Blown Nogaro

I have spent like two hours trying to find the source of coolant leak that I noticed two days ago. It has turned out to be the cracked expansion tank. I'm planning to replace it myself but does anyone know its part number for '00 S4? And I don't think I need to flush the coolant system to remove air because the coolant expansion tank is at the highest level. Am I right? Any tips or things to be cautious of would be greatly appreciated.

Thanks in advance!!!

spent about $75+ for the tank and that Audi pink fluid. When you drain the coolant, make sure you get that hose on there tight by the AC condensor.

remember to buy a gallon of coolant along with the tank. (I used about a 50/50 mix of coolant and distilled water)

if you choose to drain the coolant, remove the belly pan and pull the hose to the left of the radiator bottom (passenger side). Make sure when replacing the hose to secure the clip that holds it on.

its a shame that the coolant tank doesn't come with a new cap.

P. Bauer

for $75 bucks, it should...

I can use the existing cap, can't I?

P. Bauer

unless it's damaged, yes you can.
