Peugeot 604

Coolant capacity & service interval

Peugeot 604 coolant capacity ranges from 10 to 10,3 liters. Service intervals include checks at 5000 km or 1 month, checks at 7500 km or 1 month, and changes every 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Peugeot 604 D Turbo (1978-1985) carries a cooling system capacity of 10 liters, while the 604 SL (1975-1985) and 604 Ti (1977-1985) each hold 10.3 liters, placing the diesel turbocharged variant 0.3 liters below the two petrol configurations.
  • The 604 D Turbo cooling system calls for a check interval of every 5,000 km or 1 month under normal use conditions, a notably shorter distance interval than the 7,500 km specified for both the 604 SL and 604 Ti under the same conditions.
  • All three variants share a 24-month coolant change interval under normal use, meaning the fluid is replaced on a calendar basis regardless of mileage accumulated within that period.
  • The monthly check frequency applied across all three variants, regardless of the km interval, reflects a time-based minimum that operates independently of driving distance, so low-mileage use does not extend the period between inspections beyond one month.
  • The 604 SL and 604 Ti share identical cooling system specifications in both capacity (10.3 liters) and check interval (7,500 km / 1 month), despite the Ti entering production two years later in 1977 compared to the SL's 1975 start date.
