Proton Inspira

Coolant capacity & service interval

Proton Inspira coolant capacity ranges from 0,65 to 7 liters. Service intervals include checks at 20000 km or 12 months, and changes at 120000 km or 72 months and 180000 km or 108 months. The data covers 4 configurations.

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

Additional Notes

  • The Proton Inspira cooling system holds 7 liters as the main circuit capacity, which represents the full system fill volume used when servicing or refilling the cooling circuit.
  • A separate reserve tank capacity of 0.65 liters is specified alongside the main 7-liter figure, reflecting the overflow or expansion reservoir that sits outside the primary circuit.
  • Both the 1.8 and 2.0 engine variants share identical capacities of 7 liters for the main system and 0.65 liters for the reserve tank, indicating no displacement-related difference in cooling system volume.
  • The check interval for both engine variants is set at 20,000 km or 12 months, whichever comes first, applying under normal use conditions.
  • Under normal use, the coolant change interval is 120,000 km or 72 months for both the 1.8 and 2.0 variants.
  • A first change only condition extends the coolant change interval to 180,000 km or 108 months, which is 60,000 km and 36 months longer than the standard normal use interval.
  • The first change only interval of 108 months equals 9 years, meaning the initial factory-fill coolant in both engine variants is rated for a significantly longer service life before the first replacement is due.
