Peugeot 504 Coupé/Cabriolet

Differential fluid capacity & service interval

Peugeot 504 Coupé/Cabriolet differential fluid capacity ranges from 1,2 to 1,6 liters. Service intervals include checking at 5000 km or 7500 km and changing at 15000 km or 30000 km. 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 504 Coupé/Cabriolet produced in 1969-1971 carries a rear differential fluid capacity of 1.2 liters, which represents the service fill volume for routine maintenance on that generation.
  • From 1971 onward, the rear differential capacity increases to 1.6 liters, a figure shared across both the standard Coupé/Cabriolet and the 504 V6 Coupé variants through 1983.
  • The 1969-1971 specification calls for a differential fluid check every 5,000 km under normal use conditions, a notably shorter interval than what later configurations require.
  • The change interval for the 1969-1971 rear differential is set at 15,000 km under normal use, which is half the 30,000 km drain interval specified for the 1971-1983 configuration.
  • Both the 1971-1983 standard Coupé/Cabriolet and the 504 V6 Coupé share identical rear differential service intervals, with fluid checks at 7,500 km and changes at 30,000 km under normal use conditions.
  • The doubling of the change interval between the 1969-1971 and 1971-1983 specifications, from 15,000 km to 30,000 km, reflects a meaningful revision in the rear differential service schedule across the model's production span.
