I have a leak and it looks like it is coming from the top of the radiator. The water runs down and collects in a creavis on the fan shield. The top of the radiator has a metal or plastic that runs all along the top. It is held in place by some bent metal. Can I fix my own radiator? I don't want to pay $$$ for a new one.

Anyways it looks to be an easy job to take the radiator out. But once it is out how about fixing it with?
