Additional Notes
- The Rover 45 1.4 16V cooling system carries a dry fill capacity of 5.3 liters, while the service fill capacity drops to 4.6 liters, reflecting the volume of coolant that remains trapped in the engine block and heater circuit during a routine drain.
- The 1.8 16V variant holds a dry fill capacity of 5.5 liters against a service fill of 4.8 liters, making the difference between a full overhaul fill and a routine service fill 0.7 liters for that engine.
- The 2.0 V6 24V shows a dry fill capacity of 5.75 liters and a service fill of 4.8 liters, meaning the V6 requires slightly more coolant than the 1.8 16V when filling from completely dry, yet the two engines share the same 4.8-liter service fill figure.
- The 2.0 TD diesel engine carries the largest cooling system capacity across the Rover 45 range, with a dry fill of 7.0 liters and a service fill of 6.3 liters, consistent with the greater thermal load that diesel engines typically generate.
- The 1.6 16V is the only engine in the range with a single listed capacity of 4.6 liters, without a separate dry fill figure, placing the 1.6 16V at the lowest overall coolant volume among the five engines.
- All five engine variants share a uniform coolant change interval of 24 months, applied under the use condition starting from 2000 onward.
