Awesome video thank you man. This vid had the best lighting and camera work for this job that I've seen. Very helpful

I think I have my answer with this video. My first car I have is a vw 02 Jetta sedan and I been driving it for 4 months it has a coolent leak now I know I would tell my mechanic to check that out. Thanks very helpfully videos!! 😊😊❤

Cheers Cole, great video! I broke the thermostat housing yesterday when replacing the ignition coil of a Skoda Octavia of the same generation so I'll have to replace that. Always good to someone else do it first, very helpful man!

I believe this task is is in my future so just wanted to say great job on providing lots of detail from start to finish.

I really appreciate you for making this video. It is exactly the problem that I am having with my 2004 New Beetle, 2.0 engine. It took a while to figure out where the radiator fluid was coming out. The smell was easily detectable well in advance of finding the location of the leak. The housing split along a seam in the casting. I imagine the extremely cold weather we had last year was at least partially responsible for the crack. I don't believe I had the correct blend of antifreeze in the system even though the car had been worked on by a reputable foreign car repair company. Cheers. Just the advice I needed.

That fixed my really bad coolant leak! Thanks for the video and that saves me loads of money from taking it to the garage and i thought it was the head gasket!

Really useful video! I have an 03 Jetta which had the same problem, and I was putting it off for way too long. The coolant temp sensor housing on my car was brittle and actually broke when I was pulling off the large hose! Everything's back together now, and I'm really glad I finally did it. Thanks, man!

Great video! Thanks a ton my guy.

Informative and humorously entertaining.. subscribed .

Best video yet

@6:07 Nasty! Nice work man

Great video!

great video thanks a lot!

Great video, thanks 🙏

Hey you got to work with what you have 👏👏👏👏👏👏👏🙏thanks

Thank for this video

Vice grips will make your life easier with the clamps they will pench down and hold the clamps open. just thought you should know and you have me very valuable information and I thank you

Currently chasing a leak in my mk4 golf, totally getting the aluminum parts now, aaaand the tools 🤣 great video, thanks for making it. 👍

What type of flange was that you removed the very first one that's bent and has a small connector on the end mine's broke

You had me at "11year old schoolgirl"...

I bought the alloy coolant flanges that this guys is putting on and kept having leaks so I've put new plastic ones on and not leaked once

I have an 02 jetta that's been giving me grief, pretty much identical everything around the flange, but the metal pipe that goes over the second stud won't lift out of the way, it's securely held in place. Any insight on how I can move it?

Nice video, what's the like for the thermostat housing. Thanks

i’m 3 years late but what should i do if my new gasket for the aluminum part ripped in half while i was putting the new part on? do they make those separately? if so where do i get it from

Question - The small hose clamped on the thin tube at the upper most part of parts worked on. What does it do and what is it connected to at its other end (hidden)? I suspect it's an overflow of some kind. Thanks.

what is that thing you took that hose from and is connected to the airbox ?

I’m trying to remove the bolt that holds the metal line and the part of the flange that mounts to the engine block. The bolt is already about 85% out, but after about 3 rotations the bolt clicks and recesses those 3 rotations. Any ideas how to get it out the rest of the way?

Why can't I find a whole flange kit for a 2.0? Are 1.8s the same?

Hey what part of the country do you live? Have you been working on Vws along time. Love your channel. Your funny. I already replaced my thermostat, waTer pump, cool fans and ac hoses. Haha I hope they did the sensor when they put fan in but I doubt it. I guess I get to do that now myself. Because I can't trust anyone around here to even put the manifold back on right. My car is still leaking coolant. I been refilling it every two weeks and start sweating if I am getting anything out trunk with car on. It feels so hot by exhaust. I guess I'll try the flange next. I love youtube. I understand my car now as good as some non mechanic men and keeps me from getting ripped off anywhere now. I have to put the stupid battery connections together tomorrow. My computer seems cray cray after battery got jumped. I pray it fixes some shit. Anyway I am waiting to see if I'm rich or with good credit by the time the electric vw bus comes out in USA. I love all the videos and pics of it. Especially the buzz. Of course I wish I could remodel the old vws but they cost alot to keep up and Renovate and not always reliable or emission friendly. Unfortunately the old ones they are cop magnets when your in Bumfuck nowhere but I would love one still. Even traveling the country in my Chevy venture was like I had arrest me on my plates. Which i thought it looked like a 2001 mom van. With the vhs feature i thought it screamed luxury and class. They didn't like it one bit though. I would probably still be in prison if the stupid thing didn't have so many tire issues and eat rack and pinions. Hopefully once I get my buzz I'll have better luck haha if I get it

I know I'm a year late but any guess's for the 05 mk4 2.slow that's leaking coolant I've replaced the housing sensor and thermostat I'm thinking warped block hopefully not but cheers if you say the same 😂

would a bad coolant temp sensor or even a bad thermostat cause no hot air to blow inside the car? or would it be more likely to be a bad heater core?

Hello!! Where’s is the thermostat located at?

What are the two sensors on the outlet I know the engine coolant temp sensor but don’t know the other onr

Was the original coolant orange or was it a watered down pink?? TIA

The plastic clamps on VWs are all going to break even if you use the right tool. Every time you disconnect and break something you have to come up with a new creative way to keep it in place because the plastic snap broke off the end. Always happens with VW.

Dude I'm fucking shocked that your buddy still has the pull rod on his oil dipstick. On every 1.8 and 2.0 Jetta or golf I've ever worked on that's the first freaking thing that breaks.
