Additional Notes

  • The Proton Waja / Impian 1.6 cooling system holds 5 liters of coolant, a figure that reflects the total system fill capacity rather than a partial top-up volume.
  • Under normal use conditions, the coolant inspection interval for the 1.6 is set at every 9,000 miles or 12 months, whichever comes first.
  • The coolant change interval under normal use is 27,000 miles or 36 months, meaning a full drain and refill is expected roughly every three years at standard driving conditions.
  • The ratio between the check interval and the change interval follows a 1:3 pattern, with three inspection cycles completing before a full coolant replacement is due.
