Additional Notes

  • The Volkswagen Cabriolet 1.8 carries a cooling system capacity of 4.6 liters across both the 1984-1989 and 1989-1994 model ranges, reflecting a consistent system volume throughout the full production span covered by these specifications.
  • A 4.6-liter cooling system capacity is a moderate figure for a 1.8-liter inline four-cylinder engine, consistent with a system that includes the engine block, cylinder head passages, radiator, and heater core circuit.
  • Both the 1984-1989 and 1989-1994 Cabriolet 1.8 configurations list the capacity under normal use conditions, meaning the 4.6-liter figure applies to standard operating environments rather than severe-duty or first-change-only scenarios.
  • The 1989 model year appears in both row entries, as the 1984-1989 and 1989-1994 ranges share that year, yet the specified capacity of 4.6 liters remains identical across both, indicating no change in cooling system volume at that transition point.
