Proton GEN-2 / Persona

Coolant capacity & service interval

Proton GEN-2 / Persona uses coolant with a capacity of 5 liters. Service intervals include checks at 9000 miles or 12 months and changes at 27000 miles or 36 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Proton GEN-2 / Persona cooling system capacity is 5 liters across the 1.3, 1.6, and 1.6 ecologic variants introduced in 2004, indicating a full system fill volume rather than a partial or overflow-only figure.
  • The 1.3 and 1.6 engine variants share an identical 5-liter cooling system capacity, meaning no displacement-related difference exists in the coolant volume required for either configuration.
  • The 1.6 ecologic variant also carries a 5-liter cooling system capacity, placing it in alignment with the standard 1.6 despite the differing engine designation.
  • A coolant check interval of 9,000 miles or 12 months applies under normal use conditions across all three variants, reflecting a routine inspection frequency rather than a drain-and-refill service.
  • The coolant change interval is set at 27,000 miles or 36 months under normal use conditions, meaning a full drain and refill is expected at three times the frequency of the check interval in mileage terms.
  • The 36-month change interval translates to a three-year replacement cycle, which is consistent with conventional coolant formulations that degrade in corrosion inhibitor effectiveness over time regardless of mileage accumulation.
  • All three configurations share the same check and change intervals, indicating no variant-specific deviation in service scheduling for the cooling system starting from the 2004 model year.
