Additional Notes
- Across all five Triumph Herald configurations spanning 1959-1971, the cooling system capacity is uniformly listed at 4.8 liters under normal use conditions.
- The 4.8-liter figure represents the total cooling system fill volume, which typically accounts for the radiator, engine block water jackets, heater circuit, and connecting hoses taken together.
- The Herald 948 was produced in two distinct power outputs, 25 kW and 29 kW, both sharing the same 4.8-liter cooling system capacity for the 1959-1964 period.
- The Herald 1200 carries the same 4.8-liter cooling system capacity across its 1961-1970 production span, indicating no capacity revision was introduced despite the engine displacement increase over the 948 variants.
- The Herald 12/50, produced from 1964-1967, and the Herald 13/60, produced from 1967-1971, both retain the 4.8-liter cooling system capacity, showing consistency across the higher-specification variants of the range.
- All capacity values are associated with normal use conditions, meaning the 4.8-liter specification applies to standard operating environments rather than severe-duty or high-temperature service scenarios.
