Additional Notes
- The Vauxhall Monterey A front differential holds 1.5 liters of fluid across both the 3.1 TD and 3.2 V6 engine variants, while the rear differential holds 1.8 liters in each case, reflecting the larger housing typical of a rear axle unit.
- The 0.3-liter difference between front and rear differential capacities is consistent across both engine configurations, indicating a shared axle architecture between the 3.1 TD and 3.2 V6 models.
- All four differential positions across both engine variants share an identical check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
- The change interval for differential fluid on all listed configurations is 45,000 km or 36 months under normal use, meaning a full drain and refill is due every three years or three check cycles.
- The 3.2 V6 variant carries a starting year of 1991, one year earlier than the 3.1 TD, which begins in 1992, though both share the same differential fluid capacities and service intervals throughout their respective production spans.
