Super video! Thanks Thomas. Saved me a ton doing this myself last night. I replaced mine with the upgraded cast aluminum version. No more leaks!!
Thank you for sharing your DIY success! Those cast flanges are great!
Thanks for watching!
I have tried to watch your videos many times in the past,but just couldn't... It wasn't so much for the constant movement,but the lack of sound and not hearing any explanation. This is MUCH BETTER! Thumbs up and subscribed,especially since I sometimes work on European cars too!
Keep up the good work! 👍
I've changed / adapted for my viewers... you can't expect someone to make "Top Notch Videos" while they are "at work". I don't always talk... but I think I provide enough info (be it text or verbal info) to help the viewer. I have several subscribers who are deaf... they haven't had any issues since my channel started. I'm a visual learner myself... that's why I record in First Person View format, which in my mind makes learning how to do a job a lot easier. I reply to any and all questions / posts... not too many channels do that these days and I've been doing that since day one. Nice to see you onboard .
Thomas EXOVCDS I certainly wouldn't be entitled to expect anything since I know how hard it is working on these cars as it is,let alone filming it while working in a shop environment. So please don't take my comment the wrong way,I just think your videos are much better now,that's all...
Glad to be on board! 👍
Sorry... I have a constant need to explain the reason behind my recording style (for the benefit of potential new subscribers who are reading comments). No offence taken (sorry if that's what it came across as)... just felt that things need to be explained since my average view duration is under 3 minutes (because people don't give me a chance or they don't bother asking me questions)... but people like to read comments (weird). =)
Thanks, probably the best video I see, just did my ,02 Passat, thanks for listing the tool socket & Allen wrench sizes, took me 4 hrs start to finish including set up n clean up, Tom
Thank you and thank you for watching!
Great Video. Car was loosing coolant for about 3 months and couldn’t pin point the location. Was finally able to hear the leak. Searched and found you video. Only extra I used was a flexible long funnel by the oil filter to catch the coolant from major spill. Secondary Air Pipe Elbow by Turbo was brittle and cracked after movement. Took about an hour (help from vid) to remove. Waiting on mailman for replacement part. 👍🏼
Thank you for your DIY input / feedback... thank you for watching!

Just looking at your hand later in the video. It perfectly explains why we charge what we do to get a job done.......Its rough on ya!
Nick It's funny because most of the time I don't even notice it while working.... unless it's a gusher! LOL
Always fun working blind to get bolts out or sutff unhooked. As always you make it look easy.
The bloody hand might disagree a little! LOL
@@EXOVCDS I have to do it my self tomorrow and I swear I'm shieting in my pants. DO NOT LOOKS EASY at all!!
Take your time... as long as the engine is cold, you'll do fine.
Can't believe I missed this one last week. Great video Thomas, that one looked painful to take out!
I had another one a couple of day later. Sigh!
wow what a pain in the hoop. Good job
My wife's '04 Passat 1.8T is leaking back there and I can't see exactly what. Your video is awesome! Here I go. Wish me luck. I've got this video bookmarked for frequent referral. :)
It took a little longer than you, but I got it all disassembled. Thanks!!! Now to get parts and reassemble...
Thank you for the update! I'm still at work... was going to reply later tonight once I'm at home.
REAR coolant flange! WTF. You did a nice job on that one Thomas. Never got too frustrated. Well done!
When I get frustrated... I turn the camera off. LOL.. easy out for me!
I work at Pepboys and I just got this same one problem on a Passat. After watching this I’m like “yeah… not happening”😂
It only took me 15hrs to do this. No mechanical experience what so ever other than changing my oil. LMAO but I finally got it done and fixed thanks bro you saved me 280 freaking dollars
Vince Abarca Nice to hear that you were able to do it yourself and that my video was of help. The next time, you'll be able to do it much faster! 5 to 8 years is the average lifespan of those flanges. =)
My 2004 A4 obvoiusly need one now as it leaks 'somewhere back there', I didn't even know it was there.. :p This is probably a $700 job here in Norway..
Had the PLEASURE of doing one today. Goodtimes.
LOL.. nice!
Getting ready to do this for the 3rd time. Replaced the first one, had to re-do it because the O-ring was deformed on installation, and then it blew apart last summer. I'm installing an aluminum one this time.
Aluminum one will definitely hold up longer! Thank you for watching!
good thing I deleted the whole SAI on my b5 with the combi valve and everything :D way more motivation to do this job now
Just installing the aluminum replacement coolant flange (available at ecs tuning).
Good alternative!
@@EXOVCDS Another point of failure eliminated
The words coming out the mouth cracked me up. Good idea. Let me guess, this is one of those jobs you hate seeing come in. That was challenging.
The "Mech a nic" & I are having fun placing each other's logos in videos! =)
Thanks for the video. Have to replace mine on my B5. Going to upgrade to the aluminum piece, so only have to replace o-rings in the future.
Thanks for watching!
what a fecking nightmare of a job, but you stayed so col throughout. Well done and I am watching this because my Audi has a water leak at the back of the block and I suspect that I will be nowhere near as cool as you with lots of swearing and cussing from me...thank you for showing us how it should be done.
This video is very helpful. 02 passat is losing coolant not sure where. Filling coolant about every 2 weeks. At least I now have an idea of what it could be and the repair to fix it
Coolant can leak from many places... this is just one of them. Follow the leak to its source. Thank you for watching!
Yes, I know that question. What will it be today... hm....I always wonder how you manage to be so accurate, AND your filming, ... AND your explaining... :-))
You'd be surprised how many people expect "more"! Someday I will work out of my own warehouse, spend more time on video production and have more in-depth content... until then (as long as I'm working for someone else) those people will have to wait. Have you heard of "Die Autodoktoren"? ruclips.net/channel/UCcnmNzv0yEEYPM6Oa86unhQ I just subscribed to them... also fun guys! =)
Understatement of the entire video = "Good luck getting those bolts back in !" Can I do it without dropping 'em less than 10 times = NOT ! Good video, thanks.
Thank you for watching!
VW and Audi seems to have plastic clips and metal brackets that are designed to cut you up. I've done most jobs on Vw Passat and Audi A4. When I replaced the head gasket on A4 the coolant flange was removed and checked while the head was off, much easier. I had to change the Passat one though :( Good work Thomas.
They can definitely put up a fight! =)
thankyou soooo much for this video, life saver!!!
Thank you for watching!
One time what I did is unbolt the front portion of the subframe so that the hole engine sits lower and farther from the fire wall especially if you have to replace all the pcv system and other cooling system parts like coolant temp sensor is a good idea. Unrelated to this video the other day I did a timing adjuster gasket set without removing the exhaust cam from the head I just realease all the cam bearing and the timing belt was still on the pulley I think I was the first time I did it like that it worked well I know in one video U mentioned that you never tried it that way but maybe you did after all.
I've seen images of someone having done that... very clever and gutsy at the same time. I'll be trying that the next time a chain needs to be replaced... removing just the intake cam works well for just the gasket & tensioner.
I’m changing mine right now and I’m all these videos no one mentions the gasket inside the heater core hose. Oh yeah. A total of 4 gaskets not 2 or 3
This is why I don't go into specifics with my videos. People need to be responsible for their own parts sourcing... it's never a good idea to just rely on generic videos.
Service manual & parts catalog information will provide required information.
Heater core hose o-ring can be reused 95% of the time.
Alot of trouble getting all of those hoses off. Mine Fell off when I touched them..... into little pieces.... ECS loved me when I had to replace EVERYTHING in the PCV system.....
If you get 8 years out of those components... it's not that bad, and it's always good to replace most of / all of the components, so that you don't have to go back in again later. AND, the next time you go back in there, things will be easier... right? LOL
in the same boat atm waiting on a nice package from ECS also with a new breather hose kit, coolant flange, etc....
Great video
I’m working on this now
Thank you for watching!
I’m doing this tomorrow. Sad day. But this video has helped
Let me know how it went for you. If you get 5 to 8 years out of the new flange... that's not bad.
I just want the coolant leak to be done with. I seen a video on an aluminum upgrade flange I may do down the road.
I'm not sure if aluminum flanges are available for the Passat style of flange... I know they are for Golf & Jetta.
Is it an engine code spec maybe? I seen them on a 1.8t. But I have an awm. So you are probably right
@@nolanmoore7682 Design / layout of engine. Your engine is Longitudinal (front to back) whereas Golf & Jetta are transverse (side to side)... the flanges are shaped different and there are 2 different designs for the Passat. I'm sure that eventually, metal flanges will also be available for the Passat.
Holy crap Thomas! First, you mentioned that the secondary air injection air-feed hose was glued on and it had a clamp on it. I don't get it why the hose had to be glued on. Even after you removed everything to get to that flange, it was still damn tight in there. And then when I saw that bloody mangled left hand, nope, I don't want to do that job :) Nice work Thomas!
Leaving my mark on the engine! =)
I love and hate this job. I like it cause it's complicated and takes time so more time for me to keep my head under the car and not talking to service writers, but damn it's a hard one too.
Coming from a guy who replaced a timing chain etc on a 2.0T... I have yet to do one of those! =)
I've done one of those... sorry, I should have said 2.0T FSI / TFSI
Great video Thomas!
+Nick Thank you.
all that and not one F bomb. Props.
Have to keep it clean for the younger youtube audience! =)
My drive home was full of expletives that day! LOL
Nice video. I had a shop change the coolant flange. Notice a slight oil smell from the heater vents when driving since the flange was replaced. When I open the hood, there is no odd smell noticeable there and everything looks fine under the hood. Just wondering what could be causing this?
Watch this video and then check your engine for similar issue.
ruclips.net/video/eBbN3ba4IAQ/видео.html
@@EXOVCDS There is a pressure control valve which needs to be disconnected to get to the flange. Would the smell come if that valve is not reconnected correctly?
@@alabbas4930 2:09 The pcv breather? As with any fluid leak or smell... follow the leak or smell to its source. In some cases, you can see the pcv smoke. If you don't see anything in the daytime, wait until it is dark, start the engine, open the hood and look around the engine bay with a flashlight.
@@EXOVCDS took it back to the shop and they said it’s fuel injector seal leaking, causing fuel smell in the car. $180 (in Canada) to fix it and they said they would put charcoal cabin filter ($40 cost) and wash/clean the engine($60 cost) to clean residue. Strange why I noticed the smell right after coolant flange replacement. They said this issue has no connection with coolant flange replacement work.
I just finished this repair today and my left hand is completely bruised and scraped up. Also should have watched this video before doing the job and after. Lol
Lots of fun these coolant flanges! LOL
Thank you for watching!
aeb is so simple
@@MrSambam313 yes, more room / less stuff.
about to do this job soon as i found my coolant leak finally after a year of searching and replacing other suspect bad hoses and o-rings. do i have to remove the combi valve? i have my converter and air box out right now for other reasons and it seems like i have enough space, unless the combi valve actually covers the coolant flange which is hard to tell when you cant see. thanks for any insight on this you can give!!
Removing the combi valve makes things / access easier. Try with the combi valve in place... you can always remove it if you have to.
I have one of these cars, thats the trouble for most jobs you have to dismantle half the car!
Luckily, it gets easier / goes faster the 2nd, 3rd, 4th... time! =)
@@EXOVCDS I take my hat off to you, I wouldn't like to attempt that job!
I did this job this weekend. One word of advice is to replace the o - ring that is between the metal coolant pipe and the flange. It leaked until I put a new 0 - ring. This job is difficult. If you don't tighten the two bolts that hold the flange to the cylinder head enough it will leak, fit you tighten too much you run the risk of striping the threads. Is there a torque wench small enough to be used in such a tight space?
Thanks for the DIY feedback!
Yes, always replace o-rings, seals, gaskets etc. Those who "turn wrenches for a living" develop a feel for how tight something is, no matter using a wrench, 1/4, 3/8, 1/2" ratchets etc. Taking into account the size / thickness of a fastener one can usually gauge the amount of torque that is required / should be applied. 6mm studs are usually 10nm... a service manual should list actual specs.
I've done CTS and Kombi valve myself, no biggie but I got my mechanic to to the coolant flange! too tight for my hands!
My hands would agree... the bloody one at least! LOL
HOW DO YOU STOP THIS THING FROM LEAKING!!??? Omg!!!! I have had 2 new and both just leak regardless!!!
Leaking where... there are 4 places on the flange where coolant could leak.
- where the flange meets the head
- where the temperature sensor sits
- where the heater core hose attaches
- where the bypass pipe attaches.
Over tightening, under tightening, misalignment, worn heater hose flange... etc etc. Replacing a part is one thing... you need to make sure that everything else (along with the new flange) are mounted / fit correctly.
@@EXOVCDS thank you!!! It was leaking from the pipe entrance into the flange… had to get another rubber ring to fit correct before tightening the 2 bolts on the flange…
perfect timing, I ordered the flange 2 weeks ago and haven't got around to it yet. I will go for 1hr removal and 2 hr install
Have fun! Let me know if your time estimates worked out (should be fine).
I want to personally thank you for your videos. I just finished a timing belt, water pump, coolant flange, cam chain tensioner (dropped and broke the old one, oops) pcv system and cam seals.....thanks for helping me out!
Haha this has been an experience so far.
It's a tight space... that's what she said!
I broke the plastic elbow for the air pump line. Got it cheaper than dealer though. I like vw if I’m just driving. This is my third vw. Everyone swears I’ma vw tech lol
you don't know how much I was laughing 😂😂😅💀
You mean you spotted it? LOL
Thomas EXOVCDS how could I miss it lol. as the video goes on your gloves just give up on life.😂
The mech a nic No time to change gloves or apply a band-aid... people are watching! =)
Thomas EXOVCDS screw that, I go through a box of gloves to change a fuse😂safety third. btw I shared your video on Facebook.
+The mech a nic Thanks! I'm not on the Facebook yet. Maybe next year. 😎
working on these cars is like performing surgery
Work by feel... that's what she said!
I think this is my problem but dam show the part, maybe this helps, but I don't know
The part can be seen at 22:06
I don't know if that's what your leak is... you have to go look.
thank you so much ;)
Thank you for watching!
The 1.8T requires a mandatory blood sacrifice... and it gets it one way or another.
Luckily, I don't see too many anymore... reducing my blood donations per year! =)
I have to do plumbing on three of them. One of them that lower coolant pipe that goes into the engine, has a rubber stopper mid pipe, with a mid screw locking it to the engine and then splits at the end to feed I think the heater box and go off somewhere up top. I managed everything except that plastic connector that has the grooved fitting and the pull up spring lock. I sprayed the spring lock and pulled it up, it came off, popped off. It seems like this end of the metal pipe is stuck in there. Any ideas? should I replace that hose and the metal pipe together? When I ran the engine on this one, I smelled a burning plastic smell. I was thinking it was this pipe because it looked like someone epoxied it with some grey gunk that might not be made for that kind of heat. The pipe is 17 bucks new, I'm not sure about the hose and connector that feeds out of it.
Can you send me pictures of what / where the part is? I only know of the rear coolant flange and how it attaches to the metal pipe that goes to the top radiator hose. send images to fkh161@fkh161.ca
I've order a new flange. I've got to remove my old one and replace it. should i be flushing coolant system and replacing after swapping the flange?
Before or after doesn't matter.
@@EXOVCDS I wish i could show you a video of how badly mine is leaking. I woke up to a pool the length of my passat wagon this morning. When i came home from a run to Napa (about 10km round trip) i could see it dripping from around the flange and onto the transmission housing.
@@gingefpv It seems that you have uploaded videos to your RUclips channel in the past... it's even easier these days with a smartphone & RUclips APP. Just post the link here once you have uploaded it. =)
I k ow I'm late to the party but I have a 98 a4 1.8t what site can I find the cast aluminum flange at
www.ecstuning.com/Search/SiteSearch/1.8t_aluminum_coolant_flange/
Google search "1.8t aluminum coolant flange" to find other sellers.
the 5mm hex bolts feel like they're always on the limit of stripping >.
Yeah, makes me wonder who tightened it the last time / why so tight.
That was a tuff one . Hose's didn't want to cooperate .
Real world video... not too many people sit through them, thank you!
I do not work on VW's but I learn from your vids !!
+N Smith If you say so. LOL

Great video. Do u have a link for the new part by any chance? I've looked online and local auto parts and it is different

@@EXOVCDS - thank you for fast reply. Ecs don't have it either. The one im looking for is just like the one on the video. Has to be bolted to the head and the other end bolted to a coolant pipe towards the driver's side.

Now is this for the ATW engine?
Will be similar if not the same.
Is it any good that HHS 2000?

Could you hold the camera steady?
No.
Sorry... I guess I should explain. The camera is mounted TO MY GLASSES. I"M RECORDING WHILE I AM WORKING. I'm not shouting, I'm stating the obvious.
I think passat is more hard to replace then audi A4 or A6
Possibly.
I'm pretty late on the comment but my God am I not looking forward to this.. looks like an absolute nightmare. AND I have to replace the oil pan because I've got a hole the size of a penny.
It's not too bad, even though I said pain in the... it's the editing that I didn't look forward to. The oil pan will be a tougher job... be sure to raise & support the vehicle correctly. I drop the subframe... some have success by raising the engine.
is it possible to remove flange without removing combi valve ?
The more room, the better.... so I would remove the combi valve. You can try to replace the flange with the valve in place, if you want to.
I tried, FAILED miserably, the Turbo Oil line was also on top of the screw that binds the Flange and Oil line to the Block, 2003 VW Passat 1.8T. just FYI for everybody, thanks for your videos on PAssats dude, you are the only one out there!!!
No, u will never line up the lower bolt for the flange, I tried it, once u remove the comi its a piece of cake from there
I like your make of video
Thank you!
That was mud, not coolant. Sorry for that Passat.
It was actually pretty clean... it only looked brown on the grey floor. =)
