Alfa Romeo SZ, RZ, 162 (EU)

Brake fluid capacity & service interval

Alfa Romeo SZ, RZ, 162 (EU) models utilize brake fluid with a capacity of 0,5 liter. Service intervals include a check every 500 km and a change every 12 months. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Change 12 months

Additional Notes

  • The Alfa Romeo SZ (1989-1991) and RZ (1992-1994) share an identical brake fluid capacity of 0.5 liter for the hydraulic brake/clutch system, which is a relatively modest reservoir volume consistent with a combined brake and clutch circuit rather than separate dedicated systems.
  • Both configurations specify a check interval of 500 km, which is a notably short distance-based inspection cycle, reflecting the safety-critical nature of brake fluid condition monitoring in a shared hydraulic circuit.
  • The change interval for both the SZ and RZ is set at 12 months under normal use conditions, meaning fluid replacement is time-based rather than mileage-based, which accounts for the hygroscopic nature of brake fluid absorbing moisture over time regardless of distance driven.
  • The 0.5 liter capacity figure applies to the hydraulic brake/clutch system as a whole, meaning the reservoir serves both functions simultaneously, and a service fill would draw from that single shared volume.
  • The SZ and RZ are treated as distinct model entries despite sharing identical fluid capacity and service interval specifications, with the SZ covering 1989-1991 and the RZ covering 1992-1994.
