Additional Notes

  • All six configurations of the Mazda CX-7 ER (EU) share a cooling system capacity of 9 liters, a figure consistent with a full system service fill covering the engine block, cylinder head passages, radiator, and associated hoses rather than a partial top-up volume.
  • The 2.3 DISI Turbo variants, covering model years 2007-2012 across both manual and automatic transmission configurations, carry a coolant change interval of 195,000 km or 132 months under normal use conditions.
  • The 2.2 CiTD diesel variants, available in 120 kW and 127 kW outputs for 2009-2012, share a slightly longer coolant change interval of 200,000 km or 132 months under normal use conditions, matching the interval specified for the 2.5-liter petrol engine.
  • The time-based change interval of 132 months applies uniformly across all six configurations regardless of engine type, equating to 11 years between coolant changes under normal use conditions.
  • The check interval for the 2.2 CiTD and 2.5-liter configurations is set at 40,000 km or 24 months under normal use conditions, while the 2.3 DISI Turbo configurations specify a shorter distance-based check interval of 30,000 km at the same 24-month time interval.
  • The 2.3 DISI Turbo automatic transmission configuration spans the full 2007-2012 model year range as a single entry, carrying the same 9-liter capacity and 195,000 km change interval as the non-automatic 2.3 DISI Turbo entries.
