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.
| Type | Specifications |
|---|---|
| Alpine Series V (1965-1968) |
|
| Alpine Series IV (1964-1965) |
|
| Alpine Series III (1963-1964) |
|
| Alpine Series II (1960-1963) |
|
| Alpine Series I (1959-1960) |
|
| Alpine (1953-1955) |

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.
