Yeah, found them at iPd moments before you posted. Thanks!

(And what the heck are you doing that your CPU usage is at 100%?)

[Edit: Only one of the ones at iPd is OEM, though. Weird. I'll check with my local indie to see if he can supply OEM.]

Saving the world, duh! :roll:

Usually you can call them up and request OEM parts with your order and they can get em for ya. I used a lower radiator hose (which is a pain to get in) from URO, and within 2 weeks it was leaking at the radiator. So I'd tighten the clamp...it worked for a bit, then repeat. The walls are too thin to hold pressure at the lip.

I was having the same symptoms as stated in this blog thinking I had to change the radiator again (Dealer found that leak, and fixed it on my extended warranty to their surprise) this time it was the expansion tank where the BIG hose is connected. The plastic tank with a metal bushing inside the plastic outlet has several small cracks in it. Se picture below. Bought a new tank and changed it in about 15-20 minutes and it is all good. :D

Over the past year I've had to replace both a tank and cap on my 2002 S80. Craks and slow leaks, the plastic just goes after time it seems. Luckily an easy fix.

I too am having this problem with the coolant leaking from the turbo inlet hose ( PN # 6842190 ). I was able to locate it after several minutes of just shining a really bright work light down there and finally seeing the actual problem with coolant leaking from both ends of the bulging, aging hose.

Not to mentioned oil soaked. Get only OEM or aftermarket silicone hose to replace it. do88 is a great option.
