Additional Notes
- The Vauxhall Monterey B, M98 cooling system capacity differs slightly between engine variants, with the 3.0 TD holding 8.6 liters and the 3.5 V6 holding 8.5 liters.
- A cooling system capacity in the 8.5–8.6 liter range reflects a full system fill, accounting for the radiator, engine block passages, heater core, and associated hoses rather than a partial or top-up volume.
- Both the 3.0 TD and the 3.5 V6 share the same check interval of every 15,000 km or 12 months, whichever comes first, under normal use conditions.
- The 12-month time-based interval alongside the 15,000 km distance interval means a coolant check is due on whichever threshold is reached first, which is standard practice for vehicles that may accumulate lower annual mileage.
- Both engine configurations covered in the 1998-2000 period carry a "normal" use condition designation, meaning the stated 15,000 km or 12-month check interval applies to standard operating environments rather than more demanding ones.
