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
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.
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.
@@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.
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.

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.
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 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.
@@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.
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.
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.
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
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.
Props to Ethan for insisting on changing one factor at a time. Its the only way to narrow down the true cause. Edit: Duh, of course, Ethan, not Nathan.
I was a mechanic for the Army an on those trucks we had issues of overheating but we found if we disconnected the time delay it would stop overheating its a plug near a brass sylinder by the windshield washer tank.
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.
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 .
Humvees are totally underrated! I have a 1995 GMV (the special forces modified version with the Rod Hall suspension) and I find it perfect, just the way it is. The power is adequate for what it needs to do and there is no reason to change it!
Ethan I am glad you took it upon yourself to do this, and not left it with the other one for another series down the road with the group. For me, I would personally love to see you fix it up, full tear down, bring it back to its prime.
you somehow find the most positive people that no matter what situation you run into no one see's the downsides and thats what keeps me coming back to each new upload
I love this if I had a bunch of friends that were willing to spend day after day night after night with me for a couple of vehicles to take home for a road trip, I totally would
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. We always unplugged our trucks cause they always went bad and would default to the lowest fan speed. It's located right next to the windshield washer pump, 4 wire plug. Might help your overheating issue if it gets unplugged.
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 really enjoy how you guys let other people help with filming, wrenching, and enjoy the fun. You guys haven’t let fame and popularity turn you into stuck-up anti-social people.

This series is just banger after banger! It feels like each video in the series is getting closer and closer to that feature film feel. Good work guys!
Everyone needs a bro like your boy Patrick/Padrick. Dude was just down for the ride. The crew should've stuck with Ethan on this one, but they all had a nail salon/manicure appointment to get to. lol

Padrick is fantastic for the channel, and also brings a bit of balance for Ethan. Grind hard would be even better if you get Padrick on board full time !!!
It made my day happier, it reminded me of the time I traveled from Belo Horizonte in Minas Gerais to Goiana in the state of Goias in a gol cht 1 liter engine but "tuned", so let's say it was the original 1.0 engine, it boiled and the head gasket blew and he had the pistons and liners exchanged for pistons and liners from version 1.6, this was the week before the trip, we left at 3 in the morning, and right away, we lost most of the electrical system, everything turned off, and The windows were half closed, so we got rain, cold wind, some rain that appears out of nowhere and then disappears in the same way, the GPS threw us in the wrong direction, 400 km in the wrong direction, my father was the only driver of the 4 of us, they were 14 hours on the road we stopped 4 times to refuel, but the engine was weak (it still is in fact), we couldn't go over 100 otherwise the car felt like it would fall apart because it was shaking so much, the suspension was all bad, and we did this modification in the engine but we didn't change the rest of the car, so if it idled it would turn off, like put in neutral engine die every time,even when it was hot we arrived in the city of goiana at 8pm or so, I still have this car today, it's very slow, but it continues to serve me wait I forgot some details this engine cht It's an acronym that compond high turbulence and is made by Ford and was bought by VW, you'll find it the Ford Escort, I'm almost sure, it's 50 hp 10 kg of torque The torque is straight and the torque is basically constant from 1200 rpm On the best day, it does 14 km\L on gasoline or 12km\L IF it's the ethanol model and on the trip we filled up 4 times because the fuel tank leak if was half full

This is awesome. Just powering on, finding solutions for problems, and not giving up... there's no way youre not making it home with that attitude. Greetings from Overseas!
I recognize the one brother from his channel where he turbos the 2.4, and puts it in that red toy. The drone work was amazing. This was my favorite part of the series. Well done!
Chopin bringing in the despair... damn that was powerful. And the north african tribal fusion kind of tune around the 30 minute mark... nice. You guys are digging up some quality tunes.
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.
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.
@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.
When I was 16, I had a Chevy K2500 that I bought super cheap (had been in a rollover). The driver window was plexiglass. I drove that thing for years with gorilla tape holding the window in the frame. It also had two Volkswagen windows JB welded onto plywood that replaced the rear window. This series has been very reminiscent of my experience as a teenager. lol
Your thermostat staying open actually can over heat your engine in long operation. The fluid doesn't stay in the radiator long enough to cool it down so we just bring in hot fluid into an already hot engine
you do understand the thermostat opens to let water in to the radiator? if its stuck open its just gonna have a hard time getting warm in the cold or staying warm in the extreme cold thats why they had to block some air flow to the radiator.
7@@CoreyBates-uy1qw No that's wrong it cycles so it gets warm enough in the small circuit. If the engine gets very hot the thermostat gets wide open to cool completely down over the big circle. Why would anybody think fast flowing water trough a cooler is not cooling good? The bigger the temp delta between air and water the better the cooler works. You guys drinking water from fraking sites?
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.
Moab reminds me of that other dude who tries to travel in (or on rather?) a mini (sic) jeep made in china or something.. to moab and back... need to check on his series if he made it any further :D
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.
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
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
In case yall need parts for the humvees. You could check out Midwest Military Equipment. Tried to comment links to their website earlier but TH-cam is being.... well.... TH-cam.
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.
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
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!
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.
get plastic drink bottle that will fit upside down into the coolant filler, cut the bottom out of it, poke a neat hole in it half way up the bottle. take of the hose that goes to the radiator from the filler and place somewhere higher than the filler, get a piece of hose to connect to the outlet you disconnected and put the other end into the hole you made on the side of the bottle, hold bottle in filler and top up bottle, keep doing so till bubble have stopped or slowed enouph

I was a mechanic for the Army an on those trucks we had issues of overheating but we found if we disconnected the time delay it would stop overheating its a plug near a brass sylinder by the windshield washer tank.
In Iraq we had hole cut in the hood and had extractor fans installed to suck the heat out. We would regularly run all day and never had issues
@@djblackruss I have seen that as well over there.
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.
Actually that was what I came to the comments to type in.
That guy you picked up is so chill. He seems like an awesome friend.
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 .
Humvees are totally underrated! I have a 1995 GMV (the special forces modified version with the Rod Hall suspension) and I find it perfect, just the way it is. The power is adequate for what it needs to do and there is no reason to change it!
Padric was my roommate for awhile when I lived out west, he's a insanely talented guy and it's sick to see him on Grind Hard!!!!
My stomach literally dropped when he jumped that rock and I'm not scared of heights AT ALL.
Same. For some reason, that gave me the heebie jeebies. 😬😬😬
standing on that overhang gave me more anxiety, you never know when those things might give.
He made it by like 2 inches
Ethan I am glad you took it upon yourself to do this, and not left it with the other one for another series down the road with the group.
For me, I would personally love to see you fix it up, full tear down, bring it back to its prime.
you somehow find the most positive people that no matter what situation you run into no one see's the downsides and thats what keeps me coming back to each new upload
Those two brothers are so dope, what amazing friends to have. They both always have great attitudes and are up for any adventure!
I love this if I had a bunch of friends that were willing to spend day after day night after night with me for a couple of vehicles to take home for a road trip, I totally would
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. We always unplugged our trucks cause they always went bad and would default to the lowest fan speed. It's located right next to the windshield washer pump, 4 wire plug. Might help your overheating issue if it gets unplugged.
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 really enjoy how you guys let other people help with filming, wrenching, and enjoy the fun. You guys haven’t let fame and popularity turn you into stuck-up anti-social people.
Ego is what kills community. That's why they've got such good friends. No big egos, just dudes that love mechanics and adventure
Oh Man! That 16:40 jump.... Ethan achieved his humvee goal in life and you can tell he doesn´t care anymore hahah
Man, some of those desert roads get apocalyptic. I'm from Virginia, born and raised, spent my whole life around this part of the East Coast, and the lack of greenery mixed with abandoned buildings gives me serious apocalyptic vibes.
Keep it up man, y'all put in some serious work to get this done!
Same here. In northern Appalachia all the abandoned stuff gets hidden by the greenery
My LOAWRD I didn't think a cinematic masterpiece was yet to come from this project, yet here we are. Edwin, PHENOMENAL edit on this one. It's perfect. The audio and the cuts and ALL of it. Ethan, your absolutely living your best life and I love it! Your crazy man, and in a good way!!
16:56 I'm sat in Cyprus chilling on my porch and even I'm stressing right now 😂
😅😅😅
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
Cool stuff, thanks for the info man!
I'm just going point it out, the B role of him complaining about the wipers was clearly after he was in Moab (it was clearly somewhere on I15 way north of Moab)
We need more Ethan, Padrick, and Nicolas! Dream team!!!
Good job for not giving up. The other should be bummed they missed out on an epic adventure!!!!
Hello from Vancouver Island 🇨🇦 Awesome content!!! The weekend is that much better when I get the notification there is a new video to watch!!! Can't wait for the next one!! Thanks for taking us along on your adventures!!
Awesome! Thank you!
Yo, fellow Vancouver Islander! Lots of us on the island love your content Grind Hard!
Vancouver Island sucks! Tell your friends!
Island boys
This is SUCH a great SERIES, you guys NEED to add Right Stuff gasket maker to you emergency gear I have used it to fix MORE coolant leaks and Damaged Radiators on the road in NO TIME and usually holds for Months or YEARS after
There's an awful lot of "we" going on in the voiceover for a bunch of guys who bailed on their homie.
There was Top Gear and Grand Tour era, now i think this channel might be the next thing.
awesome energy from the elevated overland guys! love em
Maintained and balanced by an experienced military driver, this truck NA M998 is unstoppable. Speaking from experience.
I have loved every single episode of this series so far. Epic stuff.
Friends we ALL WISH we had ❤
Ethan is literally the mad scientist. Brilliantly smart and wild at the same time lol
Ethans can do positive attitude inspires me to do better and not let things get to me
Great video guys👍
He made the cardinal sin of not zip tying random stuff instead of just tucking it. Harbor Freight sponsorship in jeopardy.
This series is just banger after banger!
It feels like each video in the series is getting closer and closer to that feature film feel. Good work guys!
Everyone needs a bro like your boy Patrick/Padrick. Dude was just down for the ride. The crew should've stuck with Ethan on this one, but they all had a nail salon/manicure appointment to get to. lol
Thanks 🫶🏼
Haha! Well said.
The editing on this video is professional to say the least, whoever is in charge of that is crushing it!
Old Faithful indeed!
Also Ethan ... you are a maniac! Skydiving is usually done with Parachutes!
Love your travel companion! He seems like a super mellow, positive dude. Rock on mellow positive dude! Rock on!
That hose is your fan clutch hose. Its hydraulic ran off the fancy brass on the driver fender.
Etans the type of guy that gives a full chested hug to friends and jumps over cliffs with deathly drops. That's a guy living like theres no tomorrow.
Also.. my hands are sweaty, please step away from the edge. :D
Padrick is fantastic for the channel, and also brings a bit of balance for Ethan. Grind hard would be even better if you get Padrick on board full time !!!
It made my day happier,
it reminded me of the time I traveled from Belo Horizonte in Minas Gerais to Goiana in the state of Goias
in a gol cht 1 liter engine but "tuned", so let's say it was the original 1.0 engine, it boiled and the head gasket blew and he had the pistons and liners exchanged for pistons and liners from version 1.6,
this was the week before the trip,
we left at 3 in the morning, and right away, we lost most of the electrical system, everything turned off, and The windows were half closed, so we got rain, cold wind, some rain that appears out of nowhere and then disappears in the same way, the GPS threw us in the wrong direction, 400 km in the wrong direction,
my father was the only driver of the 4 of us, they were 14 hours on the road we stopped 4 times to refuel, but the engine was weak (it still is in fact), we couldn't go over 100 otherwise the car felt like it would fall apart because it was shaking so much,
the suspension was all bad,
and we did this modification in the engine but we didn't change the rest of the car,
so if it idled it would turn off, like put in neutral engine die every time,even when it was hot
we arrived in the city of goiana at 8pm or so, I still have this car today, it's very slow, but it continues to serve me
wait I forgot some details
this engine cht
It's an acronym that compond high turbulence and is made by Ford and was bought by VW, you'll find it the Ford Escort, I'm almost sure,
it's 50 hp
10 kg of torque
The torque is straight and the torque is basically constant from 1200 rpm
On the best day, it does 14 km\L on gasoline or 12km\L IF it's the ethanol model and on the trip we filled up 4 times because the fuel tank leak if was half full
Best way to seal a rad, is to crimp the lines that are damaged on either side
Try and bid on a ambulance model they make a good camper conversion platform
I dig the Roadkill vibe to this one. The more Ethan content, the better. Whats the plan for the Humvees?
I had fun watching this knowing im not the only human to have fath in the unfathomable!! I can watch every episode / adventure knowing i cant think your next video tops the last , it always does ! You all complent each other and honestly the best energy/vibe of any entertainer on this platform and many others ,
Never had or know what people seen in a idol , but ive found mine in you Ethan ! You and all your friends give me so much joy in my life , thankyou for that
Hello from Brazil, that's good footage, thanks to bring yourself to these shenanigans 😅
Our pleasure!

this legitamatly needs to be on netflix, a series where they buy crazy crap and try and drive them home
@@Noahdea611 I mean, Roadkill literally does that every episode of you're looking for a show like that.

I recognize the one brother from his channel where he turbos the 2.4, and puts it in that red toy. The drone work was amazing. This was my favorite part of the series. Well done!
Dude, awesome to hear that! 🤘🏼
I really like your guys vlogs it's like a good episode of top gear ⚙️ 👌🏽 drive safe on that one. That's badass 👍🏽
Chopin bringing in the despair... damn that was powerful. And the north african tribal fusion kind of tune around the 30 minute mark... nice. You guys are digging up some quality tunes.
Well, Eaton, I see. I'm not the only one with Fairweather friends. Funny how the friends you see the last are the ones that have your back the most.
They are his employees.
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.
We tried! They wouldn’t sell us anything
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.
@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.
When I was 16, I had a Chevy K2500 that I bought super cheap (had been in a rollover). The driver window was plexiglass. I drove that thing for years with gorilla tape holding the window in the frame. It also had two Volkswagen windows JB welded onto plywood that replaced the rear window. This series has been very reminiscent of my experience as a teenager. lol
Hell yeah I love that you got to drive through the Gulch on your way to St George from Vegas. I love that drive.
It was stunning
I love how effortlessly goes offroading. Shows you what it was made for.
Your thermostat staying open actually can over heat your engine in long operation. The fluid doesn't stay in the radiator long enough to cool it down so we just bring in hot fluid into an already hot engine
What a BS
You don't understand a cooling system at all.
Correct no thermostat is the same
you do understand the thermostat opens to let water in to the radiator? if its stuck open its just gonna have a hard time getting warm in the cold or staying warm in the extreme cold thats why they had to block some air flow to the radiator.
Y’all do understand that the thermostat cycles to keep coolant in the radiator long enough to cool the coolant down right?
7@@CoreyBates-uy1qw
No that's wrong it cycles so it gets warm enough in the small circuit.
If the engine gets very hot the thermostat gets wide open to cool completely down over the big circle.
Why would anybody think fast flowing water trough a cooler is not cooling good?
The bigger the temp delta between air and water the better the cooler works.
You guys drinking water from fraking sites?
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.
I don't know why it keeps are overheating........ continues to drive it at 8500 rpm
Fun fact, the center is so wide, so that a stretcher can slide in the middle.
Moab reminds me of that other dude who tries to travel in (or on rather?) a mini (sic) jeep made in china or something.. to moab and back... need to check on his series if he made it any further :D
I forget his name, but that was so good!

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.

Keep watching, you might be surprised
@@GrindHardPlumbingCo Oh I will. I'm hooked on this series! You're not getting rid of me for some time.
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
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
You stuck with the mission to drive a Humvee to Sandpoint and turned the experience into a great video and an impressive victory. Way to go!
First one! Yeah
Second
Probably not. TH-cam takes a few mins after release to show views and likes
601 lol
So Proud Right Now
5,000 th yeah
In case yall need parts for the humvees. You could check out Midwest Military Equipment. Tried to comment links to their website earlier but TH-cam is being.... well.... TH-cam.
Quick Google search is all you need to find parts and accessories for the old war rigs.
I love seeing your channel unfold in our little area, very refreshing.
This video made a nice change of pace. Love the regular stuff, but road trips and trail fixes are a nice change!
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.
You guys have the best adventures, undoubtedly the best channel on TH-cam.
Thanks man!
I always appreciate you guys keeping your content family friendly! 😊🙂
I love that I live 30 minutes from these guys. Hoping to see them rolling thru cda soon.. love the channel!!!! Og follower
Good to see an old Humvee frolicking in its native environment (offroad). That thing *ate* all the rough terrain you threw it at!
You guys should make a tandem dirtbike! Like a tandem bicycle but with two dirt bikes put together 🔥
Awesome content..the brothers seemed like super cool dudes..maybe they need to relocate north a bit?
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
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!
Excellent editing, excellent content. Ethan's optimism is inspiring. Great job on this series fellas!!!!!👌👌👏👏👏👏
Ethan's perseverance is something to behold, and celebrated.
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.
Next to the windshield washer bottle is a four wire black plug, if you un plug the plug the fan will constantly run , it will disable the fan clutch
get plastic drink bottle that will fit upside down into the coolant filler, cut the bottom out of it, poke a neat hole in it half way up the bottle. take of the hose that goes to the radiator from the filler and place somewhere higher than the filler, get a piece of hose to connect to the outlet you disconnected and put the other end into the hole you made on the side of the bottle, hold bottle in filler and top up bottle, keep doing so till bubble have stopped or slowed enouph
