Additional Notes

  • The Alfa Romeo Tonale 1.3 PHEV cooling system holds 5.6 liters, while the separate high voltage system circuit adds another 7 liters, meaning the powertrain as a whole manages two distinct coolant volumes rather than a single shared loop.
  • The 1.3 PHEV high voltage system capacity of 7 liters is notably larger than the standard combustion cooling system capacity of 5.6 liters, reflecting the thermal management demands of the battery and electric drive components.
  • The Tonale 2.0 carries a 6.6-liter main cooling system capacity, which is higher than the 1.3 PHEV combustion circuit at 5.6 liters, consistent with the greater displacement and heat output of the 2.0-liter engine.
  • A separate low temperature circuit on the Tonale 2.0 holds 2.2 liters. Low temperature circuits typically serve charge air coolers or transmission oil coolers, operating at a lower thermal range than the main engine circuit.
  • All four coolant circuit entries across both the 1.3 PHEV and 2.0 share an identical service interval of 150,000 miles or 120 months under normal use conditions, placing the change interval at a 10-year or high-mileage threshold.
  • The 120-month interval equals a full decade of service life before a coolant change is specified, which is consistent with modern long-life coolant formulations designed to maintain corrosion inhibitor effectiveness over extended periods.
