Great tutorial. Just replaced this part in my Golf GTI Mk6. Cost $38 for the coupling and an hour of my time. Saved me a couple hundred dollars, cheers mate!

[@DrewFixIt]

Awesome, these stories is what this channel is about! Thanks for sharing:) Cheers Drew

What a great video. I just had this happen to my A3 8P and noticed the coolant spilling out of the rear of the engine with white smoke everywhere. Turns out it was just this. Thanks for this detailed guide! This car has been a nightmare to own with all of the plastic parts in the engine bay.

[@DrewFixIt]

Thanks for the feedback and good luck with your repair! Yes, unfortunately way too many plastic parts in these cars… Cheers Drew

[@michaelmceachern-ru8bz]

thank you so much! had the issue on my VW cc and was able to fix it in roughly an hour. amazing! you saved me a trip to the mechanic!

[@DrewFixIt]

Hi Michael, so glad this was helpful and a genuine thanks for the feedback!! Cheers Drew

What was the part number I have a 2011 vw cc and I can’t find it

[@tedjohnson64]

Brilliant video! Just had this happen to a 2013 VW Beetle Turbo.

[@DrewFixIt]

Cool, hope you get it sorted easily! Cheers Drew

Doing my 02 sensor and I just snapped that nipple off. Thanks man.

[@DrewFixIt]

Bugger! Good luck with swapping the quick connect now! Cheers Drew

[@PRAYIMAKET]

Your a legend bro. i hope its as easy as what my vw mk5 golf that i was working on i had to take the rocket cover off just to get at the hoses it was a big job but nothing major.

[@DrewFixIt]

Thanks mate!! This one certainly ended up being easier than I expected when I started :) Cheers Drew

Good comment to Audi about saving 50 cents and letting you break down on the side of the road. Have a 2015 Passat TDI SE, and I keep thanking VW for saving their 50 cents with plastic heater hose parts, all the while leaving me broken down a number of times now. But to be honest, VW is brilliant; I'm not sure how on Earth they could make anything even more cheaply? It really does take a lot of engineering prowess to actually make something as cheap as they have. Kuddos VW!

[@DrewFixIt]

Hi Mate, I appreciate what you are saying however I would rather pay the extra 50cents and not have critical parts let me down!! Cheers Drew

[@jawsone]

Awesome bud, thanks

[@DrewFixIt]

No problem 👍 Cheers Drew

[@charleschetty1886]

Absolutely brilliant tutorial. Wasn't so smooth sailing for me though. Golf 6 GTI, 2011, dsg, replaced both heater connectors. I broke the breather hose trying to replace these couplers. The breather hose requires some pressing on the tab to release. Getting these couplers to fit requires some effort. I couldnt get them to fit on the heater core pipes. The trick that helped, put the couplers in hot water then fit them.

[@HananHussain-om5pf]

I’m having this same issue. You just ran it under hot water and it snapped on? When I go to put the coupler on it doesn’t go all the way in and the metal wire doesn’t click into place

[@KiridaKapileo-lg6ku]

Hello What is the 2nd hose called? That’s right underneath the one you replaced cause that’s the one that’s leaking for me

[@masonpugh3637]

This is great video thanks you mine cracked right at fire wall it was brass going on into fire wall

[@DrewFixIt]

Just a pity this fitting is not made of brass …. For a few extra dollars from the manufacturer then it would never break!! Cheers Drew

[@hugoroa6012]

Thank you very much for u help the help me appreciate 👍👍👍

[@DrewFixIt]

No problem 👍 Cheers Drew

[@Dislxud_kid]

was there an o ring on the other end of the heater matrix when removing the defect plastic connector?

[@DrewFixIt]

No. There is an o ring inside the quick connector. Cheers Drew

[@Dislxud_kid]

@@DrewFixIt spot on thank you! And for the quick response

[@DrewFixIt]

@@Dislxud_kid No problems. When you look inside the quick connector there is actually a rubber o ring and then a plastic tapered washer which fits absolutely perfectly inside the quick connector. The whole thing just pushes onto the barb. Cheers Drew

[@jacksonpaleaae7518]

Yea i did the opposite i took the hose off first before removing the connector which now im having a hard time taking the connector out 🤦

[@markkirksey2161]

Thank you for the video!

[@DrewFixIt]

Hi Mark, I'm glad it helped! Out of interest what specific type of car did you have this issue on? Cheers Drew

[@markkirksey2161]

@@DrewFixIt it was a 2012 audi a3.. thanks for the video it really made it easy for me to be able to fix it myself

[@ameermiakhil4447]

Where did you get that part from ? I've not been able to drive my car for over a week now because of this thing .

[@DrewFixIt]

Hi Ameer, this car is actually my wifes daily drive so I couldn't wait, so I literally drove (in my Merc) to the closest Audi Service Centre the morning after it broke (it broke on a Sunday) with defective part in hand and once they opened asked them ever so politely to sell me one that wasn't broken! Also, given the criticality of this part I wouldn't recommend actually buying non-OEM anyway. Cheers Drew

[@nomash1298]

Is top inlet heater hose? Thanks

[@DrewFixIt]

Hi Mate, they are both heater hose, one is the inlet the other is the outlet! Cheers Drew

[@talldave7799]

It's amazing how the Germans still continue to use plastic parts attached to Metal parts in heating system!! Mind boggling ! Our VW Gold is missing heat and I can't wait to find out what sort of plastic part has failed under the hood!

[@DrewFixIt]

Yep - good luck Dave! Cheers Drew

[@abigailabonza6057]

Was there a spring inside the hose with likena thermostate thing inside the spring

[@DrewFixIt]

Hi Abigail, no there is no spring inside the hose. There is just the clip to retain the fitting. Cheers Drew

[@sebsmith2173]

helpful thankyou

[@DrewFixIt]

Awesome, thanks for the feedback!! Cheers Drew

[@raymondzhao9557]

WTF they are using plastic parts

[@davidonofre1961]

Alguien lo encontró en español?

[@DrewFixIt]

Hi David, are you looking for a Spanish version? Cheers Drew

[@biz4twobiz463]

very nice video and explanation. Only one tip, but at the 7:00 minute mark, it's not necessary to open the quick connect before pushing onto the heater core. They are made to connect in the closed position. Just push on...and you hear a click. That's the positive connect. Merci

[@DrewFixIt]

Hi Merci, thanks for the tip! I really appreciate the community in the comments helping everyone out! Cheers Drew

[@KramerX69]

This man is a legend! Could see the coolant leading from my car but wasn't sure what all would have to be replaced. See this video of the exact same problem and only $20 later she's running great 🚗 the screw for getting the plastic bit out of the hose is great

[@DrewFixIt]

Hi Sam, thanks for the encouragement!! Cheers Drew

[@gregmeechan7874]

Thanks so much for this. Had the same issue on my wife’s A3 and this saved me hundreds of dollars and a lot of time!

[@DrewFixIt]

Hi Greg, thanks for sharing your feedback!! Cheers Drew

[@EpicBr0]

Thank you! Had this happen to the lower hose connector on my MK6 GTI 2011. The plastic barb snapped right off while i was driving and i stopped at a stop sign, and my engine is smoking!

[@DrewFixIt]

Hi Mate, hopefully it is just steam from the coolant spraying straight onto the hot exhaust!! Good luck 🤞 Cheers Drew

[@jrpefx]

Thank you for the excellent coverage on this repair. I will use this information on my 2012 New Beetle. Stay well.

[@DrewFixIt]

No problems! How did you go with your Beetle? Cheers Drew

[@DingusMcPants]

Thank you for this. I need to do this on my 2012 EOS and you've given me some confidence that I can do this myself.

You can do it! Cheers Drew

[@ahsanmiah7159]

I’m having problems taking the part off it’s stuck on , what should I do ?

[@DrewFixIt]

Hi Mate, it probably just needs a good tug! Cheers Drew

[@GAPRacing]

Can I block both off to be able to drive the car? Summer time here dont need the heater. If possible what is the patch fix until I can get the part? Thx

[@DrewFixIt]

Hi Mate, the issue that you have is that small barb to the small tube has deliberately been put in by the VW/Audi engineers to bleed the cooling system. So by bypassing the heater core as we used to do in the old days you simply then don't have the bleed mechanism to get rid of any air pockets in your cooling system and if you do have trapped air in the system your temperature gauge may not work. Note - I am told that some people temporarily screw in a screw into the hole where the small barb breaks off just to get home, but do this at your own risk! Cheers Drew

[@GAPRacing]

@@DrewFixIt Thank you kind Sir! Was able to get the part in the morning and had it installed in 10 mins. It took a lot longer to get the Intake piping back on. I must have rushed it cause I feel vibration in the clutch. So something is banging somewhere. LOL Awesome videos!

[@Hello-ce6nx]

Great video, Sir. I was wondering if you had any ideas of freeing up a seized quick disconnect just like the one you replaced. My wife's did exactly the same thing. I pulled the spring clamp, but my fitting is frozed solid after 17 years. I cannot tell, but are the heater core inlet and outlet plastic? I do not want to break the heater core. Thank you so much.

[@DrewFixIt]

Hi Mate, yes you have a dilemma here as you don't want to break the other plastic fitting. Suggest perhaps you could try temporarily putting a screw in the little hole where the barb has broken off, fill the radiator with coolant and then run the car up to temp. Once up to temp, shutdown the car and try to remove the fitting. *** Note - be careful you don't have a leak anywhere or that you don't have any big airlocks in the cooling system and be careful not overheat the engine! Cheers Drew

[@HannahsGarage]

Hi Drew thank you for making this video. Does the coolant need to be drained completely before performing this repair?

[@DrewFixIt]

Hi Joel, no the coolant does not need to be fully drained. You will probably have lost a lot of coolant though, so make sure you top it up with the correct specification coolant! Cheers Drew

[@HannahsGarage]

@@DrewFixIt Great, thank you for the info!
