Default Coolant leak - 2002 Audi A6 3.0

Hello,

I have a 2002 Audi A6 3.0 and love it. No problems with the car since I got it. Now that it has 117K miles I see problems cropping up. My coolent started leaking a couple of days back. It's dripping after I drive for a while and stop. It leaks till the engine cools down. At least that's my guess. I suspected a water pump problem but the car doesn't heat up when I drive it.

Did anyone else have this problem? I am planning to also change the timing belts so is it OK to buy parts online like Bosch or Continental or should I go to the dealer for these? Any advise is greatly appreciated.

I had that problem with my 2000 A6. I noticed that the Reservoir tank had a few hair line cracks in the bottom of it... I got some plastic weld to try that, but that didn't help. So i just went and bought a new tank for it, and that solved my problem. Hope that helps!

Thank you forknif. I looked at the reservoir but there are no cracks or leaks from it. The leak is right under the belt next to the oil filter when looking from top with the hood up.

Thank you for the advise and I'll look at the reservior again just to make sure...

ya i noticed I had a ton! of dried coolant right under my tank, so i knew it was coming from there, you might have a loose clamp somewhere.. but anything past that, good luck! i hope someone has a solution for you

Pay attention to the quality of new water pump in the TB kit.
Some report the water pump problems within a year after TB service.

Thank you so much for your post! The first link you sent that's exactly where I have a leak from. I think I'll go get the impeller today and hopefully fix the problem.

Thanks again!

Bringing this thread back from the dead ... My wife's 2002 A6 3.0 has developed a very small leak on the front, middle area of the engine. I pulled off the plastic undercarriage guard and wiped everything down to see a source of the problem. Nothing is jumping out at me, until I saw this link: http://www.audizine.com/forum/showth...s-Is-it-normal

I want to see if this is the problem, but I can't find where the therostat is based on the pics.

My wife is taking my car tomorrow, so I'll drive around and see if I can force the issue and get a bit of a leak to show up. I had it idle in my driveway for about 20 minutes and it was dry as a bone under there. No coolant in the oil either, no loss of power or smoke out of the exhaust (phew). Thanks for the help!
