Additional Notes
- The Proton Persona 1.6 cooling system holds a capacity of 5 liters, which represents the total volume of the cooling circuit including the radiator, engine block passages, heater core, and reservoir.
- A 5-liter cooling system capacity is on the moderate end for a 1.6-liter displacement engine, reflecting a reasonably sized thermal management circuit designed to maintain stable operating temperatures across the engine's components.
- The capacity figure of 5 liters applies under normal use conditions, meaning a standard drain-and-refill service rather than a pressure-flush or full overhaul procedure, which would typically require accounting for residual fluid left in the system.
