looks today that when i came back i saw steam coming from underneath the hood..so i popped the hood and saw a coolant hose leak (close to the firewall) a little bitty stream making a lot of steam ... anyway you can fix a hose like that? there is no close by audi dealer here and the autozone doesn't have those hoses i bet.. anyone ever just fixed a little leak like that?

The system is pressurized so I wouldn't go about rigging it up.

ok i found one of the coolant lines that didnt seem connected right. It has 2 10mm bolts in it close to the firewall behind the cylinderhead. I had to remove the reservoir to get to it and tighten the 2 bolts twice. It stopped leaking. I felt the hose to and from the radiator and it feels empty.. i hope it is pumping coolant around like it should.. it might take a while again to build up pressure after you fill it back up?

it builds pressure when it gets hot. keep an eye on the level as it heats up, you can 'burp' the hoses to help get trapped air out of the kinks + low spots [squeeze them]. BE CAREFUL - eye protection and gloves at least - boiling coolant is no fun to have sprayed on you.

sounds to me like you need this:

make sure you get ALL new gaskets [4 - temp sensor, blank sensor bung, flange to block and metal pipe to flange]. also it's typically the gaskets that go and not the flange, but it's 5$. it's one of those every 100k mile things.

also make sure you use the correct coolant and no mixing!

oh lord, I replaced all that right before I sold my car. what a pain in the ass. I had to get like 3 different ones because the first two were slightly warped and didn't fit against the head flush. plus the rubber o-ring gaskets didn't fit right etc...what an effin nightmare.

DUDE! the EXACT same thing happened to me ! i went through 3 of them as well b/c the first 2 were warped slightly!

i finally got a dealer part for like 25$ that did it. the aftermarket ones i was getting just didn't cut it. NIGHTMARE. it should have been a 20 minute job but wound up keeping the car down for like 2 weeks [mailorder parts].

yep same for me. another thing i noticed was to loosen the metal pipe mounts at the front if the intake manifold when you tighten it to the flange. then tighten the pipe so it doesn't un-seat the flange.

Wow, I never thought I'd be so glad that I got the expensive one from the Dealer the first time!! I'm glad I didn't have to go through all of those nightmares!!
