Wow! This was a life saver. BOTH Haynes & Bentley have this WRONG! FYI if you are really careful a 4mm Allen will work for the triple square (my triple square only goes down to 6mm). Thanks so much. Wish I worked that fast.
LOL...the speed is in the editing! Thanks for watching & thanks for the 4mm tip!
Thanks for the video , I think I am going at audi to do this... cant believe all the work u need to do for a thermostat
+Super bitch Thanks for watching & taking the time to comment! Let me know how things went.
My Thermostat code has came over a year ago , the temperature gauge come to about 75 C .. on a hot day it will go to the regular 90 in the winter stays at 75 ... car runs fine the check engine come s and goes every now and then ..i was thinking changing it but now i see it cost about 700$ at Audi. Do you thing this is a must fix or it can wait?
Super bitch A thermostat that opens early / stays open too long can affect fuel economy... if that is all it does, then it is not that big of an issue and can be left for a while longer. If it were to stick / stay closed all of a sudden, then you will run into overheating issues... which if not caught in time, can / will cause bigger problems. At minimum keep a close eye on things!

Thank Thomas! I will be keeping an eye on it :)
Nice work sir I like how you used a piece of latex glove to w
Thank you for watching!
This video is really great thank you so much and I do understand putting your name on it so people won’t steal it or use it but it would be nice if you could put it up just a little bit higher because it was hard to see some of the things that you were pointing out with your view because the words are on the way thank you though for taking the time and making this such very appreciated
Thank you for watching... it will all make sense when you are looking at your car... no watermark when looking at your own car. =)
if you have one of these to replace my intake cam on my 2.0T due to follower failure that would be awesome , I find these vids outstanding.
+Clive Young Sorry... not yet.
thanks for the vid alldata is down and i have to do this tonight for one of my customers
+lgonzalez1154 Thanks for watching! Let me know how it went... I'd be interested in feedback from another Tech!
+Thomas EXOVCDS no prob budd will do it doesnt look too difficult im hoping it only takes me 45mins i have a couple other projects to tend to.... 2011mustang gt i already installed a pro charger tonight i have to complete the independent fuel system the customer wanted so its gonna be a late one
+Thomas EXOVCDS by the way love i love the silicone over the o ring i thought i was the only one
Great video. I hope you are well.
Thank you for watching... yes, I'm doing fine thanks!
Mine leaked right after this and it was due to my own fault . posting this comments so others don't do the same mistake. I kept seeing coolant above the drivers engine mount. took it all apart and discovered my error . the hard pipe that has the oring in it goes in first against the thermostat. then the other small verticle pipe , then the torx screw into the thermostat. I made the mistake of putting the other pipe first then the coolant pipe. the oring in the coolant pipe does not seat properly if you do them in the wrong order. as the bracket for the coolant pipe is further away from the stat causing it to not seat the oring properly. Not a big deal and cost me a couple of hours and more coolant .. all good now.
+Clive Young Good info! Thank you for sharing!
Great video! What size triple square did you use? I got all the way to the triple square and had to put it back together. Luckily mine is stuck open so it isn't causing any major concerns ,yet. I should get it taken care of before it is too late.
+dan hed Sorry... I don't think I paid attention to what it was (I have a 10 piece set and use what fits): public.snapon.com/R_RRD/Objects_lg/images/BLPXZNM389.jpg
Hey Thomas.. Great vid.. Hoping to tackle this over the weekend and I'm looking for the correct thermostat. I have the same motor. I've been looking up parts and notice that some of the thermostats have a complete housing with a thermostat unit bolted to it and others have what looks like the housing and thermostat all in one with no bolts/screws on the housing. Is there a difference? Thanks in advance.
+Dave Mitchell The one with the housing, the thermostat can not be removed from the housing... the two are for different versions / setups / production cross-over. Phone the dealer, give them your vin# and get the correct part number (should be different) for your thermostat... then you can google for best price.
+Thomas EXOVCDS Thanks a bunch Thomas.. cheers!
+Thomas EXOVCDS what's the trick to get these electrical connectors off?
Dave Mitchell Push the connector towards the component... while applying pressure, pull back on the release tab & pull the connector off of the component.
+Thomas EXOVCDS holy shit.. thanks for the quick reply..
When you were down there replacing the Thermostat, do you remember seeing the knock sensor (G61) , getting a code for it and thinks its down there under the intake, but not sure
thanks.. if you know
Yes, knock sensors are under there.
Thomas, as a non-mechanic I was able to replace my 2007 A4 B7 Quattro thermostat a while back using your instruction video, it worked perfectly. Thanks so much!! I have to go back in now and replace the oil filter housing gaskets as they're beginning to leak.
I would love to swap out the torx and triple square bolts with hex this time as you suggest. Is their a way to find out which which hex sizes I would need prior to doing the repair? I've checked online and in the service manual but haven't found the sizes yet. Is there like an aftermarket hex bolt kit that might have everything I need. Thanks again!
Just remove one of all the sizes and then measure the thickness of the threads & the thread pitch. Most hardware stores should have hex bolts that will match-up.
How much should this repair cost? are there any labor savings if it is done at the same time as the timing belt? thanks for your input.
+Spaghettipolicy Cost will vary from shop to shop... labor rate should be similar (but there can be unexpected issues that add extra time). Timing belt is separate cost and wouldn't save much aside from the cooling system being drained already to do the water pump. Sometimes it costs what it costs... will be cheaper than a timing belt failure repair (always keep that in mind).
Hey Thomas. Great videos! I have 2006 2.0T fsi Jetta. Do you know the exact location were the radiator/coolant fan switch is at? The switch has triangle shape connector on one end.
Eldan Smartlowit I'll see what I can find... will get back to you tonight or tomorrow some time.
Eldan Smartlowit North american car or a euro version?
Eldan Smartlowit You should have a variable speed fan assembly... which is controlled by the ECM. take a picture of your rad fan and send it to me fkh161@fkh161.ca
***** North American
Thomas....is there ANY type of warning sign that a timing belt needs to be replaced?? I also have a P2181 issue and was looking at your vid to see if I could do it. No way!! That's why you guys get paid! Thanks man.
+Brandwhack Small cracks in the top surface if you are lucky... missing teeth is also a sign. Always replace earlier than too late.
Do you recommend getting OEM replacement parts or is an aftermarket thermostat and sensor ok. What kind of replacement parts did you use if I may ask?
Buy from a parts supplier that specializes in VW / Audi parts. They will carry good quality aftermarket & genuine parts.
I am here after mechanic quoted me $750 for this job. After watching, I guess I have to pay it. All that for a thermostat. Yikes
Edit: does that quote sound right? The part itself is $40 from ecs. I think these guys are $180 an hour. You did it in 17 minutes. Should I look for a different mechanic? What would you charge? Thank you
This "part 1" video is 17 minutes... it's called editing. Part 2 is 26 minutes (edited).
I / we replace the whole thermostat assembly... not just the part inside, as this is a "sealed housing" / can not be separated. I don't deal with pricing... not all shops have the same hourly rate, currency, markup on parts (everyone marks up parts, grocery stores, furniture stores, shoe stores etc etc). Do what feels right for you / suits your needs. Make sure that the thermostat is the problem... could be a bad water pump.
Bring back the old style reliable stat in the early a4.
Something tells me it's only gonna get worse (future designs). =(
My mechanic did this and I noticed there's still a small leak took it back and he said it was fix and still leaking the wierd thing is it only leaks wen the car is cold like sitting for about 8th hours then I noticed the leak any recommendations thanks.
If you can see the exact location of the leak... take a picture of it when it does leak and show the picture to your mechanic. If the leak has to do with the work that was done... it should be covered under warranty. If the leak is from a different area (an area that was not touched during the initial repair) then you might have to pay to have this one resolved.

What is the sensor in the lower radiator hose?
Thank You
Coolant temperature sensor, so that the ECM can keep track of how warm the coolant is... that is coming out of the radiator. The ECM also uses that information to determine if the thermostat is working correctly.
Is this a possible reason for code P2181? engine cooling malfunction. My water pump is ok, so i think no overheating, and my temp sensor seems to work needle is smack in the center. However temp seems to take a bit in the morning, my guess its stuck open.
+DJWario Most likely a faulty thermostat: wiki.ross-tech.com/wiki/index.php/18613/P2181/008577
Yes, thank you it was :) a pain to replace but code is now gone.
+DJWario Thank you for the update!
Update: checked AudiTT 2.0L
55*F OAT > Operating temp 8 minutes. Is this about normal?
After 8 minutes, engine should be warmer.
I was going from engine start to ECT needle pointing at 12 o’clock. Average 55 mph. I guess I will attach OBDII test meter to check it. What should be the full warm up time from a cold start?
@@mikef6706 I might not have understood what you meant, sorry. Needle at 12 o'clock is 195F.... from cold start to 195 in 8 minutes is ok.
Good job dude!
Thanks for watching!
Why dont you replace the coolant flange while your at it? im doing mine and im having a hard time…
+Miguel Ernandes Sure, it can be replaced while replacing the thermostat... but if it's not warped, why replace it (that's what my customers always ask)?
Man.. It took me the better part of 5 hours to change the coolant flange Replace the coolant and pressure up the cooling system for leaks today including the a couple trips to Harbor Freight And Pepboys. I have a couple videos of the flange… It wasent easy but i saved 400 Bucks…
Miguel Ernandes I'll check out your videos when I get home.
is the quickest way to get it out.
***** What do you mean?
Meaning good job, was quick and easy. Thanks for the vid.
***** Ok, thank you. It took longer than the video shows... editing makes things look faster. :-)
Yeah I know, took about an hour and a half.
After seeing what I had to remove thanks to your vid. The oem procedure is a joke that would take almost twice the time.
WILL THIS MAKE THE CAR SHAKE WHEN YOU DRIVE IT AND THE CHECK ENGINE LIGHT COME ON.
No.
Faulty ignition coils will do that.
Hanz Rhubs Yes, I guess I should have mentioned that... thanks for letting him now!
That bottom hose is a bitch to get off. Do I just need to use more physical strength, or is there some trick like twisting it that needs to be done?
The lower rad hose with the plastic flange that clips to the thermostat? Once the clip is in the unlocked position (removing the clip completely can help) the fitting / hose should slide off. I sometimes hit / tap the hose flange with a long screwdriver or pry bar to knock it free.
@@EXOVCDS Yes, that hose, we used needlenosed pliers to get the clip off. So, do you mean hitting the hose at the connection from the top? Or try hitting it in the direction it comes off of (towards the right)?
@@peternichols9628 Hit the top of the plastic that is part of the lower radiator hose (the part that the clip was in). You can see me tap the hose flange in this video (similar thermostat design):
ruclips.net/video/JMhMyCTGZ64/видео.html
@@EXOVCDS Wow, after working on that stupid hose for about an hour, it came out in like 3 taps from a hammer and a metal pole 😂😂 We one you one man 👊
@@peternichols9628 Thanks for the update... good to hear you got it off!
OK I SCAN IT AND THE CODE WAS P2181 COOLING SYSTEM PERFORMANCE AND IS RUNNING COOL AND THE CAR WILL NOT GO OVER 45 MPH.
Might have more than one issue / problem.
