Vauxhall Cavalier II

Coolant capacity & service interval

Vauxhall Cavalier II coolant capacity ranges from 6,3 to 7,9 liters. Service intervals include checking every 500 km and changing every 24 months. The data covers 4 configurations.

Additional Notes

  • The Vauxhall Cavalier II 1.6 petrol carries the largest cooling system capacity across the four engine variants at 7.9 liters, which reflects a greater total fluid volume within the engine block, cylinder head passages, radiator, and associated hoses compared to the smaller displacement engines.
  • The 1.3-liter variant holds 6.3 liters of coolant, the lowest figure among the listed engines, consistent with the reduced block size and shorter coolant circuit typical of a smaller four-cylinder unit.
  • Both the 1.6 D diesel and the 1.8E share an identical cooling system capacity of 7.5 liters, despite differing in displacement, fuel type, and available years.
  • The 1.6 D and 1.8E variants each entered the specification range later than the 1.3 and 1.6 petrol, with the diesel appearing from 1984-1985 and the 1.8E from 1983-1985, while the base petrol engines span the full 1981-1985 range.
  • All four engine variants share a 500 km initial check interval under normal use conditions, indicating that coolant level verification was expected very early in the service cycle, likely to account for air purging and minor fluid loss during the first heat cycles after a fill.
  • The coolant change interval is set at 24 months across all listed variants under normal use, meaning the service schedule is time-based rather than mileage-based for the drain-and-refill procedure.
