PLASTIC TANK RADIATOR REPAIR
We still repair aluminum core radiators, whether they have plastic or aluminum tanks!
In 1977, Volkswagen made an innovation that would forever change the cooling system industry. In order to keep their Rabbits lighter, VW made many developments, one of which was to make their radiators out of aluminum instead of the traditional copper and brass. The new design was quite radical and frankly, not very good. Rather than making aluminum side tanks and attaching them via aluminum welding, an expensive process that would require skilled welders, they chose to attach tanks made of a nylon blend with very weak tabs on the header of the aluminum radiator core. In order to prevent leaks, they they put a rubber gasket between the core and "plastic" tank.
