Additional Notes
- The Mazda Capella/616 1600 SNA, covering 1973-1978, carries a cooling system capacity of 7 liters, which represents the total volume of the cooling circuit including the radiator, engine block passages, and heater core.
- The CB-generation 1600 engine, spanning 1978-1983, retains the same 7-liter cooling system capacity as the earlier SNA-generation 1600, despite the model transition between generations.
- Moving to the larger displacement CB variants, both the 1800 and 2000 engines share a cooling system capacity of 7.5 liters, a half-liter increase over the 1600 CB, consistent with the greater coolant jacket volume required by larger engine displacements.
- Across all four configurations, the specified service interval is 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first triggers a coolant change.
- The 24-month time limit on the coolant change interval reflects the degradation of corrosion inhibitors in conventional coolant formulations, which lose effectiveness over time regardless of distance traveled.
- All four configurations carry a normal use designation, meaning the stated 40,000 km / 24-month interval applies to standard operating conditions rather than a reduced severe-duty schedule.
