[s-cars] Coolant expansion tank connection

[chris chambers]

Alan,

Welcome to the S-car list!

The tank is plastic and the "nipple" is the steel insert you see
with plastic around it. 

This is a common problem, and there is no "fix"...btdt, simply
replacement of the tank.

I'd call http://www.germanautoparts.com/ at 1-877-443-7626,
they normally have good prices.

I am sure others will recommend other good sources for this part.
