I followed your video and replaced the thermostat and water pump on a C7 A6. Thank you kindly for the easy-to-follow video. As a hobbyist, it took 16 hours as I got stuck on a few of the technical parts. Well worth the experience and extremely satisfying.
Yea it’s not a fun job I can tell ya that, I feel like this gentleman has done it a few times and the only thing I could add is throwing some tape around that triple square to keep your wrench where you’d like it when removing that pulley, other than that I learned how to do it from this video!
@@FelekPL You have to drain the coolant to do this and disconnect both radiator hoses because there's not enough slack in the hoses to "just slide it forward".
I just did this job on my wife's B8.5 S4. A few notes: on the B8.5, the water pump pulley bolts are a different size (bigger). Belt routing is different due to it having electric steering. This video totally ignores the driver side crossover pipe bolts, which are a real bear, though you only need to take one-off. Also, they didn't do the water pump - a big mistake in me following this video regarding that. Even though mine didn't look like it was leaking, the system wouldn't hold pressure when vacuum was hooked up. Ended up being a bad pump; cost me an extra $40 because I picked it up locally (B8.5 also uses a different pump with a vacuum hose on it, so B8 pumps won't work on it). Also cost me a few extra hours of frustration. You should also replace the intake gaskets as well when doing this job; $15 and 5 minutes. The vacuum line labeling was unnecessary. A simple close-up picture was all I really needed and I didn't even look at my labels. The breaker bar in the video for removing the belts is a must, especially for the supercharger as the clearance is super tight - any normal socket/breaker bar setup would be too wide to clear the fan housing. The air ratchet in the video is totally unnecessary and would have been harder to do IMO.
Excellent video - the few 'how to' I create are just title cards, no narration, and a bit of musical jokes from the foxtrot orchestra I play in. Title cards like your on screen notes show what to done and then pictures show the steps. I can hardly stress enough the pleasure of going through this video instead of unorganized, iffy photography, and needless commentary. What I have learned from this is that the design is not created for 'ease of maintenance' and despite the really complex car repairs I have done - hard pass on this one. But it as a great source of information for those who have this issue to understand all the steps and why it costs so much when on most cars, the thermostat replacement is easy enough that the beginner can do it and gain confidence to go on to the next repair. Many thanks.
Working on late model cars is so much nicer than working on 50-60 year old cars that have been neglected for decades. But, the old cars once brought back are SO much easier and more direct when it comes to any repairs. These late model cars are engineered like crap. All the plastic and rubber components will em brittle and create a never ending cycle of failure after failure. Replacement parts will have to be cobbled together as OEM plastic and rubber pieces will be non existent. Pure junk.

Great video, Audi technicians can learn something.. good job !!!I understand that dismount the front complete is more easy for reach the thermostat, but extremely more expensive. I paid 800 Euro for the same work in Audi..
Hi Derek Thankyou for a really champion instructional video. Spot on. It certainly dispels any illusions about it being an easy job. But approached methodically with your cool calm style, labelling etc., and with those two special tools then it looks doable. My dumb question is: so why do you need to take the water pump pulley off to replace only the thermostat which is sitting on top of the block? Is it that normally you'd replace both pump and T.stat together right? Also with GDI inlet port coking, in your experience what mileages are you seeing with the 3T engines before it becomes a maintenance problem? Thankyou again Derek.
5 years later I have the same question . currently have front bumper and supercharger off to do other maintenance and wanted to change thermostat only since i had waterpump done by a shop some time back.
Great Job Derek! I just wonder why not put the car in service position...I always do just to work in comfort and have visibility, even the Q7 I put in service position I dont like working blind to be honest. I think Audi service position is one of the best things Audi engineers did. For bigger jobs I just get rid of the whole front end.
Derek you are spot on with this video. I thank you for it it's cool to put a car in and what your doing to it comes up and shows you on the car your doing not something like it. so again thanks.
I was wondering if it's the same procedure to remove just a water pump my water pump started leaking and making noise. Unfortunately I can't find any videos on replacing the water pump. I hope I don't have to remove everything you did? Great video keep up the amazing work
359alex Yes, the procedure is more or less the same. Most of the DIY write ups in my notes (see description) explain the water pump removal. I believe you must go a bit further to get it off.
Best video ive seen on a 3.0t. Do u have to change the super charger gasket eveytime u disassemble the supercharger? Or if they r only 6 months old, u can use them again?
official procedure always says replace, but you can get away with it if they're 6 months old like you said. If you have removed enough to see the orange gaskets 100% replace them because that's already lots of personal hours or thousands of dollars if you're seeing those. injector seal kits are cheap, the little metal bracket they have is supposed to be one time use if it pops out ever.
What a video! Was looking for this video for a B8.5 RS4 (V8). I'm thinking I need to remove the bumper and radiator to do this job. Maybe some knows? Well done Derek on such a profesional video which will help many people :-)
Great video!! Any idea on how to get the pcv out? I just need to get to the four screws under that black water pipe running north to south. No idea on how to get it out.
Great video man!! But can u make a video on how to get the air out the coolant system after using purge/refill tool. 🙏🏽 i know it’s defrost on, open SC bleeder screws and loosen the inlet heater core hose until coolant shoots out. But there’s no videos of this o/l!!
Great video! I've got a 2016 A7 and after changing the water pump and thermostat, I need to know how to set the flaps that everyone talks about. I put the supercharger back on and everything works except the car has no kick and the check engine light comes on. Everything I have read says it is the intake manifold flaps.
I had a 3.2 (similar down there) and didn't do that right, even though I lined it all up. The issue is that it sits high on the gaskets and tightening the screws pushes flap to wrong side. . The flaps can be manipulated on the outside of the engine where the device that moves it is. Hard to describe. But move the arm a bit and push down on the lower intake to set it in place and tighten screws while holding down. Check by moving the flaps. It throws a code if you mess up and do it wrong.
Wonderful info!! A6 Avant with a coolant leak underneath the supercharger, which I have just removed ( thanks to you ) & Iam not sure where it is coming from? It has to be from the Thermostat or the return pipe, correct ? Would removing the fan assembly help with the tight room needed to remove those bolts from hell ?
Patrick Hickey - google how to put the front into “service mode”, it’ll give you a few extra inches of workspace. Change all gaskets, hoses, t-stat, maybe even water pump. Best to replace as much as possible while the supercharger is off.
hi, thank you for good video, i have a question - whats the motive to change the thermostat? my Tuareg hybrid supercharged have heat engine, and the re-tour from radiator is cold, i think the thermostat is blocked in close position and not have the circulation of cooling liquid in big circuit...
moldpatriot I was overheating. Fan noise was audible in the cabin from outside. No lights or codes told me it was the T-Stat, as it is a mechanical part.
ok, the thermostate change has resolve the problem? you don't have overheating after replace? take a beautiful song "Peace Song" from Russian Orthodox Church- ua-cam.com/video/lvaoOfPQxZ8/v-deo.html
Erick Bren don’t force it. Somethings wrong as I could use one finger on that tensioner. Make sure you are turning clockwise and belt is loosening before applying pressure. Belt should give just enough to pry over the lip of the pulley.
Please if you have a video diagnostic the ac system and replace all the ac system. Dealer had inspected it but they dont know what going on with it. Brought it in a few local mechanic shop but they replace the compressor, climate control, pressure switch, every shop they inspect it and they recharge the ac gas which is everytime cost 153-187 us dollar for just recharge a gas to check for the compressor kick on, not include check leaks. They keeping giving a bills of doing things. I just got them replace the compressor, cost $1386 include recharge but it still not working. They end up telling me to drop the car and pay for at least 4 hours more to dive into but they are not warranty and could cost more hour to do, they will lmk when 4 hours up. But they couldnt find any problem.
I ordered same vacuum machine after watching the video, I installed bigger heat exchanger on B8.5 S4 , and cant get the air out, I hope this will do the job. Thanks
Did using the vacuum tool end up working for you? I'm in the same position - larger heat exchanger, and think I might have air stuck somewhere, even after manually bleeding. Did you bleed the system with some coolant still in the engine?
This video would be half as long if this guy handled the car like a damn MAN! Lol, just messin. I DO like the wooden handle trick though, took me a few R&R's before doing the same thing with 3/8 extensions. I worked on these cars for about 8 years, EVERYTHING is under that damn supercharger. We got really good at removing them at the dealership. My best time for supercharger removal was 7 minutes.
A helpful tutorial, I like it. But I need to buy a lot of tools if I own a such Audi S4 when I need to replace something. Maybe 1 or 1.5 thousand yuan or even more I would spend for the tools in my country.So It s a good idea to do a replacement by myself.Because aftermarket service is very expensive in my country especially a BMW / Mercedes /Audi or some car like that.
Devlin Kennedy Im actually doing this tight now and got stuck in that part ... not sure how to remove the front pipe that connects to the thermostat 🤦🏻♂️😒
hey derek my 2013 s5 t stat needs to be replaced the mechanic qouted me 7 hours total do you think thats accurate,,btw my s5 has the same 3.0 tfsi supercharhed engine thnks
@@DerekHunziker thank you for your reply another question is i want to upgrade my intercooler to apr will it come with new water pump and thermostat or i will still need my oem ones first
@@DerekHunziker thank you for your help i will just let audi replace my thermostat and water pump on my s5 oem parts and then upgrade to apr quite costly do they normally just break after around 50k miles or does it depends from car to car and the way you drive the car as well, water pump seal went and they putting new water pump in and housing went on thermostat is that why my fans were not coming on
Great informative video but I notice Audis require way more work to do simple maintenance compared to other manufacturers. There are way more things that you have to remove to get to parts that are more easily accessible on most other vehicles.
They seem to do this deliberately so that owners will take their car to the dealer. A simple drive belt replacement which should take 10 minutes takes all day in my S4, and that's if you already know how to do it. If you don't - 2 days. You need to disassemble the front of the car, drain the coolant, disconnect the radiator hoses and pull the radiator frame forward about 3". It's called "service position". All so that you can get your hand down there to get at it. It's insane. Getting at the A/C compressor is even worse. Working on many things requires an engine pull.
FarmersAreCool, it’s special, but you can pick up a kit online very cheap. If you put the car into service mode, you can probably reach down with a standard socket extension.
I'm not sure, the T-stat only controls flow and is not connected electronically, so I assume temperature is measured elsewhere. I'd ask on an Audi forum if I were you.
mark parawan I would not do this work preemptively, unless there’s a chance you could be stranded far from home/shop without a tow. The less you touch these cars, the better.
The replacement period for thermostat in older Audis was 60 K miles. I would replace that at max. 90 k miles, so my car will not let me down. I think the best to go with OEM parts always.
Hi Derek, i have a 2011 S4 3.0TSFI and it happen to be losing coolant every time i drive out a few kilometres, strangely the car have no physical leaks around the engine but i noticed a bit of steam on the exhaust when idling. What do you think can be the problem? Is it a thermostat fail? A coolant pipe leak? A supercharger coolant leak? Or top gasket leak?
try the water pump, a fairly cheap fix. same thing from the sound of it happened to me, water pump would leak small to large amounts of coolant after druving.
It’s the lower left end of the front coolant pipe (aka pipe from hell). I didn’t end up detaching the pipe fully, just loosen enough to pry back and clear the thermostat connection.
Anybody had a major coolant leak when filling the reservoir at the end? I can’t see where it’s coming from, but suspect it’s coming from the little elbow piece under the supercharger.
BigFords1 - For the first couple days, I had to top off the coolant a few times. I was worried it was a leak, but it wasn’t and I’ve had no leaks for several years after this.
This is a major leak. Not just drips but full on flow. It dumps on the ground as fast as I pour it in. PS. Awesome video. Very helpful. Mine is a B8.5, and there were some subtle differences, but this video was a lifesaver.
BigFords1 just think of it this way - now you have double the experience! For real though, I’m glad you were able to identify the issue. I’ve heard horror stories about impossible to find leaks.
It takes a big man to admit that in public. But I've done similar... like the time I dropped an air filter box clip down the intake to the turbo on my VW. Sounded like a ghost. Had to do a full turbo install. Twice... because I missed a washer on the innermost oil line washer. It's the little things...
Nun ja, es hört sich so an, als hättest du eine "coole" Herausforderung gehabt, als du versucht hast, diese Kühlmittelleitung zu überwinden! Aber hey, zumindest hast du jetzt eine neue Fähigkeit, die du in deinem Lebenslauf hinzufügen kannst: Experten-Thermostat-Bändiger!
Hi Ken, the top of the T-Stat is connected to the front coolant pipe. At 22:50 and 24:30, I am removing the left most sets of screws on the front coolant pipe, leaving the right ones still connected. This allows you to pull the front coolant pipe back far enough to disconnect the T-Stat (see 25:35). The front coolant pipe is the hardest part of this job.
thank you for the reply Derek, appreciate it. another question, is it necessary to use the the air gun to remove that bolt? because i do not have air tool.
@@DerekHunziker thank you Derek…one more question on these screws…there are 2 at the left end of the crossover coolant pipe, One center smaller T 25 torx screw where the coolant pipe enters the thermostat I am wondering if you can just loosen the screws as far as possible or do you have to completely remove them? Thank you.
@@donaldnesbitiii7990 I haven't tried with them just loose, but it seems like it's worth a shot. The last thing you will want to do in life is mess with this coolant pipe.
Well most shops charge $100-130 an hour and there are so many things you have to remove to get access to what needs to be replaced so... $$$$ A person brought me his S4 because I'm going to swap out his pump and t-stat for only $400 labor.
I guess there are trolls everywhere. This was an amazing video. Very helpful for DIY guys and gals out there. And really great that you took the time to share. I've removed the intake on my 3.2 a bunch of times and those clips at the back are definitely a challenge. You make that part look easy. The big mystery... how do you do all that with not one profane word? Cheers.
Anybody doing this job (or anything on an Audi) I highly recommend these: VIM stubby torx www.amazon.com/Vim-HCT1050-10-Piece-Half-Cut-Driver/dp/B000VUM6BU And these VIM stubby triple square www.amazon.com/Vim-Products-VMXZNS412-Subby-4Mm-12Mm/dp/B003TSMR38/ref=mp_s_a_1_3?dchild=1&keywords=vim+stubby+triple+square&qid=1589915759&sprefix=vim+stubby+&sr=8-3 No joke, I used these, professionally, EVERYDAY
I followed your video and replaced the thermostat and water pump on a C7 A6. Thank you kindly for the easy-to-follow video. As a hobbyist, it took 16 hours as I got stuck on a few of the technical parts. Well worth the experience and extremely satisfying.
Hats off!!, not a single word but effective and easy guidance, not to mention thorough work. Thank you!!
Had my thermostat go out yesterday. After watching this - paying the mechanic was the smartest thing I could do. Thanks for the great video!
I just came to this same conclusion
Yea it’s not a fun job I can tell ya that, I feel like this gentleman has done it a few times and the only thing I could add is throwing some tape around that triple square to keep your wrench where you’d like it when removing that pulley, other than that I learned how to do it from this video!
This guy deserves a million likes.
No kidding right? He just saved me $2200! Derek, you are a lifesaver. Thanks man!
Nice video! Looks like removing the front bumper and sliding radiator out would make this process much easier
@Bob Saget on A4/S4 it's actually pretty easy to slide front out, you just need 2 longer bolts. He would probably save time
@Bob Saget by "sliding the radiator out", I think he meant pulling it forward... otherwise known as Service Position.
@Bob Saget Sliding the radiator out is exactly what service position is, and when you know what you're doing, it takes like 10-20 minutes tops.
@@FelekPL You have to drain the coolant to do this and disconnect both radiator hoses because there's not enough slack in the hoses to "just slide it forward".
As I study the Audi cars Audi should get a reward for the most work needed done on a car in such little time or mileage

cris boss I’m not sure on that - I’d give APR a ring - I doubt it comes with a new T-Stat.
@@DerekHunziker thank you for your help i will just let audi replace my thermostat and water pump on my s5 oem parts and then upgrade to apr quite costly do they normally just break after around 50k miles or does it depends from car to car and the way you drive the car as well, water pump seal went and they putting new water pump in and housing went on thermostat is that why my fans were not coming on
Great informative video but I notice Audis require way more work to do simple maintenance compared to other manufacturers. There are way more things that you have to remove to get to parts that are more easily accessible on most other vehicles.
They seem to do this deliberately so that owners will take their car to the dealer. A simple drive belt replacement which should take 10 minutes takes all day in my S4, and that's if you already know how to do it. If you don't - 2 days. You need to disassemble the front of the car, drain the coolant, disconnect the radiator hoses and pull the radiator frame forward about 3". It's called "service position". All so that you can get your hand down there to get at it. It's insane. Getting at the A/C compressor is even worse. Working on many things requires an engine pull.
What are all the parts needed to replace t stat
Long strongarm with a 17m socket do or is that tensioner tool something special ?
FarmersAreCool, it’s special, but you can pick up a kit online very cheap. If you put the car into service mode, you can probably reach down with a standard socket extension.
Thanks for the knowledge.
Well after replacing thermostat what happened to own Dependable cars thermostats never went bad unless for some reason the car was overheated
Brother, where did you get that breaker bar to remove the supercharger tensioner?
It’s a harbor freight tool, www.harborfreight.com/serpentine-belt-tool-kit-63689.html?cid=paid_google%7C%7C%7C63689&gclid=EAIaIQobChMIs5eGju2l6gIVUhx9Ch2DJg3PEAQYAiABEgJAxPD_BwE
Hello I wanted to know where the coolant temperature sensor is thx.
I'm not sure, the T-stat only controls flow and is not connected electronically, so I assume temperature is measured elsewhere. I'd ask on an Audi forum if I were you.
Is the water pump an easy replacement while in this far?
Kaleb Speck, if you remove the front coolant pipe completely and are in service position, yes, it would be easy.
did you only loosen one side of the front coolant pipe ?
audi5inline Yes, just enough to disconnect it. That thing was my worst nightmare - best to touch it as least as possible due to hidden bolts
I love the zip tie work at @16:55
When should you change out the thermostat before it breaks?
mark parawan I would not do this work preemptively, unless there’s a chance you could be stranded far from home/shop without a tow. The less you touch these cars, the better.
The replacement period for thermostat in older Audis was 60 K miles. I would replace that at max. 90 k miles, so my car will not let me down.
I think the best to go with OEM parts always.
Excellent job... Thanks!
Anyone know where i can find a guide for a B8 1.8T or is the procedure the same?
completely different motor, every component is arranged differently. If you have to ask this question I recommend you not do this yourself.
What is the cost to have an indy Audi specialist do this?
LiberalD2 I was quoted ~6 hours of service and you will also need to factor in the cost of parts (gaskets, t-stat, coolant, etc.)
Isn't the part where you have to loosen the supercharger pulley belt missing?
Nice content though.
Hi Derek, i have a 2011 S4 3.0TSFI and it happen to be losing coolant every time i drive out a few kilometres, strangely the car have no physical leaks around the engine but i noticed a bit of steam on the exhaust when idling. What do you think can be the problem? Is it a thermostat fail? A coolant pipe leak? A supercharger coolant leak? Or top gasket leak?
try the water pump, a fairly cheap fix. same thing from the sound of it happened to me, water pump would leak small to large amounts of coolant after druving.
Great job to remove supercharger, but I would put the front end to service position to remove belt.
What's being removed or unscrewed at the 24:30 mark?
It’s the lower left end of the front coolant pipe (aka pipe from hell). I didn’t end up detaching the pipe fully, just loosen enough to pry back and clear the thermostat connection.
@@DerekHunziker thank you!
2010 a6 3.0 no coolant fans unless a/c is on any idea
Anybody had a major coolant leak when filling the reservoir at the end? I can’t see where it’s coming from, but suspect it’s coming from the little elbow piece under the supercharger.
BigFords1 - For the first couple days, I had to top off the coolant a few times. I was worried it was a leak, but it wasn’t and I’ve had no leaks for several years after this.
This is a major leak. Not just drips but full on flow. It dumps on the ground as fast as I pour it in.
PS. Awesome video. Very helpful. Mine is a B8.5, and there were some subtle differences, but this video was a lifesaver.
I didn’t tighten the thermostat bolts... none of them. Not even hand-tight. Someone please come take my tools from me. I am not worthy!
BigFords1 just think of it this way - now you have double the experience!
For real though, I’m glad you were able to identify the issue. I’ve heard horror stories about impossible to find leaks.
It takes a big man to admit that in public. But I've done similar... like the time I dropped an air filter box clip down the intake to the turbo on my VW. Sounded like a ghost. Had to do a full turbo install. Twice... because I missed a washer on the innermost oil line washer. It's the little things...
Hi where is the coolant sensor located?
Here: docs.google.com/document/d/1O-ns_VjaGBMf6pI4X6suxLJHtIX42DxInZs7AMNGlFU/edit?usp=sharing
Putting the front end in the service position gives tons more room to work.
Also bei mir war die Kühlmittelleitung über dem Thermostat ne andere richtig beschissen rauszukriegende
Nun ja, es hört sich so an, als hättest du eine "coole" Herausforderung gehabt, als du versucht hast, diese Kühlmittelleitung zu überwinden! Aber hey, zumindest hast du jetzt eine neue Fähigkeit, die du in deinem Lebenslauf hinzufügen kannst: Experten-Thermostat-Bändiger!
That looks hard without removing the front bumper cover.
do you have anyway I can contact you I need your help
ALUMNI2K DM me on Twitter @dthunziker
what is the purpose of removing 2 screws @ 22:50 and 24:30?...then the frame jumps to 24:50 of removing 6 screws for thermostat.
Hi Ken, the top of the T-Stat is connected to the front coolant pipe. At 22:50 and 24:30, I am removing the left most sets of screws on the front coolant pipe, leaving the right ones still connected. This allows you to pull the front coolant pipe back far enough to disconnect the T-Stat (see 25:35). The front coolant pipe is the hardest part of this job.
thank you for the reply Derek, appreciate it. another question, is it necessary to use the the air gun to remove that bolt? because i do not have air tool.
@@DerekHunziker thank you Derek…one more question on these screws…there are 2 at the left end of the crossover coolant pipe, One center smaller T 25 torx screw where the coolant pipe enters the thermostat I am wondering if you can just loosen the screws as far as possible or do you have to completely remove them? Thank you.
@@donaldnesbitiii7990 I haven't tried with them just loose, but it seems like it's worth a shot. The last thing you will want to do in life is mess with this coolant pipe.
This is f*cking ASMR
Nice...respect
Just dropped my s4 off at the shop to have thermostat replaced quoted $457 I don’t wanna no how much Audi would of charged me 🤔
Well most shops charge $100-130 an hour and there are so many things you have to remove to get access to what needs to be replaced so... $$$$ A person brought me his S4 because I'm going to swap out his pump and t-stat for only $400 labor.
Your torque specs or off bro
Kevin Garcia - whereabouts?
Even the child no that's painful and they feel your pain wow
Did you really put plastic wrap over intake manifold ports???
No, I used genuine OEM Audi 2mm intake manifold plastic, you fool. Only rookies use plastic wrap.
I guess there are trolls everywhere. This was an amazing video. Very helpful for DIY guys and gals out there. And really great that you took the time to share. I've removed the intake on my 3.2 a bunch of times and those clips at the back are definitely a challenge. You make that part look easy. The big mystery... how do you do all that with not one profane word? Cheers.
thanks a lot
Good video!
Contrasting color permanent marker. (Grey or white if not then painters tape
25:48 I cringed hard when you filpped the part and the sand from it fell into the coolant
Yeah, total facepalm. Took me forever to clean that out. Lesson learned for sure.
Straight heart surgery
What a nightmare!
No kidding
My thermostat has gone bad. I’m about to just trade in the damn thing...
Anybody doing this job (or anything on an Audi) I highly recommend these:
VIM stubby torx www.amazon.com/Vim-HCT1050-10-Piece-Half-Cut-Driver/dp/B000VUM6BU
And these VIM stubby triple square
www.amazon.com/Vim-Products-VMXZNS412-Subby-4Mm-12Mm/dp/B003TSMR38/ref=mp_s_a_1_3?dchild=1&keywords=vim+stubby+triple+square&qid=1589915759&sprefix=vim+stubby+&sr=8-3
No joke, I used these, professionally, EVERYDAY
hold on now, all this for a thermostat? wow.
go check out the carbon cleaning and pcv diy for the same engine 3.0tfsi lol :)
I don't no what's wore's brain Surgery are working on a Audi My God all that for a Thermostat no wonder the price is as munch as a brain Surgery damn
I drive a passar 2012 now and this is my first and last VAG car. Fckn idiot engineer, everything is so difficult to replace on this idiot cars
This guy lost all my confidence when he turkey bastered the coolant reservoir.
This is also why everyone in my family skips the Turkey gravy on Thanksgiving
It's like watching a mute video, I don't like it. thumbs down👎
