Additional Notes
- The Reliant Robin cooling system capacity is listed at 2.84 liters across all four configurations covered in the 1972-1981 specifications, with each entry carrying an additional "(+ heater)" notation indicating the heater circuit adds volume beyond the base figure.
- The 2.84-liter base figure represents the cooling system fill without the heater circuit included, meaning the total coolant volume in a fully equipped vehicle with a functioning heater would exceed the stated capacity.
- The Robin 750 and Robin 750 Van, covering 1972-1975, share an identical 2.84-liter (+ heater) cooling system capacity, indicating no differentiation between the saloon and van body configurations for that engine displacement.
- The Robin 850 and Robin 850 Van, covering 1975-1981, also share the same 2.84-liter (+ heater) capacity as the earlier 750 variants, meaning the displacement increase from 750cc to 850cc did not alter the specified cooling system volume.
- All four rows are assigned a normal use condition, meaning the capacity figures apply under standard operating circumstances rather than severe-duty or first-fill scenarios.
