Additional Notes

  • Across all Peugeot J9 configurations listed, the coolant change interval is set at 24 months regardless of engine type or body variant, reflecting a time-based rather than mileage-based replacement schedule typical of older coolant formulations from the era.
  • The check interval of 2,500 km applies uniformly across every J9 configuration listed, a relatively short inspection cycle consistent with commercial vehicle maintenance practices of the 1980s and early 1990s.
  • The petrol engines — the 1.6 and 2.0 — carry a cooling system capacity in the 8.5 to 9 litre range, with the 1.6 showing a slight spread of 8.5–9 litres across the 1500 and 1900 body variants, while the 2.0 is fixed at 8.5 litres across both its 1985-1988 and 1989-1992 model year ranges.
  • The diesel engines — the 2.1 D and 2.5 D — both require 10.7 litres of coolant, a notably higher figure than the petrol units. The larger cooling system capacity in diesel engines generally reflects the greater thermal load produced by compression-ignition combustion and the additional cooling demands of components such as the oil cooler.
  • The 2.1 D and 2.5 D share an identical 10.7 litre capacity despite the displacement difference between them, suggesting a shared or closely related cooling circuit architecture across the J9 diesel range for the 1985-1988 period.
  • The 2.0 petrol and 2.5 D diesel both carry specifications into the 1989-1992 model year range, each retaining the same capacity and service intervals as their 1985-1988 counterparts, indicating no revision to cooling system specifications across the production period covered.
