Hi guys,

I just discovered a small crack in the bottom of my coolant overflow reservior on my A6. I know I can get a replacement for under $100, but I'd like to repair it with plastic epoxy/JB or a similar compound. Can anyone make a recommendation as to which product(s) I might use for this application based upon experience?

Thanks!

 

Black or red RTV is all you need, but let it dry before your add coolant back in.
