The hydraulic line controls the fan clutch. For deep water fording, you can go pedal down once and the fan will stop so it doesn't destroy the fan when it goes unfettered water. For the sake of non destruction, pop the back of the geared hubs off and make sure the spanner nut and star washer that hold the lower hub shift in aren't backing off. I've personally been in a few that did and it causes the wheel to exit the vehicle

[@gwbuilder5779]

The hydraulic system also controls fan speed. The clothing hub assembly may need to be replaced like many other parts. I would swap the hub from the other unit to validate because it did not have the same issue.

[@nerfo2]

I think it's important to note that the fan clutch is hydraulically released, spring applied. If it's unplugged, the spring applies the fan clutch, so the fan spins water pump RPM all the time. If the engine is cool enough, power steering pump pressure will release the clutch. The fan still spins a little bit because the power steering fluid (probably ATF) is still being churned inside the clutch housing. The temp sensor, fan clutch control module, solenoid, and fan clutch itself are probably four of the most reliable components on a HMMWV.

[@gwbuilder5779]

@@nerfo2 Good point. The fluid will cause the clutch to behave similar to a viscous type fan with the added benefit of the pressure engagement, which is why the engine stopped overheating once the hydraulic line was disconnected.

[@Zericef]

Important to note there's a plug you can unplug and it serves the exact same purpose. Most humvee mechanics know, when you unplug that connector the fan clutch will remain engaged, and the fan will spin continuously at it's max rpm.

[@timteecvhn]

The funny thing is, that I think the reason people say these humvees are usually slow is because of their usual top speeds they have when they are weighted down by their armor plating they *typically* have. But since yours is of course, a surplus one that the Military no longer wanted, it isn't weighted down by it's armor it had, and therefore can go faster than it's counterparts that are still in use.

[@Dwendele]

That, and the governor has definitely been removed. The look you gave when you said "it's almost like they were built for the desert".... Yeah not quite. They were a Cold War addition to the military. They were more designed for the German and other European forests and hills/mountains and the mud you get there.

[@BlueTeam-John-Fred-Linda-Kelly]

It was never armored in the first place, it doesn't even have the aluminum doors/roof it's half tarp.

[@timteecvhn]

@@BlueTeam-John-Fred-Linda-Kelly Well... I say armoring even though these things never really had much to begin with when it was used in the military. (they aren't really well known for being bullet proof persay in regards of actually stopping the types of calibers you'd find across the world that have been used in wars that these sorts of humvees have been in.) In essence, it's more of a case of they did have armoring when the military used them but... It wasn't really much, and even still it would've had some weight to it. Plus this humvee isn't... exactly a new one either. Nor would they really use aluminum in a military humvee anyways for the main bulk of the body and chassis, even though yes the doors and roof are fabric rather than steel, but then again those are pieces that can easily be replaced if need be. Overall, it did at one point have armoring, but since it is a surplus vehicle that was auctioned off, it's armoring, as Ethan and the others stated in the first video on these humvees, was removed before they got ahold of the humvees.

[@timteecvhn]

@@Dwendele Yea, technically you are right, but that doesn't mean they can't go in the kinds of terrain you find in Utah though, as clearly demonstrated by Ethan, that it is most definitely capable, just, not the environment it was originally intended to be in when they were first made for these vehicles.

[@davidanalyst671]

humvees don't TYPICALLY have armor. I don't know where you get your info, but thats wrong. The really wild delta and spec ops will delete the roof and doors on their patrols so that if they get ambushed, they can hear where the shots come from, and react faster than if you have armor doors and a roof that get in the way.

[@kimber3865]

The cooling system is not that difficult on a HMMWV. The radiator overflow ensure the radiator is filled properly by feeding to the bottom of the radiator. the two hoses from the radiator and top of thermostat housing is for overflow. As long as the engine oil is not milky and the exhaust is not smoking white fill the overflow bottle to recommended fluid level. If overfilled the overflow bottle will then overflow out the hose onto the ground. Use a conventional radiator bypass cap that will allow pressure to release past 15lb pressure. If overfilled the fluid will spit out and steam, appearing to be "overheating" 220F is when the radiator fan clutch will activate and keep the engine below 220F. IF the temperature goes past 220F even with the radiator fan clutch active, that's is when your HMMWV is overheating. This could be the thermostat or waterpump issue. You disconnected the hydraulic fan clutch line which forced the fan to be on all time. keeping the engine colder than 160F may cause damage to bearings due to being too cold. 1. reconnect the hydraulic line 2. refill to proper levels with IAT coolant 50/50 3.make sure you're actually overheating and not thinking you're overheating due to high temperatures. If you're reaching 220F+ with fan clutch on and is going towards 240F shut down engine and replace thermostat and waterpump. There's a lot of current and prior service military mechanics with years/decades of experience. reach out and get some help.

[@SmolPotatowo]

To be fair they didn't really have time to just go and get help while on the road like they were. Also it's generally less entertaining for a video when everything goes right. Now that they have it back home I'm sure they'll look into it properly

[@CommieHunter7]

My thought went somewhere similar when they were spewing pressure at 205. The system should hold everything in until well over boiling. If it isn't, I would have gone radiator cap first. And don't overfill.

i know this may be later than when you guys made it back but the hose line you disconnected is for the fan clutch. there is a black box on the driver side that you can disconnect instead by the washer fluid that will allow the fan to spin freely without blowing up the radiator. Its called the time delay, it connects to a thermostatic switch directly behind the thermostat that tells it to allow the fan to spin freely.

[@DB-yj3qc]

Actually that was what I came to the comments to type in.

[@Fate3d]

Around 220F to 240f the fan clutch will engage and its very loud and will cool down fast and turn off. These run very hot at high pressure. I replaced the overflow tank to a alum. type. Plastic ones will fail in time. Also looks like the thermostat is bad or your fan clutch is not working right. Fan Clutch line connects to the power steering lines and controlled by the cylinder valve device next to the washer fluid tank. Its orange or silver looking .

One of the best ways to depict steep hills on camera that i have found is to have the camera in the car and the car on the steepest part of the incline and then have a person stand up straight within view of the camera outside the window but orient the camera so the person outside the car is vertical in the camera frame. The angle that you see of the window frame against the person standing shows how steep the hill is. That is to say you can look at the window angle to see what angle the incline is.

I used to work on these in the army. There is a little electrical box called the time delay module. It controls the fan speed.

Might help your overheating issue if it gets unplugged.

The reason you're overheating at highway speeds is because the shape of the Humvee makes it so that at 55mph+ it creates a pressure bubble over the hood which keeps air from flowing through the radiators. If you keep it 55mph or lower (what it was designed for) you will never overheat. We H1 owners have the same problems. Your fan clutch should have kicked in to try and keep it cool. Unfortunately you probably destroyed that block when you overheated it.

[@nothingtoseaheardammit]

@rustyiron Sadly that won't really help either. Its the windshield that causes the problem. AM General spent time (actually in Vegas) in a wind tunnel trying to figure out solutions to the problem... in the end the only thing that was able to overcome the problem was the most hideous looking air scoop over the hood grille. The front of the scoop has to protrude in front of the hood in order to get enough air through the cooling stack.

[@JeffreyAllanBackowski]

I drove one across Kuwait and Iraq, stopping only to fuel, three days straight off roading, those things can almost literally drive straight up a cliff. I actually drove off one off a cliff, I thought I was going to die but the HMMWV was clinging to the side of this shear drop, any other vehicle in the world would've rolled down the cliff. The unarmored ones are so light, it's just 4 wheels and the big heavy engine close to the ground, those things are impossible to flip. We had hundreds of those, and they all made it just fine no issues except at the very start, one wouldn't start, I'm actually the one that fiddled with the wires to get it to start. Super fun for off roading, but driving long distances on paved roads sucks, they can't go very fast because they are in 4x4 all the time. I wish I had one of those old HMMWV's, I kept it in perfect running condition, I had to, it absolutely could not break down or fail in anyway because then people die, if that thing would've stalled or faltered in anyway when I was driving it sideways on that cliff we would've tumbled down onto these jagged spikes meant to trap vehicles that slide down this intentionally built choke point mountain pass thing. There is no other truck in the world that I could drive off a cliff and expect to live, I say the High Mobility Multi Wheeled Vehicle is the most reliable truck ever built.

Ethan, for future reference. There's a Humvee tour company in Moab, so they might have had the spares you needed. Most military vehicles are limited to 55 mph. So that's part of why they have a slow reputation. You also effectively had a fixed mechanical fan, with an un restricted flow, so not that much of a surprise that it wouldn't heat up.

[@ElevatedOverland]

We tried! They wouldn’t sell us anything

[@ericholley893]

I can't believe the crew was so weak Ethan carried this episode on his back good on you buddy at least the owner of the channel cares weak sauce boys not mint not premium subpar

Those machines at the begining are used in mining operations for moving large amounts of raw material underground. Dump trucks are quite tall, so those are used in smaller passageways

[@niksonrex88]

Cool stuff, thanks for the info man!

[@P373RV2]

First one! Yeah

This was really good blog about your buying and repairing these Humvees. The U.S. abandoned hundreds of them when they hurriedly evacuated Camp Bastion in Kabul, Afghanistan.

I know this was filmed months ago and it's probably the wrong time to tell you (this is more for the HMMWV owners watching this like me), I'm a SSG and Army maintenance technician. I've worked on these since 2008. At one point I can see that one of your return hoses is routed under the air-cleaner. For some reason, that's a simple thing that'll keep you from bleeding out the air. On the driver's side, behind that gold cylinder by the washer reservoir, there's a "time delay module". If you yank that, the rad fan runs full-tits. It'll rob power and kill gas mileage, but it'll get you home. The TDM powers that gold solenoid, that sends pressure to the fan-clutch allow it to free-spin. Without it, the fan is locked ON. Also, when I fill these cooling systems, I always just fill the reservoir, and manually squeeze the upper and lower radiator hoses to move the water around the system. When it gets up to temp, the air from the behind the thermostat and the top of the radiator should bleed out on their own. The AM General BDAR book will tell you to take two needle-nose pliers and crush the accordion on either side of the punctured pipe in the radiator, rip it in half at the puncture and roll the ends tightly. Take off the upper radiator hose put your hammer handle against the thermostat and BONK it to keep it open. All this will limp you to the next town. And never EVER use the throttle lock as a cruise control because it isn't connected to the brake. I love these videos and hope to see more of the HMMWV in the future. Might just have to go out and get one of my own. You guys make the best content on the internet.

Ethan, I moved from Kansas to Utah in 2014 and took a day extra on my way out in my little car and the pictures around St. George bring back so many memories of that trip in particular, but also of bringing the 69 K10 I bought in UT down there once, as well! Thanks!

[@romanihzer4667]

The Armored/fully geared crew ones are slow and heavy AF. Brakes on streets are sketchy. 45 on dirt roads make that baby rattle and shake like you're re-entering Earth's Atmosphere. But splice in a head phone jack to the comms and it's all vibes. Love this video 10/10

[@daniloborja9572]

Watching this man for many months I was always waiting and checking updates everyday for new videos..

[@Arithryka]

2:28 "ol' faithful, she's a-runnin' like a champ! we've come to an agreement, this machine and I, we're makin' it home." getting big Dustin from Destination Adventure vibes with this line 😁 16:50 oh lord

[@Sentrme]

Crazy that your entire trip has been the area of my life story. Pretty fun recognizing the locations. Glad you made it! Southern Cali - Vegas - St George - Moab - I-15 - Rexburg(St Anthony Sand dunes).

[@Hobbies4Hire]

Great job on the video folks! Thanks for making it. Loving the soundtrack for this series.

[@lyinarbaeldeth2456]

Good to see an old Humvee frolicking in its native environment (offroad). That thing *ate* all the rough terrain you threw it at!

[@number1yota]

Fun fact, the center is so wide, so that a stretcher can slide in the middle.

[@bullittdog4352]

Awesome content..the brothers seemed like super cool dudes..maybe they need to relocate north a bit?

[@nokbeen3654]

One of the best filmed and edited videos you’ve made so far!

[@PNWSV]

When I was a fleet mechanic we wouldn't even work on the 6.2 and if a customer had a 6.5 they would have to sign a waiver before we touched it. I've probably installed 2 dozen reman 6.2's over the years. Can't imagine how much of our tax money went towards repairs on humvees since 1983

[@pendragon6207]

Brilliant finale to the humvee challenge! ^^ Loved very minute of it.

[@Zericef]

If you ever have any questions about the Humvee you cant answer yourself, let me know brother. This series is awesome and I can't wait to see what else you do woth the truck. I was born in an AM General family and now work on these Humvees everyday out in Japan. They have their quirks but a well maintained Humvee can be very reliable.
