Mitsubishi Celeste (EU)

Coolant capacity & service interval

Mitsubishi Celeste (EU) requires coolant with a capacity of 6,5 liters. The service interval is 40000 km or 24 months. The data covers 2 configurations.

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

TypeSpecifications

Celeste 2000, A78 (1975-1980)
  • Use: Normal
  • Capacity 6,5 liter
  • Change 40000 km/ 24 months

Additional Notes

  • Both the Celeste 1600 (A73) and Celeste 2000 (A78) share an identical cooling system capacity of 6.5 liters, which represents the total volume of coolant the system holds when filled during a standard service.
  • A 6.5-liter cooling system capacity is a moderate figure for passenger cars of the mid-to-late 1970s, consistent with engines in the 1.6 to 2.0-liter displacement range that rely on liquid cooling without auxiliary reservoir overflow systems of larger volume.
  • The Mitsubishi Celeste (EU) coolant change interval is set at 40,000 km or 24 months under normal use conditions, meaning whichever threshold is reached first triggers the scheduled replacement.
  • The 24-month time limit on the coolant change interval reflects the chemical degradation of antifreeze and corrosion inhibitors over time, which occurs independently of mileage accumulation.
  • The normal use condition tied to the 40,000 km / 24-month interval applies equally across both the A73 and A78 variants, with no differentiation in service scheduling between the two engine configurations for the 1975-1980 production period.
