Additional Notes
- The Vauxhall Senator B, V88 coolant system capacity varies by engine, ranging from 9.8 liters at the low end for the 3.0i 24V to 10.5 liters for the 2.6i.
- The 2.5i, covering model years 1987-1993, carries a capacity range of 10.1-10.3 liters, which reflects minor variation likely attributable to differences in cooling circuit configuration or fill method across production.
- The 2.6i, introduced for the 1990-1993 period, holds the highest single stated capacity across all four configurations at 10.5 liters.
- The 3.0i 24V, available from 1989-1993, has the widest capacity spread of any listed configuration, spanning 9.8-10.4 liters, a range of 0.6 liters that suggests meaningful variation in fill volume depending on conditions or procedure.
- The 3.0i, running across the full 1987-1993 span, carries a fixed capacity of 10.1 liters with no stated range, indicating a consistent fill volume for that engine.
- All four configurations share an identical service interval of 24 months under normal use conditions, meaning coolant replacement is time-based rather than mileage-driven across the entire Senator B, V88 lineup.
