Sunbeam Alpine

Coolant capacity & service interval

The Sunbeam Alpine coolant specifications cover a capacity range of 7.1 to 11.4 liters. Six configurations are included in the data.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Alpine (1953-1955)
  • Use: Normal
  • Capacity 11,4 liter

Additional Notes

  • The Sunbeam Alpine (1953-1955) carries the largest cooling system capacity across all listed variants at 11.4 liters, a figure consistent with the larger-displacement engine fitted to that generation of the model.
  • The Alpine Series I and Series II, covering 1959-1963, share a capacity range of 8 to 8.5 liters rather than a fixed value, reflecting minor variation that could arise from differences in coolant fill procedures or component tolerances within those production runs.
  • The Series III (1963-1964) settles at a fixed 8.5 liters, representing the upper bound of the range seen in the two preceding series and suggesting a standardized fill specification for that variant.
  • A notable reduction appears with the Series IV (1964-1965), where the cooling system capacity drops to 7.1 liters, a decrease of roughly 1.4 liters compared to the Series III, which points to a change in engine or cooling system architecture between those generations.
  • The Series V (1965-1968) shows a slight increase to 7.2 liters relative to the Series IV, a difference of 0.1 liters that likely reflects a minor revision to the cooling circuit rather than a fundamental redesign.
  • All six configurations carry a normal use condition, meaning the listed capacities apply to standard operating environments without a separate severe-duty specification present in the data.
  • The gap between the 1953-1955 generation at 11.4 liters and the later Series I onward at 8 to 8.5 liters reflects the substantial difference between the original Alpine body platform and the entirely new smaller-bodied Series that debuted in 1959.
