Re: Help! 156 Radiator elbow
Did you pull the metal strip out? I pulled the metal strip out of mine but I managed to thread it back in. There should also be an O ring in there to seal it. I put a jubilee clip on the outside as well, as a belt and braces measure.
You might have to buy another, the only problem is it is an Alfa only part and comes with the hose attached.
If the clip hasn't been pulled apart it should be just a push fit onto the bottom of the rad.
