Additional Notes

  • The Mazda 5 CR 2.3 cooling system holds 6.9 liters as the standard fill capacity across all listed model years and markets. When the heater circuit is included in the fill, the total rises to 7.5 liters, reflecting the additional coolant volume held within the heater core and its associated hose circuit.
  • The 0.6-liter difference between the base capacity and the heater-inclusive capacity is consistent across every row in the specifications, applying equally to both USA and CAN variants from 2005-2010.
  • For the 2005-2006 model years in both USA and CAN markets, the normal-use change interval is 60,000 miles or 60 months. A separate first-change-only condition extends the initial drain interval to 120,000 miles or 120 months, meaning the very first coolant change is deferred significantly beyond the standard recurring interval.
  • The first-change-only interval of 120,000 miles or 120 months is associated with long-life coolant formulations, which are factory-filled and designed to remain in service longer before the initial drain. After that first change, the 60,000-mile or 60-month normal interval applies.
  • The 2006-2009 CAN and USA configurations carry the same dual-interval structure as the 2005-2006 entries, with a normal interval of 60,000 miles or 60 months and a first-change-only interval of 120,000 miles or 120 months.
  • The 2009-2010 entries for both USA and CAN markets use different interval terminology compared to earlier years. Rather than "normal" and "first change only," the specifications reference "initial service" and "subsequently," which describe the same sequential relationship: a longer first interval of 120,000 miles or 120 months, followed by recurring changes at 60,000 miles or 60 months.
  • The shift in terminology between the 2006-2009 and 2009-2010 rows, from "first change only / normal" to "initial service / subsequently," represents a labeling difference in how the same two-phase interval structure is expressed, with the underlying mileage and month values remaining unchanged at 120,000 or 120 months for the first service and 60,000 or 60 months thereafter.
  • Capacity figures are identical across USA and CAN market variants for every model year listed, indicating no market-specific cooling system volume differences for the 2.3-liter engine in the Mazda 5 CR.
