Additional Notes

  • The Vauxhall Monaro cooling system capacity is 12 liters across all listed configurations, covering the 5.7 V8, 5.7 VXR, and 6.0 VXR variants from 2004-2006.
  • A 12-liter cooling system capacity is a relatively large figure, consistent with the demands of a high-displacement V8 engine requiring substantial coolant volume to manage heat across the block, heads, and radiator circuit.
  • The coolant change interval is set at 240,000 km under normal use conditions for every listed configuration, which is an extended-life service interval typically associated with modern long-life coolant formulations.
  • The 240,000 km interval applies uniformly to both the 5.7 V8 and 5.7 VXR variants in the 2004-2005 model year, with no differentiation between the standard and performance-oriented trim in terms of coolant service scheduling.
  • The 6.0 VXR from 2005-2006, despite having a larger displacement engine than the 5.7 variants, shares the same 12-liter capacity and 240,000 km change interval under normal use conditions.
  • The 5.7 V8 spans two overlapping production periods in the specifications, covering 2004-2005 and 2005-2006, with both periods carrying identical capacity and interval figures of 12 liters and 240,000 km respectively.
