Diesel maintenance notes for this vehicle
- Oil Level Verification: Always check the oil level after refilling to ensure it meets the required capacity.
- Cooling System: Maintaining a robust cooling system is vital for diesel longevity. If using concentrated antifreeze (like ANT1G-EA), it must be mixed with distilled or high-quality water.
- Filter Maintenance: Using premium media filters, such as the WIX 51626-EA, can help reduce engine wear and offer OEM drain intervals.

Common maintenance concerns for this vehicle
Owners of the Peugeot 504 diesel should prioritize the following:
- Cooling System Integrity: Given the importance of cooling for diesel longevity, regular checks of gaskets and hoses are recommended.
- Drivetrain Torque: The architecture includes a torque tube driveshaft; ensure undercarriage maintenance is performed with this design in mind.
- Fuel Quality: Diesel maintenance is highly sensitive to fuel quality and timing settings.
Recall, TSB, and manufacturer communication notes
Official NHTSA recall research for the 1983 Peugeot 504 returned no records. However, this does not prove the vehicle has no issues; it only means no complaints were found in this specific database search. Owners should always verify open recalls by VIN through an official manufacturer or dealership portal.
About this vehicle
The 1983 Peugeot 504 represents a significant era for the model, which began its highly successful production run in 1968. As a mid-size, front-engine, rear-wheel-drive vehicle, the 504 was engineered with a focus on robustness and durability. It is famously characterized by its long suspension travel and high ground clearance, features that contributed to its widespread popularity in rugged environments across Africa and Latin America.
This specific model is equipped with a 2.3L diesel engine, part of a lineage known for being “workhorses” capable of handling difficult terrain. The drivetrain architecture includes a torque tube driveshaft designed to relieve drivetrain torque reactions, which is a relevant consideration for owners performing undercarriage or drivetrain maintenance. Because the 504 was produced globally through various licensing arrangements (including significant assembly in Nigeria and Kenya), parts availability and regional variations may exist.
Maintenance focus should remain on the robust body structure and the cooling system, which is vital for diesel longevity. Owners of this displacement should verify exact compression ratios and fuel injection requirements, as diesel maintenance is highly sensitive to fuel quality and timing settings.
