Additional Notes
- The Citroën SM 2.7 V6 carries a coolant system capacity of 13 liters, which is consistent with a full cooling system fill encompassing the radiator, engine block passages, heater core circuit, and expansion reservoir.
- The 13-liter figure applies to the 1970-1972 model years of the 2.7 V6 configuration, representing the total volume required when refilling a fully drained system rather than a partial top-up.
- The listed use condition for the 1970-1972 2.7 V6 coolant specification is normal, meaning the 13-liter capacity value corresponds to standard operating conditions rather than a severe-duty or first-change-only service scenario.
