I’m a Nissan tech but drive the good old Audi .. doing this job now .. not as bad as you would think but I’m also used to working blind and in tight spaces. Good tutorial 😀
This was a tough job-a lot of blind work in a tight space. Not to mention that my hoses were fused so hard to the pipes that even a pick wouldn’t free them. Took me about 5 hours and I couldn’t have done it without this video! I really appreciate the clear instructions.
Veteran mechanic but still enjoyed watching someone else do this, before I tried Trying to fix neighbor’s A4 Turbo Thanks for the part links Dealer wants an arm and a leg for these parts
This is a great video and exactly what I need to do to our car. The dealership quoted me a little over $1,200. Instead I spent about $170 on parts and planning to do this in the next few days. Thanks for sharing your knowledge.
They quoted $250 in labor, and the parts were double the ones you listed, plus I have Amazon prime, thanks for listing the parts. My hoses did have the part numbers so I used then also to assure myself...looking forward to doing this job, for some reason I get excited working on German cars...p.s I also bought a very expensive gasket kit(3 o rings for $35) for the vacuum pump, I noticed the port sweating oil...any advice on that, im hoping that cures the check engine large vacuum leak code if not go to the n80 valve.
Wow, just wow. This was an amazing video! I've done the timing cover gasket which is around the same area of this car and I can't imagine how difficult it was to get some of those camera shots you made. I learned a lot from watching this video even after working in the same area. Bravo brother! This was a lot of work to put together and your style of shooting and explaining is very easy to learn from. Fantastic job!!
Did mine today and this video is very helpful, also found that previous owner had someone worked on it and the grounding bracket was not put back to vaccum pump, had to make sure to get that back in place.
Thank you!!! The only thing I have ever done to a car is change the brake pads and spark plugs but never worked on anything else and this video helped me change the coolant flange and hoses on my audi with no problems.
Video was very helpful. A few months ago, I replace the vacuum pump...that was easy compared to replacing this coolant flange. Yes, I cut the hose, but that tiny razor blade was really inadequate and getting the hose remnant off the pipe was a real pain. I removed the pipe to get the pipe clean. This took too much time... I should have paid someone to do this, I kept dropping parts! Thanks again for the video, I'm up and running again, without issues.
Excellent demonstration. The small ratcheting drive is almost essential so buy one before you start. Note that the short hose between the flange and top rail has different sized ends so you can use a standard cooling system hose. Thanks for posting.
@@HowtoAutomotive this is nice video, about a short hose connect to coolant flange that you cut before remove the flange, is it easer to install this short hose to the flange before you install the flange to cylinder head? is it right? Thanks
when i heard "you don't have to have a tool like this" ...my brain automatically added "but it helps"...if you've seen the that guys vid, you know what I'm talking about lol
What is that part that you have your hand on at the 12:22 mark. The black things in the white packaging to the left of the houses. I don't see this listed in the list of parts and I didn't hear the name in the video.
A good tip is to buy a couple extra bolts for the coolant flange, just in case. They sell them at ECS Tuning for $3.99. It’s such a tight squeeze back there that it’s easy to lose hold of it. I did this job eight years ago (and now need to do it again) and the spare bolts saved me. I dropped one of the original bolts and never saw it again. Couldn’t find it anywhere in the engine bay or on the ground. Having a spare allowed me to press onward without having to order another and wait days for it to arrive.
Outstanding video!... This is a tough job from an access point and your experienced methodical approach is excellent... great narration and very good footage showing every detail... I thank you and am new heading into my garage to do this job and save about $600
Thanks so much for your help! I pulled out the high pressure fuel pump (have you checked your cam follower lately?), the variable timing solenoid valve and the annoying bracket next to it, and the battery for more room around the heater hoses. I couldn't get the upper heater hose off the quick connect so I ended up just cutting it short, leaving the grommet in place and fishing the lower hose up through the grommet. The upper hose is plenty long so if yours is in good shape you might just want to do this instead of buying a new one. It's not that bad a job, just a long slog with all the prep work taking things off to make room, and a lot of reaching and hanging over the engine. T30 mostly some T25, triple square for the annoying bracket, 6mm allen and 10mm hex for the battery and vent, 4mm allen for the fuel line. I think that's it. "needle nose" vice grips for the many hose clips, big and small slots, knife, etc for pulling off hoses. Oh, and the short hose and one of the old heater core hoses makes a quick tool to blow coolant from the reservoir cap hole into the engine for priming! EDIT: oh, I didn't cut the short hose either. It came off the cross over pipe pretty easily, and there's just enough give in the pipe to push the short hose off employing a screwdriver without disconnecting the other hose.. I gave it a shot of silicone and worked it in there first. Not the the heater core hoses: cutting them is definitely the way to go.
This was incredibly helpfully. Thanks for the great write up!! - One thing, at the time I came across this the part linked for the Coolant Flange Hose is incorrect (the one that was cut in half). The correct part number is 06D121101B.
Excellent video. I ended up having to cut the upper hose too. Even cutting it off was very tough. I swear they glued them on. Thanks for being so thorough in your narration.
I did this on my 1.8t before I had the 2.0t...and the 2.0t is 100xs more frustrating. Those spring band clips on the hard pipe hose got me and I didn't order one ahead of time. Would 100% pay a shop to do it for me next time. Hahaha Thanks tho.
I'm gonna be stuck taking my car to some one anyways cause the connector for my coolant sensor rotted from the leak. Been a fun day with the A4. This is supposed to be easier than my 2.7t lol!
You weren't kidding about the hoses liking to stick to the metal coolant pipe lol they were basically demonically possesed! But job done and your video was super helpful. Thanks Champ.
Excellent how-to video! Kudos to you for doing this! Can you please let me know: Is this the same as, or very close to, the A4 B6? I believe I've got this exact issue on an A4 B6 2003 Quattro 1.8 turbo petrol.
I replaced the cooling flange a few years ago using Alldata DIY. Your video and commentary would have been helpful. Later I pulled the head to change the gasket and get some valce work done. And was back there pulling the vacuum pump again. When I swapped my clutch earlier this year, I saw just how swollen the hoses are and need to replace them. Next job on the car. Darnit, anyway. It's a tight spot. I think I'm going to get that ratchet you used. Thanks for the vid.
God damn, so is coolant disappearing but leaving no puddle a symptom for this replacement? Coolant constantly draining from reservoir bit no puddle when parked
Quick question. When your burping the coolant tank why set the blower speed on low? I’ve always set it on high with the heater on. Does it help draw air out of the system better?
Tho I really appreciate the instructions remind me to not work on an Audi if I can avoid it lol side note hoses are fused to everything makes it difficult
Hey yall. I have a problem with the coolant temperature sensor wiring. Theres a open circuit so im trying to follow that hose with the harness on to guide me to do a saulter on my new connection wire. Do yall have any idea where it leads to? I can see the wires but its so tight back there i cant seem to pull it out. Pls help.
you could rename this video "how to replace the vaccum pump and coolant flange on Audi a4 B7". there are no good videos expaining the vaccum pump removal on A4 quattro like you.
Thank you for this video. It has helped me understand and locate my issue and part. I need to replace the heater hose on the flange ( the one with the quick disconnect). Is it possible to pull just that hose through the grommet or do I need to remove everything like you have done in this video? Also, do I need to drain all the coolant do do this one hose?
Great video rookie error on my part I’ve been left with a T30 bolt 🤦🏻♂️😆 I have no idea where it came from lol I’ve got the 3 bolts back in the vac pump and I have the 2 back in the flange lol
Great jobs, very good video and manual.But I think self-locking clamp better than ordinary for screwdriver. I would left original ,self-locking.Thank you for you job.
Hi! I have the exact same car and engine and need to replace all this parts that was replaced in the video such as the coolent hoses and temp sensor with the nescesary o rings, etc. And Wonder if the video maker or someone make the list for me for all this parts that was replaced in this video and link it to me or confirm My list here off the part numbers and parts i got and see if i got everything i need or not? I appreciate asap Answer and help as i need to order all this parts asap as well
How much coolant came out of the hose when you cut it, what type of bucket do we need underneath? (I.e. Tons of fluid, medium fluid or a little fluid) Also, we should do this when the car is cold and has sat right?
I've got an audi a3 2.0 tdi (I know diesel cars aren't popular in US) you still may help me, so the question is, if I want to replace the flange do I need to flush out all the coolant? It will drain anyway if I pull out the part? Or how it's work. Thanks
I'd have a hard time reaching those fasteners and clamps but you made it look somewhat easy. What kind of camera do you use to view around corners? It's amazing that you showed the screw at the back of the head with it. Also, where can I get quality German style house clamps? The ones I tried fell apart when tightened. Thanks for another great video.
Geo Logic I’m using a IPhone 8 to get back there. You use the screen as a viewfinder so you can see what your filming. For the clamps I get them from Worldpac.
Great video. I’ve done the vacuum pump rebuild previously and that was a bear. Housing needs to be replaced now roughly 20k later. Looks like a lot of shop time to get this done.
*what will happen if that metal bracket doesnt get bolted back in place let's say it hangs loosely with the wires attached to it? Asking because mine is currently in that state and it may or may not be causing an issue I'm having so just wanted to know*
I've never filled the cooling system that way, instead, clamp off the little line to the reservoir remove the 10mm plug on the cross pipe and burp the system by placing a wet finger over the hole on the cross pipe, lifting as I squeeze the large hose on the reservoir and placing it over the hole as I release. This pumps out all the excess air up high in this closed cooling system. You are done when coolant without bubbles comes out of the port. Reinstall the plug.
@@midnightboymcsince we are all commenting every 2 years I’ll comment. I just did this….I lost the retaining clip on the heater hose, I broke the vent hose, some wire is exposed on one of the coolant hoses cuz blah whatever. So $40 for the flange housing thing, $10 or something for the clip, $15 for the breather hose I shouldn’t have broke, $25 for the triple square bit set. And hopefully nothing else….I really hope there’s no plastic shrapnel in the hoses now cuz that’s why I’m changing the flange thing. It broke.
Heater hose connector in the 15:21 minute mark, you named it "the pipe". Mine broke off . Which is why I have struggled to get to this video. You reached the closest of them all. That pipe broke and all of my coolant was gone in an instant... I was able to get a 5 quart of coolant on my way home just to get home. Found that the hose was okay except for the broken pipe it was still attached inside the hose. I don't know how to remove this part. It is really stuck or something. I managed to pull up the little metal lock clip thing but it still doesn't free up. The hose portion is perfectly fine because the nipple part of the pipe broke. Have a proper name for that pipe housing? I can't get a name for it anywhere else. I will need to replace that peice.. Thank you so very much.
Hello I have a 2000 Audi A6 Quattro and I’m having coolant leak issue that caused my car to over heat. The leak is toward the back of the engine/transmission and not the reservoir. Does this mean I need to replace the heating core hose?
K Burn1 Most likely not heater core. On the back of the cylinder head there’s a coolant flanges where the heater hoses go to that is probably the leak. It’s probably leaking because of an oil leak that caused the leak to look into that also.
How to Automotive every b7 owner I ran into has added some sort of gasket maker around it to seal it more. I’m rebuilding a 07 2.0t motor I pulled from an avant- for my sedan and I noticed when I took off the flange it had the grey silicone around the hole where the o ring sits.
i had to stop and put everything back as I couldn't remove the stupid hose off and didn't have a triple square 5 mm bit, I just ordered one as well as the coolant hose clamp plier. It's pretty tight.
Just did this and the video is great (though as noted one hose is incorrect and another is missing from the list) Previously I rebuilt the Vacuum pump and replaced the rear timing chain and tensioner, I looked at the flange and hoses and they were fine (no leaks/swelling) Sure enough three months later it started leaking! As others have noted the hoses tend to 'weld' themselves to the steel pipes so just cut them as getting the clamps off is a bitch, the only tool I wish I had was the remote style of clamp compressor (the one with a long cable ) as getting at them is a bigger bitch LOL.
So.. Basically its easier to rob a bank, buy a new Audi and just throw your old piece of shit in the trash. Better yet, don't ever buy this piece of shit unless you've got too much money and need to throw some away.

No. It only feeds the brake booster

I've never filled the cooling system that way, instead, clamp off the little line to the reservoir remove the 10mm plug on the cross pipe and burp the system by placing a wet finger over the hole on the cross pipe, lifting as I squeeze the large hose on the reservoir and placing it over the hole as I release. This pumps out all the excess air up high in this closed cooling system. You are done when coolant without bubbles comes out of the port. Reinstall the plug.
Lol I can't do this 😭
Yes you can!
@@midnightboymcsince we are all commenting every 2 years I’ll comment. I just did this….I lost the retaining clip on the heater hose, I broke the vent hose, some wire is exposed on one of the coolant hoses cuz blah whatever. So $40 for the flange housing thing, $10 or something for the clip, $15 for the breather hose I shouldn’t have broke, $25 for the triple square bit set. And hopefully nothing else….I really hope there’s no plastic shrapnel in the hoses now cuz that’s why I’m changing the flange thing. It broke.
@@Mike-we3rbsame, it just blew apart randomly when I was parked with car running
@@Mike-we3rbI also broke tf out of the breather hose, he said he careful these break a lot, paused it then proceeded to snap it in half
@@pwindThose breather hoses are pretty brittle as they get older, that’s for sure. Especially if you’re doing this job in cold temperatures.
Heater hose connector in the 15:21 minute mark, you named it "the pipe". Mine broke off . Which is why I have struggled to get to this video. You reached the closest of them all.
That pipe broke and all of my coolant was gone in an instant... I was able to get a 5 quart of coolant on my way home just to get home.
Found that the hose was okay except for the broken pipe it was still attached inside the hose. I don't know how to remove this part. It is really stuck or something. I managed to pull up the little metal lock clip thing but it still doesn't free up.
The hose portion is perfectly fine because the nipple part of the pipe broke.
Have a proper name for that pipe housing? I can't get a name for it anywhere else. I will need to replace that peice..
Thank you so very much.
So I noticed that you don't reply to your viewers questions.
Can someone help me. Thanks in advance.
is it ok not to bleed the heater core and cooling system?
What if installing the coolant flange continues leaking? Mine seems to be leaking from the top of the heater hoes any advice on what it could be?
Do you have a list of part numbers for this job? Thanks
There are affiliate links for them in the description of the video.
whats the flag time for this job
Milwaukee's new tools are for sure coming September everywhere ? I wanna save my money
nipplemilk Network yes they will be out in September!! I’ll be doing reviews on the channel so stay turned for that.
How to Automotive you bet , only place to go for reviews
Hello I have a 2000 Audi A6 Quattro and I’m having coolant leak issue that caused my car to over heat. The leak is toward the back of the engine/transmission and not the reservoir. Does this mean I need to replace the heating core hose?
K Burn1 Most likely not heater core. On the back of the cylinder head there’s a coolant flanges where the heater hoses go to that is probably the leak. It’s probably leaking because of an oil leak that caused the leak to look into that also.
What does a job like that cost
Why wasn’t any silicone added around the seal?
Project A4 it’s not needed. They don’t use it from the factory.
How to Automotive every b7 owner I ran into has added some sort of gasket maker around it to seal it more. I’m rebuilding a 07 2.0t motor I pulled from an avant- for my sedan and I noticed when I took off the flange it had the grey silicone around the hole where the o ring sits.
Just did this job lol. Wish Audi would give us a removable access panel by the battery compartment/firewall
i had to stop and put everything back as I couldn't remove the stupid hose off and didn't have a triple square 5 mm bit, I just ordered one as well as the coolant hose clamp plier. It's pretty tight.
Yes it’s tight back there. Hopefully it all works out for you. Thank you for watching!
I did it everybody!!!!
That brake part(new) was already oily . I didn’t “oil” the gasket ring. Was that ok? Didn’t have oil with me
The links to the hoses don't work
Just did this and the video is great (though as noted one hose is incorrect and another is missing from the list) Previously I rebuilt the Vacuum pump and replaced the rear timing chain and tensioner, I looked at the flange and hoses and they were fine (no leaks/swelling) Sure enough three months later it started leaking! As others have noted the hoses tend to 'weld' themselves to the steel pipes so just cut them as getting the clamps off is a bitch, the only tool I wish I had was the remote style of clamp compressor (the one with a long cable ) as getting at them is a bigger bitch LOL.
So.. Basically its easier to rob a bank, buy a new Audi and just throw your old piece of shit in the trash. Better yet, don't ever buy this piece of shit unless you've got too much money and need to throw some away.
Bingo
