Peugeot 304

Coolant capacity & service interval

Peugeot 304 uses coolant with a capacity range of 5,8 to 6,5 liters. Service intervals require a check every 2500 km. The data covers 5 configurations.

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

Additional Notes

  • The Peugeot 304 petrol variants, spanning the 1969-1975 and 1976-1980 production periods, share an identical cooling system capacity of 5.8 liters, as do both 304 S sub-variants from 1972-1975 and 1976-1980.
  • The 304 Diesel (1977-1980) carries a cooling system capacity of 6.5 liters, which is 0.7 liters greater than the 5.8-liter figure recorded across all petrol configurations.
  • A diesel engine generally produces more heat per combustion cycle than a comparable petrol unit, and the larger 6.5-liter coolant capacity in the 304 Diesel reflects the greater thermal load placed on the cooling circuit.
  • The 304 Diesel (1977-1980) is the only configuration in the specifications to carry a defined check interval, set at every 2,500 km under normal use conditions.
  • A 2,500 km check interval for coolant level is a relatively short monitoring cycle, indicating that the cooling system in the 304 Diesel warranted more frequent attention compared to the petrol variants, for which no equivalent interval is listed.
  • The 304 S trim, introduced in 1972, shares the same 5.8-liter cooling system capacity as the base 304, with no variation in coolant volume between the two across any overlapping model year period.
