- I found the best to way to remove and replace the heater core in a Volkswagen B5 Passat. The first time I replace one it was very hard and frustrating, I dismantled the dash piece by piece in order to get to the heater core. I knew there had to be a better way, my second time I figured out a way to pull the entire dash out as an assembly and the removed the heater core from the back. I was able to do in about 4 hours!
I hope you enjoy my how to video on replacing the VW Passat heater core.

Metal ( No plastic Crap) 8D1-819-031-CVW heater Core amzn.to/2QRLDzr
The Audi A6 should be very similar. Engines 1.8 2.8 1.9 2.0
dec 2023 I swapped out A4 B5 using this procedure......a real blessing to get windscreen demister action back up and running...and heater comfy warm... happy days....I also dismantled air box ( not easy, some clips broke in process ) and aluminium tape to replace disintegrated black sponge on heater diverter flaps...no more sponge being blown into cabin
Great video and soundtrack helped a lot with calming anxiety about taking it on
Hey AutoTech guys. THANK YOU!!!! I finally got the courage to try this. Having seen a car assembled at the factory, the dash goes in in one piece so no surprise it comes out that way too. Before this job, I have tried flushing and reflushing -- after taking out the old core, I cut it in half and even with a flush a week ago, most of the core was still clogged. It's a fools errand to flush and expect it to be good as new. So, at my local VW mechanic's advice (Neil @ Ellis Automotive) I got the Nissen heater core. It does indeed take about 3 hours. Took me more because I flushed the entire system after. Some tips for others that might do this: 1. the steering knuckle is a torx50; the bolts in the fan box @ 0:58 do not need to come out; the bolt at 1:44 connects the brake/clutch pedals and is between them; the wires at 1:49 for the clutch safety switch can be mixed up as there are two of the 2 wire connectors (I made the mistake of reversing them so the car would only start if the clutch was not pressed, whoops). AutoTech, I can't thank you enough. Had I known it was this easy, I would have done this years ago. Total cost: $110 CDN for the Nissen Core; $80 to Searles Auto in Victoria to drain and recharge the refrigerant; $30 for VW Victoria for 4 litres of G12.
what model Nissan heater core? yr? part #? thank you
renn16v For my Passat B5.5, Nissens 70224 from Rockauto.com.
I got your response on my email. but I don't see it here, thank you
Rob and Les Mill/Termuende so all four bolts at 0:58 don’t need to come out or just the two on the right?
7 years later and as I am about to embark on same project....working outside, on my own, during British autumn/winter.......this has helped with confidence boost ! thankyou : )
4 years later but this method is awesome; I've done it the Bentley way and this is so much better. Instead of a weekend, it was about 6 hrs and I took my time. Thanks very much,
Geoff Duncanson that’s awesome! I have a ‘01 Audi A4 and the heat has just started to fade at idol or when heat is full blast ( I haven’t tried the flush) you figure this is the way to go? Im mostly worried about destroying my almost mint wood grain!!!???
I need to thank y'all personally, posting this video and showing people you talent saved me $1000 in repairs. Yall gave me the courage to do it myself and every bit your instruction helped me do this repair all by myself. Pretty empowering thanks fellas.
Stephen Kelley That's Awesome! Good Job!
I've been driving (1998 2.8L S4) with just heated seats in the winter for 6 years because every mechanic says it's a huge job. Roomate is a VW mastertech and said this is possible. I'm going to tackle this with him before this winter. I really don't want to get rid of this car!! I just know realistically that the next $1000+ job will mean the end... almost 200k miles, everything is still in great shape. Just not safe in the winter if you cant see :(
Thank you so much! I have been with out heat for 3 winters and one of them we had temps with highs below 0 for 60 days straight! I have been dreading this project because it seemed so daunting with having to remove the steering wheel airbag, the steering wheel, radio, climate controls and everything else involved without having detailed instructions. Your video gave me the courage to tackle this project. Your video was near perfect; there was just one extra wire I had to disconnect near all the red wires connected to the 30 terminals. Thank you for making my winter commutes warm and toasty, again!
Bryan Watson Hey Brian, so you were able to go three years with a broken heat core? Did you have to fill the car with coolant or water constantly?
Lisa He you can actually bypass the heater core and recycle the coolant
THANK YOU! I did this in 5 hours compared to the 7 hours I was quoted from shops. 900 bucks to install a $25 part! NO THANKS!! Something to keep in mind for all newer vehicles as I understand most of them are built this way these days.... Thanks 1000 times again!
+Portalnator Back from the dead Your welcome - Happy to help!
could I used this for a 2001 Volkswagen Passat station wagon with a 2.8 liter V6 engine?
could I used this for a 2001 Volkswagen Passat station wagon with a 2.8 liter V6 engine?
+MrTeatreeoil Yes your car should be very similar!
+AutoTech mechanic's greed, they want $1000 in labor now that's bull shit
I have to do this job on my 02 passat, i was dreading doing the job piece by piece . Thank you for posting this great time saver, Now wont be afraid to sell the job at my auto shop
snoopmax1965 Awesome let me know how it goes!
This is an excellent video and I take my hat off to you. I have sold a Golf Gti mk 2, a Seat Alhambra and another Golf GTi mk 3 ALL because the heaters started to blow cooler after about 8 years old. I knew it was the heater matrix getting clogged with sh$t over time. And, I knew it would be expensive to rip the dash out, especially in the Alhambra which is about 3 feet deep! I did ask my VW service chap about it and he said "Sell, sell, sell"!
Superb stuff. I just did mine with the help of this video and another one. Altogether took me about 5 hours on a RHD diesel. Mine is in really good condition and I intend keeping it for a long time and this also gave me the chance to replace or fix broken bits of trim and loose wiring.
Nice work!
Thank you so much for this!!!! Book time is 10.2hrs on this and I was able to get it completely done in about 5hrs!!!
Did mine 2 hrs flat
I've done many passat heater cores, and I did them by taking piece by piece out. I was able to do them in about 6-7 hrs. I tried it your way and I cant believe how simple it is. I now can do them in 2-3 hrs!!! great time saver and great video!! Thank you!
Awesome! I hope you work flat-rate if not you need a raise!
AutoTech I got it down to about an hour now. I think we charge 8.4 hrs and I can do it in about 1 hr. It's awesome! But I can paid by the hour and not flat rate.
holy shit come to charlotte and do it for me, ill pay you $200 and a case of beer lol
You got it!!! I could use a road trip!
lol! I'm about to start it now. just dreading it, it probably won't be too bad. id rather pull the trans or the head than do this
I used this technique on my 2001 Audi A4 2.8l Quattro
I can't thank you enough
You saved me many hours
louis brugnatelli hey! I see this OSs an old vid/comment but if you get notified; .... I have a ‘01 A4 2.8l with 168,000 on her, the heart has just started to fade (at low rpm/idol) I haven’t tried a flush yet but I’m going to this weekend 🤞🏼 I am not a mechanic I am Journeyman fab/welder though with quite about of mechanical experience mostly in motors and mechanical stuff. Taking the hole dash apart is a bit intimidating (especially since all the ‘wood’ rim is getting very brittle and the interior is in mint condition I don’t wanna f-it up... is this the better option of a guy that has never had the interior apart in your opinion? Really don’t want to pay $1500 for a $80 part!!!
Hopefully you see this! Thanks for a reply if you do!
🇨🇦
Thanks for making the heater core video it was very helpful and much easier than the procedure in the Haynes manual
+dano521 Thanks For Watching!
Yup super fast and easy we was shocked of how tremendously easy this was got it in and out in 30 seconds the whole job took us about 12 seconds Thanks!!
My friend and I replaced heater core in 2003 Passat, 1.8. What an experience! We did it all by watching UA-cam videos. I have no intentions of doing another but I would try your way in a heartbeat.
Well done! Took me and a buddy about 5 hours to do this! Might start buying passats with blown cores 😂
Excellent instructions. you need to remove the black and yellow wire from the left terminal also. Thanks for the help
I just finished this on a 2000 Audi A4 (B5 Chassis). Worked great. The A4 has trim around the center console that has to come out, so the Radio, climate control, ash tray, and frame for all these has to come out first. Otherwise it is pretty much identical, and much faster than disassembling the entire dash. THANK YOU for sharing this method!! I also removed the drivers seat--it makes it easier to get under the dash for all those wires, and is easier to move the dash around when it slides out.
+Jennae Cosio
There is some center console frame that is easy to remove, and there is a big part that is not easy to remove. Only the easily removed portion needs to come out. There are heater ducts to the rear sears that need to be disconnected(they just slide apart. There is one heater duct and wire harness under the carpet by the drivers right knee that needs to be pried off of a mounting stud (I used a crow bar to pop it off). It will make sense when you look at it. This is necessary to get a wire bundle out of harms way when sliding the dash backwards. The biggest challenge I had was removing the climate control. Had to pull really hard to get it free. Buy a set of four radio keys off Amazon if don't have them already. I took a bunch of pictures--I can send them if you like.
Tachi
+Tachi Callas Thanks for your insight- I'm glad you had success with an A4!
Tachi Callas can’t the hvac control just stay in there, like in the video on the b5?
going to do that on my s4 b5 . after seeing your video i think i can do it by myself. thanks for sharing this HUGE life saver!!
How did it go?
@@AutoTechMadsen i did it today. pretty straight forward with your video. the hardest part for me was to put everything together after it was done. i was alone. definitely this is a 2 men job.... HUGE thanks for your video.
Fast and easy you take the whole car apart and fast and easy you replace the heater core.
😂😂😂
It’s not that many things taken out. Yes
Yeah man. Fast and super easy! Riiiiiightttt!
In other way mechanic take whole dashboard stripped...not even single button stays on their place
German engineering man... I love it until I have to replace a heater core.
Good job guys thank you for the informative video.
This is an excellent video and I cannot recommend it enough for someone needing to perform this repair. The only addition I'd make is actually a subtraction - no need to remove the bolts in the metal crossbar; only the nuts on the mounting studs, the small bolt near the wiper gear, the small center console bolts and the eccentric bolt connecting the steering column to the power steering shaft. Some of the harness plugs don't need to be pulled but they're so easy to replace it is of zero consequence if you pull a few extras just in case.
extraa, hvala mnogo, ubedljivo najbolji tutorijal za mali hladnjak!
Nice one. All works great. Only one extra step for me was a cable to a 60 A fuse in the ecu container. I used some steel wire to push the locking tangs in of one of the fuse blade holders and so unlocking the metal blade holder from the plastic fuse housing.
The trick with taking out and putting in the heater matrix from the plastic compartment is to curve it out so it misses the underside of the top of the dash.
I had this work completed in 5 hours including tools out, tea, lunch and tools away.
Congratulations, I watched others in which unraveled piece by piece. I'm from Brazil, and I am trying to create the courage to make the switch. I'm afraid to connect something wrong. But congratulations on video.
Leonardo. J. You can do it!
Wow, pretty slick. Done tons of em' the other way; but that's pretty ingenius. I'm gonna try that next time.
Well here I go tomorrow my first one I have a 03 audi A4 heater core out and just bought a 03 passat wagon and Guess what heater core out, so it begins great video
I'm pretty sure this guy said very little, if anything, and I understood this more than any other video I've watched
Thanks for the info, doing one of these today and tomarrow. Got it out in like 4.5 hours! Ive found these things are actually pretty easy to work on despite the VW reputation. Good video.
you make it look so easy , I'm about to do one in my 01' Passat , I've done a all the work myself on my Audi's and VW's and found that I can get parts fairly inexpensively and to work on them is not that bad compared to other cars I've fixed in the past. My first Audi A4 saved my life when I was in a accident, they are tanks, since then I was sold on them. So don't let the fear of costly difficult repairs detour you from owning a Vw or Audi ,its not true.
Amen!
You definitely made it look easy & less painful, thank you for the pics & vids.
+Timo 1111 I like your car, I put a 5mge in my pickup :)
+AutoTech Nice, Supras have been a hobby since '81
Man! Thank you for this tutorial, you saved my life! :D It was pretty good idea for no disassemly the full front of car-interior. I had a leaked heater core radiator. But i think, it's not a good work for one ppl. I did with my dad, and one of my friend. (3x) And it was 4,5-5 hour while we disassemle and reassemble the full interrior.
BTW again, thank you for this video. ! HONOR YOU!
Awesome!
perfect instructions guys, definitely not something to attempt on your own if you don't do this kind of work frequently. thumbs up.
+Alex R thanks so much!
Just did this yesterday. Thanks a bunch. Took me 6 hours. Still lots of work but thanks for the cheat
I might be picking up a 2001 Passat 2.8, 5 speed wagon tonight! flex pipe is bad and needs a new heater core...hoping to get it for a pretty low price, and this video will help a ton. thank you!
Good luck! Replacing a heater core in shop usually cost around $1,000. Maybe that will help with your negotiating :-)
+AutoTech what do you know about replacing the flex pipe? I know it's before the catalytic converter but that's about it.
if it was me I would just take it to an exhaust shop.
Great video, I'll be doing a heater core in about a week and trying to figure out the best way to do it. I'll be following your direction on this one.
thanks for the vid guys- im an auto body tech and always looking for as easier way to take things apart and i knew the heater core was gonna be an ordeal esp when i saw a diff one and they took every single part off the dash. ive got an 02 v6 4motion 2.8l wagon and hope theres nothing too different with this model. also have a 68 squareback lowrider- funny how both my vw wagons have no heat right now. thanks again for the info and excellent replies to others i saw with similar questions i had right off the bat. Cheers- mike.
Should be all the same- Good luck!
to me it was absolutely obvious the factory does assemble the dash inside the car, knew it was a better way.. now this should also work on a 2.8 b5 so this is the way i'm doing it tomorrow
+Markitos203 Let me know how it goes!
+AutoTech Forgot to thank you for the video brother!!.. works exactly the same way on B5 audi. took me 10 hours total and literary 2 hours taking the damn climate control, felt stupid when i got it. i got the core from ecs tuning for $26 with shipping. This is the way to go!! I can't believe people are dismantling dashes to the bone.
REMEMBER TO AIR OUT YOUR COOLING SYSTEM PEOPLE!!
The left heater core hose has a small hole right on top designed to release pressure when the hose clamp is pinched. warm up the car and simple pinch the hose clamp to release the air, when the bubbling stops and you got a constant flow of coolant coming out you should be all set. back to being toasty on the winter
so this is a fantastic idea! tomorrow I will have one B5, and i will try it. a lot of tanks for helpful video!
Well, I can only say ,Thank you for this video, I done it hard way, damn I disassemble everything today, what a shame because didn't watch this video on the first place. My bad, tomorrow is assembly day. :"( A long day.....
I’m sure you see another one soon- VW problems come in pairs.
Thank you very much, you saved me a ton of time and money. My 2002 Passat varied a little from the video but it was close enough that it got me through. I did not have the up facing bolt above the wiper motor under the cowl, there was just a rubber plug. In your video the trim under the wiper arms is on, I had to pull the wiper arms and plastic trim to get to a bolt in the waterproof electrical box under the hood on the drivers side.
Awesome vid! I'm going to tackle this project this weekend and you simplified the process! THANKS SO MUCH!
+Naomi Hopkins Good luck!
Great video. Just did mine looking at this tutorial.. everything went just perfectly.. the only difference was that mine was Irish car.. so steering wheel on the other side but video shows that it is literally mirror reflection of mine. Thanks again for helpful guide !
Thats Awesome!
I was nervous about doing this my self due to lack of time but it was pretty easy once I got into it. The hardest part was steering wheel shaft it took a T47 to remove it but what was quoted as a 7 hr $1300 job took me 3 hrs plus $100 to get a/c recharged. bonus tip buy a all metal heater core with top plastic mount to avoid doing this again the factory style units have plastic firtings and fail at the seals
What is the make model of the all metal core?
I'm curious too. Where do you find the all metal core?
Good and Quick method.
Thanks.
Jeroen from the netherlands
Y’all are definitely experts, because that looks like hell lol
It’s not so bad compared to the pulling the dash piece by piece!
Audi a4 guys. OK. Awesome video. Very good overview for the semi experience. As for my 98 audi a4, here's a few tips for you guys. There is no bolt by the wiper motor just under the wind shield. (so I took all my wiper arms and plastic off for nothing, my 98 model) I took almost all the wiring plugs off at the passenger footwell, except for the 5 that go to the door. I didn't take any plugs off at the drivers footwell. The note about the 30 amp works is right and there is 1 (the thickest) brown ground by the hood release. Before I watched the video, I took apart the center console including the black Frame that holds the climate control and radio. I may not have needed to do that because they didn't in the video BUT... I may have damaged some of it with the shifter if I had left it there. I had a hard time rotating the dash back with the steering wheel attached. It hung up on the seat. Even with the steering wheel off, the heater core was tight up against the windshield coming out. Over all great video. And doesn't separate the dash from the heater box which is another pain in the ass I didn't want to deal with. Any questions, ask. Thanks
+russellp73 thanks for all your insight and helping others
+russellp73 Did you do this by yourself, or did you have a helper? Any estimate on the weight of the dash/steering wheel? Thanks.
+Gary Allman absolutely get a helper its not super heavy but it is awkward - need to be careful not to break anything. Thanks for watching!
+Gary Allman get a helper. 30# per side ish. But it needs to go in straight so you don't damage the new heater core pipes. My wife helped me do it and it wasn't too heavy for her.
+Gary Allman Good job getting the wife in evolved- you two saved your family a $1000!
haven't tried this yet but this sounds like good advice. thanks for the heads up!
Good luck :-)
Going to give this a try tomorrow. Wish me luck! Getting cold here in Wisconsin!!
Very easy! The only thing I would add is there is no need to disconnect any of the red wires on the relay block, just detach the whole relay block and let it hang. No need to disconnect the drivers side quick connectors, just cut the zip ties that hold the big wire bundle to the metal dash support. This allows enough slack to swing the dashboard out. No need to use torx bit on steering rod u-joint, just use a 16mm wrench and tap it out.
Best video ever
Thanks guys
Thank you. This video was very helpful
looks like the real deal. Many thanks.
my god you saved me a ton of work thanks so much from Baltimore ,Md.One note keep your key out the ignition or you will need a vag.Come on winter I'm 4 motion with great heat ready for you.....
Happy to help!
you, my friend, are amazing. thanks for the great detail in this. helped me out a ton today
Awesome happy to help!
This is obviously neither fast nor easy, but thanks for sharing this video.
Thanks for your video man!
I did a perfect job.
Picked up an 03 Passat GLS tonight, owner tried to hide the bypassed heater core and I was able to pick it up for $500! (Amazing what you can do what you catch someone in a lie..) anyways, I really appreciate the video! I plan on using it as a guide here in a week or so.
I meant to post back, thanms for reminding me! Alrighty so I did mine Saturday night..
These guys are pretty spot on with what all needs to be done, but In my experience the drivers side harness at the kick panel didn't have to disconnected, as with that on my 03 the steering shaft was a t50 torx bit ( not a 6mm Allen like most have).
Lastly be gentle with the plastic, I noticed that mine were pretty brittle due to the age, luckily I got away without breaking anything.. but it's something to note.
+Jeffrey Collins
It sounds like a success!
AutoTech Absolutely! Although I have a mystery coolant link (unrelated to the heater core) that I have to hunt down now. Oh well, part of owning a peoples car!
+Jeffrey Collins
If you have a 1.8t- they like to leak from the coolant temperature sensor housing on the back of the cylinder head- just an Idea : )
Thomas EXOVCDS has all kinds of excellent videos on doing Volkswagen repairs
ua-cam.com/channels/m3WosFt2A-Z1P436Fkjfxw.html
That's exactly where it seems like it's coming from! I can see the steam and smell the coolant but I can't see the actual leak.. but it's definitely from that area. Thanks!
worked great thanks for the video it saved my hours
+HARELD SCHMIDT Happy to Help!
Any trick to getting the bolt out of end of steering shaft? I took off the 16mm nut and using a T-50 star bit on bolt head; won’t budge. I assume it rusted, currently putting penetrating oil on it. It’s the last thing to disconnect after spending all day tinkering. Thanks for the video!
Nice video looks like I will be doing this to my mother’s car . The video help a lot very nice job . 💪
This is genius! I am going to do it this Saturday. I would definitively buy you a beer/coffee/donuts no joke! if you send me your paypal
Nice! Will do it this way the next time!
SUPER THANKS!
It made job alot easier!!!
Good job!
Where is your shop, I need to change my heater core on my 2005 VW Passat 2.0 TDI
My grandfather's friend and I replaced a heater core in my truck it was a huge pain in the ass
After watching that it gave me a nightmare I had to go and pop a few Xanax to calm me down I did not look easy there’s more wires on there than a 747 jet
Abe, me too, his draw ad is deceitful. It's just a big ass job.
@@rufusrunsgsp4610 not as bad as it looks... no its not a honda, but this is kinda simple. all wires are color coded.
I swapped my entire interior from cloth to leather without a manual, 3 hours all seats power and heated and the door cards
I did my own radiator (service position and all) took 4 hours. no manual
I changed my whole front suspension, all 8 control arms, tie rods, sway bark links, every bushing under there, 4 hours. no manual.
Just watched this like well sh!t I done did all this other stuff this is going to be a 4-5 hour job with couple doobies and a 6 pack!
once I do it, I will post how long it took.. I will try do record it if I get a few extra hands on deck!!
@@joeyglasses4050 Did you do it?
Although the title is click baitey, this method is a 4 hour job instead of the ‘approved’ method that the flat rate book method lists at 10 hours. It’s still a crazy hard job.
Perfect video for us experienced mechanics that just don't know VW. Thanks
Great video helped me greatly although mine was right hand drive 👍👍
What country are in? 😀
AutoTech united Kingdom, Scotland
Awesome! Your a long ways away from me in the USA, Oregon : )
GREAT VIDEO!!!!! Thank you Sir:)
Great video although di you have to remove all the red wires? aren't some just to the dash itself?
I did this once a few years back after not having heat for 3 years or so. My mistake was using a plastic replacement. Now i have to go in again but this time it will be all metal OE VAG. Hoping not to do it again on this car.
I do look for passats for sale with no heat hoping for deal knowing this method.
Oh, it took me about 3hrs by myself the first time. I think i can get that down to 2hrs, not including having the freon evacuated and replaced.
Did another one today. It didn't go as smooth as last time. This was a 98passat wagon not sure if it changes things but the bolt under the cowell
Wasn't there also there was a 20 gauge wire next to the series of red wires I didn't disconnect when I removed the dash I broke it. It was an easy fix.
Also the connector the wires under the Ecm connect into I broke that when I rested it against the door. You removed the blower motor connector and 2 10 mm bolts above. I'm not sure why there is no need. On this car the heater core was very hard to r and r. The dash was in the way of lifting it straight out. I believe I folded the plates over. It works good in 70 degree weather but soon it'll be 14 degrees hope it don't come back.
+Paul M You Caught me!.. Haha, You're right- you don't have to un-plug the blower or un-bolt the Air Bag : )
+Paul M What year/model was the other one you did? B5 or B5.5?
+Gary Allman I believe it was a 2000 B5
Sorry took so long to replay
I'm not sure What it was I've worked in 100 cars sense then and they all fade together after a few days.
I think it's a little bit complicated will see if I can do it thanks for showing us the best way to do this
Greetings! Just got a 2003 Passat that needs heater core replaced. Do you have a step by step guide that goes along with this video?
Wow. Thanks for the knowledge.
This weekend I plan to do this myself. I just need to ask, what tools I need? Something special? Some unusual torx/wrench size or type? Something I need to prepare before I start beside of draining A/C? And main question, am I able to do this SOLO? Pulling out the dash a putting it back. Anyway, THNAKS A LOT for video like this, very good!! Best regards from Czech republic, Passat Varianr ´03 1.9TDI owner.
Can you tell me what make the new heater core was? if i'm going to the effort of replacing mine i would prefer an all metal one like the one you fitted. Thanks.
I got it from the dealer
What a great alternative to the other method of complete disassembly. What is the make and part info for the core you used with metal tubes? Thanks
Don't know but it came from VW
Is the removal of the glove box absolutely necessary?
I've actually found a few on ebay: www.ebay.com/itm/Audi-VW-Volkswagen-Heater-Core-Premium-8D1030B-/141543764160?hash=item20f4aa70c0:g:FvUAAOSw9N1VnFo9&vxp=mtr
you night have to in order to get at the center console bolts
Can you change the evaporator coil the same way? Where are you located
Donald Shapiro Yes you can, but I think you will have to separate the HVAC from the Dash. Also you may have to disassemble the HVAC box.
I cant find the 10 mm bolt under the wiper cowling only something that resembles internal hex bolt on 2000 b5, is that it?
Why do you have to unplug the wires by the ECU, are those sockets attached to the dashboard?
Is replacing evaporator doable the same way or you have to detach and take apart the HVAC box?
That is awesome ... Fantastic! 👍🏼
Can this also be used for an audi a4 b5 ?
athor11100 yes you can!
thank christ, I've been driving in Jersey / Boston winters for 6 years with my '98 2.8L a4. Heated leather seats made it bearable for just me but horrible for passengers. Literally all I need it to do it blow max temp air in the dead of winter for defrost. Every other day of the year IDGAF, I never even use the AC (which also doesn't work LOL)
Need to replace servo motors also. Will I have access to them doing it this way?
Can't get the center console/ cup holder area out for the screws at point after the steering wheel and wires part, any helping advice?
I followed the instruction of this video I used my phone to keep the video on pause and as I worked mine was an automatic that had a shifter cable I had to deal with also there was no instructions about the order of red wires on the drivers Side. They all separate when the dash is removed. It doesn't matter one post is different size the rest just need to go on the red post.
It went very fast was done in about 10 hours include valve cover gaskets and tune up.
The heater core doesn't quite clear the dash. This car was an old beater so I trimmed the dash back an eight of an inch the windshield trim covers it up.
Great video. Need a how to on tundra front wheel bearing 2wd.
Paul M The red wires (30 power or Terminal 30) are all the same other than the size of fuses- they are connected to straight to Battery power. Unlike Terminal 15 which is Ignition switched power.
Thanks for watching!
Is there an easy way to remove the electrical plugs with the two snaps on the sides like in the ECU box and under the side kick panels? I have been using two small screwdrivers on each side of the plug, but this become tedious with so many of them.
I'm curious if there is some kind of hand tool that would assist
Yea did y’all ever get an answer for this??
At the very beginning you show all the Engine Control Module wires unplugged under the hood. There's a bolt on the backside of the ECM box I cannot for the life of me reach with any of my tools. Can you advise? And why does the ECM need to be unplugged for this anyway?
The ECM needs to be unplugged because it comes out with the dash pad.
I think used 10mm socket on a small 1/4 drive ratchet.
Good luck!
@@AutoTechMadsen Thanks!
AutoTech thanks again. I had to remove the windshield wipers and plastic under them to get to it, but I got it.
One more quick thing. In that first image, am I correct that I see the heat hose disconnected, but the A/C line can stay plugged in?
Yes the AC must be disconnected.
Feel free to ignore me if I’m asking too many questions. I reassembled the dash. Car started fine but with airbag fault. Left it a couple days and now it won’t start at all, even with a jump start. I’m at a loss. Any thoughts?
Good point Autotech. Thanks. Let me get your thoughts on another thing. When flushing the HC is there a possibility of damage w any chemicals used or the air pushed in to clean it.
+Xavier Gunz In my experience I have not had good luck with the use of chemicals. My version of a flush would be, use pressurized water and or Air alternating from both the inlet and outlet of the heater core, repeat as many times as it takes. Keep in mind there is always a risk of causing damage to the heater core.
Hope that helps!
Many thanks for this video. This help me a lot.
But there are some difference with the european model. The main one is with the outside fuse box.
There are 2 fuses 50A & 80A with their support to unplug (ref:8a0937530) but for now i dont find the way to unplug the pin.
Did you managed to remove it on european model with this method ? :D
Thanks
Hey guys, so far so good, thank you for the great video. I just need to remove the steering column bolt and then slide the dash out. Just wondering, what star socket size did you use to remove that bolt on the steering column. Mine has a star on one side and nut on the other. I can probably get it off without it, but just wanted to see if you remembered what you used? Thanks again!
Hi there, this method can only be done in this model?, what about the other ones, more specifically, what about jetta mk4 which is the one I have?, thanks a lot.
It won’t work on the Jettas - I tried it once and failed
@@AutoTechMadsen Thanks man 👍
I didn't notice any air conditioning connections in the video - unless that was them at 0:27 beside the battery?
yep you found them : )!
Thank you for this video. I am going to attempt this soon on my 2002 Passat. While I have the dash removed to change the heater core, I'm thinking about replacing the various Climatronic servo motor parts that control the flaps and temperature blend in the HVAC box assembly. Does your technique provide access to those parts or not?
I did try to to remove a dash in a Jetta - Unsuccessful becuase of one bolt that holds the dash support to the top of the firewall. On the Passat the bolt points up and is easy to remove from under the cowl. With Jetta the same bolt points down and the windshield is in the way preventing it from being removed.
that's wrong the way they VW manufacture put that heater core in these Volkswagen's and the are known to go out quickly
So it will or will not work for a Jetta?
My question is, can the AC evaporator be accessed in this manner too? It looks from the video that the air box will have to come out to get to it..
It doesn't appear to help with that, what did you find?
Good video.
S D Thanks!
How long did it take total? Roughly?
Will this work for a 1999 Audi A4 2.8 as well?
Yes it did great the middle console is a bit different , but it is awsome
did the job , Bill here from werks .. car runs , but no windows,locks , tail lights ,rear turn signals, codes 1330, 1335, 1336, checked all wires , plugs and pins etc , do the control ecu and ccm need to be program again ? any help please , thank you !!!
No programing should be necessary- how ever sometimes programing can get messed up when battery is disconnected but this very very rare.
I would double check wiring to the studs and don't forget about the ground connections on both sides of the dash. What about fuses?
Do you know what your 3 codes are referring too?
I have a friend with a 2003 Passat with a leaky heater core - and no money. I was looking for a replacement core on line and came across this video - it's given me the courage to give it a go!
I've watched the video several times and read through the comments, which were also helpful (have a Torx50 socket on hand). I have a question on the air conditioning. In the video, the first frames show hoses hooked up - is that to drain the A/C? If so, do you then disconnect any hoses going through the firewall? On the heater side I can see where the hoses were disconnected - but don't have a clear understanding of what happens on the a/c side. Any help there is appreciated!
That's awesome!
@@AutoTechMadsen I have the same question as Bert but, i didnt see your answer.
You have to drain the AC, then in bolt the joiner for the AC lines. This joiner is next to the battery on the firewall from the engine side. There is also the heater pipes, a 10mm bolt and the cables from the ecu tray that all have to be undone from the engine bay side of the firewall
The 10mm bolt is a bugger to get to but it is there. Look in the video to see it’s sneaky location.
good video jobs done thank you
+Cj Fuller thanks for watching!
