duramax conversion.
3rd HMMWV I got recently, a 2005 1097A2 Hawaii Govplanet. Took a set of batteries and looked at it in person and it cranked and fired up quickly. GovPlanet said they get their's in and they don't have fluid and if it supposed to be a runner they fill them.
Warining is, Brake fluid was filled with DOT 3 and not DOT 5, not a anti-lock brake HMMWV, not sure if the anti-lock brake HMMWV's use DOT 5. Transfer case was filled with what appeared and smelled to be 75w-90 gear oil. I flushed the brake fluid with fresh DOT5, probably flush it once more in a month just to make sure all of the DOT 3 is out. Driained the transfer case well and put in Sythetice Dex III ATF. Only driven it a couple of miles but it appears to be stuck for the most part in T/C locked. Came out once or twice but then seems to want to go back to locked. Dont' know if that is because of the gear oil previously? I double checked the linkage (first thing I checked) but it's fine. I'll drived it a few more times and maybe even drain & refill the T/C with ATF again, only take 2qts.
Moral of the story and like I said at the beginning it should be obvious. If you purchase a GovPlanet vehicle, swap out all of your fluids. And of course even if you're not going to swap them right away check the levels as my wheel Geared wheel hubs were empty on the 3rd HMMWV too even though GovPlanet said they had done the fluids.
