Additional Notes
- The Porsche Boxster 981 (EU) cooling system capacity is 23 liters across the standard Boxster, Boxster S, and Boxster GTS variants, covering model years 2012-2016 and 2015-2016 respectively.
- A 23-liter coolant capacity is notably large for a mid-engine sports car, reflecting the distributed cooling circuit architecture required to manage heat across the engine, radiators, and ancillary systems.
- The Boxster Spyder (2015-2016) carries a 25-liter cooling system capacity, which is 2 liters greater than the other 981 variants listed in the same generation.
- The 2-liter difference in the Boxster Spyder's cooling system capacity suggests a physically larger or differently routed cooling circuit compared to the standard, S, and GTS configurations.
- All four variants share an identical service interval of 24 months or 30,000 km under normal use conditions, whichever comes first.
- The 24-month/30,000 km interval is classified as a check rather than a full drain-and-fill, meaning the service action involves inspecting coolant condition and level rather than a complete system flush.
- The interval structure combining a time-based limit of 24 months with a distance-based limit of 30,000 km means low-mileage vehicles still require a coolant check within two years of the previous service.
