English · machine-assisted draft

An engine that rejects heat directly to moving air rather than circulating liquid coolant. Gerry’s spark-plug reference separates bus applications by engine code and period: ED/GD/GE for 1975–1979 and CV for 1980–1983, including California models. A May 2002 Gerry discussion titled “83 Air Cooled - Production dates” concerns an owner’s September 1983 Westfalia and the difficulty of finding comparable 1983 examples; it is a period-specific production question, not a universal fitment chart.
