You have it all wrong. There is nothing inherently wrong with the origional radiator with the plastic tanks. I only mention it is plastic because if the one in your car IS the one with plastic tanks it is probably the origional and is over 25 years old. If it has metal tanks we have to assume the radiator was changed at some point in the past. The plastic tanks were crimped on. The most common failure mode of the radiator with the plastic tanks is corrosion building up between the tank (the one on the left where the hottest coolant enters) and the core. It loosens the crimp and it starts to leak. My point is ANY radiator, metal tanked or plastic, is not meant to last 25 YEARS! As for those of you "slamming" into "immovable objects" Try stopping a little sooner!
