Nice work, and good job! To do something like this AND film it (quite well, by the way) is a huge undertaking. And you're not even swearing... I would've been cussing the whole time! Very classy; much appreciated.
Hahaha thank you very much!
Dude, thanks a lot i just replaced the heater on my A4B5 but i wouldn't have done it without your video🤝thanks from the Czech Republic
Love your content man. We need more Audi guys. Honestly, I feel like you left us hangin’ on the single turbo build. It’s all the little details I was after.
On my Allroad, the heater core pops out from under the dash. I am so thankful for that. That was one of my first jobs I tackled.
Thanks man! I’ll have a lot more content coming soon on the single turbo build so no worries. And you’re lucky you have an access... they should have put one on all the cars lol
Bro....that is ALOT of work, Great job man!
Lmao yeah it’s a pain! Thanks!
You sir are a life saver!!! With your video I did my heater core replace on a 01 A4 Avant in a day and a half. Without your through video I would have been lost. Thank You...Thank you!!!
Great to hear!
No you have a normal a4
Все что я видел о снятии радиатора печки, это снятие самой печки, без перемещения торпеды. Думаю вы сделали это лучше, добравшись до самого радиатора. Мне показалось что много демонтировано лишнего, что касается проводов тоннеля , шахты ауди разъемов, но смотреть одно , а делать там виднее. ОТЛИЧНО ЧТО ТОРПЕДА ОТОДВИНУЛАСЬ ТАК ДАЛЕКО и радиатор просто вышел под руки. Большое спасибо, жена удивленно смотрела на меня , не понимая как я смотрел не зная языка)).Но и так все было понятно.
As a b5 owner I love your videos there are barely any good videos of the car keep up the good work
I appreciate that!
Facts! Alot of videos suck on the B5S4 on the tube especially that sniper Bob fuck
Miguel Martinez Who’s that lol
@@CIPGAS hes some mechanic that has videos on UA-cam. Pretty sure if you type in the search bar snyper Bob b5s4 his videos will come up. But personally I don't like his videos at all! The quality is horrible, he plays that shitty music and the music is louder then his voice so its hard to hear him talk and he doesn't go in depth like how you do.
Well thanks for supporting this channel and I just saw one of his videos and I definitely understand what you mean now
Thank you so much for this. The old write ups on AZ and other forums are completely useless these days with all the pictures not loading etc.
Yeah haha I struggled with that at first and it's what led me to make the video
Watching this and everything is exactly the same on my except for the passenger side. Really helping me out. Thanks for one of the most detailed replacement videos I've ever seen.
Glad it helped!
I'm glad you did this I have been postponing this for 3 years and I live in Canada no heat in the winter has been challenging but u just gave me hope
I used your excellent and thorough tutorial to replace the heater core in my b5.5 Passat. You saved me big bucks! My cost was under under $250 for new core & evac/recharge a.c. Indie shop quoted $1300
Thank You and God bless!
Great to hear!
15:23 atta kid, momma and daddy taught you right 🔥. Forreal though, you’re making this process so much easier for me! Thank you sir! Your a legend! Great video, and great job showing before and after of removal of each part. That really helped me a lot!
Happy to help!
Thank u for the best s4 b5 Chanel .. i bought mine s4 b5 in 2006. . U made me got intrested för her again. My s4 stånd still for 8 years now. Nagaro blue in Sweden.
Thank you!! Happy to help bring another b5 back
Yo thanks for this video just did the heater core swap in about 4 hours after work. 💪🏻
Best walkthrough I’ve seen. Thank you Sir.
Glad it was helpful!
I love your passion and your calm demeanor! I have a 92 Audi UrS4 to take apart and replace the heater core! I'll try my best to as calm and steady as you are! Great video!
Thank you!!! Best of luck with the URS4 amazing car
You have to, I've done engine swaps, and even converted an A4 from an auto to a manual. If you aren't calm doing this stuff you'll be ready for a triple bypass heart surgery afterwards 🙃
I have an 05 B5 V6 Passat. I've done my brakes, timing kit, shocks struts and coils, but I'm really dreading having to change out my clogged heater core.
Excellently detailed and well explained video. Thanks.
It does suck but it’s not as terrible as everyone makes it sound. And definitely worth it once done.
@@CIPGAS I've been putting it off for 6 years. I backflush it every year but the "fix" is temporary at best. Thankfully I have a second vehicle to get me through the cold Connecticut winter. I'll definitely reference this video when I tackle it this upcoming spring. Again, thanks for posting this.
Thanks for this video man, this is going to be a huge help when I do mine here before winter. Just bought an 01 S4 and the heater core is bypassed so I’m guessing it leaks. I appreciate all the detail on every step, that’s what makes this video so much better than the few other ones out there!
Happy to help!
Goated tutorial, should mostly apply to my B6 s4 too
Thanks! should be just about the same. Good luck with it!
Got rear ended at a stop sign, hard enough to crack a lil paint on my rear bumper but it cracked the in and out plastic lines on the heater core. Great video thanks!
Wow sorry to hear about that. And thanks!
This is helpful.Very well documented.
Awesome job, awesome video! Love these types of videos, I need to tackle my heater core but been putting it off as I thought it was too much but after watching your video it’s not too bad! Keep vlogging 🤙🤙🤙
Awesome video content, both my b5s had weak heater cores that I always backflushed to salvage some heat. This video just gave me the tedious courage to go after it and replace the dam part already.
Best of luck man!!!
You are good mechanic with a calm demeanor, articulate commentary too. I appreciate your videos.
Hats off to you man, great job. I am a mechanic and I hate dealing with Audis heater core replacement.
Thanks man!
Definitely the worst job I’ve done on the car haha
My guy, after watching your videos I’m getting motivated again to finish my c5A6 build
Let’s get it done!!!
Thanks a lot for this video Brodie
Wow, very nice video! Glad your channel randomly popped up in my home page. By the way, a word of advice for anyone doing this work. Make sure you get the VW Passat B5.5 heater core. It is a direct fit, no mods needed, and has the METAL feed and return tubes, not the plastic ones our cars have. The inner core apparently has slightly larger diameter pipes as well (have not confirmed this, just rumor).
Also one final tip, you may need to "burp" the new heater core. Remove the return line, and start the car and run the heat at full blast. As the engine comes up to temperature, you will see little squirts of coolant and then it will start gushing out. Put the return line back on, clamp it down, and you got full heat again. Some say this is not needed, and it probably isn't. That hasn't been the case with me. I had to burp the system.
Other than that, EXCELLENT video, and great work chief. By far one of the cleanest and well captured process. Between you and Justin Ballou, great content.
Thanks! And great advice
You're a brave man, well done !
Hahahaha it had to be done!
Great job, great video! Hard to find good Audio maintenance instructions out there.
Thanks for this very useful video. I am building up to replacing the A/C evaporator and will also replace the heater core at the same time. Seems silly not to as it is a cheap part and most of the 'investment' is in time to expose it.. I have read an instructional blog that describes it as 'the good news is that you only have to remove two screws to replace the heater core, the bad news is that it will take you 6 hours to get to those screws'. How true but we love it right.
I've got a 96 A4 Quattro, heat quit working last year, and I believe that the blower motor went right after the hot air quit blowing. (Those lil LCD screens on the pre-facelift B5s heat/ac unit don't work lol) I'll be replacing the heater core, blower motor, and (hopefully, if I can find one that still works) the heat/ac controller unit. I've already torn apart much of the dash in the center, and on the passenger side. I was hopeful that it wasn't necessary to remove all the connectors, but it's looking like I'm going to have no choice. Tedious, as you so eloquently put😂🤣. I thank you for your detailed and thorough video, will probably be religiously watching it on repeat as I continue my dash teardown. Also, rewiring my entire audio system while I'm there(which was the original reason for the teardown, but I figured, why not get my heat back too lol). I've used your videos to help me do the brakes, replacing all the front control arms and outer tie rods, and doing my coilovers upgrade(I went with Raceland, on a budget lol). I will most definitely be using your tutorials in the future, and I look forward to seeing what more you do to your S4
Hello from South Africa 🇿🇦🇿🇦, at 14:26. I've got a '96 B5 V6 that I love. I've been enjoying your material man. Keep it going.
Thanks!
This is my dream build, and ten years from now when I'm finally ready I'll be coming back to your channel to find out how the hell to do what I wanna do. You are a genius, and I hope one day to have all of the knowledge and understanding of this stuff you have.
Thanks man!! I appreciate that.
I finally know how to delete my wipers, thank you 😊
Lol! 👍
Outstanding video! Just completed my B5 A4 by watching every step in your video. Again, many thanks for making this video.
Glad it helped!
Alright mate, cheers for this vid just used it to change the heater on my B5 S4 👍
Glad it helped
Great video!!! Thank you!!
Thank you love the video very helpful and informative
Happy to help!
great video. I did this on a B5 Passat and a VW Beetle. PITA
The fact that you have to remove parts basically in the backseat to do the heater core is ridiculous. Thanks Audi. This video is giving me anxiety now dreading when the day comes to do my heater core. Lol.
Definitely a huge pain, I’d rather pull the motor a few times than do a heater core
Well done sir.
I have yet to do mine. Flushing it worked for me but one day.....
I like the way you did this.👍🏾
And I see you got the wife to help.😁
Thanks man! And yeah lol I needed all hands on deck for this one 😂
Cre8tive garage here showing love keep up the hard work we stopping by from Las Vegas 🏎👋
We love the channel vibes 🥂
Thanks man!!!
I noticed you sealed around the cabin air filter just welded in new metal and a shit load of seam sealer to make mine water proof.
GOAT!!!!!!! I’m worried I’m gonna have to do this soon… foggy windows, and heat that’s.. lacking, all of a sudden. Coolant doesn’t seem to be dropping.. gonna try bleed and flush (again) first of course
Thanks!! Do whatever you can to not do this 😂. Hopefully a flush will take care of it
Good job guys
Thanks!
great videos. keep them coming!!!!!!!!!! subscribed.
Thanks, I’ll make sure to keep them going.
Thanks for the video ! helped me. there was 2 bolts i didnt see and was happy for your video. alldata tells you to take it all apart in pieces, glad i didnt !
Happy to help!
Hey bud, your a mf'ing champ I've been worried about this job for a year... alot less now!! Still a "B" I know but you have the best video of the heater core job on a AUDI B5 that's out there.. thanks bro
I appreciate that! Happy to help man.
nice video . thanks
The A4 I bought already had a new heater core installed from a VW specialist shop from the previous owner. Watching this for morbid curiosity of what I lucked out of doing lol
Definitely lucked out, it sucks lol
Ooof. Looks like not a lot of fun. I dismantled a B5 passat for an engine swap and I honestly never want to have to take the dash off. Kudos for getting it done in a day.
Definitely a pain man!! Thanks!
Thanks for confirming how much work I have to put into removing my dashboard…. 😂 Liked and Subscribed.
Thanks and yeah man it’s a lot!
Thank you, another great video👌. So maybe some day, if I have to do that job too, your video defenitely would be a big help to me. I'm not afraid anymore 😅
But at the moment all still works fine on mine...👐
I hope you never have to do it haha. It does suck but having heat is a great motivator
I have a b5 A4 1.6L and I've found a parts car with a 1.8T engine on it. I want to do an engine swap and an interior swap because the donor car has a leather interior and mine is in bad condition too so basically i will have to remove everything. I do work as a mechanic for about a year but i have little experience with interior parts so wish me luck. Ill save this video for that day.
Best of luck! Not a difficult job, just incredibly tedious.
Good lord.. I think I will elbow mine off for now LOL. Thanks for the detailed video bredda
Lololol can’t blame you
I saw your heater core that and I thought you would not replace it. But New Jersey (i think you’re living there) is cold in winter you definitely need to replace it. Nice video
Yeah I’m in NJ way too cold here to buy have any heat. Thanks man!
Good job
i like it
thank you
I'm glad you liked it.
you're an angel of God. Thank you for this video.
Happy to help!
Thanks for this video. I am looking at doing a A4 B5 2.4 V6 here in NZ which is soon to be summer. No drips but coolant fuming up into windscreen. I assume all cars you can pull forward the dash. Instead of 10mm I found they are so far 8mm.
Welcome! And yeah it is is fogging up the windshield it is definitely leaking.
Someone want to remind me why I haven't replaced my heater core yet? Ohh that's right, you have the remove the entire dash.
I have vw passat which is basically the same what you have , i get what you done nicely, but unfortunately the steering rod it doesn’t come out after i take the 16mm nut, so what I have to do now, beside the torx bolt it doesn’t move at all
It might be a bit stuck. Try jerking the wheel side to side quickly
That should loosen it up.
Gerät job bro!
Thanks!
Nice. I've done a few only done two heater cores ever. One was a fox body other was my escort gt. The escort was a cake walk compared to this. Well I guess I'll be flushing my b5 s4's every fall like I been doing since 2012 then, lol. Mine was clogged when I bought it. Bought it in the summer, owner pulled a good one on me. This car had radiator stop leak in it I think that clogged it. But many owners have this issue for some reason. Not sure what's the issue with the B5s? Small orifices in there I don't know. My 01 B5 A4 thankfully is good.
What's your take on doing a coolant filter on the car?
Also if you ever feel like it make a video about lining of bumpers up all nicey-nice. Both my bumpers are all jacked up. The height adjustment on my front bumper supports does not work
Damn stop leak! I hate when people do shot like that. Also I have never heard of a coolant filter but I don’t think it would be a bad idea as long as flow is restricted to much. The passage ways/orifices in the core are very small in order to fit more of them on the core for better performance but that is what leads to all the clogging and then leaking.
And sadly I might not be your best bet for a video on lining up bumpers. My car has had quick disconnects on it for a while now.
Great job man 😍 what s tye size of the L pipe ? I will have to so that before aswell , bit cold in the uk right now to change the heater outside 😅🤣 thanks in advance
Hallo. Thanks for the video! Grate job! Can you tel if its posible to remove just the uper side dasboard?? I need to do tapestry repair on uper part. Thanks a lot! Greate video!
Unfortunately not you have to remove the whole thing.
mannn i was just about to buy a cheap 01 s4 6spd but heater core needs replaced after watching this yea im good lol
Great Video!! I have 01 b5 A4 2.8L. The heater and AC don't really blow out a little heat and cold. There is a little heat but not much. It's irritating. No codes. Instead of replacing the heater core like you. Is there a way to clean it?
Thanks! You can try to flush the core with water. Connect a hose on both sides of the heater core and using a pump in a bucket flow water to the core to flush out any buildup.
No need to unscrew passenger airbag bolts, in addition I removed front driver ABS sensor connector.
I am about to attempt this, for different reasons.. short story, totaled my b5, got a slick top chassis for free and it has wiring issues. I want to swap my entire dash to the new (to me) chassis. My question is, can I go ahead and pull the dash out following the way you did this? Thanks a ton in advance! Your engine pull video saved my ass three years ago now!
I need help i need to replace the herater core i have a audi a4 2001 2.8 i díd evrething that u said but the driver side is not móving
thx for the video 4uattros! i’m stoked i found your channel, and this video literally has given me the push i needed to get this project started...
i’m not in nj, but the bay area gets plenty cold to need heat!!
i bought the car with the core already bypassed... my question for you is what core did you end up buying? i’ve seen a bunch of aftermarket ones in the $50 range, and then of course the oem is up around $300... i’d love to go with the cheaper, i just don’t want to have to
do this again... thx again for your help!
If you never want to do it again they sell a core that is originally from the Passat and is all metal and leak proof. I went with a 50 aftermarket replacement.
4uattros4 and... how’s it holding up? any leaks or issues?
@@spree2x All good so far
I replaced my S4’s heater core recently with a mechanic friend (used this dash pull method). Original BEHR core was not leaking but was very clogged/useless. Decided on the Nissens core for the replacement. It is the plastic end tank design, but Nissens is a very reputable brand and makes a quality product for sure. Considered the all-metal Passat core, but they apparently only put out about 80% of the heat of the quality plastic end tank versions. Sourced the Nissens through Worldpac for about $115. I believe they are available on eBay as well. 3 weeks later and the heat is better than ever. Great heat output even before the coolant temp gauge comes off the peg.
PS be careful not to crack your windshield while swapping the cores out. There isn’t much space to slide it out, we ended up taking the steering wheel off to be able to tilt the dash and get more space. Also, move your seats all the way back and tilt the front all the way down right away before the battery is disconnected and everything is unplugged. You’ll thank yourself later when you need the extra space. This was less of an issue for him because of his lower aftermarket seats.
Nice video hope I never have to do this ever
Lmao I hope you don’t have to either.
Is there enough room to leave the steering stuff connected? Unless I missed that you didn’t disconnect the column or anything right?
I did have to disconnect the column under the dash. If you don’t disconnect it you won’t be able to pull the dash.
Congrats !!! You are very patient. That's too much work to replace a heater core. Very bad design Audi Engineers.
Yeah they definitely did not make it easy
Just curious you would know about how to solve the heater core hose lines that leak? Without buying the lines. Any diy to fix it the return line it is eta which i need?
Do you know where the line is leaking? Near the heater core or on the crossover pipe? Most likely will need to replace it
@@CIPGAS its the return line leaking at the plastic fitting on the engine kinda sucks that there are no aftermarket ones
Just beware when doing this job make sure too double check all those connectors underneath, I had two yellow plugs on right side found them swapped and my car wouldn’t start and ECM no communication to ECM, had too recheck everything found the issue not I got it working after I swap those connectors just FYI if anybody gets no start no communication. Thank you for the walk though
T70 is my largest. It is a subaru diff plug socket
That’s obnoxiously big lol
Considering amount of needed work there are either 3 ways.
1. Go to mechanic and pay a lot of money. What is most likely to happen is that something will be damaged on the way through and you won't be able to prove that it worked before.
2. Do it yourself - waste a lot of time, got very mad and also probably damage something what will make you double angry.
3. Scrap the shit.
Lmao!! Go for 3
I dropped the HVAC box when i did mine took me 12 hours cuz i had no idea what i was doing 😂😂😂
Ouch! 12 hours is rough man!
But it was all a learning process because ive never removed a dash out of a car or center console. Im still new to the auto industry so im still learning more about cars and how to work on them.so because of it being a learning experience thats why it took me a while.
Wiper arm cap OEM 5N09552059B9 .. keep up the good work .. all the best from Slovenia
Thank you! You’re the man!
Can u reach the a/c evaporator as well like these?
Yes you can
Hey man i have an 1999 Audi A4 avant. Do I have to keep the steering wheel column straight while doing the heater core?please help thanks
You don’t have to
It just has to go back in the same orientation
Hey bro I also want to take my seats and carpet out. Is it easy to do? Do I have to disable the air bag system ? Thanks for your help!
Can you share details on your radio and its faceplate?.... awesome video BTW thanks a lot
Thanks man. I run a super cheap Atoto radio with Apple CarPlay built in and a Metra install kit which includes the faceplate and fits perfectly. everything is also wrapped in alu look vinyl
if i have to do this now because i watched you do it ima be pissed LMFAO !!! great work man hell yuh get that thing mobbin !
Lmao! Hopefully not.
what brand heater core did you use? was it OEM? How is it holding now?
I used a cheap aftermarket replacement and so far it’s held up great.

Hey buddy how do you use telephone in the Audi
Lol never have. Yeah that’s a great question
Bloody good job man, but why such a big job for such a simple part ai 😂
That is a very good question! 😂
is it the same process 1996 audi a4 b5? when I set it to high it is not hot, I think there is a problem mixing hot and cold. there is a sponge inside and after a long time it is simply burnt. That's why now it only keeps hot and mixes with cold air. Has anyone had this problem?
The process would be the same. And I ave not run into that.
How come you didn't use the all metal heater core? Aren't they supposed to last as long as the car will?
Yes lol they are. I didn’t know it existed till after the job. And it’s also $300. Plus I don’t drive the car often enough in the winter for this thing to go bd again lol.
Was your heater core clogged or had a crack? My dad was able to flush out his b5 a4 heater core before he sold it chunks came out
It was cracked, so I had to replace it.
@@CIPGAS ah rip i hope mine doesn't crack
Very good video man. I have a 2.6 litre audi a4 b5 and im about to tackle this job too, been putting it of for almost a year, now you got any pointers?😂🤘
Thank you! My best advice is to not be afraid when pulling the dashboard away, you will have some resistance to fight through.
@@CIPGAS okay, i will keep that in mind then, thank you som much!😁
F@ck sakes... Now I've gotta do this shit!
Damn, sorry to hear.
Well that fucking sucked! But can't really complain, no grease or being in the elements. Thank you thank you! I followed this video the entire time. My only issue is now my car won't start! I'm quite sure everything is plugged back in. But before I double check any thoughts? Would unplugging ECU cause a no start? Not even cranking. Have power but that's it.
My heater core is currently capped off also. Everytime I watch a video on how to replace it in my B5 S4, I have no interest in taking on the task. This method seems to be the most clear cut way of doing it though.
Yeah man it’s a crap job! But worth it in the end.
@@CIPGAS Are the keys for the stock radio removal the only special tools required to do this job outside of that used to evacuate the AC system?
@@jerryreid813 That’s right. All other tool are common garage/home tools
@@CIPGAS Thanks. I feel like I have to buy special tools every time I attempt to fix something on this vehicle.
Just replaced mine a couple weeks ago in 100 degrees weather. It was not fun 😭
Jeez man! Why do you need it if it’s 100?? 😂
donde puedo comprar el radiador
Europaparts.com
So basically if you have a POS A4 when the heater core fails sell it and get another POS A4 lol ;)
Hey bro couldn't help but notice how shiney and greasy your steering wheel is..... A quick fix to restore back to brand new is light work with a magic eraser and some water. Give it a try and lmk what you think!
Thanks man! I’ll give it a try
@@CIPGAS it'll make the feel better and the look better
Why do all those wires have to be disconnected???
So you do not stress the connectors and cause issues
"Extra hardware" = Weight Reductions Lol!
Lmao!
