Additional Notes
- The Holden Commodore/Calais VK cooling system capacity splits clearly along engine lines, with six-cylinder variants holding 8.5 liters and V8 variants holding 12 liters across the 1984-1986 model range.
- The 8.5-liter cooling system capacity applies to the Calais EFI, Commodore SL/Berlina, and Commodore SL/Berlina EFI, indicating a shared cooling system architecture across both carbureted and fuel-injected six-cylinder configurations.
- A 12-liter cooling system capacity is specified for both the Calais V8 and Commodore SL/Berlina V8, reflecting the greater thermal load and larger engine block volume associated with V8 engines.
- The difference between 8.5 liters and 12 liters represents a 41 percent increase in coolant volume when moving from a six-cylinder to a V8 configuration, which is consistent with the larger displacement and additional cylinder count requiring more heat dissipation capacity.
- All five configurations carry a normal use condition designation, meaning the specified capacities apply to standard operating environments rather than severe-duty or high-stress service conditions.
- The Commodore SL/Berlina and Commodore SL/Berlina EFI share an identical 8.5-liter cooling system capacity, indicating the addition of electronic fuel injection on the SL/Berlina did not alter the cooling system volume requirement for that trim.
