Proton Persona / Persona Compact
Coolant capacity & service interval
Proton Persona / Persona Compact coolant capacity ranges from 5 to 6 liters. Service intervals include checks at 20000 km and changes at 40000 km or 24 months. The data covers 3 configurations.

Additional Notes
- The Proton Persona / Persona Compact cooling system capacity varies by engine displacement, with the 1.3 and 1.5 variants holding 5 liters and the 1.6 variant holding 6 liters.
- The 1.6 engine's 6-liter cooling system capacity is 20% greater than the 5-liter figure shared by the 1.3 and 1.5 engines, reflecting the larger displacement's greater thermal load and block volume.
- The 1.3 engine configuration applies to model years 1996-2006, while both the 1.5 and 1.6 engine configurations cover the wider span of 1993-2006.
- All three engine variants share an identical coolant check interval of 20,000 km under normal use conditions, regardless of engine size or model year.
- The coolant change interval across all three configurations is 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first would trigger a service event.
- The dual-criterion change interval of 40,000 km or 24 months acknowledges that coolant degrades both through use and through time-based chemical breakdown, even in low-mileage operation.
- The check interval of 20,000 km falls at exactly half the 40,000 km change interval, placing one inspection midway between each full coolant replacement across all listed configurations.
