Re: [alfa] Alfetta cooling problems

Stefano, do a compression check, this will show you if you are leaking
combustion gas. Also run the car with the cap of and look for a steady
stream of bubbles rising to the top of the radiator,another sure sign of a
combustion leak into the water jacket. The heads do crack but it is not very
common, if however this is the case fit a new head, dont bother with having
the old one repaired.
