Gracias por tu video.

[@Ivan218374]

Спасибо за столь подробное и чёткое видео.

[@dwayneearle8787]

Great video! I especially like the recommendation to cut the old core pipes. I didn't, used a screwdriver, and the firewall pipes flanges bent them so they would not seal. A 1-day easy job turned out to be a 3-day headache. One recommendation is, Blow compressed air through the firewall pipes in the engine compartment. There will be a lot less coolant to spill.

[@Servicetutorials]

Thank you for the tip, Dwayne! 👍

[@Servicetutorials]

[@michelwathelet3354]

Thanks a lot

[@radulepg]

Perfect explained!!! Is it possible that the radiator broke and there is no water in the cabin, but that it flows under the chassis outside? I'm asking because I can't find where my coolant is leaking, and I see drops under the car. The mechanic looked at all the forks and they are all dry, and we can't see where the fluid is coming from. I didn't open inside the cabin to check this radiator, so I better consult with you. I didn't notice that my windows fog up, maybe a little in winter, when it's humid outside. Passat b6 2008 2.0 TDI PD engine. Thanks in advance!

[@mattspry8576]

Do you not need to drain the coolant before disconnecting the heater hoses? I only see you mention taking the cap off to release pressure

[@Servicetutorials]

Yes, you can drain the coolant if you have any, in our case it was drained all over the carpet inside.

[@redouan1234]

👍

[@colinchandler6516]

got a question will this method work on my 2004 vw passat glx v6 2.8 sedan?

[@Servicetutorials]

No, you have a different Passat, the older generation. It’s different.

[@colinchandler6516]

@@Servicetutorials I'm a try it cause it looks the same under the dash

[@dafinfeel7942]

Hello, do all these steps work for the Polo 9N as well?

[@Servicetutorials]

Hello! I don’t know if it’s the same procedure. Sorry!

[@abdelmalekhamadou2280]

Is it the same for crossfox 2007 thanx

[@Servicetutorials]

I don’t know, I did not remove it from that car model.

[@philipgordon8262]

Same thing for the mk7 golfs?

[@Servicetutorials]

Yes, it’s similar.

[@kennySC0313]

Why remove the screw? What does that give you?

[@jaksel]

If you mean the screw in the engine compartment, I think the reason is that you need to be able to pull the pipes back in order to detach the heater core.

[@ninjam6808]

Is it the same for the scirocco?

[@Servicetutorials]

I don't know, sorry!

[@jonz25]

Is this the same for Passat B8?

[@Servicetutorials]

I don’t know, sorry!

[@tiddybearkush]

Don't use petroleum based grease on rubber gaskets or orings.

[@Servicetutorials]

Thank you for the info!

[@randalantunes2681]

Great video However I don’t understand why you left out one of the worse part the process which is to disconnect the pipes. It’s a very poor design by VW. Among many

[@Servicetutorials]

Thank you for the feedback!

[@andy_muscle]

Thanks, can anyone explain what's the purpose of removing the screw? 14:19

[@Rickydiamondxk]

Someone needs to pull from the outside so the pipes separate
