Additional Notes
- The Peugeot J7's petrol variants, the 1.6 PZ10 and 1.8 PZ20, share an identical cooling system capacity of 8.5 liters across the full 1970-1980 production span.
- Both diesel variants, the 2.1D PZ50 and 2.3D PZ60, carry a notably larger cooling system capacity of 10.7 liters, reflecting the greater thermal mass and heat rejection demands typical of diesel engines compared to petrol units of similar displacement.
- The 2.5-liter difference in coolant capacity between the petrol and diesel configurations represents a meaningful distinction when preparing the correct volume of coolant mixture for a service fill.
- All four variants share a uniform coolant change interval of 24 months under normal use conditions, regardless of engine type or displacement.
- The petrol variants specify a check interval of every 7,500 km or 1 month, whichever comes first, under normal use conditions.
- The diesel variants specify a considerably shorter check interval of every 2,500 km under normal use conditions, which is less than a third of the distance interval applied to the petrol variants.
- The diesel variants, the PZ50 and PZ60, entered the specification range only from 1978, while the petrol variants cover the entire 1970-1980 period.
