Volkswagen Engines in the 90's
The 1990s saw Volkswagen engines in a state of transition. For almost fifty years, Volkswagen engines had been air cooled—a cooling method that employs a forced airflow directed towards a series of fins on the heads and cylinders of the engine, causing transfer of the engine's heat to the air, and consequently temperature reduction. Although these Volkswagen engines were lighter and less complex, air cooling systems were found to be inefficient and resulted in a considerably shorter engine life span.
