Thermostat Replacement and Cooling System Upgrades

[@HumbleMechanic]

If the video helped out consider subscribing ~ kzbin.info One note on the video~ When placing the thermostat in the housing, I mention a "DOT". That "DOT" is a bleed vent. ;)

[@Blaylock1988]

When I did mine I didn't pay attention to that dot (didn't know I needed to). The car has been running fine for a few months, is it something I should be concerned about?

[@HumbleMechanic]

It’s probably fine. I’m guessing there are some situations where it may not flow properly. But I wouldn’t worry much about it

[@oatmeal9164]

HumbleMechanic I'm so happy your doing all these mk4 repairs/upgrades, definitely gunna be referring to these in a few months

[@signal7407]

Picked up some of those Blue Point locking hose clamp pliers on your recommendation from another vid. Those things Rock! Thanks for all the great vids, keep it up.

[@dylanpowell3213]

What about if you replaced the thermostat, water pump, and upper/lower radiator hoses and the car still overheats, I don’t have temp #’s but about 3/4 up the gauge, only going uphills though

[@manihamedi2357]

Just did this on my golf 4 v6 4motion and it's the exact same as the R32. Followed this guide and it made everything so easy. Thanks for the videos Charles! Keep'em coming!!

[@therealderjett]

I really like that you gave an explanation for why you were doing the repair. Showing the fault code message makes this really clear for people who are new to the VW DIY community. Your camera work and editing makes this look easy. Another great video.

[@HumbleMechanic]

Thanks so much. Glad the codes help. The job is really not that bad. Like all VWs holding your tool the right was is the difference between an easy job and a bad day

[@89yanii]

As someone with an aging 04 R32, your videos are an amazing guide. Thank you so much!

[@HumbleMechanic]

AWESOME!

[@dmytrowp]

Yes!! Great video, had the same P2181 code. Replaced the thermostat because it was stuck open. Also replaced the OEM housing, green top, coolant cover, and the crack pipe. Upgraded the crack pipe with a 42DD crack pipe and managed to do so WITHOUT removing the manifold. It was a PITA, but it was doable. Had to do this twice since the o-ring on the pipe didn't seat properly the first time but I think it was still worth it rather than removing the whole manifold.

[@HumbleMechanic]

Man I hate the leaks after repair. The 42dd pipe is what the GTI HAS. :)

[@BlueBox777]

This is the most complicated thermostat change I've seen (that I recall). Good job Charles!

[@HumbleMechanic]

The 2.5 is worse. Lol. The W8 is electronic and under the intake in the “V”. 🤷‍♂️

[@qwiklok]

Excellent. Learned a lot. Although I have a V6 and 2 W8 cars, the principles are the same. I now know why I had overheating issues, did not bleed the air properly, plugged rad and needed a flush. Man, I made so many mistakes. . . . . as said, excellent. And a few tricks like dielectric grease, hose clip pliers, a clip pick, removing hoses etc And btw, you have a great voice for narration. Audio is crystal clear, huge difference.

[@holidayhouse03]

Wow....a torque wrench in action. I'd heard about such things but never thought I'd see one on KZbin.

[@HumbleMechanic]

Haha I’m not a torque wrench nazi by any means. But I try to include it when I can. That said I can get 10nm pretty close most of the time. 😂

[@siamean1]

I torque everything down to 1 ungadunga.

[@David_Watts]

@@siamean1 Of course we all know the Honorable Charles H. Hungadunga, lawyer for Groucho Marx, set the standard..kzbin.info/www/bejne/lWOvoqCZn66Yg7c

[@gplusgplus2286]

Actually I think they're ONLY used in youtube.

[@gtr-heavenparts3525]

I just replaced my mk7 thermostat and water pump and it called for 11nm and I also used a torque wrench, I ain’t messing about plastic parts and torque values.

[@chrisjones444]

My assumption is it’s the same steps for the 2.8 Trying my hand at this, this coming weekend. Aluminum thermostat housing, billet crack pipe 70c thermostat! Excited.

[@mcawrse]

Nice work Charles. I just did the t-stat housing on my wifes 04 Touareg VR6. :-) Those aluminum parts look great. The first time I did the job I used an aftermarket plastic housing. That was a mistake, it leaked like a sieve. Lesson learned and now it has a genuine part and no problems. The parts house took the junk part back for a full refund.

[@HumbleMechanic]

Glad they gave you the money back. Some of that aftermarket plastic is awful

[@Toolaholic7]

See it with the GMs,Chryslers and Fords with the PO128 code too.Replacing the thermostat fixes the problem too when this code appears.The hose picks,Snap On makes the best ones now.A wide flat tip instead of a pointy tip to prevent poking holes in hoses.

[@suj1945]

You have some of the best camera angles I've seen for demonstrating car work.

[@HumbleMechanic]

Thank you. 💙

[@TheMatadrum]

This is the best video ever - Just wish it was around 2 years ago when I was fixing this issue on my V5 Bora. Oh well...

[@RoguePlank]

Of course you've already done a video for this, thank you! My metal coolant housing and crack pipe are on the way, mine lost 2 litres of coolant over the weekend, housing leak against the block.

[@cmcolfax1]

Timing is everything... I'm about to do this job on my 2.0. I don't have to worry about the crack pipe, and things are a little easier to reach, but still a great how to!

[@HumbleMechanic]

Thanks. Be sure you replace the housing too. 100% chance it will leak if reused

[@cmcolfax1]

Yup. Got a nice box 'o parts from #autohausaz sitting here. Thermostat, housing with o-ring seal, outlet flange with o-ring seal, expansion/recovery reservoir with cap and seal and finally a new coolant temperature sensor...

[@1990lillulu]

You always make the jobs easier and explain everything necessary. Thank you again, and my car thanks you too!

[@HumbleMechanic]

Happy to help :)

[@tullgutten]

I recommend everyone to get a vacuum filling tool for the coolant, it creates a 0.8 bar vacuum so there is no air left, cost around 50 dollar (Here in Norway at least) and is worth its weight in gold. I use it on every car at work, and it doubles as a leak detector when you cant get vacuum because a leak. Takes around 3 minutes to bleed with it and 0.1% chance of overheating or having to refill more than 0.2 liter after driving instead of filling and having to rev the engine and drive until it is hot and refill again that might take over 30 minutes on some cars or even having to wait to it is cold again.

[@ferfire9]

I think its worth mainly if you work on many cars. But if you care about your money and only have 1 /2 cars at home, its just not needed, at least with VW cars. My car bleeds itself without much trouble pretty fast, 2 or 3 runs and the air is all out.

[@tullgutten]

i have 3 Audi XD and my dad has one, i think even for a home mechanic it is gold, saves much time and you can loan it to friends if they need it. at work we have 2 but I had felt the need for having my own as well, as I prefer to be 99% sure the engine wont overheat from a lack of coolant since that happened to me once before I bought the tool

[@glahut93]

I used the airlift brand but still can't get all air out .Now my bottom coolant hose is cold and car runs hot It has new fans,new water pump,new thermostat and new radiator.

[@panzerveps]

Gotta love the VAG vacuum bleeding kit.. One of the few special tools that makes the job so much easier.

[@HumbleMechanic]

Totally agree

[@rsage_]

I'm all about using a little dielectric grease on those hose connections and o-rings. Love that stuff. I use it for all sorts of other stuff, too; like at the bottom of the battery terminals (between the post and the cable). It definitely keeps the crusties away, haha.

[@HumbleMechanic]

Yea man. I use it all the dam time. Lol

[@mentaldan666]

This calls for a 12 minute toilet break! Screw work. HM comes first 😁😂

[@HumbleMechanic]

Comment of the year!!!!!

[@mentaldan666]

HumbleMechanic Lol! This R32 is an absolute beast, and already looks wayyy better than when you got it. Sounds incredible too. Between this and the VR, I’m practically nursing a semi 😳😂

[@HumbleMechanic]

Well you did just spend 12 min in the bathroom. Hahahaha. Just wait until you guys see the suspension. It’s 😎😎😎

[@yafte95]

Thanks man, this video was super helpful! Extremely clear demonstration on this rare engine! God bless you. Worked for Mk4 VR5 4motion

[@bassistproducerpitbullgymc6734]

Man… you are the friggin best at making these diy vids make sense !! I’ve done all of my repair and maintenance work on my Tiguan with your help!! Would there happen to be a vid of yours for the Tiguan ( water pump / ect / thermostat replacement instructions)??? Looking like it’s gonna be my next project as I’m noticing the slow start up and slightly overheating when idle…

[@rosesbite]

Thank you. I feel like I’ll be having to do this soon. Owner of a 11’ MK6 TDI. Brought my car to a mechanic to replace my timing belt. They did a flush and didn’t put the recommended G12 or G13 I’m my car. Instead they put the green coolant in my car. 5 months later coolant dash notification goes off because of low coolant -_- which either means I now have a leak or the coolant is simply evaporating in my cooling system.

[@RoguePlank]

Thank you so much for showing where the little hole goes in the thermostat

[@mattleggett9782]

Top draw video with ALL the info need to confidently replace my R32 thermo complete kit. Many thanks, great work.

[@MrWoowootila]

I would recommend getting the Ross Tech Vag Com. When I needed to program 2 keys it was cheaper buying the keys and FOB's online, cut, and program myself with the Vag Com, than going to the dealer and buying and programing there. Then I had the software to reset and trouble shoot codes on my car. It payed for itself in one use.

[@HumbleMechanic]

VCDS is awesome.

[@mikewiremt]

Something about pouring in some nice fresh G12 feels soooo good! Love seeing that color in the reservoir instead of green or brown.

[@HumbleMechanic]

:)

[@Sooperdooper74]

Awesome! I stopped everything to check out the majic. Yes the V-dubs, can be a bit hectic with hoses and wires. Great Job!, and thanks!

[@HumbleMechanic]

💙💙💙💙💙💙

[@selflesswanderer]

I get to do this today. Have watched the video several times, not looking forward to the crackpipe at all.

[@Motorsportsgeek]

Man these VW designs and materials they chose makes me cringe and make my mercedes look like a toyota in comparison...No offence, great video and right to the point , upgrading what VW cheaped out on was a great idea and investment!

[@HumbleMechanic]

LOL, I don't take offense to that. I didn't make that stuff. HAHAHAHA ;)

[@chrishernandez2490]

ltwargssf R, What I love about your comment is that to a non-car guy, it would make absolutely zero sense. "That VW makes my Mercedes look like a Toyota" "What does that mean?? Is that a bad or a good thing??" But to any car enthusiast they know exactly what youre talking about. XD

[@rohankhosla-stevens6068]

Does the crack pipe just tight-fit into the thermostat housing?

[@luisc853]

Thanks for this video Charles. It really helped me fix that DTC on my mk1 TT 3.2!

[@jellevanonna1389]

Absolutly love this type of videos. Super clear and every question u might have is answered. I am about to replace my themostat on my mk4 2.8. This will help alot!❤

[@HumbleMechanic]

Awesome thank you!!! Super pumped to help

[@stonewp]

Really enjoying these R32 videos. I have an mk1 TT with the 3.2 VR6 so a lot of these videos apply to my own vehicle. I’ve had to have the thermostat housing, temp sensor and o-rings a few times. My primary cooling fan just retired so I’ll be back in that area again soon. Do you have a recommendation for a silicone coolant hose kit to refresh all of the old rubber? Is there a reason that you painted the aluminum parts? Glad you picked up the R32. Keep up the good work.

[@marcgonzo8783]

You made that look way too easy.. I needed to put my R32 in service mode to get the "crack" pipe out. It did not want to just pull out. I also noticed in the video you have secondary air pump fault codes as well.. How are you going to trouble shoot those? I have them as well. I have been knocking my head trying to figure out what is wrong with it. Hope you do a video on it!

[@HumbleMechanic]

Pulling the front is a good way too. I actually think the secondary air faults may be related to the HFC. but I haven’t really dug into it.

[@marcgonzo8783]

HumbleMechanic I hope you make a video on it! Would help me out as well.

[@leoreyes8261]

Same here same code for me

[@braddowns17]

Great video as always. You always think of putting in the thermostat in the correct flow position but leave it to VW to have to clock the thermostat as well. Is it that way with all VW water-cooled engines or just a few?

[@HumbleMechanic]

I think the Vr is the only one that is oriented. I THINK! Lol

[@braddowns17]

HumbleMechanic Thank you I have a 12 valve VR 6 in my Eurovan based Rialta and plan on changing the pipe and thermostat when decent weather hits. Good thing to know. Thanks again.

[@naomithemarketer]

Awesome channel! I Just bought a 2003 VW Jetta and when the car is in idle it overheats would upgrading the coolant system solve my problem any advice?

[@carlosmartinez-kl1ho]

👍👍👍👍 this video is going to come in handy this weekend

[@christophertenley6654]

Great video, love watching you work on your vw, I was curious, as to the coating you put on the housing and crack pipe before installing, what is it and did you do it yourself

[@milosilic1456]

Great video Charles, love your work. Can i do coolant replacment and bleading procedure without that no spill funnel.❤

[@Badgertronix]

Milos Ilic it has a header tank, you don't need a spill free funnel

[@HumbleMechanic]

Yep. No need for the funnel. I had it and wanted to try it out.

[@milosilic1456]

HumbleMechanic, thank you man you are the best.

[@993ts]

The piece you mentioned might brake in the beginning of the video broke on me once. I just bumped it while doing something not related to the cooling system and the next thing I know I was getting hot coolant sprayed on my face. Fun times.

[@HumbleMechanic]

Yep. Seen dudes get some nasty burns from that part

[@rubenlarosa959]

[@oxulucozcan4923]

Hello humble mechanic, newbie to your channel here, One question though, wouldn't silicone paste be a more appropriate lubricant? Isn't dialectic grease an electric insulator? Thanks in advance and have a nice day

[@xziang]

New to vw world, but guessing their radiator designs don't have a radiator cap like you would find on GM/ford? Saw on the refill of fluids you used the overfill tank instead of radiator.

[@fuenteskevin72]

Car genius, i can only hope to have half the knowledge you do.

[@DavidMortaz]

Wil I be able to tell if my 2013 Golf TDI thermostat is bad by reading the Temp on the Sensor? What should the temp reading supposed to be? It's taking about 15 minutes for the Temp Gauge to reach the middle and there is no HEAT coming inside!

What's the story w/ upgraded crack pipe and housing regarding fitment problems causing leaks. I have yet to replace mine on 2003 VR6 w/ 90K on it. Appreciate any feed back!

[@Scouty208]

Is there any practical purpose for putting on the coating on the new parts or is it just for style?

[@daRayofSunshine]

Great video!! I wonder if it's would be the same as mk5 r32?

[@HumbleMechanic]

Very similar

[@beerweather1566]

How important is cocking the thermostat in the housing the same direction? It’s not upside down. I just did this yesterday but I didn’t add coolant yet

[@ExhaustedOfficial]

Great video, concise and informative. Good job👌🏻👍🏻

[@full_metal2452]

Is it possible to swap out the coolant temperature sensor without pulling housing out of car or taking front end off and moving support forward on the mk4 2.8 vr6?

[@dustgr]

Just a quick question I have a golf 4 with the plastic thermostat housing and thermostat , if I ll change it with the aluminium housing + metal thermostat.

[@bernardaflores1720]

I read some forums where they install a metal crack pipe only to have it leaking or not sealing properly. Is the one in your link the better one??

[@HumbleMechanic]

That I’m not sure of. I’ve installed a bunch and never had one leak. Often times issues like that are an error by the installer

[@Mellchior]

Another P2181 checking in! Mine is on a MKV GTI. Nothing like lukewarm heat all winter :D

[@dyelan2010]

I always have leaks from the where the housing hooks up to the head ANNNNDDD where the sensors hook into the housing. I've been careful, and I still get leaks the first time. Second time with some sealer usually works but makes a redo of the job messy.

[@stonewp]

Is there any concern with the little bit of dielectric grease used to lube the seals mixing with the coolant?

[@Shika906]

Hey Humble Mechanic, I stumbled across your channel when I bought my R32 at the beginning of this year which if i recall correctly is around the time you got yours. It has been really funny because our repairs have been close to identical with some occurring at different times. I just got the P2181 CEL and am going to be replacing the thermostat (already replaced the black CTS). I also, coincidentally, got the same P0113 Intake Air Temp sensor code as you. Have you found a solution to this? I have been told that the sensor is built into the MAF and I have done a visual inspection of the MAF wires but it "looks" ok. Would appreciate feedback on how I can rule out wiring vs the sensor before I drop a good chunk of cash on a new MAF. I appreciate your help and please keep up the good videos, they are helping a ton!

[@HumbleMechanic]

If you have VCDS you can see the temp in the scan tool. The wiggle the wires to see if it changes. Also if you had the key on with the MAF unplugged you’ll get that code

[@Shika906]

@@HumbleMechanic Brilliant, wish I had VCDS, maybe I can get my local mechanic to help me out with that. I do remember forgetting to plug the MAF in before starting it a few months ago. Turned her off, plugged in, and it went away. I have since disconnected the battery (between two separate scans when I got the CEL) and it either came back or did not erase. Hopefully the CEL is solely due to the thermostat and the other code is a remainder stored as history or something. Trying to decide if I want to go all aluminum housings/pipe or just replace the thermostat. They aren't a problem now but I bet they behave like the mk4 gti flanges (leak leak leak). I'm more in need of brakes/rotors and am looking at doing a big brake upgrade. Watching the thermostat replacement for this car it's hard to say no though since I'll be there with everything off.... wish I had the money, then it wouldn't be a question! Thanks for the help and being an awesome contributer to the dub world!

[@vanterg3]

I got 2000 vr6 Jetta and Idk where the coolant is going it’s not leaking or anything it’s just going somewhere else in the car and I got thermostat change last month

[@AP9311]

Charles, I may be way off base, I mentioned on IG that you're spending about 15k on R32. But spending more money to get all the issues fixed. I would think you might be getting the R32 at cheaper price with the issues on it? Correct me if I'm wrong! :) just wanted to hear your opinion :) Ty for the awesome videos you put out! They're great source!

[@HumbleMechanic]

I bought the car for ~$11k. I assumed that with 140k the car would have all teh common MK4 issues. There have been a few that I didn't expect and I am okay with that. The cool thing about the amount I paid for the car is that it doesn't matter one bit. It mattered the day I got it and it will never matter again. Now I am focusing on getting the car right, and making awesome content for you guys.

[@AP9311]

HumbleMechanic awesome! Thanks for your reply, now I understand :) I look forward to see many more awesome content, Charles :) I don't usually work on VW's, but I learned a thing or two about doing it from your videos. They're rich source for knowledge! Way to go, my friend!

[@alexmessina3383]

Hello charles, thanks for great vids!! Some advice please. I've just replaced coolant thermostat with housing on 2002 Mk4 Golf. It has the green coolant sensor and also an extra 2-wire component that connect directly to the thermostat in the housing. Trying to understand what the extra component does. cant find a PID for it. Believe it may allow PCM to trigger trigger opening at lower temperatures, or perhaps it is just a on/off signal to PCM to indicate when thermo starts to open??? Keen to understand its function and how it works.

[@jeffalsop5299]

Great stuff! Thank you for showing!

[@dylanmckinney3405]

Great video as always. Why the dye electric grease tho? I know it creates a seal to help keep dirt and water out of as well as lubricates the plug on electrical components. Is it acting in the same manner for this application? Also, would the grease getting into the cooling system be any cause for concern or no because of the small amount? Thanks in advance

[@HumbleMechanic]

You nailed it. Purely a lubricant for the seals. I’ve been using it forever. Never seen any ill effect from it. I guess if you put a crap ton on it may. Haha

IRL this is a hell of a job for vr5 motor, well at least for me it was. Had to take the radiator off, to access it, did everything as repair manual said put it all together (4+ hours of work as diy'er) aaaaand there's a leak. This happened 3 times, wasted my whole weekend on this. Turns out it was a poo quality seal which connects to the block, ended up with placing original seal added with a high temp hermetic and prayers along with my wife questioning my manhood. After a week it developed a leak in the same area, i just said dang it I'm not going to do this again and put a radiator sealant in the antifreeze (yes I am a son of a female dog to trust it) but it worked, 20k+ miles and still not a problem.

I have a question as I'm running around trying to figure out a problem and am out of ideas... I just performed a coolant flush for my wifes Audi Q3 (2016 Quattro) and now I'm running into an issue where the radiator is not sucking the coolant out of the Coolant Overflow tank (this was also replaced for a brand new unit, btw). I definitely have coolant flowing into the heater core (as I'm getting really hot air) but the lower radiator hose is simply not flowing anything. We definitely utilized a vaccum bleeder/filler to load up the new coolant (even drained it again and performed a refill) but we just can't seem to get it to flow through the radiator. Any ideas would be helpful

I have a Audi TT mk2 with vr6 engine And I have to replace thermostat Is this the same procedure?

[@soranrix]

since this is an upgrade will you put the dsg intake on the car??? it will need a reflash but gains are good and still oem, the lmm is 10mm bigger on the dsg version(same as the audi a3 3.2 250bhp) it´s officiel 9bhp since the r32 only has 241bhp. regards Sören

What do you do with the coolant that sprayed onto the transmission

[@HumbleMechanic]

Wipe it down or rinse it

[@JimGriffOne]

You should really try one of those snake radiator clip tools. They're so easy to put into tight holes. [That's what she said joke]. But seriously, they're so easy to use you'll probably never go back to normal clip removal tools.

[@HumbleMechanic]

I have one. I never cared for it. I think it’s because it was a cheap one. The only time I ever used it was mk4 PD egr cooler recalls.

Hey Charles. Can you do an in depth video on how to remove and reinstall the belly pan/undertray? I understand their is more than one and some are missing on my R32. Cheers. oh also should the radiator fans on the Mk4 R32 come on at the same time? My small fan always runs (probably because I have the aircon on) but the big fan doesn't seem to come on that often.

[@HumbleMechanic]

Oh man I JUST installed the DieselGeek pan so I’m missing most of mine too. Lol

[@mitch9894]

Interesting do people remove them? or do the get "removed by nature" if you know what I mean.

[@HumbleMechanic]

Both. Mostly I’d think from people hitting crap
