Additional Notes
- The Opel Monterey B 3.0 TD carries a cooling system capacity of 8.6 liters, which is 0.1 liters greater than the 8.5-liter capacity specified for the 3.5 V6 variant across the same 1998-2000 model years.
- A cooling system capacity in the 8.5-8.6 liter range is consistent with a full system fill, accounting for the radiator, engine block passages, heater core circuit, and overflow reservoir volume combined.
- The 3.5 V6 specification includes a coolant check interval of 15,000 km under normal use conditions, meaning the coolant level and condition are to be inspected at each 15,000 km service point.
- Both the 3.0 TD and 3.5 V6 specifications are listed under normal use conditions, which in service interval terminology refers to standard operating environments as opposed to severe or heavy-duty duty cycles.
- No check interval figure appears in the 3.0 TD row, whereas the 3.5 V6 row carries the 15,000 km check interval alongside its 8.5-liter capacity value.
