Opel Ascona A
Coolant capacity & service interval
The Opel Ascona A coolant specifications cover capacities ranging from 5.1 liter to 6.5-7.2 liter depending on configuration. Four configurations are included in the data.

Additional Notes
- The Opel Ascona A cooling system capacities vary across engine variants, ranging from 5.1 liters in the 1.2 S up to 7.2 liters in the 1.6 S, reflecting the differing thermal management demands of each engine displacement.
- The 1.2 S, available from 1972-1975, carries the smallest cooling system capacity at 5.1 liters, consistent with the reduced heat output of a smaller displacement engine.
- Both the 1.6 and 1.6 S share the same base displacement, yet the 1.6 holds a fixed 6.5-liter capacity while the 1.6 S is specified at 6.5-7.2 liters, indicating a capacity range that may correspond to different body or equipment configurations within that variant.
- The 1.9 S is specified at 6.1-7.0 liters, a range that overlaps with the 1.6 S despite the larger engine displacement, suggesting configuration-dependent variation rather than a strict displacement-to-capacity relationship.
- All four variants carry normal use conditions against their coolant capacity figures, meaning the stated volumes apply to standard operating environments rather than severe or extreme service conditions.
- The 1.6 and 1.6 S were both available across the full 1970-1975 span, while the 1.2 S entered the range later, with specifications beginning from 1972.
