While doing the vacuum with silence it was good to hear the birds singing in the background one of the best soundtracks at this time of year keep up the great content
I love thinking back to your early videos where Chris hated been on camera to now where he’s like we have to get this on film, got his own instagram account Etc. Rob you’ve created social media monster 😂😜
Love Rob's response when Chris asked what the coolant capacity was......Rob......thinks for a moment with a thoughful expression and then gives a very informed sounding reponse....in a nutshell................no! I laughed out loud. Great vid as usual gents!
I had a mate with a lowered Capri. His drive home was through Richmond Park, those who know these roads know that there are small posts allong the road edges. One night he veered off road and ripped his underside to pieces on the posts.
Chris you are correct, it is indeed a venuri and uses the venturi effect (otherwise known as Bernoulli's principle) to create a low pressure at the venturi. At least that's the way I remember it.
The way the compressed air jet draws the air out of the cooling system is pretty much the same way the injectors on a steam engine work. Very informative bit of video there, for which many thanks - as anyone who's ever had to bleed a recalcitrant cooling system, those vacuum systems are a godsend.
I have done a coolant refill on a 2017 bmw 320i (needed new rads putting on it) which is said can only be done with a vacuum pump. it was a massive pain in the arse as i dont have one (or a compressor), i tried multiple times, raising up the corner where the tank is etc, but in the end the air lock was only occurring at the pump itself, and a half turn of the pully in the opposite direction was enough to clear it and it ran like a dream and worked perfectly after. so it is possible without the kit, but you pay for it in extra time and paracetamol (for the headaches lol). crackin vid as always
Chris you are correct about the Venturi it creates low pressure and vacuum similar to a wing and lift a carburetor has a venturi you can see Great looking project thanks for the video gentlemen
Coolant in the vehicle: G12 purple or G13 which can be purple or green. I'm guessing the lads have put G13 in there. I can see a lot of people getting overheated 'cos green coolant has gone in! G13 is the later variation on VAG's glycerine coolant. Also distilled water is better for dilution than deionised due to increased purity
👍🏻enjoy this video guys very interesting so good to see everything being put back together the right way never get bored of watching every time your on TH-cam and Instagram thank you both 👏🏻🫶🏻👍🏻
Correct Chris, Venturi effect. If a fire fighter wants to add foam concentrate (the old way), he/she would add an in-line eductor into the hydrant supplied fire hose, drop in a pick-up tube into the concentrate barrel and the force of the water running past the eductor creates a vacuum in the pick-up hose and proportions the right concentrate to create finished foam.
Yes, that's a stat for the DSG oil cooler. BTW when they fail, VAG engines never get up to temperature as the main engine thermostat is 'short circuited'.
Mint video 📹 as usual fellas coming along nicely she will look well smart when you have finished her take care and stay lucky and healthy 👍 looking forward to Wednesday's video 📹 as usual 😊❤
Nice well instructive video guys nothing like learning on the job thanks for Sharing today's vid with us , I'll be buying that pressure set up for lads tomorrow what a handy simple bit of kit !!!!. Top vid fellas
The vacuum filler does work by using a Venturi effect, similar to how a carburettor works to pull fuel in. As the compressed air passes through the unit it creates a low pressure area, this then allows the positive air pressure from within the coolant system to be draw out. ie the positive air wants to get to the negative air.
That is a great bit of kit. I wish we had something like it back in the day although systems were not as complicated then, no sensors just a thermostat and you could 'burp' the system. I think you are probably right with the roundabout theory as the exhaust has taken quite a hit and of course we know about the quarter panel. A lot of progress even if it doesn't seem like it. Nice to have it running and driving even without power steering, she sounds sweet enough. Thanks Rob and Chris for another interesting video, if you subscribe it is free people! 👍👍
Hello Rob & Chris, very interesting on the use of the vacuum to re-fill the cooling system. Oh, who walked into shot early into the video?? Engine sounds good. Best wishes from Lincolnshire.
The 'Venturi affect' was explained to me whilst studying Engineering thus: Mountaineers know not to stand in the entrance of a cave during high winds because the pressure differential between the outside and inside of the cave creates a vacuum. This will suck you out of the cave, never to be seen again.
This was never going to be a stroll in the park . Did you get a rear corner or just a new rear wing ? It's going better than it could have by a long way . Well done guys .
Round here there's been incidents where cars have been launched into the air after coming downhill at speed and hitting a roundabout - in one case, the driver lost his life but his son survived. The car landed into a first-floor flat and came to rest in the lounge, backwards.
Its coming together. Lots of fiddly little bits to get right with that sort of off roading and full engine swap out. Nice that the box is fine too. Big headache missed on that one.
The vacuum fill technique has been used for some time in the factory, it just means that the system can be filled and blead within seconds saving a huge amount of time.
I didnt realise that these need to be vacuum filled, looks like the same spherical header tank from the mk 2 golf 😊. I recall leaving the top rad hose disconnected whilst refilling, on the old VWs. Allowed the air to be displaced. When it started flowing out the top hose, reconnect it and top up the header. Job used to be a goodn back in the day. Lots of little jobs on this one, can be annoying, but has tha makins of a lovely motor.
Amazing bit of tech with the pedestrian protection system! Is that to save the windscreen from being smashed? After all, Audi screens are really expensive lol 😄😄
A person hits the bonnet and it folds under onto the hard engine top. Not much give. The bonnet raising up a couple of inches gives more cushioning before you hit the engine. I've not tried it out yet .
You know you're doing something right when you have 1000 views in 7mts.. Another great job
While doing the vacuum with silence it was good to hear the birds singing in the background one of the best soundtracks at this time of year keep up the great content
Almost at the 300k fellas.
Well deserved.
Love that you give tech information about different things to do with car engines, peace keep these videos coming. ❤❤❤❤
I love thinking back to your early videos where Chris hated been on camera to now where he’s like we have to get this on film, got his own instagram account Etc. Rob you’ve created social media monster 😂😜
Hi guys hope your both okay. Your are making a great job on the Audi. Going to be a fantastic car after you both finish your magic. Take care
Yes, it is a venturi. Nice work guys

Those engine bays ain’t half busy in these modern motors! You and Chris must have hands like pianist to work in those confined spots!
Good job gents it's going to be another great car

Well done guy's and engine sounds great looking forward to seeing the next video on how Chris tackles that rear quarter 👍
Chris's nose in and out of camera footage while filling up with coolant was funny.
Shows what teamwork does
but still a long way to go 😊
Love how rob always wears nice white trainers/shoes, if i did that i would only have pop the bonnet and they would be ruined 😁

crackin vid as always
I am learning a lot from you guys, dankie 🇿🇦
Thanks Rob/Chris -- really interesting one
Fantastic video Guys just loved it 👍
Great stuff gentlemen.
Hello Rob and Chris,the progress on the Audi Q5 is brilliant.with the parts it's running better.and it drives.
Chris you are correct about the Venturi it creates low pressure and vacuum similar to a wing and lift a carburetor has a venturi you can see Great looking project thanks for the video gentlemen
Top Guys. because of you and chris it has gave me the courage to start my own channel 🎉 much appreciated
Explanation of the vacuum system was very interesting. Thanks guys.
Hi Rob and Chris, up and running. Will be a nice car when completed, great purchase to.. Alex.

Correct 💯
Well done its a big project and lots more to do but you guys inspired me to buy my first salvage motor so here goes 🙏🙏
Another day putting in the graft . Cars coming along good . Like the vaccine procedure you did . Look forward in watching the next episode
Great video as always boy's. Keep up the good work. Cheers.

Good evening Rob and Chris, great progress again car coming on well. Thank you for taking the time to upload another video. Ged.
It really sounds sweet. The vacuum fill is an interesting process, I've never seen it done till now. 👍
Good content, nice to have a mix of short and longer projects also
All way great video Rob and Chris
Yes, that's a stat for the DSG oil cooler. BTW when they fail, VAG engines never get up to temperature as the main engine thermostat is 'short circuited'.
Great vid lads, when will folk learn other makers of coolant sometimes make it a different colour 🙄 if its the correct spec thats what matters.
Chris, a fountain of knowledge, never ceases to amaze me!
Sunday tea time sorted cheers Rob and Chris ❤❤👊🇮🇪🇮🇪🌻🌻
Great team work guys. This motor will finish in excellent order and be a great buy for one of your viewers.
Can't wait for the quarter panel repair
Great video guys, all the best Mark.👍
It's the thermostat for the gearbox oil cooler when it fails the temp gauge goes up and down Intermittently
Great demo of vacum filling cooling sys, thanks Chris :)
You can get G13 in green mannol sell it will be the correct coolant didn't know you could get G13 in green until I looked.
As many have already said get that coolant out and get the VAG pink stuff in G12/13
Mint video 📹 as usual fellas coming along nicely she will look well smart when you have finished her take care and stay lucky and healthy 👍 looking forward to Wednesday's video 📹 as usual 😊❤
I'll share this on. It's a bit late at the moment but I'll do it in the morning xxxx
Yes venturi valve - used lots in industry to create vacuum for machine to pick up stuff etc...
Absolutely Chris Venturi is correct.
Nice well instructive video guys nothing like learning on the job thanks for Sharing today's vid with us , I'll be buying that pressure set up for lads tomorrow what a handy simple bit of kit !!!!. Top vid fellas

Coffee with anti-freeze!?
You boys really are hard-core!
You and Criss make it look so easy Any vids coming up on the boat Rob ?
Super job again guys thank you! How is the boat coming along summer just around the corner...😎
I’d buy a car from these two every time I needed one.
Nice WORK GUYS GOOD Job AS ALWAYS 👍👍👍

@@sruk Couldn't find your coffee link but the £5 is for a coffee. Mark.
This was never going to be a stroll in the park . Did you get a rear corner or just a new rear wing ? It's going better than it could have by a long way . Well done guys .
That will be some motor once complete, excellent work.
feels insane to say that i've been on this channel right from the very first ferrari video, grown such a huge amount guys congrats to you

Good job rob and Chris you have to use your diag machine to put your coolant in and the steering is properly the radar not being on 👍👍😊
Great video lads,sounds lovely,looking forward to the quater panel repair.🇮🇪🇮🇪👍
Brilliant as always guys looking forward to this one 👍🏻👍🏻👍🏻🇬🇧
great job lad step closer next video please
Coming along great chaps, good work. 👍
Great stuff lads interesting filling up the coolant 👍
That is a fairly standard VAG inline thermostat used on the auto boxes. They also tend to fail open regularly.
Great video fella's Thank you.
You got to plug them in to bleed them as long as your kit will do it. easy to do takes a few mins
Great video, late watching. Coming along nicely.
Great video as always guys 🏴👍🏻
Good one, Again!😉😉😉
injector codes chaps...
keep it up
Another great video as ever. Thanks chaps👍

Great work as always guys. 👍👍👍👍
its good when you have good suppliers nearby
Iv just bought a vacuum kit, to go with my one man bleed kit, getting to old now to be messing around 👍
Well done guys
Brilliant as always!
Brilliant stuff as always you 2.
Tea time sorted 👌 in it 👌
You guys you are amazing what you do car's if i was to buy my next car straight from you honest people. Edd
Nice one boy's another great video
🎉🎉🎉ChrisThe Engine Doctor doing a coolant transfusion with Nurse Rob assisting 😊😅
Love the video ,dream team strikes again.👍👍👍
Nice video Rob and Chris
Great video guys

A person hits the bonnet and it folds under onto the hard engine top. Not much give. The bonnet raising up a couple of inches gives more cushioning before you hit the engine. I've not tried it out yet .
