Great video, no wonder I couldn't see it just looking into the engine bay! Great car but strange engineering. This will be a great help when I change mine

Thank you very much, very good video 👍

couldnt have done it without this video. thank you quick tip for everyone: (13:11) mention when removing the jubilee clip holding to the largest piping on the flange, I found it easiest to use some hose clamp pliers after twisting and bending the thick hose so that the assembly was above the engine so you have access to the clip. Other wise you are guessing where the spring elements are , as they are underneath the hose and not visible.

I have the same issue with my 2008 2.0 liter. I got an ECT code a couple years ago so I replaced the sensor in your video. Everything seemed to be good for a while but now the whole area is leaking. I might have botched the ECT job so I'm giving the coolant flange repair to the dealer this time. Thanks for the video! Figuring this one out was frustrating. No drips! The leaking coolant evaporates instantly due to all of the hot parts in the vicinity.

Absolutely brilliant video. Done everything step by step. Hats off to you. Thank you so much

I'm about to take this job on this weekend, great video - thank you! I also learned that you can bleed with engine idling. I've always bled with engine off and cold. And then I run it up to temp and bleed from the heater core hose while the engine is running.

Great video Mr Knight ! Thanks so much for all the tips 💪🏼

Thank you for your valuable video. It's very helpful for me.

9:14 recommend to replace the heater core hose with O-ring inside of it... and other O-rings all around. No RTV applied

Those electrical connectors are a right sod to unplug! How did you make it look so easy? 🙂 My wife's car has the same engine and when I replaced the sensor, the earth pin didn't make contact and gave all sorts of odd effects. When you reconnect it, make sure all four contacts are in place. Cheers!

I would go for aftermarket aluminium flange(Chinese) with OEM O-rings

Am going threw the same issue not looking forward to doing it looks like a nightmare 🙃. Thank you for the video

Allow plenty of time, make sure you have everything you need for the job and think about all the money you will save by not having to pay labour charges! It needn’t be a nightmare.

@@Savage_K if it’s the lower connection, removal of the metal clip will enable release of the hose. In terms of the side connection, sometimes it’s easier to disconnect the hose at the other, more accessible end and then remove the flange complete with hose still attached. Then swap it over to the new flange while off the car and easier to access. They are spring clips and made way easier by having the correct tool.

I've seen this in several cars and now my nextdoor neighbors 04. Most I've seen seem to be caused by the cam seals or other related seals like the valve cover gasket leaking. They leak oil on that plastic coolant manifold which cause the plastic and rubber to swell leading to coolant leaks. Basically a whole bunch of little things. Ugghh fml

accuatly this is Audi A4 B6 1.8T ,,anyway thanks for the video ,,good job .

Thank you. It is most definitely a B7 which was essentially a facelift of the B6. It is definitely not a B6!

I have a b7 a4 with the 1.8t but I do set angine parts shopping up for the b6 to get the engine option

Great vid 👍 I don’t think we got the 1.8t in the b7 in the US, you’re fortunate as the 2.0t seems problematic (maybe it’s just the early ones that had excessive oil consumption). Cheers 👍

Thank you! Yes the 2.0 was a problem for some. I’ve always been a fan of the 1.8T engine, especially in the smaller VW Golf and SEAT Leon.

What is the tightening torque for the screws?

Surprised you didn’t change the coolant temperature sensor while you had the opportunity, that seems to go quite often.

Was my friend’s car, so I just replaced what he asked!

I can't figure out why everyone goes at this from the passenger side? This took me 1.5 hours to do from the drivers side, only removing the coolant tank and part of the breather hose assembly with three hose clamps and nothing else. One of the easier jobs I've ever done on this engine lol.

do I need to drain all the coolant to perform this job?

@autoknight747

@@TwoCowzBrowze If I was performing a full coolant change I probably would but otherwise the removal of the hoses and flange will allow coolant to drain to that level on the engine, leaving the level below that intact.

Just a question, was it in the end the flange itself or the cooling Hose with the little metal spring in it? I heared it multiple times that not the flange failed but the Hose with the molded Plastic Part. Thx in advance

It was the flange in the end and the hose was fine. It didn’t lose a drop of coolant after the repair!

Guys they sale a permanent fix for this just buy the aluminum version takes like 30m to switch out and ur done .

Failure to reach normal operating temperature is often due to the thermostat. It may need replacing.
