Additional Notes
- The Bentley R Type's cooling system capacity varies by configuration, with the standard 4½-litre variant requiring 18.2 liters of coolant under normal use conditions.
- Both the Type R Continental (1954-1955) and the Type R Continental 4½-litre (1952-1954) share an identical cooling system capacity of 17.05 liters under normal use conditions.
- The standard Type R 4½-litre (1952-1955) holds 1.15 liters more coolant than either Continental variant, a difference that typically reflects a larger or differently routed cooling circuit rather than a change in engine displacement.
- A coolant capacity in the 17-18 liter range is characteristic of large-displacement engines from this era, where extended cooling passages and separate header tanks were common design features.
- All three configurations carry a normal use condition designation, meaning the stated capacities apply to standard operating environments rather than a modified or severe-duty service context.
