Straight to the point, no bs, no story, and no beginner tutorial. I love it! Wish all technical videos were like yous
For anyone attempting this, I found an even easier way to pull the bolt behind the intake. A stubby socket wrench and short 10mm socket can get it off if you have a buddy around. Climb up in the bay and reach down over the intake to get that socket on the bolt. Once it’s on, keep a finger on it. Have your buddy crawl underneath and turn on it. You can barely reach, so it takes plenty of turns, but we made it happen this evening. 2014 Silverado.
Thank you so much!!!! Because of this video I was able to replace my evaporator core. You can replace it while keeping the heater core hoses attached so you don’t leak coolant everywhere. Just pull the whole ”hvac” system forward. Also I got up on my front end of my truck and reached my hand down behind the intake with a 10mm on a 1/4 ratchet and was able to remove that bolt. It sucked but I got it!!!
Dude! You are phenomenal at this! I wish every repair video was as clear and straightforward as this! Keep up the awesome work!
Just wanted to say thank you. I watched this video and it gave me the confidence to tackle this job. You saved me 3500 dollars. I was able to do this job by myself because of this video and ac was fixed and cooling better than ever. You had every single part in order and I can’t thank you enough. You have a new subscriber. By the way the ac system in this truck is the worst I have ever seen. Problem after problem.
This is a killer video dude, just turned a 15hr job into a 4hr one, thank you so much man.
God. So glad I got the extended warranty on my 14. I’m pretty sure this is the issue I’m having now. It’s going to the dealer next week
Was this your issue?
my guy you the truth , just did this job alone in 5 and a half hours ... got paid for 15 hours of labor. thanks
Great video! Thanks for showing the trick to get the bolt behind the intake. Knocking one out first thing in the morning tomorrow. I've gotten good at the Ford's but this'll be my first GM dash pull.
Video was spot on . I've done lots of dashboard work in my years in autobody (airbags) And your video saved me a lot of time , on my own truck .
However, for guys with a duramax , that one bolt behind the engine... plan on removing top half of the engine / all the exhaust / turbo pipes . To get to that one bolt. There is about a half an inch to work in , if u can find it.
Bro amazing concise video! A lot of viewers will be able to hammer a job like this thanks to you. Job well done.
Awesome video man definitely saved me hours this morning. The swivel trick for the bolt behind the intake wasn't working for me but I was able to get to it with a mini 1/4 flex ratchet incase anyone else is having trouble getting on that bolt
Did you go from the bottom? How did you get the ratchet on there?
Great explanation, I'm doing lifters and think I broke the heater core pipe driver side. Thank you for the video. 👍👍🏁🏁
Wow! Mad respect. I have no interest in tackling that job but I will give it to the dealer vs the generalist mechanic I usually use. Thank you.
15 hours! on what is essentially a new truck...May as well replace the Condenser while your at it.....Good job GM.
Good video. Good tech video. Felt like I was in the training center for a second.
I want to say thank you this video saves me 3800 hundred dollars and I did everything in 12 hours thanks again
Great video it helped me do a evaporator core in half the time! Thx for sharing and posting your experience and knowledge
Thank you so much, i have to pull one today at work.
Going to do one tomorrow. Thanks for making a video!
Thank you!!!! I needed a video for heater core and I couldn’t find any. You really helped a lot! Thanks!
Awesome video! Thought this set up looked familiar like an 08 Chevy. Better than alldata's disaster R&R it has me running through!
This is so helpful and straight to the point, thank you so much it looks like the issue is the compressor seal on mine and hopefully that's it, but if not I know either how to get at the EVAP core or to hunt you down for this job
I used to do jeeps this way in an hour. Jeep Chrysler audited the dealer and watched me diassemble one
I had the the heater box out in 20 mins. They were mind blown but it ended that audit quickly. LOL
Grand Cherokee model
And then they cut the time down. Ha ha
I can't use the proper adjectives to describe GM engineering on the replacement of heater and evaporator coils. They made this a nightmare starting back around the 2000 models.
Awesome video straight and to the point!!!!!!!!! Well done. This is going to help a lot of people, 🙌🙌🙌🙌👊
Thanks! So many videos have you watch an intro and then after that they ramble on and on about irrelevant stuff then video every single bolt they remove to give you a 30 minute video with only 5 minutes worth of actual useful information. Damnit all I want is the meat and potatoes!
Spot on thank you so much bro I hope you keep the videos coming one of the best if not the best I have used. Thank you again
Thanks bro!! And thank you for getting straight to the point!!! Other dudes say there life story as there removing a bolt… thanks
Yep I hate those videos. Give me just the meat and potatoes!
For anyone trying this I recommend taking the windshield off or calling a professional to take it off it’s way faster when your taking those 4-6 10 millimeter bolts & you don’t have to take the hvac box completely out meaning you don’t have to take the heater hose out & the other hose off just take off the 5 10 millimeter bolts and it should give you enough room and you can take the evaporator core out inside the vehicle. Also be careful when putting the evaporator cover back on don’t pull on the heater hose like I did bc it will snap and you’ll have to change that too. Hope this helps anyone.
Best video ever show. Thank you
The top housing is held by a couple torx bolts along with other black bolts that doesn’t seem like and Allen would fit in there. Is there a special tool for this? I just need to get those out and I’m finally at the evap core…
My dude you rock.
Turned this into gravey train brotha 👊🏽
Great video! You mentioned you used a scope. Is this how you confirmed the leak was coming from evaporator?
Amazing video, thank you for the details Tech Red! Anyone ever have a sweet smell coming in from vents or foul smelly wet sock odor like satan's breath was blowing at you when you first start up on a humid day? I am not talking about a slight smell, I am talking about a smell like something died in the system. After about 2 to 3 minutes, the odor clears out when turning on ac. I am curious as to whether something happened to the Evaporator Core when I bought it back in 2014. This has been happening every summer since. Chevy always wants to throw fresh spray in the system.
Leaking heater core will cause sweet smell. A dead rodent will cause the bad smell.
Thank you
Great Video!
Imagine if it was a Ford and you had to do all this to get to the cabin air filter 😂
Is this this same job on a 2016 Denali duramax? Wasn’t sure if there’s a difference between the 1500 and 2500
Great video and to the point.
OP can you tell me how you diagnosed it to the evaporator core? You said you got a scope in there? Thanks
Usually you can remove the blower motor resistor and use a borescope to get a good look at the evaporator core. Most leaks will leave behind a wet oil spot or in this case an UV leak detector dye that is visible with a special UV light borescope
Can the heater core be replaced without releasing the refrigerant and disconnecting the evap coil?
How’d you get the steering column to go in?
Going to watch the video tonight, got to do on a 18 silverado tomorrow. Have you done an air distribution case on a envision where the rear temp door is broken. I have done a few at the dealership not any fun
@@timothyrachford1868 nope, haven't even touched one of those cars yet!
@@TechnicianRed step 1 disconnect the battery, step 2 remove the front doors
@@timothyrachford1868 I heard some new GM models require windshield removal to gain access to hardware holding the dash in. I haven't actually seen that yet- just what I have heard.
@TechnicianRed I haven't had the pleasure of doing much interior work yet on the newer stuff, but know I really dislike the engineers that design them
quick question what kind of fasteners are they using for the top housing? its looks like there welded plastic do i just drill them out? and how do you reattach them?
This one had screws but some newer GM units are held together by melting the plastic case halves together (like a plastic "spot weld"). Unfortunately, I haven't had to repair those yet so I can't offer any great advice but I'm pretty sure you would drill them out and install screws with washers.
That’s what I do. Drill and find new screws to fit.
It must be a nightmare to put those bolts back in. I can see little bolts falling into crevices. Putting some masking tape on the head of a the bolt and stuffing it in the socket can help a little.
I use electrical tape to hold the bolt to the socket. It doesn't take much. Very easy to do with flange bolts/nuts. Just a 1/32" overlap under the flange holds good buy still allows easy socket removal.
Hello, where is located the evaporator temperature sensor in this truck?… should I perform all this disassemble procedure? Thank you in advance.
I have the Same Question !
Specialty tool needed for heater core hoses on my 2018
I just did a 17 this morning and didn't have that tool either. I wound up pulling the hoses through the firewall with the box since there was room
@@papacrunk5967 - fuel line disconnect doesnt work like in previous years?
No wonder why the dealer quoted me over $3k to check the evaporator core.
I have a leak in my 2018 sierra 1500. I’m wondering if what’s on your video will apply to my truck as well?? Dealer is charging me 4k to fix evaporator core. My jaw dropped when tech told me the price.
I just got the same quote today on my 2018, and was wondering the same thing
How’d you diagnose the evaporator core? Where’d you stick your scope?
Used A/C leak detection dye and my Snap-On borescope with the UV probe with dual cameras (one is at 90 degrees). I believe I went through the blower motor resistor hole.
How many hours did this take? Mitchell Labor Manual says 16 hours, this looks like less than that.
How would you know if your evaporator is starting to go out and needs replacement?
I told one of my buddies every-time i turn my ac on in my silverado it would blow the smell of wet cloths from the vents only for about a few seconds then itll go back to normal! He said it could be my evaporator thats giving out!
Any idea or suggestions where to start looking for the issue
If your evaporator is leaking enough to produce an odor, your a/c would allready be noticeably low on refrigerant. I can immediately tell by smell whether it is the evaporator or heater core leaking but I've had plenty of sniff tests to dial in my sniffer throughout my career. But to answer your question a borescope through the blower motor resistor cavity is the 1st step I take to verify a leak. Most leaks will leave an oil spot that is visible with the borescope. If you don't see anything put some UV leak detection dye in the system and recharge the A/C. When it gets low again, look for the leak with a UV flashlight and glasses. I have yet to have dye fail me!
@@TechnicianRed the leak test seems fairly easy And its not to expensive. I know my A/c isnt low since my air is still cold. However it blows hot with the wet smell only for couple seconds when i start up my AC after it starts blowing cold. I stoped at oriellys to get this spray to put in the outer vents to hopefully clear out the mildew or smell it worked for about a day hahah to no avail.
Thanks you for the tip!! Hopefully i can get the issue resolved b4 it becomes a bigger problem
@@mclovin_it8872 heater core
Hope some one can help me lol who had luck with getting the first driver side 10mm out cause I’ve tried everything from wrenches to swivel sockets
Why can't gm make it so the heater core has a access door to replace it instead of having to take the whole dash out to fix it
What things should I replace as long as the dash is out?
Heater core, evaporator core, evaporator temperature sensor, any hard-to-access air door actuators.
Do I have to take the front seats out to have enough room to pull the dash out?
The seats can stay in.
@@TechnicianRed thanks do I need to drain the coolant or it doesn’t matter?
Where do the transfer case pcm cables located
I don't know. They have to be located in one of the main electrical disconnects that I disconnected in the video.
U can cut a hole on the side and remove it that way it will save thousands, only thing you have to do is epoxy the piece you cut out
Can you give some more details about this ?
What is a estimated cost to have this done by a Chevy dealership?
15.1 hrs book time at approx $150/hr plus parts & R134a. About $3,000
Just got a quote for $3200 in Utah.
Gravy here I come
Is this the same for 2017 chevy silverado?
Yes
What are the risks for scratching plastics??
I have never had a problem and I have removed probably 150 dashes so far. Don't buy the plastic trim tools- they suck and usually cause more damage than a smooth metal trim tool.
Possibilitys of rattles after job done what a nightmare.
I've actually never had 1 rattle from doing a dash removal job and I have done many makes/models. So long as all the bolts go back in its really hard to mess it up.
did everything you said now my blower wont turn on
Check your blower motor resistor connector and go back over all the connectors that were unplugged behind the kick panels, etc.
I though about cleaning the evaporator, but I’ve decided against it.
I love my Tahoe and my Silverado but gm make big mistake on this
What’s stopping me from jerry rigging the evaporator core on the outside of the fire wall? there’s gotta be an easier way than all this junk
No offense but if you can't do what is in this video, there is absolutely no way you would be successful in relocating the evaporator core to the engine compartment. Not to mention what a terrible idea that would be...
@@TechnicianRedbuddy listen idk bout you but I’m a blue collar working man I can’t afford to pay a technician 2000 for all this. They said it’s a 15 hour job so unfortunately it’s something I’m going to have to take on myself. That’s me spending my weekends on it with my two kids begging me daddy please come play with me. So pardon me for trying to think of a shortcut.
That being said I do appreciate your video man. It’s the best one out there
