List of peripheral AOS parts to replace while you are there?

Recommended Posts

Posted (edited)

I’m going to tackle my water pump, coolant expansion tank and coolant hoses and so also decided to replace the AOS.  

 

I know the AOS has several hoses attached to it. Not sure if these are coolant , oil and vacuum hoses. Just want to replace everything that is attached because I’m sure these parts are also old and brittle. 

 

Does anyone know which parts to replace that attach to the AOS and would replacing these be difficult?  Any parts names and or numbers along with any tips would be great. I’m feeling a bit intimidated by the AOS procedure but while I have everything apart want to replace everything that could fail later because I don’t want to do this again for a long time. 

 

Car ar is a 1999 C4 manual.

If you're doing the water pump you may as well add a low temp thermostat if you haven't already installed one.
