About this vehicle
The 1982 Peugeot 604 represents a significant era in Peugeot’s history as an executive-class manufacturer. Produced between 1975 and 1985, the 604 was designed to compete in the large luxury saloon market, featuring styling by Pininfarina that was noted for its ‘calm elegance.’ While many 604 models were equipped with the PRV V6 engine, this specific vehicle features a 2.3L 4-cylinder diesel configuration (Engine Code: XD2S). This indicates a focus on durability and fuel efficiency, aligning with Peugeot’s reputation for robust diesel engineering during this period.
The 604 was built upon design principles shared with the Peugeot 504, utilizing similar components such as the bulkhead, doors, and portions of the floorpan. Because it shares architectural DNA with the highly successful 504—a vehicle renowned for its high ground clearance and robust body structure—owners may find overlapping mechanical logic in suspension and chassis components. However, because the specific technical details regarding the XD2S turbo diesel engine are not fully detailed in all research snippets, owners should verify exact displacement and turbocharger specifications through a workshop manual before performing deep engine work.
Maintenance for this vehicle typically focuses on preserving the longevity of the diesel injection system and managing the cooling requirements of a turbocharged engine. Given the vehicle’s age, attention to rubber components, seals, and fluid integrity is paramount. Because this era of Peugeot transitioned between different manufacturing standards, verifying part compatibility for the XD2S engine family is a critical first step in any service routine.
Recall, TSB, and manufacturer communication notes
Official NHTSA recall research for the 1982 Peugeot 604 returned no recall records. Additionally, no NHTSA complaint records were found for this specific year/make/model combination. However, these results do not prove the vehicle has no issues; they only indicate that no records were returned by the API search. Owners should always verify open recalls by VIN, as applicability depends on production date and equipment.
