VW B5: 1.8T Passat rear coolant flange removal

[@vinceabarca]

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

[@EXOVCDS]

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. =)

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! 👍

[@EXOVCDS]

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). =)

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. 👍🏼

[@EXOVCDS]

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

[@FZERO20]

I work at Pepboys and I just got this same one problem on a Passat. After watching this I’m like “yeah… not happening”😂

[@alabbas4930]

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?

[@EXOVCDS]

Watch this video and then check your engine for similar issue. kzbin.info/www/bejne/m3PFf2aYlpl8d7M

[@alabbas4930]

@@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?

[@EXOVCDS]

@@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.

[@alabbas4930]

@@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.

[@calm4477]

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.

[@EXOVCDS]

They can definitely put up a fight! =)

[@baxrok2.]

REAR coolant flange! WTF. You did a nice job on that one Thomas. Never got too frustrated. Well done!

[@EXOVCDS]

When I get frustrated... I turn the camera off. LOL.. easy out for me!

[@NDAGR-]

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

[@EXOVCDS]

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.

[@v0lts]

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

[@coache1nine]

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.

[@EXOVCDS]

Thanks for watching!

[@V10PDTDI]

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.

[@EXOVCDS]

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.

[@jeremyconger7367]

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!!

[@EXOVCDS]

Removing the combi valve makes things / access easier. Try with the combi valve in place... you can always remove it if you have to.

[@ericherrera5405]

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?

[@EXOVCDS]

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.

[@m2mark1]

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.

[@nolanmoore7682]

I’m doing this tomorrow. Sad day. But this video has helped

[@EXOVCDS]

Let me know how it went for you. If you get 5 to 8 years out of the new flange... that's not bad.

[@nolanmoore7682]

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.

[@EXOVCDS]

I'm not sure if aluminum flanges are available for the Passat style of flange... I know they are for Golf & Jetta.

[@nolanmoore7682]

Is it an engine code spec maybe? I seen them on a 1.8t. But I have an awm. So you are probably right

[@EXOVCDS]

@@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.

[@Noneoftheabuv]

HOW DO YOU STOP THIS THING FROM LEAKING!!??? Omg!!!! I have had 2 new and both just leak regardless!!!

[@EXOVCDS]

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.

[@Noneoftheabuv]

@@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…

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.

[@EXOVCDS]

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.
