Mazda 5, CW (USA / CAN)

Coolant capacity & service interval

Mazda 5, CW (USA / CAN) uses coolant with a capacity of 6,6-6,7 liters. Service intervals consist of 60000 miles/60 months and 120000 miles/120 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Mazda 5 CW 2.5 cooling system holds 6.6 to 6.7 liters of coolant across both the USA and CAN configurations for 2011-2015, a capacity range that reflects a service fill level rather than a full overhaul drain-and-refill volume.
  • Under normal use conditions, the coolant change interval for the 2.5 engine is set at 60,000 miles or 60 months, whichever comes first, applying equally to both the USA and CAN markets.
  • A separate first change only interval of 120,000 miles or 120 months is specified alongside the normal interval, meaning the initial factory-fill coolant is rated to last twice as long before the first scheduled replacement.
  • The identical capacity figure of 6.6 to 6.7 liters across both the USA and CAN variants of the 2.5 engine indicates no market-specific difference in cooling system volume for 2011-2015.
  • The 60-month time limit paired with the 60,000-mile mileage interval means coolant degradation is treated as time-dependent as well as mileage-dependent under normal use conditions.
