AUDI A4 1.8T "COOLANT FLANGE'' HOSE!!

[@GCS88]

Thanks for this video, I'm facing the same issue now but will be doing an upgrade, I bought an aluminum flange and welded an AN12 male on where the heater hose goes then cut the broken part of the hose and use a push-loc AN12 female

[@theoracle2877]

Just had my 1.8T passat done by a local garage. They put in a new Temp sensor while it was easy access and they also fitted a new rocker cover gasket as these leak at the back and can go unnoticed . £280 all in which I think is a fair price👍🏻

[@Don.of.]

This was really helpful for me to understand how the heater hose worked. When I initially diagnosed the issue, I had thought that the hose simply slipped off, and needed a new clamp. That seemed to worked for all about 5 minutes until the car hit a pull, and the hose popped right back off. Now watching your video I see the hose itself needs a quick connect on it which it is missing. So I need a new hose assembly. Many thanks!

Glad it helped out

[@orlandoharriott8453]

Great diagnostic!!

[@spraym88]

Thank you Sir

[@zacjohnson8404]

I got this problem (not the hose but somewhere in the vacinity) and it's sucking a tiny bit of air into the system

[@v8trax]

how many hours of labor did the tear down and reconnect of everything take? @spraym88

[@spraym88]

It took me over 2 hours tear down time the 1st time I did it! Then the aftermarket part failed so the 2nd time it took me roughly an hour teardown. Reassembly a bit more

[@josedejesusgonzalezalvarez2221]

does anyone know where is located coolant bypass valve. the scan is giving me error 15462. i have an audi a4 1.8 2013. if anyone knows let me know please

[@spraym88]

Never heard of it bud....

[@sheeshjamz]

Is this the same as for a 2001 Audi A4 1.8T? I have an AWM engine, just recently found out coolant was leaking at the back of the engine when I started smelling something sweet.

[@spraym88]

Delusive I'm not too sure. If I'm not mistaken the 2001 is still the B5 platform. 2002 starts the B6...

[@spraym88]

Delusive more then likely it's a COOLANT FLANGE OR HOSE!

[@sheeshjamz]

I tried looking to see where the leak is coming from but just can't pinpoint it, I bought the upgraded cast aluminum one to prevent this from happening again. So crossing fingers it's just the coolant flange and not a hose.

[@spraym88]

Delusive Get a light and try to look at the TOP of the transmission to see if its WET! If it is, it's the flange AND or the flange hose. My advice would be to use ONLY a genuine Audi part. I've used after market ones before and trust me, IT WILL LEAK again

[@YeymyBeCute12]

So I took off the coolant flange to replace it but that part of the coolant hose connector broke inside the hose. What do I do now 😭

[@spraym88]

You have to change that hose

[@tsoukallos]

My friend a question: at 4:28 that upper plastic part with the metal clip, how did you disconnect it from the coolant flange? I’ve pulled the clip out as much as it goes and tried pulling it off the coolant flange. Won’t budge after 30min of trying. Help!

[@spraym88]

Once you remove the clip, you got pull on it with force

[@spraym88]

3:28? Or 4:28

[@tsoukallos]

4:28 top part of coolant hose. I thought I didn’t have to remove the clip all the way. Thanks man. Appreciate your help.

[@israel7294]

Trying to find the water pump on this exact engine... i had a leak from i think the flange..it was fixed..but on the driver side of the car all i see is oily lookin stuff and maybe coolant because car still over heating...i kno heater hose dont shoot out oil so im tryna figure out wat it is,is it a water pump??..its also looks like a cap is missin at the drive side of the engine at bottom by oil filter and dipstick...but the engine cap is to the passenger left side of the engine so i dont kno what cap is missin on right side .if anyone could help???

[@spraym88]

Water pump is internal! Next to timing belt and tensioner

[@pbSangaroon]

Hi. I have A4 1.8 T X reg. (2000) . I have the problem of finding the Coolant Flange Hose! Any advice would be highly appreciated. Thank you. Pat B.

[@spraym88]

Pat B. ECS tuning has it

[@pbSangaroon]

Oh, you're in the USA.

[@n9wox]

I bought the cast aluminum coolant flange from ECS tuning.

[@lure68]

Hay bro thanks for the video info . I have the same problems with my 2004 passat 1.8t. , how did you take off that hose . Hit me up and how much did it cost you? Thanks

[@spraym88]

Jose Sanchez jr the easiest way to take the hose off is to remove everything I removed in the video! It goes underneath the firewall to the heater core

[@lure68]

Cool thanks bro

[@mauricioskater4]

Just did this on an Audi but if you have long hand you’ll get away with not having to remove the combi-valve

[@rzyao64]

i was able to get a ratcheting wrench back there, it was tight and i hadn't taken out anything because i was planning how to do the job, but it is possible if you can fit your hands back there

[@Jayz689-]

Hi i changed my one today, it start at first with a blinking engine light then when i restart it wont start anymore. Any suggestions whats wrong?

[@spraym88]

Not quite sure man. I didn't have any issues starting

[@Jayz689-]

@@spraym88 all good then, probably the coolant sensor is faulty

[@jaybag5652]

Wish you would have put link for the hose at least

[@spraym88]

Jay Bag all you have to do is Google 2002 Audi A4 B6 coolant flange hose to heater core

[@timmer421]

Ha! my 05 A4 1.8t hose broke at the same spot next to the clamp. New hose, Problem Solved!

[@spraym88]

Haha Nice job

[@zlatkofilipovic1509]

I can't see Why you take away air filter box ? You can change that hose without taking down air box ?😏

[@spraym88]

Great tip. Thank you for that

[@Miltonbosss]

So don’t buy from ECS tuning?

[@spraym88]

Yes you can buy from there. Just buy GENUINE Audi parts. I've had no luck with ecs tuning parts

[@streezyrider121]

This video would have been more helpful with a PN in the description as the other guy said. For anyone in the future who does get to this point 8E1819371B OR CHH0167R You're welcome

[@spraym88]

Kevin K this is a DIY video... I clearly tell you where to get this part.... if you want me to fix your car for you as well why don't you just bring it over... this is KZbin and if you don't like the video search for another one... it's so sad that certain people have so many negative comments but yet you're looking for help on KZbin if you know so much, maybe you should make your own video for people like US to learn from

[@streezyrider121]

Funny, maybe you ought to have replied with a thank you for the PN addition. My comment could hardly be viewed as "negative" and it's not like I down voted the video.

[@spraym88]

Kevin K you're right I appreciate you uploading the PN . In the video all I said was I was not going to get one from ECS Tuning because I already had two fail. I also clearly said I was going to get an Audi genuine part and since I didn't look up the part or purchase it yet I did not know the PN. Thanks

[@spraym88]

Kevin K again this is KZbin and we are all trying to help and learn from one another.. thanks for tuning in

[@streezyrider121]

Fair enough. I just had a lot of trouble finding the PN myself. I had actually ordered the wrong one being most places aren't using the correct display pictures and I wasn't finding any model specific diagrams. ECS also offers multiple options that arent for your application even when specifying your application. Frustrating search. Either way, the video did help me out and I hope the PN options I posted also help folks out.

[@wenzenuf221]

Guy sounds like trump lol

[@spraym88]

Haha Thanks. I think lol

[@travelsworld7920]

Let me tell you and you are smarter than Jesus dude.

[@spraym88]

Not sure about that man but thank you 🙏
