Additional Notes

  • The Alfa Romeo Montreal 105 cooling system holds 12 liters of coolant, a capacity consistent with a full system fill covering the engine, radiator, heater core, and all associated passages.
  • Under normal use conditions, the coolant change interval is set at 30,000 km or 12 months, whichever comes first, meaning calendar time alone can trigger a service even when mileage accumulation is low.
  • The 12-month time limit on the coolant interval reflects the chemical degradation of antifreeze and corrosion inhibitors over time, independent of distance driven.
  • A single specification applies across the entire 1970-1977 production span of the Montreal 105, with no variation in capacity or interval recorded across those model years.
