Cooling Flange Damaged the Engine?

[paulerolland]

Hi,

Monday morning, my A4 B6 coolant light came up. I checked and the coolant was completely gone. I refilled the coolant with distilled water that I had at home and drove the car to the garage shop that changed the rear coolant flange a year and a half ago. Once there, they took it apart and send me this picture:



Apparently, and I checked on the car, something has been banging or eating (chemicals?) the metal, preventing the cooling flange gasket to properly seal.

Did someone ever experience this? They are trying to seal the flange back with some silicone based gasket but the first time failed the pressure test.
Are they potentially responsible for the damage since they changed the coolant flange and the coolant itself?

Thank you!

Your gonna have a hard time proving the garage did something wrong almost 2 years ago.You do realize theres a o ring that fits onto the rear coolant flange correct??

That's some real cell block 4 sh*t for you. Haha

Sorry for the joke, but I am on my cell phone and made me chuckle once I realized what I was looking at. Buy OEM flange or metal upgraded one. Aftermarket ones warp over time faster than oem. But sanding flat flange seal area and replacing o ring may do the trick. I keep assortedbo rings in me garage.

But if replacement flange is not oem...fingers pointed. But you should have requested that, if you did not. They can use whatever supplier they choose. Many around here use the local Keystone. They can use Autozone all day if they wanted to. Warranty disclosure should be printed on the invoice...that you signed. And most would be like 6 months labor and 1 year parts (no warranty if part supplied by customer), or really whatever they choose. So this way manufacturer covers part and they cover themselves with overhead cost with labor with ethics. As mentioned above, no way to go after them.

That sucks man going through the same thing on the b5 the coolant flange has come off twice now but its fucking pissing out im ordered the oem flange from ecs and will be going to the local vw dealer to pick up another bc im sure ill need it thinking about picking up some gasket material cutting it to size and adding permaseal we will see...gd luck man

I've seen it a few times on the B5 1.8T engines. Clean it, dry it and fill it in with JB Weld. Make sure it is flat, block sand as needed.

Yea there is no room back there i just used peramatex the right stuff and it seems to be holding after 20 min of driving semi aggressive. Let the silicone sit on the flange for 2 min before you attempt to finagle it to its location this will make it semi hard also stick your left hand in the flange area before to get acclimated

This may be a mood point buy now but here goes. Im pretty sure using distilled water will eat up certain minerals in metal and almost anything else. Hope you didn't leave it in there.
HAPPY HOLIDAY

you may be confuse, using tap/city/well water will cause corrosion on certain bi metals found in our engines distilled water is recommended because of the distilling process which is in a nutshell collecting vapor from sterilized water i actually used well water in a pinch and noticed thick white foam in the coolant res. once flushed i added 60/40 g12 and distilled water without any more foaming. Coffee makers also suggest using distilled water machines b.c of sediment buildup that is known to occur when using city/ well/ treated. I actually prefer distilled over well water.
