Morgan All models
Coolant capacity & service interval
Morgan All models use coolant with a capacity range of 10,2 to 13,5 liters. Service intervals require checks every 8000 km or 6 months. The data covers 4 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- The Morgan Plus 8 (1981-1993) carries a cooling system capacity of 13.5 liters, which is notably larger than the 10.2-liter figure shared by the 4/4 1600 and Plus 4 16 valve models, reflecting the greater displacement of the V8 engine fitted to the Plus 8.
- The Morgan Plus 4 (1985-1988) lists a cooling system capacity of 10.22 liters under normal use conditions, a figure that differs only marginally from the 10.2 liters recorded for both the 4/4 1600 and the Plus 4 16 valve.
- All four configurations share an identical service interval of 8,000 km or 6 months for a coolant check under normal use conditions, regardless of engine type or model designation.
- The 8,000 km or 6-month check interval is a relatively short cycle by modern standards, consistent with maintenance practices common to vehicles of the 1980s and early 1990s.
- The Plus 4 16 valve (1988-1993) and the 4/4 1600 (1981-1990) share an identical cooling system capacity of 10.2 liters despite representing different engine configurations, one being a single-cam unit and the other a twin-cam 16-valve design.
- All specifications across the four configurations are recorded under normal use conditions, meaning the listed capacities and intervals apply to standard operating environments rather than severe or demanding duty cycles.
