I have a a4 2.8l 30 valve atq motor that I did rebuild on, rings ,rod bearings one new head new gaskets both sides, timing belt kit w/waterpump & new thermastat. It purrs like a kitten, problem is that it keeps over heating only the drivers side hoses get hot, it will get hot, when turned off all the coolant in the resiviour will diappear. There are now leaks anywhere. has any one had this problem and whats the cure....vapor lock what? Im stumped.....help.

 

This may be a dumb question, but did you add the extra amount of water and burp the cooling system afterward?

I believe it's 1 jug of G12 and 2 more jugs of water/distilled water, but don't quote me on that.

A possible disconnected hose?

 

As in bleeder screws ....no that is something I will try tonight.
