Adding an AC Evaporator to the LMTV

- I got an AC condenser form a source that would rather remain anonymous. However If I had to do this all over again I would probably just buy the complete kit from one of the online sellers that are available these days.

I used 5 of these
EATON Weatherhead 1469X6 Air Brake Tubing, 90 Degree Elbow, Male Elbow to Male Pipe Thread, 3/8" Tube OD, 1/4" Male Pipe Thread

1 of these for the supply line.
EATON Weatherhead 1471X6 Air Brake Tubing Male Run Tee, 3/8" Tube OD, 1/4" Male Pipe Thread

This is the Air line that I used.

I re-used the original fittings that were on the bulkhead so I needed new ferrels for the compression fittings.

This is a good thread on installing a complete AC setup in an LMTV www.steelsoldi...

This whole channel takes some work. Thank you for putting in that work.
Thanks for sharing your adventures
Your attention to detail is amazing. Great job.
Agree!!!
Thanks for the great video. I'm working with the diesel mechanics to install the same type of a/c unit in my Lmtv, and they've got questions I can't even imagine to begin answering. Thanks again!
Very hard work for you to fit in awkward positions while solving almost unsolvable problems. In a former life did you repair these vehicles. A welcome distraction from recent current events. Thank you! Stay safe.
I find myself saying exactly what you say moments before you say it.
Thanks for the video. Looking forward to seeing the others that complete the project.
They never cut holes for the drain on mine either. Another item to fix. No wonder I thought it was icing over. It did eventually spit from the vents though. Maybe they routed the drain another way and it's just over flowing. I'll have to check.
Great video you are an incredible resource
Sir, have learned much from your videos. Most importantly there are jobs I will have to pay someone to do..😂
When you painted this did you happen to take photos of the assembly? I really need to disassemble the evaporator to replace the expansion valve and thermostatic switch. At the moment it's looking like I will have to completely remove it. I rather avoid all the work you just did. Smart man, adding that conduit. Whoever installed mine made a mess off the wiring.
I looked. I don’t have clear video of the assembly. But you should be able to pull the bolts from underneath and lean it far enough forward to get your hand back there to run wire.
Were you in? When I retired the last thing on earth I would do would be to buy an LMTV or a deuce and a half. Doing good with everything just keep at it. Or buy an IWS. Enjoy!
My favorite quote from 2019
"This is one of those projects you ask yourself, 'Am I the right guy to be doing this?' Your answer, inevitably, is 'No, but I'm the dumb one so I'm gonna do it anyway.'"

very cool! thanks for sharing.
Your videos are so entertaining:)
New words that I learned today " Tract TORE" and "Trrrrrrrrr ailer"
Fun to watch best engineer
Isn't it nice to have fun at work lol😅
Where did you route the fan/compressor/pressure switch wires down through the floor? My harness comes in Tuesday, so I want to get that routed this week.
Thanks in advance!
There are grommets on either side of the engine tunnel. I ran them through the drivers side behind the accelerator pedal.
I purchased a 2003 M1078A1 in July of this year. My heater actually was didn't work and switched to the GEN 2 Heater/HVAC. I have installed it, but like everything you can get for these trucks, no directions. Your videos are great. I have the Orange Power Supply wire from that Heater Evaporator unit and black ground wire. I know the orange needs 24 volts. Where did you hook these 2 wires to?
The orange I ran a line to the 24v switched lug on the back of the breaker panel. The black I ran to the common ground strap on the bottom of the breaker panel (the strip with a ton of blade connectors on it)
Oh and since misery loves company, welcome to the LMTV owners club. :)
@@BrokeOverLand I appreciate the quick response. If it wasn't for you and several others online us newbies would be flying blind. I am always amazed everything I need ends up coming with no directions.
I want to do the same install. I have seen the entire "kit" online for more than $5k. Do you have a parts list and a list of resources to find these parts? Just don't want to spend an arm and a leg on this project... I know you advocate getting the kit but holy cow $$$... Any help would be appreciated. Also, awesome videos, I will be using them as reference as I move along with my build.... thank you Robert - Seattle, Wa
Most of the resources I know that had reasonable prices on A/C parts have dried up. I have heard others are selling full kits. But I haven’t spoken to any of them lately. I still need to get off my butt and dig up an ac pump lines and all that good stuff.
Yo Chadwick, I see you drill through-holes and such and you use grommets and that's great, but I never see you coat or prime the freshly drilled metal....is that something you edit out?
Alejandro Yanez I use a cheep primer. But yeah I should note that in the video.
Enjoying the videos.
Are the drain tubes just those duck bill drains?
How did you know how far forward to place your template?
yes they are the duckbill type, like the ones they use in the floor. I referenced the drain tube positions based on the bolt holes on the left a right of the unit as well as the refrigerant line locations. I'll see if I can post a downloadable template on the blog for this install. brokeoverland.com/f/air-conditioning-condenser
Did the duck bills come with the evaporator? If not, where did you get them?
D Craigslist they came with the evaporator.
Did the old bolt holes line up with the new ones?
Thanks for all of your help. Your videos are really helpful as well.
Goodbye wrench. lol
Yeah I think I'll stick to rolling windows down.
Hi there. Did you replace a boljoints? If you did, can you share a parts numbers?
Thanks.
I been through pulling the heater unit... it was not terribly fun.
Just curious... please let me know why you are going this route, and not say, a roof mounted all in one running on electrical power? I know there has to be some great reason. I am totally not knocking what you are doing... Lord knows I have done some stuff that I am sure leaves people scratching the head. Gonna be nice having AC, though!
Helicool's Helipad I’m planning on doing a roof rack that I can use as storage. So a roof mount would add too much height. Also after watching Sean’s video on the electric units. I think the best way is to go as “factory” as possible.
swapping units is very easy, 5 or 6 bolts from under cab depending on model.
What condenser did you select? Where did you buy it?
Thanks!
The condenser that I'm going to try. (haven't done the calculations yet) I picked up from eBay. www.ebay.com/itm/303180383637?ViewItem=&item=303180383637
When you did the air brake valves, what did you use for a sealant? i.e. teflon tape or Loctite red etc Thanks!
PTFE thread tape. It’s what I had on hand. You can use liquid tape but I don’t recommend red or blue loctite on plastic parts as it can cause the plastic to deteriorate and crack. Loctite does sell a super bond that is safe on plastics.
@@BrokeOverLand Ah, ok. I think there is a lot of confusion on this subject, particularly with the move from metal manifolds to composite. Composite does not like a nice torch on it to release red loctite lol. It doesn't help that loctite sells all sorts of sealants in the famous red bottle.
Spoke with Haldex this AM. These said pipe dope, no tape, no red loctite. There is a Loctite 545 for air lines, BUT it is only metal connections. The issue with tape is the potential for clogging with bits and pieces of tape.
Thanks for posting what you found. 👍
Great video , I bought a truck that the previous owner bought a AC kit . But he only installed the heater evaporator unit . I have come to understand that he did not drill the extra 2 weep drain holes at the front of the unit . So if you could do me a favor can measure your template and give me a couple of Reference points so I can drill the holes up through the bottom of the cab. That would save me the major effort of R&R of the heater evaporator unit .
I really would appreciate your help .
Thanks
I posted some pictures of my install of the condenser dryer and compressor on Facebook .
If I can help you in any way I'd be glad to do so .

Dave V I’ll measure it up tonight
Broke OverLand Thanks
@@davev4144 Look at page 2 in the PDF on this link. it's more accurate than anything I'm going to be able to pull from the template. if you need me to measure from locations under the truck let me know. I also uploaded the wiring diagrams to the LMTV MTV military trucks facebook files library. drive.google.com/file/d/17w4oQjH6_4LfA_JiNwbHaFjg5RCCIYcf/view?usp=sharing
@@BrokeOverLand I appreciate your help.
Thanks again.
Hi. Can I find u for install this for my LMTV?
Parts list please.
Do have a wiring diagram for that thing?
Oddly enough I do.
No lol I mean I need a wiring diagram for the gen 2 ac unit
Are you a member of the lmtv mtv military truck Facebook group? If so I posted them to the files section.
I’m on steel soldiers but I’ll check out Facebook. Thanks
Here I posted them up on google drive, drive.google.com/drive/folders/134M1sbVKdpuZ6UfN2v4sVGcegBFD_pbb?usp=sharing
IF you still have your heater and want to sell it... I may be interested
spankybear it is just sitting in the shelf collecting dust right now. So make an offer and pay shipping and it’s yours.
@@BrokeOverLand I do believe you said you're in Western Washington in one of your vids. I am in Snohomish County. If there's a chance to do a face to face that means I can could make a higher cash offer. My email is (my youtube name) at frontier.com. The shipping would be a... um... bear :)
spankybear sent you an email
I don't see a condenser being installed. That is the evaporator.
vasiliy petrohof 7 months and you are the first to call that out. :)
Thank you for the awesome video! We are going to be adding AC to our LMTV soon, right now we are doing performance mods (new exhaust manifold, turbo, ECM and a new mapping program. th-cam.com/video/1IQVskTl4Xk/w-d-xo.html&ab_channel=ShaneDean Here is a vid of it, you are doing some great stuff and your videos are great! I need to record more of what we do. Thanks again for your videos, they really do help!
definitely record it. it is super nice to be able to go back and watch what you've done to remind yourself what you where thinking. #LMTVDrifting :)
