Audi B5 S4 Heater Core Replacement 

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.

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.

As a b5 owner I love your videos there are barely any good videos of the car keep up the good work

Hey man It's hard to find vids with people working focused on both things, doing the mechanics as well the filming, you also make sure that we know exactly how things happened. It's amazing how helpfull is your work, simplifys lots of head breakers. THANK YOU 1000's times!!

Who else broke there glass?

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.

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

So basically if you have a POS A4 when the heater core fails sell it and get another POS A4 lol ;)

Or you could always, as I have seen in another video, just buy a small heater core about the size of the cabin air filter. And plumbing in there! Wow that was a whole boatload easier!!

No need to unscrew passenger airbag bolts, in addition I removed front driver ABS sensor connector.

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.

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!!!

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.

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

Bro....that is ALOT of work, Great job man!

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.

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.

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).
