Additional Notes
- The Peugeot 604's power steering system holds 0.79 liter as the total system capacity across the 604 D Turbo, 604 SL, and 604 Ti variants.
- A separate steering pump capacity of 0.65 liter is specified alongside the full system figure, reflecting the fluid volume held within the pump assembly alone rather than the entire hydraulic circuit.
- The difference between the 0.79 liter system capacity and the 0.65 liter pump capacity amounts to 0.14 liter, which represents the fluid distributed through the remaining lines and components outside the pump itself.
- All three variants share an identical service interval of 15,000 km for a fluid level check under normal use conditions, with no variation across the 604 D Turbo (1978-1985), 604 SL (1975-1985), or 604 Ti (1977-1985).
- The 15,000 km interval is designated as a check rather than a full fluid replacement, meaning the service action involves inspecting and topping up the fluid level rather than draining and refilling the system.
- The 604 SL carries the earliest start year among the three variants at 1975, while the 604 Ti entered the specification from 1977 and the 604 D Turbo from 1978, yet all three share the same capacity and interval figures throughout their respective production spans.
