AUDI A4 1.8T "COOLANT FLANGE" HOSE PART 2

[@nicksgaragenixx-fixx7911]

I am fixing and repairing the same exact parts on my 2004 A4 1.8 T Thanks for the very good quality and informative video’s

Done. I did this job over the course of the week... little by little after work and finished it up on Friday. It really is a piece of cake with only a few scratches, a slightly sore back from leaning over the car. The reason it took so long is that I took the time to clean all the bits I removed etc. I believe it had been done before as the flange I took off did not have any VW or Audi stampings on it, but is did however say “made in Germany”. Unfortunately and totally my fault is that I did not buy an OEM flange..didn’t really think about it at the time I ordered the parts. Then come to find out there is also an aluminum version but I really need the car for my weekly commute. Bleeding the air out of the system is super easy, though my bleeder is located on the hose attached to the heater core. Fingers crossed she is holding the coolant 🤙🤙🤙👍👍👍🇩🇪🇩🇪🇩🇪
I did take too much video of the process but I did take some snaps with my phone. I suppose I could put together a slide show and post it here ..but honestly there are many so guess there is no need :)

Great job. If you didnt put a factory part in no big deal. Just keep a close eye on it... it is back breaking work but you saved a boat load of money on labor! TRUST ME lol

[@TopSecretVid]

spraym 88 True on the money savings part ..though I did rent a car for the week..haha. Not really sure how much a shop would have charged but I think it was good to do the job myself as I don’t think a shop would take the time or care to clean or almost detail the back of the motor. Im glad I did it. I have to inspect the flange that I took off as there were no visible cracks so Im thinking the gasket/ O ring might been the culprit. Though that looked to be in decent shape. The O ring did however remain on the engine block when I removed the flange. Im really getting to know this B5 wagon intimately ..

been watching a lot of videos like yours..thanks for making them :).

Thanks for tuning in. Hope it helps. I've learned that with these 1.8t motors, as long as you go with genuine Audi parts, your good!

[@deserteagle6207]

Dude u literally saved my Life !! Thank you

[@spraym88]

Haha Thank You for tuning in. This car is a struggle to work on. Glad these videos helped

[@barbaratodd1288]

Great video I’m about to replace the flange on my 03 Passat wagon. I’m going with the cast aluminum from ecs tuning. I’d like to add the importance of using distilled water if you’re not using a premixed coolant. Distilled water will lessen deposits in your cooling system and hopefully will keep the dreaded heater core from needing replaced.

[@gingefpv]

I've just ordered the aluminum flange from UROTuning i can't wait to install it.

[@barbaratodd1288]

@@gingefpv I'd suggest you change the coolant sensor while you are in there

[@spraym88]

I would honestly go with an OEM Audi part/ parts... . I tried going with the ECS TUNING parts twice. Both times they failed fyi!

[@gingefpv]

@@barbaratodd1288 I’ve already done it. I had to change it. But I’m worried the leak I had has gotten worse. I was told by my shop that they had changed it. If I need the oem Napa has it for $33

[@israel7294]

Does the oring suppose to sit in the the flange where it got the carve at? The oring that came with part is like a half an inch to big to fit in..same with the one I took of...it look like the o ring was in at first when I took the old flange off..but once I took the o ring out of the old flange it didn't fit back in

[@nedoscarsandfishingvideos5500]

You can tell this guy like this car haha nice video

[@joecharron3984]

Thanks for the video bro.

Your Welcome bro... Thanks for tuning in

[@etienneeloitine2090]

Heyy buddy , really good video
Actually i have the same problem with my Audi A4 1.8T 2003, i already get the part too but with only one ring on the new part
Should i get one or two rings?

[@spraym88]

Hey man thanks. Ok What ring are you referring to?

[@etienneeloitine2090]

@@spraym88 on the new coolant flange part they’re usually have a plastic ring, mine only have one but when i made searches i saw 2 on that old part,
Should i remove the old ring from the past part and put it back for the new coolant flange?

[@TopSecretVid]

When you are filling up the coolant with the bleeder screw open..are you doing this while the engine is not running??.. doing this job as I type this on my 2003 Passat wagon..The flange has been leaking for weeks...

[@spraym88]

Yes. Fill it with the engine off at 1st. While filling the reservoir with coolant, keep a close eye on the bleeder screw on the coolant pipe. Once coolant flows from the screw constant, tighten the screw then start the car. Rev the motor to 2500 to 3000 rpms until it gets to normal operating temp. Put your heat on high, keep.feeling the vents until you feel heat

[@TopSecretVid]

spraym 88 doing this job after work so my hope is that by Thursday I am at this step!!. Fingers crossed all goes well.

[@spraym88]

@@TopSecretVid goodluck. You can do it. My advice to you, be very very patient.

[@nicksgaragenixx-fixx7911]

The only thing I wish you would have showed is how and where you routed the coolant or breather tubes as you called them ( there are two tubes ) one of them gets mounted to the “y” tube and the other small steel tube goes to the other side of the engine into a small 3/8”i.d rubber hose.
I am not sure how to route it ? If it goes between the combi valve and against the engine block to the other side of engine or perhaps in front of the combi valve and around the coolant flange it does in fact have a flat mounting tab on it to mount it to one of the holes in either the combi - valve or maybe through one of the hole on the coolant flange. (I am NOT SURE) any thought on this?
I am putting this back together today so I will make it work but wish it was on this video as it is very difficult to re-route to make it work without removing the combi-valve any maybe coolant flange again as you know these are a bitch to get all the bolts in and tighten them up ( very tedious work)
Thank you for the Video in any case!

[@spraym88]

Ok did you take it apart and just forget? Only treason I'm asking is because the pipes can only go back on one way. 2nd, do you have a quattro, motor facing forward or just a fwd?

[@TopSecretVid]

Do do you loosen to turbo cooling line?

[@carlosmaldonado5528]

Me too bro!!you’re video was very helpful thanks.i also need that hose or can I buy the quick connector separate??

[@spraym88]

carlos maldonado quick disconnect comes molded to the hose...ECS Tuning. Thanks for tuning in

[@spraym88]

carlos maldonado don't use the ECS TUNING hose. It failed twice on me.... Get the hose from the AUDI DEALER

[@phalanx66Satan]

Well done, I think I have the same problem here with a bad hose because it just drains out from back there without any pressure (engine off) whatsoever. I'm going to go to the junk yard and rip apart one there for practice. I was wondering if there is enough room to get your hand in there without taking everything apart to remove and replace the coolant hose that goes to the lower heater core inlet you talked about?

[@spraym88]

Lance Dixon No room whatsoever without removing everything I removed in the video. Its actually not that bad. Just heat up all of the hoses with a heatgun to remove the pipes so you don't crack them

[@gregorythoman8281]

Nope

[@djgaryg]

It can be done without removing everything . Just have to be patient and feel around. I have a 2002 Passat same motor. I did the flange about 2 years ago (removing everything) and replaced the heater hose at that time as well. Didn't use genuine VW / Audi hose, and it started leaking from the hose a few weeks ago. I was able to get it out and replace it, removed nothing, just cursed alot haha!

[@israel7294]

​@@djgarygdoes the o ring sit perfectly in the flange? My o ring seems a bit bigger don't fit in where it's suppose to

[@djgaryg]

@@israel7294 hard to remember, but I think it did. side note I still have the car, just crossed 300k miles this fall

[@erickkraft1605]

thats exactly what i need. Do you happen to have the part number for the hose and the coupler? how much total did the dealership charged you for?

[@spraym88]

Johnny Thrust got the parts at ECS TUNING! thanks for tuning in

[@spraym88]

Johnny Thrust $65 from Audi dealer

[@alexisapriliasxv5509]

OEM part number????????????????????

[@michaelbarrett3746]

What is the name of the hose?

[@peggyjones4036]

Could you maybe help me? I took my car to Dobbs and it same back missing on all four cylinders and a random miss fire code, it’s also covered in oil around the coolant flange, I took it in for a coolant flange and it came back trashed

[@peggyjones4036]

Not to mention it’s running lean is what my scanner says and the check engine light will flash sometimes

[@spraym88]

No idea. . They did something wrong

[@peggyjones4036]

spraym 88 dang, it’s been a year and they kept avoiding the issue, I’m clueless I replaced the coils and plugs for the missfire and it didn’t do anything

[@spraym88]

Check the vacuum lines. They crack easily. They might have cracked one on accident not know. Car will run like shit....

[@gregorythoman8281]

Is there a o-ring inside the quick disconnect?

[@spraym88]

Yes there is. You should definatly put a little grease on the new o-ring/hose. It clicks into the flange with a little metal locking clip that's attached

[@gregorythoman8281]

Yes, but the new hose should come with a new one. They tend to get very brittle.

[@spraym88]

@@gregorythoman8281 you need to REWATCH the video and or reread my reply. I said put some grease on THE NEW o ring

[@KECIKKCHANNEL]

if coolent leak , did the car got smoke and did car feel like misfire ?

[@spraym88]

No misfire, just temp very high

[@KECIKKCHANNEL]

spraym 88 would you give your email because i need to show you something and its about area you have show in your video 😊

[@gregorythoman8281]

Sorry, not really helpful. I wanted to see you remove and replace the hose not show before and after.

[@spraym88]

That's the easiest part theres a pin at the connection. SIMPLY pull the pin out, and pull the hose DOWNWARD
When you REINSTALL the new hose, it SHOULD ALREADY HAVE the locking pin in it. All you have to do is push it in place.
