Thermostat replacement on a VW PASSAT B7 saloon - problem-solving [TUTORIAL AUTODOC]

[@ranno3132]

Thanks to this video I managed to change the thermostat on my 2014 Skoda Superb. Thank you! Terrible work. I allmost gave up many times. I recommend using a hose clamp tool with a cable(on one end of the cable is a hose clamp press and on the other a grip to open and close the hose clamp press). Makes it much easier to access all those hard to reach hose clamps. I could not have done it without this. tool.

I did it today... spent hours to unmout everything, get out the thermostat for the egine compartment, etc... mounting everything again and while putting liquid colling in the bowl I got leakage under the car :(. I guess the gasket/seal of the thermostat did not get the good place. Need to to it again from scratch what a nightmare. 6hours lost

Extremely well presented, that couldn't have been an easy one to shoot!

[@autodocuk]

Thank you for sharing your opinion!

Is it same process for CFGB 2.0tdi engine ?

[@the2120company]

thanks for video today some automakers make it very difficult . but there is still some easy ones

[@craigwhitlam9230]

Thanks for this video wouldn't have attempted it otherwise. With a cable operated hose clip tool getting the hoses off wasn't too bad. Hardest part of the whole job is getting that bottom bolt off/on the thermostat to the block. Worth noting they are using a 10mm 'wobble' socket with a 1/4" drive to get access as it's super close to the alternator. I ended up using a short spline bit (8) and a 10mm spanner instead to crack the bolt off. Also the bolts on the EGR valve are T30 not T27. Defo have a magnet to hand as you will drop bolts!

Thank you very much for your feedback. We are glad that our video was useful to you.

Well explained and done 👏

Super helpful. This gives me courage to perform the maintenance myself. Will update once done.

[@smikey5304]

What happened to simple functionality? It's like engineers set a goal to build a car that requires you to remove the dashboard just to add air to the tires.

[@samrowland2816]

It's more to make at as quick to assemble at the factory as possible and mechanics be damned

[@ManufacturedCrises]

@Jazzmaster Jay Volkswagens do!

[@christownsend7602]

I have a 1985 Ford 460 V8, and it takes about 15 minutes, and most of that is draining the coolant. It takes one socket and a screwdriver. This is crazy just for a thermostat.

[@인내-t8c]

좋은 정보 감사합니다~^^

[@melvillehollamby5816]

Great video, My Jetta looks pretty similar except I have a EGR valve and my oil filter is right in front of the bolt of that last hose on thermostat. I also couldn’t get the bottom bolt on the thermostat and had to remove my alternator.

[@liamashford7358]

Same as my scirocco mate, managed to get at that lower thermostat bolt with a shallow 10 on a wobbly and about 10 extension bars, absolute nightmare of a job

[@ryanbarrimore9703]

Good video. Is this the same for the 1.6cayc engine at all. Looks very similar under the bonnet. Thanks

[@sardo1]

Shouldn't you change the O ring on the plastic pipe that fits into the back side of the thermostat?

[@autodocuk]

This depends on many repair factors. We cannot show all the nuances and problems during replacement; this is all individual. To avoid this, we always recommend that replacements be carried out by specialized car services.

[@odeyon1]

Took me almost 5 hours. The bigest problem was undoing the bottom screw. I have quite. Good selection of tools but couldnt get anything on it. Ended up making a tool from an M12 cap head bolt. Once loose I was able to undo it with a 6mm ballended alen key. Deolacing the bolt was tedious as it was not posible to push the housing home. Had to wind it in with the screws, Very slow going with resistance against them.

Autodoc la mulți ani , video cât se poate de multe , Felicitări ! ❤😘🙏❤😘🙏❤😘🙏❤😘🙏

[@Ltencio]

He visto varios videos iguales para hacer este procedimiento, me pregunto si por quitar el cuerpo de aceleración no da ningún problema de programación ?

[@autodocuk]

In some cases, when removing the throttle valve, using a diagnostic scanner, it is necessary to carry out an adaptation program, but in this case, it was not necessary to do this. AUTODOC

[@johnh3194]

How long a job is it to replace it time wise. Just mine is stuck open.

[@autodocuk]

You can find this information in the technical documentation for car repair.

[@borutgoli840]

you are great. just loose music and add instructions what you doing.

[@trickyfocus]

yeah i like to hear just the sounds of the ratchets etc hate music

[@david202c]

i have a 2014 passat tdi nms are there any gaskets you should have on hand and is it okay to use the auto fill coolant tool that removes air and sucks the coolant in?

[@autodocuk]

It is not possible to unequivocally answer your question, you can find this information in the technical documentation for the repair of your car.

[@user-bw7bj2ji1u]

Why did you remove the bolt xzn socket bit 6?

[@autodocuk]

We removed it according to the replacement procedure following the manufacturer's recommendations. AUTODOC

[@steeleyg225]

Was thinking the same

[@TallDudeSSj]

I was wondering the same, as the bolt is "way over there" from everything else 😅 what is it holding in place? 🤗

[@neilgalloway2328]

this is a fixing for the pipe that runs left to right from the thermostat, without undoing the bolt that pipe stops the thermostat coming straight out

[@JamesNew-bk3qe]

Will this be the same process with the Passat b8?

[@autodocuk]

We cannot tell you for sure. You can find this information in the technical documentation for repairing your car.

[@СергейРуденко-и6о]

Замена термостата помогла двигателю прогреваться хорошо до рабочей температуры?

[@autodocuk]

Yes, in this case, the replacing of the thermostat helped the engine to warm up to operating temperature.

[@amastershock]

Can someone please tell me what is the "all-purpose cleaner spray" I been looking for it for ages but nothing that I could find on the net. Is it brake cleaning spray. Thanks

[@amastershock]

Thanks

[@172steve]

Not an easy job this, couple of points though...throttle body bolts are T30, not T27 and the spline bolts are #8, not #6. At leat that was the case on my B7 Passat CAYC engine. If you can, change the hose clamp clips to jubilee clips as it'll be easier next time.

[@baronvondirtbike7814]

This job was a fu... nightmare. The gasket on the new thermostat broke, so I had to put the old thermostat back. I gonna buy a new gasket and next time I will apply som grease.

[@thibod12]

which gasket are you taking about ? I have to replace my thermostat this weekend and want to avoid any mistake...I guess put some silicone grease everywhere should help inerting all hoses right ? thanks

[@thibod12]

fuck ! I guess I got the same issue today.... :( I put back every on ..after spendy hours to unmount stuff and before shwitch on the car while putting liquid cooling in the bowl I got leakage under the car... I need to do it again from scratch argggg 6hours lost

[@baronvondirtbike7814]

@@thibod12 You need to apply some grease on the gasket/o-ring on the new thermostat and not try to fit it with a dry o-ring. But I guess you know that now 🙂

[@thibod12]

@@baronvondirtbike7814Thanks for your advice. I finally managed to it few weeks ago. I finally remove the oil gauge + another hose to get more space to work. And no leak this time... and the most important thing, now water temperature remains stuck on 90°C ! no oscillation anymore good :)

[@andersb8408]

Did ju raise the car just to drain the coolant? Or is it a procedure required to charge the thermostat?

[@autodocuk]

Thank you for your comment. Yes, in this case, we only raised the car to drain the coolant. You can find the correct replacement procedure in the service documentation for servicing your car. AUTODOC

[@judylambert6156]

How long does this take

[@TheCatoLee]

About two years. You have to disassemble the whole engine first. And there is a million «while you’re in there» as well

[@andriesoneill5038]

this looks the same as the VW Touran 2l tdi 2013. am i right?

[@autodocuk]

The replacement procedure may differ, you can familiarize yourself with all routine replacements directly in the technical documentation for your car or use the help of the auto maintenance service. Happy New Year! AUTODOC

Wery good video, except for that innoying music

[@trickyfocus]

Lose the music please just the sounds of ratchets etc

[@davidsolera5883]

👌👏👏👏👏👏

[@cmecu_seemeseeyou9330]

Hate new cars and foreign cars. Working on your own vehicle was so much easier back in the day, with LOTS of room around the engine, no special tools needed. Plenty of room for tools, and no need for 100 different kinds of wrenches and screw drivers... crazy why engineers woudl want to make things more complex.

[@ericoppel5698]

Your videos would be quite good if you eliminated the annoying and unnecessary music, and instead gave an intelligent commentary of exactly what you are doing and why.

[@autodocuk]

We will work on the quality of our videos. AUTODOC

[@richardwillson101]

I fully agree with you there! Less music, but a verbal commentary. That way, not only do people know what they are removing for this job, but they learn their way around various engine components. Always useful in future.

This has just put me off.
