Alfa Romeo SZ, RZ, 162 (EU)

Coolant capacity & service interval

Alfa Romeo SZ, RZ, 162 (EU) models require 10 liter of coolant. Service intervals include checking every 500 km and changing every 60000 km or 24 months. The data covers 2 configurations.

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

TypeSpecifications

  • Change 60000 km/ 24 months

Additional Notes

  • The Alfa Romeo SZ (1989-1991) and RZ (1992-1994) share an identical cooling system capacity of 10 liters, which represents a full system fill volume rather than a partial top-up quantity.
  • A 500 km check interval applies to both the SZ and RZ cooling systems under normal use conditions, reflecting a relatively short early inspection cycle for verifying coolant level and system integrity after servicing.
  • The change interval for both configurations is set at 60,000 km or 24 months under normal use, meaning whichever threshold is reached first would govern when a coolant replacement is due.
  • The 24-month time-based limit on the change interval acknowledges that coolant degrades chemically over time regardless of distance driven, making calendar time an independent trigger alongside mileage.
  • No variation in capacity or service intervals exists between the SZ and RZ despite the two models occupying different production periods within the 1989-1994 span, as both are rated identically across all three specification points.
